Operator CLI

tripl is a small command-line client for a tripl instance. Most of it talks to a running instance over HTTP; two commands instead act on a directory and the local Docker daemon, and those are the ones that bring an instance into existence in the first place.

Four commands ask a question about the instance as a whole and change nothing:

• tripl doctor — runs six diagnostic checks and tells you what is broken, why, and what to do about it. Exits non-zero when something is wrong.
• tripl status — a quick live view of every project: events, scan configs, open signals, firing monitors, reconciliation coverage. Always exits 0.
• tripl watch — follow mode. Prints what changes while you watch: replay chunk progress, jobs starting and finishing, signals opening, alert deliveries failing. Runs until you stop it. Never reports a verdict.
• tripl whoami — which account the configured key acts as, the organization it is bound to, and its scope. See tripl whoami.

Two more act on a class of objects and are spelled <plural-noun> <verb>:

• tripl scans — list the scan configurations, print one's jobs, run one now, cancel an active job.
• tripl drifts — list schema drifts, dismiss one, reopen one.

One more records a single fact about a project and is one word:

• tripl annotate — post a deploy or release marker onto every monitoring (Volume tab) chart in a project, from a CI step. See tripl annotate.

scans run, scans cancel, drifts dismiss, drifts reopen and annotate are the CLI's only mutating commands. Read Write safety before you use one. Every other command that talks to an instance is read-only, and a tk_r_ key is enough for all of them.

Two more are read-only in full, and answer questions about the content rather than the machinery:

• tripl events — list the catalog with the API's own filters, show one event with its field values resolved to field names.
• tripl plan — the shape events are declared to have: types, one type's fields, the documented variables, the plan branches, and search across all of it.

Both read one project at a time, so both need --project SLUG exactly once, and every verb but plan branches takes --branch to read a plan branch instead of the live main plan.

One more checks your code against the plan, and is one word:

• tripl check — scans source files for tracking calls, or reads a file of captured events, and reports unknown events, unknown fields, missing required fields and values the plan does not allow. Built for a CI step, with SARIF output for code scanning. See tripl check.

It sends a POST, but only to carry the calls it found to the validator: it changes nothing, and a tk_r_ key is enough.

Two more turn the plan into files in your repository. Both only read the instance; the files they write are local:

• tripl codegen — generates typed Swift, Kotlin and TypeScript tracking code from the plan, on top of your own tracking wrapper, with a --check mode for CI. See tripl codegen.
• tripl export — writes the plan as a JSON Schema bundle, one schema per event, or as the model tripl codegen --model reads. See tripl export.

Two act on a host, not on an instance — no URL, no API key, no HTTP except a /health poll at the end:

• tripl install — writes compose.yaml, infra/rabbitmq/rabbitmq.conf and a generated 0600 .env into a directory, runs docker compose pull and docker compose up -d in it, and waits until the instance answers. This is the executable form of Self-hosting & Deployment.
• tripl upgrade — moves an installed stack to a new image tag: pull, move the TRIPL_VERSION pin, restart, wait.

Everything that talks to an instance is a pure HTTP client of the /api/v1 surface, exactly like the MCP server — it imports no backend code and never touches the database. Since the two tools now share one request layer, a path or a response projection is defined in exactly one place for both. They also read the same two environment variables, so a shell configured for one is configured for the other. install and upgrade are the exception in both directions: they run a subprocess (docker), and they read neither variable.

What this page is for

tripl doctor exists because of a four-day incident in which a scan config had been failing behind a generic "Scan failed due to an internal error", events' last_seen_at had frozen with no visible cause, an accepted schema drift had silently deleted a field definition, and the scheduler's retry backoff looked like a hung worker. Every one of those was visible through read-only REST calls. This is the one invocation that surfaces them.

Install

The only runtime dependency is httpx. Python 3.12 or newer is required for the pip path only — every uv-driven form below (uvx, and the uv run --project checkout form) provisions a suitable interpreter itself, so a host carrying uv and no Python at all still runs the CLI.

From PyPI. tripl is published, so this is the ordinary path:

uvx tripl doctor      # run it without installing anything permanently
pip install tripl     # or put it on PATH for good

From a checkout. The form to use when you are working on the CLI itself:

git clone https://github.com/tripl-io/tripl.git
uv run --project tripl/cli tripl --version
# tripl 0.1.0

From git, without a checkout. How you get a revision that is not released yet. Both forms below resolve, but neither is exercised by CI:

uvx --from 'git+https://github.com/tripl-io/tripl.git#subdirectory=cli' tripl doctor

pip install 'git+https://github.com/tripl-io/tripl.git#subdirectory=cli'

note

"Install the CLI" and "tripl install" are different things

This section is about getting the tripl command onto your machine. tripl install is a subcommand of it that provisions a tripl server on a host. You need the first before you can run the second — uvx tripl install ... on the deploy host does both in one step.

Distribution name vs import name

The distribution and the console script are both tripl; the import package is tripl_cli. That is deliberate — the service's own source package is backend/src/tripl/, so a distribution installing an importable tripl would shadow it in any environment holding both.

The service is packaged as a separate distribution, tripl-server, and is never published to an index — it ships as a container image. So tripl on PyPI means this CLI and only this CLI.

Configuration

Two values are needed: the instance URL and an API key. Each is resolved independently, through three layers, highest precedence first:

#	Layer	Instance URL	API key
1	Command-line flag	--url (alias --base-url)	--api-key
2	Environment	TRIPL_BASE_URL	TRIPL_API_KEY
3	Config file	base_url	api_key

Per field, not per source: tripl --url https://staging.example.com doctor with the key still coming from the config file works exactly as you would expect. An empty string counts as absent at every layer, so a Compose-materialised TRIPL_BASE_URL="" falls through to the file instead of shadowing it with nothing.

export TRIPL_BASE_URL=https://tripl.example.com
export TRIPL_API_KEY=tk_r_...
tripl doctor

note

There is no TRIPL_URL

Only TRIPL_BASE_URL is read — the same variable the MCP server uses. TRIPL_URL is detected purely so that, when it is set and TRIPL_BASE_URL is not, the error names the right variable instead of shrugging.

A URL pasted from the browser with /api/v1 already on the end is trimmed rather than doubled, and a bare host with no scheme gets a corrected suggestion in the error.

Config file

Platform	Path
Linux / BSD / macOS	$XDG_CONFIG_HOME/tripl/config.toml, else ~/.config/tripl/config.toml
Windows	%APPDATA%\tripl\config.toml, else the ~/.config fallback

XDG_CONFIG_HOME is honoured on every platform, but only when it is an absolute path. macOS uses ~/.config rather than ~/Library/Application Support because this is a file an operator opens in $EDITOR, the same choice git, gh, aws, kubectl and docker make.

# ~/.config/tripl/config.toml
base_url = "https://tripl.example.com"
api_key  = "tk_r_2f9c..."

Unknown keys and unknown tables are ignored, so an older CLI keeps working against a file written by a newer one. --config PATH overrides discovery entirely: a missing default file is fine, a missing --config path is an error.

Permissions on a file holding a key

On POSIX, a config file that contains an api_key and is readable by other users produces one warning on stderr. Fix it with chmod 600 ~/.config/tripl/config.toml. Passing --api-key on the command line is worse still — it is visible to every user on the box through ps(1) and lands in your shell history. Prefer the environment variable or the config file.

Which key to use

A read-only tk_r_ key is enough for doctor, status, watch, scans list, scans jobs and drifts list, and it should be your default. Those six issue nothing but GET, so a write key buys them nothing and risks everything. A read key is also enough for the events and plan verbs, for tripl check, which posts to a validator that changes nothing, and for tripl codegen and tripl export, which only read the plan.

Six verbs mutate the instance and need a tk_w_ key backed by a user with the editor or owner role: scans run, scans cancel, drifts dismiss, drifts reopen, annotate and docs push. The other docs verbs (ls, cat and pull) only read. Give them a key of their own rather than promoting the one in your cron job — see Write safety.

tripl install and tripl upgrade need no key and no URL at all. They act on a directory and the local Docker daemon, so passing --url or --api-key explicitly is exit 2 rather than a silently ignored flag. An ambient TRIPL_BASE_URL exported for tripl doctor does not trip that — only a flag you typed does.

Create keys in the app at Settings → API keys (see API keys & governance). The role behind the key still matters for two things:

• Owner role — data_source.last_test_message is redacted for anyone below owner, so the text of a failed connection probe is only visible to an owner's key. doctor says so explicitly rather than reporting "no message".
• Project-bound keys — a key fenced to one project cannot list projects at all. Pass --project <slug>; see below.

tripl doctor

usage: tripl doctor [-h] [--url URL] [--api-key KEY] [--config PATH]
                    [--project SLUG] [--include-demo] [--json] [--strict]
                    [--timeout SECONDS] [--max-event-types N]

Flag	Meaning
--project SLUG	Check only this project. Repeatable. Required for a project-scoped key.
--include-demo	Also check demo projects, which are excluded by default.
--json	One JSON document on stdout, every human line on stderr.
--strict	Exit 3 on warnings too — never on skipped checks.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.
--max-event-types N	Event-type budget for the drift scan, default 200, range 1–10000.

A healthy instance:

tripl doctor - https://tripl.example.com (from $TRIPL_BASE_URL)

PASS  connectivity  Reached https://tripl.example.com (from $TRIPL_BASE_URL); the API and its database are up.
PASS  auth          The API key authenticates as an instance-wide key (role: owner).
PASS  projects      1 project selected.
PASS  data_sources  1 data source(s) referenced by the selected scan configs; none reports a failed probe.
PASS  scans         1 scheduled scan configs are collecting on time.
PASS  drifts        1 event type(s) examined; no untriaged schema drift.

6 checks: 6 pass. No problems found.

        Data source 'warehouse-prod' (used by scan config 'prod events', 'checkout funnel') last failed its connection test at 2026-07-29T19:08:09Z: 'FATAL: password authentication failed for user "tripl"'.
FAIL  scans         1 of 2 scheduled scan configs is not collecting.

        Scan config 'prod events' (1h) has failed 5 consecutive scheduled runs since 2026-07-31T14:08:09Z. Last error: 'Scan failed due to an internal error.' - that is the backend's generic fallback, not the real cause, so the cause is in the worker log for job job-0.
      - warn: scan_backoff_active [prod] 'prod events'
        The scheduler has deliberately deferred the next attempt to not before 2026-07-31T22:08:09Z (about 4h after the last failure): 3 or more consecutive failures trigger a backoff, so the worker is not stuck.

        Project 'prod' has 1 untriaged schema drifts (oldest detected 2026-07-28T19:08:09Z): app.screen_view.cart_value (type_changed)

6 checks: 3 pass, 1 warn, 2 fail. Exit 3.
Re-run with --json for the machine-readable form of every finding.

Output is ASCII only and byte-identical whether stdout is a terminal or a pipe — no colour, no spinners, no cursor control. tripl doctor | tee incident.log and what you saw on screen are the same artifact, and the log you paste into a ticket carries no escape codes.

The six checks always run in this order and exactly once each; per-project results are findings inside a check, never repeated checks. SKIP means "I could not look", which is never the same thing as a pass — a run where nothing reached a verdict is reported as fail, not as "0 failures".

1. connectivity — instance reachability

Unauthenticated GET /health at the instance root (not under /api/v1). This is the only probe that carries no Authorization header, deliberately: it separates "is the instance up and is its database reachable" from "is your key good", two questions a 401 on an authenticated probe cannot tell apart.

If this check fails, every other check is skipped and the run ends. That is what bounds a dead-host run to roughly one timeout instead of one per endpoint.

Finding	What it means	What to do
instance_unreachable	DNS, TLS, connection refused or timeout.	Check the URL the header printed and where it came from — base_url_source names --url, $TRIPL_BASE_URL or the config file path. Then check the app container and whatever proxy fronts it: Runbook → Health checks.
instance_database_unreachable	/health answered 503 {"status":"error","component":"database"}. The API is up; PostgreSQL is not.	This is a stack problem, not a tripl problem. See Troubleshooting → PostgreSQL. Almost every API request will fail until it is back.
instance_not_tripl	Something answered, but not the way a tripl instance does.	The URL points at a proxy, a load-balancer error page, or the wrong host. Compare with curl -fsS "$TRIPL_BASE_URL/health".

2. auth — API key

GET /auth/me. A 200 means the key is instance-wide and reports the backing user's role; a 403 is a pass, because a project-scoped key is refused on every route without a {slug} path parameter by design. Only the role is printed — never an email, never a key prefix — because doctor output gets pasted into tickets.

Finding	What it means	What to do
api_key_invalid	401. The key is wrong, revoked, or expired.	The message names where the key came from. Mint a new tk_r_ key at Settings → API keys; note that keys can carry an expiry.
auth_unexpected_status	Any other non-200.	Usually a proxy in front of the API rewriting the response. Inspect with curl -i -H "Authorization: Bearer $TRIPL_API_KEY" "$TRIPL_BASE_URL/api/v1/auth/me".

3. projects — project selection and provisioning

Resolves which projects the rest of the run judges. Without --project, the instance listing is used and demo projects are excluded — their runtime ticks and collection cooldown are noise in exactly the checks that matter. The exclusion is always printed, never silent.

Finding	What it means	What to do
project_selector_required (fail)	The key is project-scoped, so doctor cannot discover the slug.	Re-run with --project <slug>. See below.
project_list_forbidden (fail)	GET /projects returned 403 for a key that is not project-scoped.	The backing user's role is insufficient. Use a key owned by a user with access, or name the project with --project.
project_not_found (fail)	A slug passed to --project does not exist.	Check the spelling — it is the URL slug, not the display name.
project_not_authorized (fail)	The key is fenced to a different project.	Use the right key, or the right slug.
no_projects_selected (warn)	The instance has no non-demo projects.	Nothing is broken. Add --include-demo to check the demo workspace, or --project.
project_generation_failed (fail)	Provisioning of a project did not finish. generation_error carries the reason.	The project's data is incomplete and every downstream check about it is unreliable. Re-create it, or see Demo workspace if it is a demo.
project_generating (warn)	Provisioning is still in progress.	Wait and re-run. Counts reported for it are partial.

4. data_sources — warehouse connection probes

Judges only the data sources that a selected project's scan configs actually reference; an unused source failing its probe is not this run's business.

A green connection probe is not evidence of health

last_test_at is written only on an explicit connection test or on a create/update — nothing refreshes it in the background. A source that last tested OK a month ago and has been rejecting the worker's credentials since Tuesday still reports success. That is what data_source_probe_stale exists to say.

Finding	What it means	What to do
data_source_probe_failed (fail)	The last connection test on a referenced source failed.	Start here — it explains the scan failures below it. evidence.last_test_message carries the warehouse's own error. If message_redacted is true, re-run with an owner-role key to see the text. Then see Troubleshooting → A scan run fails.
data_source_probe_stale (warn)	The source last tested OK, but that test predates the moment its scan config started failing.	Do not trust the green. Press Re-test connection on that data source in the app and read the fresh result. evidence.streak_started_at is when the failures began.

5. scans — scheduled metrics collection

The centre of gravity of the whole command, and the check the incident needed. For every scan config that has a collection interval, doctor reads the newest 200 jobs — the API's maximum — and counts the run of consecutive failed dispatcher jobs at the head of the history.

That is deliberately not the 40-row window the dispatcher itself walks. The scheduler only needs the backoff delay, which stops growing at six consecutive failures, so 40 rows are ample for it. doctor answers a different question — how long has this been broken — and at 40 rows a 15m config failing for four days would report 40 failures since this morning instead of 384 since Monday. When every job in the window is a failure the run started even earlier, so the finding says "at least N, at least since T" and sets evidence.consecutive_failures_truncated.

Dispatcher jobs are identified positively, by result_summary.mode == "metrics_collection". Manual catalog scans, metrics replays, event-group applies and demo runtime ticks share the same job table and are neither counted as failures nor treated as the success that ends a streak — so pressing Run now in the app can neither trigger the backoff nor clear it.

Finding	What it means	What to do
scan_config_not_dispatchable (fail)	The config has an interval but no time column, so the scheduler's query never selects it. It is not failing; it is invisible. The app shows the same config with a Needs a time column badge on its row in Govern → Scans.	Open the scan's configuration in the app and set a time column. Nothing will ever collect until you do.
scan_config_failing (fail)	N consecutive scheduled runs failed.	See the walkthrough below.
scan_backoff_active (warn)	The scheduler has deliberately deferred the next attempt.	Nothing. This is expected behaviour — see The retry backoff is not a hang.
scan_watermark_stale (warn)	Collection is succeeding, but the last run only wrote data through evidence.time_to, more than three intervals behind now. Not raised for a demo project, whose watermark freezes while the demo is paused.	The query works and the source table is producing no rows in the scan window. Check the upstream pipeline that fills that table, and the scan's filters. This is the shape of "events frozen with no error".
scan_history_window_full (warn)	Every job in the fetched history window is a manual run, a replay or a demo tick, so whether scheduled collection runs at all could not be determined.	Not a fault by itself. Check the config's job history in the app, or trigger a scheduled collection and re-run.
scan_never_collected (fail)	The config is older than two intervals and no scheduled job has ever run for it. Not raised for a demo project, for the same reason as scan_not_dispatched.	The beat scheduler is probably not running: docker compose logs --tail=50 celery-beat. See Runbook → Health checks.
scan_not_dispatched (fail)	Not failing, but nothing has been dispatched in over three intervals. Never raised for a demo project: the scheduler throttles demos and stops collecting a demo entirely while nobody opens it, so its silence is expected.	Same suspects as above — beat, the broker, or a worker that never picks the task up. See Troubleshooting → RabbitMQ.
scan_interval_unknown (warn)	The backend reports an interval this CLI does not know.	Upgrade the CLI. Staleness and backoff for that config could not be judged, and doctor says so rather than judging with a wrong denominator. Whether it is failing needs no interval, so that is still reported alongside.

Suppression is intentional: a failing config is trivially also "not recently dispatched", so scan_not_dispatched is not raised alongside scan_config_failing. One root cause, one finding.

What to do about scan_config_failing

The evidence is designed to be worked top to bottom:

1. last_error_is_generic: true — the message is the backend's own catch-all, "Scan failed due to an internal error.", which is what any uncurated exception collapses to. Do not quote it as the cause; that is the wall the original incident hit for four days. The real traceback is in the worker log for the job named by last_failed_job_id:

   docker compose logs celery-worker | grep -F '<last_failed_job_id>'

   When last_error_is_generic is false, the text is the curated cause and can be read at face value.

2. data_source_id — cross-reference the data_sources check above. A data_source_probe_failed finding on the same id is your answer, and the scan failure is a symptom.

3. last_success_at and consecutive_failures — when it last worked, and how long it has been broken. If last_success_at is null, it never worked and the config itself is probably wrong.

4. Only after those: open the scan in the app and re-run it manually. A manual run neither counts toward the streak nor clears it, so it is a safe probe.

6. drifts — schema drift

One request per event type, bounded by --max-event-types (default 200). The budget is spread evenly across the selected projects rather than spent in project order, so no project is starved to zero reads by a larger one. What the budget could not reach is reported, never silently omitted — and reported per project, so "nothing found here" and "this project was barely looked at" never print the same.

Finding	What it means	What to do
schema_field_deleted_by_accept (warn)	A missing_field drift was accepted, and accepting one deletes the field definition from the event type.	Verify this was intended. The deletion is invisible in every other surface and is the mechanism by which a field silently vanished from a tracking plan. resolved_at and resolved_by (a user id) say when and by whom. Re-add the field if it was a mistake.
schema_drift_open (warn)	Untriaged drifts — status open, or snoozed past its snooze.	Triage them in the app. evidence.examples names up to three; untriaged_count is the real total.
drift_scan_truncated (warn)	This project has more event types than the budget reached. One finding per affected project; evidence.examined and evidence.total are that project's own counts, and a project examined in full raises no finding at all.	Raise --max-event-types, or narrow the run with --project. Until then, treat the named project's drift result as partial.

endpoint_unexpected_status

This code can appear in projects, scans and drifts, and it always means the same thing: a read did not return 200, so the state it reports is unknown — not empty. doctor never treats a non-200 as an empty list. A 404 read as "no drifts" is exactly the class of mistake this command exists to eliminate. evidence.path and evidence.status_code name the call.

The data_sources check is the one exception, and deliberately: a non-200 there becomes a skip with a skip_reason, because a read key that cannot list data sources is a normal, unfixable fact about that key rather than an instance fault. A skip never counts as a pass, so a run in which every check skipped still exits non-zero.

Project-scoped keys

A key bound to a single project is refused on every instance-level route by design. doctor detects that positively and first, off /auth/me, so it can tell you the right thing instead of inferring it from some later 403:

tripl doctor --project prod

tripl doctor - https://tripl.example.com (from $TRIPL_BASE_URL)

PASS  connectivity  Reached https://tripl.example.com (from $TRIPL_BASE_URL); the API and its database are up.
PASS  auth          The API key authenticates and is scoped to a single project, so instance-wide endpoints are refused by design.
PASS  projects      1 project selected.
SKIP  data_sources  GET /data-sources is instance-level and returns 403 for a project-scoped key by design; re-run with an instance-scoped key to see data-source probe results
PASS  scans         1 scheduled scan configs are collecting on time.
PASS  drifts        1 event type(s) examined; no untriaged schema drift.

6 checks: 5 pass, 1 skip. Exit 0.

--strict deliberately does not promote skips: a project-scoped key would otherwise fail every strict run forever, for a reason the operator cannot fix.

tripl status, tripl watch, tripl scans list and tripl drifts list also need --project with such a key. None of them has a verdict contract, so they simply fail with the API's own 403 message — extended with the hint "If this key is scoped to a single project, that 403 is expected" and the flag to type. Pass --project.

The commands that act on one object — scans jobs, scans run, scans cancel, drifts dismiss, drifts reopen — require --project exactly once from everybody, project-scoped key or not, so they never reach the instance listing and never produce that 403.

Request cost

A healthy one-project instance costs 8 requests: /health, /auth/me, /projects, /data-sources, then per project /scans and /event-types, then one /jobs call per dispatchable scan config and one /drifts call per event type. At most 6 requests are in flight at once — a diagnostic that saturates the instance it is diagnosing reports on the load it created.

The retry backoff is not a hang

This deserves its own section because mistaking it for a stuck worker cost a real investigation.

After 3 consecutive failed scheduled runs, the dispatcher stops retrying at the config's normal cadence and starts backing off exponentially: the delay is interval × 2^(streak − 3), floored at one interval and capped by the smaller of 8 intervals and 24 hours. From the outside this looks exactly like a worker that has stopped — no new jobs appear for hours — which is why doctor reports it as a distinct, warn-level finding that says so in words:

      - warn: scan_backoff_active [prod] 'prod events'
        The scheduler has deliberately deferred the next attempt to not before 2026-07-31T22:08:09Z (about 4h after the last failure): 3 or more consecutive failures trigger a backoff, so the worker is not stuck.

How long the deferral is, by interval and streak length:

Consecutive failures	15m	1h	6h	1d	1w
1–2	no wait	no wait	no wait	no wait	no wait
3	15m	1h	6h	24h	7d
4	30m	2h	12h	24h	7d
5	1h	4h	24h	24h	7d
6 and beyond	2h	8h	24h	24h	7d

A 1d or 1w config therefore never backs off past its own cadence — the floor and the ceiling meet.

These numbers are an estimate, and the field says so

The CLI carries its own copy of the scheduler's constants, so the JSON key is deferred_by_seconds_estimate and the printed sentence says "about". The rule that produced the number ships alongside it as evidence.backoff_after, so a reader can always see the arithmetic. Do not build an alert threshold on the exact value.

What to do: nothing about the backoff itself. Fix the cause named by scan_config_failing; the first successful run clears the streak and the config returns to its normal cadence immediately.

tripl status

usage: tripl status [-h] [--url URL] [--api-key KEY] [--config PATH]
                    [--project SLUG] [--include-demo] [--json] [--days N]
                    [--timeout SECONDS]

A snapshot, not a verdict. It always exits 0 when it completed, however bad the numbers are — a daily digest that returns non-zero is a cron job somebody disables. Use tripl doctor when you want an exit contract.

  monitors   1 firing
  coverage   91.4% over 7 days (388/425 matched)

--days N (default 7, max 180) sets the reconciliation coverage window. Demo projects are excluded unless --include-demo is given, exactly as in doctor.

These numbers are the app's numbers

Every count comes from the project summary the backend computes, not from a second calculation in the CLI. signals is the same significant-open-signal count as the app's badge and monitors the same firing count — they agree by construction, not by coincidence. This matters: the "significant" threshold is already defined in two places in this repository, and a third copy in the CLI would be a drift waiting to happen.

Cost is one request for the project listing plus one coverage request per project — 2 requests for a single-project instance, 3 for the two shown above. With --project, the listing is replaced by one read per named slug.

note

status and doctor count failing scans differently

status prints the server-side rollup failing_scan_config_count; doctor derives its own count by walking each config's job history. They normally agree. If they ever disagree in the field, doctor's number is the one with the evidence attached — read the scans findings.

tripl whoami

usage: tripl whoami [-h] [--url URL] [--api-key KEY] [--config PATH] [--json]
                    [--timeout SECONDS]

Answers "whose key is this, and where does it act?" with one read of GET /api/v1/auth/me. Nothing is written.

tripl whoami - https://tripl.example.com (from $TRIPL_BASE_URL)

user:  Deploy bot <deploy@example.com>
key:   write, reaches the whole organization
org:   acme (role: admin)

• user is the account that minted the key. A key acts as that account, with its role, in one organization.
• key is the key's access (read or write) and its reach: the whole organization, or one project for a project-bound key.
• org is the organization the key is bound to, and the account's role there. A key reaches only that organization, whichever others its account belongs to.

A project-bound key cannot read /auth/me at all (every route without a project slug refuses it with 403). whoami reports that as the answer rather than as a failure, and exits 0:

key:   read, bound to one project
user:  unknown (a project-bound key cannot read /auth/me)

Against an instance older than organizations the access is read off the key's tk_r_ / tk_w_ prefix and org is unknown. A rejected key (401) exits 1.

--json prints one document with reach (instance or project), access, user (id, email, name, or null), org, role, is_platform_admin and orgs (the slugs of every organization the account belongs to). Cost: 1 request.

tripl watch

usage: tripl watch [-h] [--url URL] [--api-key KEY] [--config PATH]
                   [--project SLUG] [--include-demo] [--scan NAME_OR_ID]
                   [--interval SECONDS] [--duration SECONDS]
                   [--stall-after SECONDS] [--json] [--timeout SECONDS]

doctor answers "what is broken" at one instant and then exits. watch answers "what is happening right now": it stays attached and prints one line every time something moves — a replay advancing from chunk 4 to chunk 5, a job finishing, a signal opening, an alert delivery failing to page anyone. It is the command for the half hour after the page, when the question is no longer "is something wrong" but "is this scan hung, or just slow?" — the exact question an operator answered by hand over ssh for four days during the 2026-07-28..31 incident.

It reaches no verdict. Whatever it observes, a completed run exits 0 and it never exits 3. A green watch run proves strictly less than a green doctor run — watch only ever saw what fell inside its polls — so building a CI gate on it would be a slower, flakier doctor --strict. Use doctor when you want an exit contract.

It polls. There is no daemon and no subscription.

tripl does have a Server-Sent Events stream, and watch deliberately does not use it. The replay chunk counter — this command's headline — is written straight into the scan job's result_summary by the worker's progress heartbeat, with no realtime event published alongside it, so it is invisible on that bus. The bus also degrades to silence when Redis is absent while the socket still looks healthy. Polling the REST API is more transport for strictly more information.

Flag	Meaning
--project SLUG	Follow only this project. Repeatable. Required for a project-scoped key.
--include-demo	Also follow demo projects, which are excluded by default.
--scan NAME_OR_ID	Follow only these scan configs, matched exactly on name and then on id. Repeatable. Narrows the job lines only.
--interval SECONDS	Seconds between polls, default 10, range 2–3600.
--duration SECONDS	Stop after this many seconds and exit 0, range 1–86400. Default: run until Ctrl-C.
--stall-after SECONDS	Report a running job whose progress has not moved for this long, default 120, range 10–86400.
--json	JSON Lines on stdout, one object per event; every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

--scan never filters signals or deliveries. A metric-scope signal carries no scan config at all, so filtering the whole feed by scan config would make exactly the anomalies an incident is built from disappear.

A session: a replay is already running when you attach, it advances, a signal opens, an alert delivery fails, the replay finishes, and you press Ctrl-C.

The layout is fixed: RFC 3339 timestamp, event token, [project], message, with the message always starting at column 39. Like doctor, output is ASCII only and byte-identical whether stdout is a terminal or a pipe — no colour, no spinner, no redraw, no cursor control. That is not decoration for a follow mode; it is the point. tripl watch | tee incident.log has to produce the artifact you actually saw, and a live-updating dashboard would produce neither. The preamble holds one more invariant worth knowing: no preamble line starts with a timestamp and every stream line does, so

tripl watch | grep -E '^[0-9]{4}-'

is the event stream on its own.

The first screen

A follow mode that only reported transitions it personally observed would tell an operator who started it thirty seconds late that nothing is happening. So the first successful read of every stream seeds the state — and then the preamble prints what that seed found, before a single event line:

• the cadence and the request budget, so the load this command adds to an already-unwell instance is stated rather than guessed at;
• every running and pending job, with its mode and, for a replay, its current chunk, percentage, phase and age. This is the "is it hung?" answer at attach time;
• the open signal count across all scopes, marked (baseline), printed beside the project summary's own significance-filtered count. Two different populations, both labelled — never one silently standing in for the other;
• the count of failed deliveries in the newest 20, also (baseline).

Signals are counted, not listed. A 200-signal incident would bury the stream before it began; tripl status is the command for the list.

Everything in the preamble is therefore already known and is never re-emitted as an event. Subsequent silence means "no new ones", not "nothing wrong".

What counts as new

Each tick builds a fresh snapshot and diffs it against the previous one. There is no growing "everything I have printed" set, so memory is flat over an eight-hour run.

Stream	Identity	Reported when
Jobs	The job id, within the newest 10 jobs of each followed scan config	status, replay_progress_phase, replay_chunks_completed or replay_current_chunk_index changed
Signals	(scan_config_id, scope_type, scope_ref) — the backend's own key	The identity is new, or its bucket, direction or state changed
Deliveries	The delivery id, within the newest 20 failed deliveries	The row is failed and was not already reported as failed

Three consequences are worth stating outright:

• updated_at is deliberately not part of a job's identity of change. The worker's progress heartbeat bumps it even on the ticks where no counter moves. Including it would print a line every heartbeat and, far worse, would make job.stalled unreachable — a heartbeating-but-wedged job would look alive, which is precisely backwards. updated_at still ships in the JSON data.
• A signal's bucket is not part of its identity. If it were, a signal advancing to a later bucket would produce a signal.cleared followed by a signal.opened — a fabricated resolution in the middle of a live incident.
• A job disappearing is not an event. The job list is a window ordered newest first, so a row leaving it is an artifact of the window, not a thing that happened. A signal disappearing is reported, because the signals endpoint returns the complete active set with no window.

A scan config created mid-run is discovered on the slow clock and then seeds silently, exactly like the ones present at startup. A project created mid-run is not picked up — restart watch for that.

Event tokens

event is a stability contract; the message beside it is prose and may be reworded in any release.

Token	Stream	Emitted when
watch.started	meta	Once, right after the first screen. Carries the resolved options and the baseline counts.
watch.stopped	meta	Once, last. data.reason is interrupted, duration_elapsed or authentication_failed.
job.queued	event	A job is pending — newly seen, or moved back into it.
job.started	event	A job is running. Also fires for a job first seen already running.
job.progress	event	A running metrics_replay job's chunk counter or phase moved. The line the incident needed.
job.stalled	event	A metrics_replay job's published progress has not moved for --stall-after seconds.
job.unchanged	event	A job with no progress channel has not changed status for --stall-after seconds — a pending job no worker has picked up, or a long-running metrics_collection.
job.finished	event	completed. For a replay, the message carries the final chunk count.
job.failed	event	failed. Carries error_message, or says there was none.
job.cancelled	event	cancelled.
signal.opened	event	A signal identity that was not in the previous active set.
signal.updated	event	An already-open signal whose bucket, direction or state moved.
signal.cleared	event	A signal left the active set.
delivery.failed	event	An alert delivery is in status failed. Nobody was paged.
poll.degraded	diagnostic	A read did not return 200, or a full window may have hidden rows.
poll.recovered	diagnostic	A stream that had been failing answered again.

A scheduled collection job — result_summary.mode == "metrics_collection" — has no chunk counters, so it produces job.queued / job.started / job.finished / job.failed and never job.progress. That is not a gap in watch: the backend publishes no progress for those jobs, and watch does not invent progress it was not given. job.progress is a metrics_replay line.

tip

signal.cleared says "cleared", not "resolved"

A signal leaving the active set may only mean its freshness window closed. The line claims exactly what was observed and nothing more, and it prints how many signals are still open in that project so a disappearance never reads as an all-clear.

job.stalled is a statement about observation

It says watch has seen no progress since T — never this job is broken. A replay chunk over a large window legitimately takes minutes.

Which is also why there are two tokens rather than one. Only a metrics_replay job publishes a progress counter; a scheduled metrics_collection job and a job still sitting in pending publish nothing that could move short of their status. Reporting those as job.stalled would claim an observation watch was never in a position to make — and, because such a job's state cannot change while it runs, it would fire on every long collection, which is a false alarm with a schedule. So they get job.unchanged, whose message says what was actually seen: still in status pending after 4m of watching (no worker has picked it up). That sentence is the one you want when the queue is not draining, which is the most common way a scan appears to hang.

Both tokens carry the same unchanged_since and unchanged_seconds evidence and share the re-report schedule described next.

The threshold is counted in seconds, not polls, so --interval 60 does not silently turn a 120-second threshold into a two-hour one. A condition that persists re-reports on a power-of-two schedule — at 1x, 2x, 4x, 8x the threshold — which is roughly a dozen lines over four hours instead of one every tick, while still telling you it is still going. Any observed progress restarts the clock, so there is no "unstalled" line to keep track of.

The schedule is easiest to see at a threshold far below the default, which is what produced the three lines below — 30s, then 60s, then 2m, at 1x, 2x and 4x:

tripl watch --stall-after 30

2026-07-31T19:11:11Z  job.stalled      [prod] 'nightly replay' job job-91c2 unchanged for 30s at chunk 5 of 18 (27.8%) collecting; watch has seen no progress since 2026-07-31T19:10:41Z.

2026-07-31T19:12:41Z  job.stalled      [prod] 'nightly replay' job job-91c2 unchanged for 2m at chunk 5 of 18 (27.8%) collecting; watch has seen no progress since 2026-07-31T19:10:41Z.

When a poll fails

The run continues. A follow tool that exits when the thing it follows goes down is exactly backwards — an operator watching an instance through a rolling restart wants watch still there when it comes back, and exiting would truncate a | tee incident.log capture at the worst possible moment.

A failed read does not update its stream's snapshot. Diffing against an empty list would print signal.cleared for every open signal and then reprint them all as signal.opened on recovery — lying twice, during the incident. Holding the last good snapshot turns an outage into a reporting delay: the next good poll fires every transition that happened while watch was blind, late but complete.

2026-07-31T19:11:11Z  poll.degraded    [prod] signals read failed: HTTP 500 on /projects/{slug}/anomalies/signals. Signal lines are suspended until it recovers - no signal lines does NOT mean no signals.
2026-07-31T19:11:21Z  poll.degraded    [prod] signals read failed: HTTP 500 on /projects/{slug}/anomalies/signals. Signal lines are suspended until it recovers - no signal lines does NOT mean no signals.
2026-07-31T19:11:41Z  poll.recovered   [prod] signals read recovered after 30s (3 failed polls); 1 events reported from the gap.

Note the arithmetic: three polls failed, two lines were printed. poll.degraded follows the same power-of-two schedule as job.stalled — the 1st, 2nd, 4th, 8th consecutive failure of a stream gets a line and the rest are quiet. poll.recovered is never throttled, and it carries the number that matters: how many events came out of the gap, which is how you learn that a quiet stretch was watch being blind rather than the instance being calm.

Two more shapes of degradation:

• A 403 is only ever a line. It is legitimately per-project and per-role, and the other projects are still reporting usefully. If every project 403s you get a wall of lines naming the 403, and you can stop the run.
• A full window in which every row is new also raises poll.degraded, with window_full: true. It means older rows may have been pushed out between polls; lower --interval or narrow the run. Merely hitting the limit is not reported — a healthy config with ten jobs of history does that every poll and it means nothing.

A 401 is the one failure that ends the run. The key is gone and waiting cannot fix it, and continuing would hammer an auth path that is logged and rate limited. watch prints the poll.degraded line, then watch.stopped with reason: "authentication_failed", then the usual tripl: ... error, and exits 1.

The run can also be refused before it prints anything: watch needs the scan listing to know what to follow, so if GET /projects/{slug}/scans fails during startup the command fails there rather than half way through a feed.

A degraded slow stream is retried at the fast interval

Signals, deliveries and the scan listing are normally polled at most every 30 seconds. That clock only advances on a successful read, so while one of them is failing it is retried on every tick — three times the usual rate against an instance that is, by assumption, already unwell. Raise --interval if you are watching an instance through a sustained outage.

Request cost

Per tick: one request per followed scan config, asking for the newest 10 jobs. That window is deliberately far smaller than doctor's 200 — doctor asks how long has this been broken and needs history, watch asks what appeared since the last poll and needs recency, and 20x the payload on a loop that repeats every ten seconds is a load problem this repository has already paid for once.

On a slow tick — at most once every 30 seconds per project — three more requests are added per project: the scan listing, the open signals (expanded=true, so event-scope anomalies are not dropped), and the newest 20 failed alert deliveries. The 30 seconds is not invented: the backend caches the unfiltered active-signals query for exactly that long, so polling faster is provably wasted work.

At most 6 requests are in flight at once, and only one tick is ever in flight: the interval is measured after the previous tick finished, never on a fixed wall clock and never with catch-up. An instance that answers slowly is therefore automatically polled less, and a 40-second stall can never be followed by a burst of queued ticks.

watch refuses to start above 24 selected scan configs rather than truncating, and says so with the flags to narrow it. A one-shot command can report what its budget could not reach; a command that repeats would have to reprint that warning every tick, or print it once at the top where it scrolls away and leaves you reading a feed silently missing the config the incident is in.

A config deleted mid-run keeps being polled

It produces poll.degraded lines with a 404, on the power-of-two schedule, until you restart. This is deliberate: silently dropping a target is the exact failure mode watch exists to avoid.

Write safety

doctor, status and watch only ever read. Six verbs do not, and this is the one table to read before you run any of them:

Command	What it changes on the instance	Key	Backing role	Asks first
tripl scans run	Queues a scan job, which executes the config's stored SQL against your warehouse.	tk_w_	editor or owner	No
tripl scans cancel	Stops a pending or running job. A running job is not killed: it stops at its next checkpoint — a metrics run at the next chunk boundary, keeping the metrics it already wrote; a catalog run or an event-group apply immediately before its write commits, so stopped there it writes nothing at all. Stopped after that commit, the work it had already made durable stays. Either way a stopped job stays cancelled.	tk_w_	editor or owner	Yes
tripl drifts dismiss	Moves one schema drift to false_positive or snoozed, which takes it out of doctor's untriaged count.	tk_w_	editor or owner	Yes
tripl drifts reopen	Moves one schema drift back to open, and discards its resolution note and resolver.	tk_w_	editor or owner	Yes
tripl annotate	Adds one chart annotation with source api. The same label posted again with source api within 24 hours is de-duplicated: nothing new is created.	tk_w_	editor or owner	No
tripl docs push	Imports a folder of .md files into one scope of the docs catalog: creates and updates notes, and with --mirror deletes every note of the scope the folder does not carry. On a terminal it posts a dry_run=true preview first, which changes nothing.	tk_w_	editor or owner; organization needs a key not bound to one project, and --mirror on organization is refused to every key	Yes

Everything else on this page — doctor, status, watch, scans list, scans jobs, drifts list, docs ls, docs cat, docs pull — is GET-only and needs nothing but tk_r_.

The CLI does not judge your key

There is no local tk_r_ / tk_w_ check. The prefix is derived server-side from the scope's first letter and says nothing at all about the backing user's role, so a client-side gate would be a fourth copy of a backend rule and still wrong for a tk_w_ key held by a viewer. The request goes out and the API's own 403 is printed, naming all three possibilities at once:

tripl: Forbidden (403): the API key lacks the required scope (tk_r_ keys cannot write), is scoped to a different project, or the backing user role is insufficient. API detail: API key has read-only scope

Read API detail: — it is the server's own sentence and it says which of the three actually applied.

--dry-run is on all six

It resolves everything a real invocation would resolve — including turning a <scan> name into a config id, which is where a typo becomes exit 2 — prints the exact request, and sends nothing:

tripl scans run 'prod events' --project prod --dry-run

tripl scans run - https://tripl.example.com (from $TRIPL_BASE_URL)

dry run: would send POST /projects/prod/scans/scan-1/run with body None
Nothing was sent.

The printed request is method, path, params and body, and nothing else — no headers, no Authorization, no API key. A credential that can be printed eventually is, so it is excluded at the one place the request is projected for printing. --dry-run also short-circuits the confirmation prompt, because there is nothing to confirm.

The dry-run body is Python's spelling, not JSON

with body {'action': 'false_positive'} and with body None are the repr of the body, so quotes are single and null is None. Do not paste that into curl. The --json document carries the same body as real JSON — use tripl drifts dismiss ... --dry-run --json | jq .request if you want something a machine can consume.

The confirmation rule

scans cancel, drifts dismiss, drifts reopen and docs push prompt. scans run and annotate do not, and neither has a --yes at all — passing one is exit 2, because a flag that does nothing here is a flag a script author will assume does something on the next command too. The reasoning is that run executes SQL an owner already authored, on a schedule that already runs it, and annotate adds a marker that is cheap to delete from a pipeline that has nobody to ask; cancel throws away work in flight, dismiss hides a finding from doctor, reopen destroys the note that says why the finding was hidden, and docs push overwrites notes, or deletes them under --mirror.

tripl scans cancel 'prod events' job-91c2 --project prod

Cancel job job-91c2 of prod 'prod events'? It stops at the next chunk boundary; metrics already written are kept. [y/N] y
tripl scans cancel - https://tripl.example.com (from $TRIPL_BASE_URL)

prod 'prod events' (scan-1): job job-91c2 is now cancelled.

The question goes to stderr, not stdout — input() would have put prose inside the one document --json promises. Anything but y or yes — including an empty line and end-of-file — aborts with tripl: aborted. Nothing was sent. and exit 1, never 0: a script must never be able to read "the operator said no" as "the mutation happened".

warning

In a pipeline, --yes is mandatory, not optional

When stdin is not a terminal and --yes was not given, scans cancel, drifts dismiss, drifts reopen and docs push refuse: they print the question, name --yes, exit 2 and send nothing.

tripl: Mark drift drift-1 of prod as false_positive? It stops appearing in `tripl doctor`'s untriaged count. Refusing to prompt because stdin is not a terminal. Re-run with --yes to confirm non-interactively. Nothing was sent.

Both halves of that rule are deliberate. Prompting would hang the cron job that invoked it, forever; proceeding silently would make a piped invocation more dangerous than a typed one, and would make --yes meaningless.

A 201 is not proof the scan started

scans run reads the job it gets back. The backend catches a broker failure inside the trigger and still answers 201, with the job already in status failed and an error_message on it — so a script that checked only the status code would report a scan that never started as started. The CLI prints the message and exits 1:

tripl: the job was created but is already failed: broker unavailable

What is deliberately not here

Two operations exist in the REST API and will not be added to this CLI.

• A bounded metrics replay. POST /projects/{slug}/scans/{scan_id}/metrics/replay is guarded by get_owner_user, which rejects any request carrying an API key scope — read or write, editor or owner. It is owner-session-only, so a Bearer-token client cannot reach it at all and a tripl scans replay would 403 every time. scans cancel ships in its place. Whether an owner-role tk_w_ key should be let through is an open backend question.

• Accepting a schema drift. On a missing_field drift, accepting deletes the field definition from the event type — the exact damage doctor's schema_field_deleted_by_accept finding exists to report. The tool that reports that damage must not be the easiest way to cause it, so accepting stays in the tripl app. dismiss sends false_positive or snooze, reopen sends reopen, and no flag on either reaches accept.

  The API refuses one slice of that damage on its own: accepting a missing_field drift for a column a scan config's event name format builds event names from answers 409, because the delete would fail every subsequent collection. It carries a force override for the case where that guard over-fires, and force has no flag here either — it is reachable only from a request body you write yourself, which is the point. See Schema drift.

tripl scans

doctor tells you a scan config is failing and watch follows one while it runs. tripl scans is what you type in between: which configs exist and would the scheduler ever pick them up, what has this one been doing, start it now, stop the one that is stuck.

usage: tripl scans [-h] [--url URL] [--api-key KEY] [--config PATH] <verb> ...

Four verbs: list, jobs, run, cancel. A bare tripl scans with no verb prints this group's help on stderr and exits 2 — the same rule a bare tripl follows, for the same reason: a script that invoked a group with no verb has a bug, and exiting 0 would let it look successful.

note

Why scans list and not list-scans

A command acting on the instance as a whole is one word (doctor, status, watch); a command acting on a class of objects is <plural-noun> <verb>. The flat spelling was rejected because it adds a top-level entry per verb and has no answer for the sixth.

tripl scans list

usage: tripl scans list [-h] [--url URL] [--api-key KEY] [--config PATH]

Flag	Meaning
--project SLUG	List only this project. Repeatable. Required for a project-scoped key.
--include-demo	Also list demo projects, which are excluded by default.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

That last one is the reason the command is worth having: the scheduler's query needs an interval and a time column, both set, so not scheduled (no time column) names a config that is not failing — it is invisible, and nothing will ever collect for it. That is the same condition doctor reports as scan_config_not_dispatchable, evaluated by the predicate doctor itself uses to decide whose job history is even worth reading — and the same one the web UI badges as Needs a time column.

base_query and roughly twenty tuning knobs are omitted. Free-text SQL runs to kilobytes and answers no operational question; read the full configuration in the app.

A project whose listing failed still counts in the footer

A failed read is a printed unavailable line, an errors[] entry in the JSON, and exit 1 — never a shorter table at exit 0.

mobile (Mobile)
  /projects/mobile/scans: unavailable (Forbidden (403): the API key lacks the required scope (tk_r_ keys cannot write), is scoped to a different project, or the backing user role is insufficient. API detail: Not authorized for project)

4 scan configs in 2 projects.
1 read failed; the list above is incomplete.

Note what the footer says: 4 configs in 2 projects, because the project that 403'd is still one of the two selected. The count is of what arrived, the denominator is of what was asked for, and the line underneath is the one that tells you they are not the same number — and it counts the failures, so one 403 out of six projects reads differently from six. It is the same sentence drifts list prints for the same condition, deliberately: one grep over an incident log finds both.

Cost: one request for the project listing (or one per named --project slug), plus one per project.

tripl scans jobs

usage: tripl scans jobs [-h] [--url URL] [--api-key KEY] [--config PATH]
                        [--project SLUG] [--limit N] [--json]
                        [--timeout SECONDS]
                        <scan>

Flag	Meaning
<scan>	Scan config name or id, matched exactly — name first, then id.
--project SLUG	Required, exactly once.
--limit N	How many jobs to ask for, 1–200, default 50.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

This is the command that hands you a job id for tripl scans cancel.

tripl scans jobs 'prod events' --project prod --limit 3

tripl scans jobs - https://tripl.example.com (from $TRIPL_BASE_URL)

prod 'prod events' (scan-1), newest 3 jobs requested:
  job-91c2  running    created 2026-07-31T19:08:41Z  finished -
  job-70ab  failed     created 2026-07-31T18:08:41Z  finished 2026-07-31T18:09:02Z  Scan failed due to an internal error.
  job-4d19  completed  created 2026-07-31T17:08:41Z  finished 2026-07-31T17:08:58Z

3 jobs.

The header says requested, not returned: the footer counts what came back, and the two differ whenever the config has less history than you asked for.

The default of 50 is the API's own default, deliberately not doctor's 200. scans jobs answers what has this config been doing lately, which a screenful covers; doctor asks how long has this been broken and needs the maximum. It is one flag away — --limit 200.

Cost: two requests — the project's scan listing, to resolve <scan>, then the job history.

note

<scan> is matched exactly, and refuses to guess

Exact on the name first, then on the id. Never a substring, never case-insensitive: a scans run that triggered the wrong SQL because two names share a prefix is worse than one that refuses to start. A selector matching nothing exits 2 and lists the candidates; a name shared by two configs exits 2 and names both ids so you can pass one. It is literally watch's --scan matcher, so tripl scans run 'prod events' and tripl watch --scan 'prod events' cannot mean different configs.

tripl scans run

usage: tripl scans run [-h] [--url URL] [--api-key KEY] [--config PATH]
                       [--project SLUG] [--dry-run] [--json]
                       [--timeout SECONDS]
                       <scan>

Flag	Meaning
<scan>	Scan config name or id, matched exactly.
--project SLUG	Required, exactly once.
--dry-run	Resolve everything, print the request, send nothing.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Write. Needs a tk_w_ key backed by an editor or owner. Does not prompt, and has no --yes.

tripl scans run 'prod events' --project prod

tripl scans run - https://tripl.example.com (from $TRIPL_BASE_URL)

prod 'prod events' (scan-1): started job job-91c2 (pending).
Follow it with: tripl watch --project prod --scan 'prod events'

The second line is the point of the pairing: run starts the job and returns immediately, and watch is the command that tells you whether it is progressing or wedged.

This is the same route the app's Run now button posts to, so the rule described under scans applies unchanged: doctor identifies dispatcher jobs positively, so a manual run neither counts toward the consecutive-failure streak nor clears it. It is a safe probe while you are debugging a failing config.

Cost: two requests, or one with --dry-run.

--project SLUG	Required, exactly once.
--dry-run	Resolve everything, print the request, send nothing. Never prompts.
--yes	Skip the confirmation. Required when stdin is not a terminal.

tripl scans cancel - https://tripl.example.com (from $TRIPL_BASE_URL)

prod 'prod events' (scan-1): job job-91c2 is now cancelled.

A job that is neither pending nor running answers 409, which surfaces as exit 1 with the API's own sentence:

tripl: tripl API rejected the request (409): Scan job is not active (status: completed)

Cost: two requests, or one with --dry-run.

tripl drifts

Schema drift is the gap between the tracking plan and what the warehouse actually carries. doctor reports it as a count and up to three examples; tripl drifts list is the full list, and tripl drifts dismiss is how you take one row out of the untriaged pile without opening the app.

usage: tripl drifts [-h] [--url URL] [--api-key KEY] [--config PATH] <verb> ...

Three verbs: list, dismiss and reopen. A bare tripl drifts prints this group's help on stderr and exits 2.

tripl drifts list

usage: tripl drifts list [-h] [--url URL] [--api-key KEY] [--config PATH]
                         [--project SLUG] [--include-demo] [--status STATUS]
                         [--max-event-types N] [--json] [--timeout SECONDS]

Flag	Meaning
--project SLUG	List only this project. Repeatable. Required for a project-scoped key.
--include-demo	Also list demo projects, which are excluded by default.
--status STATUS	open, accepted, snoozed, false_positive, untriaged or all. Default untriaged.
--max-event-types N	Read budget for the fan-out, default 200, range 1–10000.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

tripl drifts list - https://tripl.example.com (from $TRIPL_BASE_URL)

prod (Prod)
  drift-1  app.screen_view.cart_value  type_changed  open  detected 2026-07-28T04:10:00Z
  drift-3  app.purchase.coupon_code    new_field     open  detected 2026-07-30T22:41:00Z

mobile (Mobile)
  (no drifts)

2 drifts in 2 projects, 2 untriaged.

The columns are the drift id, <event type>.<field>, the drift type, the status, and the timestamp that matters for that status — when a snooze lapses for a snoozed row, when it was detected for everything else. The date an operator acts on is the one that gets printed.

There is no project-level drift endpoint

The API answers drifts per event type, so "this project's drifts" is a fan-out — one request each — which is why there is a budget at all, and why "could not read one event type" is a case that has to exist. It is reported as a line, an errors[] entry and exit 1, never as a shorter list at exit 0:

prod (Prod)
  /projects/prod/event-types: unavailable (Forbidden (403): the API key lacks the required scope)

0 drifts in 1 project, 0 untriaged.
1 read failed; the list above is incomplete.

0 drifts and 1 read failed on the same screen is the whole design. Never read the first line without the second.

--max-event-types is spent round-robin across the selected projects, not in project order, so one large project cannot consume the whole budget and leave another at zero reads with nothing said about it. What the budget did not reach is reported per project:

  183 of 240 event types examined; raise --max-event-types to look at the rest.

This is the same planner doctor's drifts check uses, from the same function — two implementations of a budgeted fan-out is how "we did not look there" starts printing as "nothing there".

note

--status is filtered by this CLI, not by the API

The drifts endpoint has no status parameter, so every status is fetched and the filter is applied locally. Two consequences. The request cost does not change with --status. And untriaged is a rule, not a status: open, or snoozed with a snoozed_until that has already passed. A snooze that has lapsed is untriaged again, which is exactly what makes a snooze safe.

The footer's N untriaged counts the rows on screen. Under the default it therefore always equals the drift count; under --status false_positive it is always 0. It tells you something only under --status all.

Cost: one request for the project listing (or one per named --project slug), one per project for its event types, then one per event type actually examined.

tripl drifts dismiss

usage: tripl drifts dismiss [-h] [--url URL] [--api-key KEY] [--config PATH]
                            [--project SLUG] [--snooze-until TS] [--note TEXT]
                            [--dry-run] [--yes] [--json] [--timeout SECONDS]
                            <drift-id>

Flag	Meaning
<drift-id>	The drift to dismiss. Take it from the first column of drifts list.
--project SLUG	Required, exactly once — the action route carries a slug that a drift id cannot supply.
--snooze-until TS	RFC 3339. Its presence selects snooze; its absence selects false_positive.
--note TEXT	Resolution note stored with the drift. The server caps it at 2000 characters. Replaces the stored note; omitting it leaves the stored note untouched — see below.
--dry-run	Resolve everything, print the request, send nothing. Never prompts.
--yes	Skip the confirmation. Required when stdin is not a terminal.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Write. Needs a tk_w_ key backed by an editor or owner. Prompts.

tripl drifts dismiss drift-1 --project prod --yes

tripl drifts dismiss - https://tripl.example.com (from $TRIPL_BASE_URL)

prod: drift drift-1 (cart_value, type_changed) is now false_positive.

tripl drifts dismiss drift-1 --project prod \
  --snooze-until 2026-08-04T00:00:00Z \
  --note 'waiting on the mobile release' --yes

tripl drifts dismiss - https://tripl.example.com (from $TRIPL_BASE_URL)

prod: drift drift-1 (cart_value, type_changed) is now snoozed.

There is no --action flag, and that is the safety design rather than an omission: the only two actions reachable are false_positive and snooze, and which one you get is decided by whether you passed a timestamp. This command never sends accept — see what is deliberately not here. Undoing a dismissal is tripl drifts reopen, a verb of its own, because it moves the drift the other way and destroys something on the way.

note

--note overwrites; omitting it keeps the note already on the drift

The action route writes resolution_note only when the request carries a note, so a drift dismissed last week with --note 'waiting on the mobile release' and snoozed again today without --note keeps last week's sentence. This has not always been true: the route used to assign the note on every call, so an action without one erased the reason. A runbook that tells you to re-pass --note on every dismiss to avoid losing it is describing the old defect and no longer buys anything.

What remains true is that --note TEXT replaces whatever was stored — there is no append, and the drift keeps exactly one note. Read the current one out of tripl drifts list --json before you overwrite a note you did not write; resolution_note is carried there verbatim. The only way to blank a note from here is --note '', which stores an empty note rather than removing it.

This CLI omits note from the request body entirely rather than sending null — --dry-run prints the exact body — so the paragraph above holds however a raw client's explicit null is read. The one action that clears a note unconditionally is reopen, and it is not reachable from this command — it is a verb of its own, which is why it takes no --note.

warning

A naive --snooze-until is read as UTC, not as your local time

--snooze-until '2026-08-04T00:00:00' means midnight UTC. A snooze silently shifted by your machine's offset is a drift that reappears at the wrong hour, so the CLI picks the unambiguous reading and the API stores an aware datetime either way. Pass the offset explicitly (...T00:00:00Z, ...+02:00) if you care. A value that is not RFC 3339 fails at parse time, exit 2, before a socket opens.

A --snooze-until in the past is accepted by the server and the CLI will report is now snoozed — but a lapsed snooze counts as untriaged, so the drift is back in drifts list and in doctor's count immediately. Check the timestamp.

Cost: one request, or zero with --dry-run — the drift id and the slug come straight from your arguments, so there is nothing to resolve first. The corollary is that a wrong <drift-id> is discovered by the server, as a 404 and exit 1, not by the CLI.

tripl drifts reopen

usage: tripl drifts reopen [-h] [--url URL] [--api-key KEY] [--config PATH]
                           [--project SLUG] [--dry-run] [--yes] [--json]

                           <drift-id>

Flag	Meaning
<drift-id>	The drift to reopen. Take it from the first column of drifts list.
--project SLUG	Required, exactly once — the action route carries a slug that a drift id cannot supply.
--dry-run	Resolve everything, print the request, send nothing. Never prompts.
--yes	Skip the confirmation. Required when stdin is not a terminal.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Write. Needs a tk_w_ key backed by an editor or owner. Prompts.

The undo for a dismissal that turned out to be wrong: the drift goes back to open, its snooze is cleared, and it counts as untriaged in tripl doctor again.

tripl drifts reopen drift-1 --project prod --yes

tripl drifts reopen - https://tripl.example.com (from $TRIPL_BASE_URL)

prod: drift drift-1 (cart_value, type_changed) is now open.

warning

Reopening destroys the resolution note and the resolver

This is not the harmless direction. The action route clears resolution_note, resolved_by and resolved_at for reopen — so who dismissed this drift and why are gone the moment the request lands, and dismissing it again does not bring them back. Nothing in the API restores them.

If the sentence matters, read it out of tripl drifts list --json first; resolution_note is carried there verbatim. That is also why there is no --note here: the route clears the note before it looks at the request's, so a flag would take a sentence, report success, and store nothing.

There is no --snooze-until either — reopening clears the snooze rather than setting one. To move a snooze, dismiss again with the new timestamp; that is one request instead of two and never blanks the note in between.

Cost: one request, or zero with --dry-run.

tripl events

doctor, status, scans and drifts all answer questions about the machinery. tripl events and tripl plan answer questions about the content: what is in the catalog, what shape is it declared to have, and what changed on a branch.

usage: tripl events [-h] [--url URL] [--api-key KEY] [--config PATH] <verb> ...

Two verbs: list and show. A bare tripl events prints this group's help on stderr and exits 2.

Both take exactly one --project. Every route here is per project and there is no instance-wide form, so a repeated --project would be a fan-out this command does not do — unlike scans list and drifts list, where repeating it widens a real fan-out.

Read only, and staying that way

POST /projects/{slug}/events and PATCH /projects/{slug}/events/{event_id} exist, and the shared request layer builds both — the MCP server's create_event and update_event tools use them. There is no tripl events create.

A catalog write has to land on a plan branch: the MCP makes branch_id required on both write tools precisely so an agent's draft never lands on the live main plan by accident. Reproducing that gate from a shell means resolving a branch, refusing main, prompting, and then reading the server's canonical-name warnings back to you — because when a scan naming rule governs the event type, the server derives the name from field values and may ignore the one you sent. That is a command surface of its own. Shipping the easy half first would leave the CLI with a write that is easier to get wrong than the agent's.

Until then: edit in the tripl app, or through the MCP server.

tripl events list

usage: tripl events list [-h] [--url URL] [--api-key KEY] [--config PATH]
                         [--project SLUG] [--branch REF] [--search TEXT]
                         [--status STATUS] [--tag TAG] [--field-value TEXT]

                         [--reviewed | --unreviewed]
                         [--offset N] [--limit N] [--order-by ORDER] [--json]
                         [--timeout SECONDS]

Flag	Meaning
--project SLUG	Required, exactly once.
--branch REF	Read a plan branch instead of the live main plan. Name or id, matched exactly.
--search TEXT	Substring match over name and description.
--status STATUS	Lifecycle state. Repeatable, and the API keeps an event matching any of them.
--tag TAG	Exact tag match.
--field-value TEXT	Substring match on any field value — a screen name, typically. Case-insensitive.
--meta-value TEXT	Substring match on any meta value — a ticket key, typically. Case-insensitive, so --meta-value TRIPL-4 also keeps TRIPL-412.
--event-type ID	Only events of this event type id, from tripl plan types.
--property NAME_OR_ID	Only events whose property list carries this property, by name or id.
--silent-since-days N	Only events the warehouse has not carried for N days, 0–3650.
--reviewed / --unreviewed	Only events already marked reviewed, or only those not. Mutually exclusive; omitting both asks for either. Reviewing is a separate axis from lifecycle status, so --reviewed and --status in_review can both match the same event.
--offset N	Skip N events, to read the next page. Default 0.
--limit N	How many events to ask for, 1–10000, default 200.
--order-by ORDER	Order the page: catalog, the authored catalog order, or volume, busiest-first by ingested volume over the last 24h, or health, least healthy first by the health score (main plan only). Unlike --limit this flag has no client-side default — omitting it leaves the parameter off the wire so the API's own default (catalog) applies.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

The lifecycle states are draft, in_review, ready_for_dev, implemented, live, deprecated and archived — the API's own EventStatus enum, checked against backend/openapi.json by a contract test rather than transcribed and hoped over.

tripl events list --project prod --limit 2

  evt-2  app.purchase.completed  draft  never seen

2 of 412 events shown; raise --limit or pass --offset to read the rest.

The columns are the event id, its name, its lifecycle state, when the warehouse last carried it, and an open-drift count when there is one. never seen is the row worth scanning for: an event that is declared, implemented on paper, and has never actually arrived.

warning

2 events. and 2 of 412 events shown. are different sentences

A page that filled up and a catalog that ended print the identical rows. The footer is the only thing that tells them apart, which is why total — the count the API takes before paging — is read and reported rather than inferred from the row count. It is the same class of mistake as reading a 404 as an empty list, one level up: not "we could not look", but "we stopped looking and said nothing".

--offset 200 walks to the next page; --limit 10000 asks for the lot in one request. The JSON carries total, offset, limit and a derived truncated so a consumer never has to do that arithmetic itself.

note

--silent-since-days is the one filter worth a runbook entry

tripl events list --project prod --status live --silent-since-days 30 is the list of events your plan says are live that nothing has sent for a month. That is either a tracking regression nobody noticed or a plan entry nobody retired, and both are worth knowing before a quarterly review rather than after.

Cost: one request, plus one to resolve --branch when you pass it.

      mf-1  TRIPL-412

There is no <event-id> name matching, unlike <scan> and <event-type>. Two events of different types may legitimately carry the same name, so there is no rule that could refuse to guess without also refusing valid input. A wrong id is discovered by the server, as a 404 and exit 1.

Why this costs two requests

An event's field_values carry a field_definition_id and nothing else — no name. So events show reads the event type's field definitions as well and prints each value under the field name it sets. Without that second read the fields block is a column of UUIDs, which is the part of this command worth having, rendered useless.

The meta block does not get the same treatment, and says so in its heading. Resolving a meta_field_definition_id needs the project's meta-field catalog, and the shared request layer builds no route for it. A second spelling of a REST path outside tripl_cli.api is exactly what the contract tests forbid, so the ids are printed honestly instead. Read --json and join against the app if you need the names.

Cost: two requests, plus one to resolve --branch when you pass it.

tripl plan

The event catalog says what is tracked. The plan says what shape it is declared to have: which event types exist, what fields they require, which ${variable} placeholders are documented, and which branches carry unreviewed changes.

usage: tripl plan [-h] [--url URL] [--api-key KEY] [--config PATH] <verb> ...

Five verbs: types, fields, variables, branches and search. A bare tripl plan prints this group's help on stderr and exits 2. Every verb takes exactly one --project, and every one except branches takes --branch.

note

Why plan types and not event-types list

The grammar everywhere else is <plural-noun> <verb> — scans list, drifts dismiss, events show. plan types bends it: types names a kind, not an action.

The alternative was one top-level group per REST collection — event-types list, variables list, branches list, search — which is four more entries in tripl --help for four reads, and that is the same objection that rejected list-scans. Nobody arrives at a terminal wanting to query the event-types collection; they arrive wanting to know what the plan looks like. This is one group per question, not one per collection.

The --branch flag

Every plan read is answered from exactly one revision. Without --branch that is the live main plan; with it, the named branch.

tripl plan branches --project prod           # find the name
tripl plan fields app.purchase --project prod --branch checkout-redesign

--branch takes a name or an id, matched exactly — name first, then id, never a substring and never case-insensitively. It is literally the matcher <scan> uses, for the same reason: a --branch that silently resolved to the wrong revision would answer plan questions about a plan you are not looking at, and a read that is quietly wrong is worse than one that refuses. A selector matching nothing exits 2 and lists the candidates.

note

--branch main reads the live plan too

The API resolves main by the ?branch= parameter being absent, and treats main's own id, as GET /branches lists it, exactly the same. Any other non-empty value must parse as a UUID belonging to the project or the request is refused (400 for a malformed id, 404 for one belonging to another project). --branch is matched against that listing, where main appears under the name main, a name no other branch can take. So --branch main, or main's id, reads the live plan just as omitting the flag does.

Only the output tells the two apart. Without the flag it prints prod with no branch named, and the --json document carries "branch": null. With --branch main it prints prod (branch 'main') and carries main's id and name, as it prints prod (branch 'checkout-redesign') for a working branch.

One consequence worth knowing: ?branch= is contributed by a shared FastAPI dependency, so it is declared on every route that takes plan context at once and appears that way in backend/openapi.json and in generated clients. Its schema there is a plain string rather than a UUID, because the dependency parses the value itself — which is what makes a malformed id the 400 documented above rather than FastAPI's own 422.

tripl plan types

usage: tripl plan types [-h] [--url URL] [--api-key KEY] [--config PATH]
                        [--project SLUG] [--branch REF] [--json]
                        [--timeout SECONDS]

Flag	Meaning
--project SLUG	Required, exactly once.
--branch REF	Read a plan branch instead of the live main plan.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

tripl plan types - https://tripl.example.com (from $TRIPL_BASE_URL)

prod
  et-1  app.screen_view  Screen View  17 fields
  et-2  app.purchase     Purchase     9 fields

2 event types.

The route answers a bare array and pages nothing, so total, offset and limit are all null in the JSON: there is no next page to miss. It is not quite unlimited, though — the service applies a defensive cap of 1,000 event types and reports nothing when it bites, so a project past that number sees a silently short list here and in the app alike.

The field count is derived rather than served; the API embeds the whole field_definitions array on every row. tripl plan fields <event-type> reads one type's definitions.

Cost: one request, plus one to resolve --branch when you pass it.

tripl plan fields

usage: tripl plan fields [-h] [--url URL] [--api-key KEY] [--config PATH]
                         [--project SLUG] [--branch REF] [--json]
                         [--timeout SECONDS]
                         <event-type>

Flag	Meaning
<event-type>	Event type name or id, matched exactly — name first, then id.
--project SLUG	Required, exactly once.
--branch REF	Read a plan branch instead of the live main plan.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

tripl plan fields app.screen_view - https://tripl.example.com (from $TRIPL_BASE_URL)

prod (branch 'checkout-redesign')
  fd-1  screen_name  string  required  pii   enum: checkout|cart
  fd-2  cart_value   number  optional  none

2 fields.

The columns are the definition id, the field name, its type, whether it is required, its sensitivity, and its enum options if it has any. This is what a value has to satisfy — read it before writing field_values through the app or an agent, and read it when a enum_violation drift appears and you want to know what the declared set actually is.

The enum options go last and unabbreviated. The last column is never padded, so a forty-value enum costs the rows around it nothing.

<event-type> is resolved on the branch you named, not on main: a type that exists only on a branch has no id to find on main, and one renamed on a branch would otherwise resolve against the wrong name.

Cost: two requests — the event-type listing, to resolve <event-type>, then the fields — plus one to resolve --branch when you pass it.

tripl plan properties

usage: tripl plan properties [-h] [--url URL] [--api-key KEY] [--config PATH]
                             [--project SLUG] [--branch REF] [--offset N]
                             [--limit N] [--json] [--timeout SECONDS]

tripl plan variables is the same command under its former name.

Flag	Meaning
--project SLUG	Required, exactly once.
--branch REF	Read a plan branch instead of the live main plan.
--offset N	Skip N properties, to read the next page. Default 0.
--limit N	How many properties to ask for, 1–5000, default 200.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

tripl plan properties - https://tripl.example.com (from $TRIPL_BASE_URL)

prod
  var-1  cart_value  number  12 events  1 open drift
  var-2  screen      string  40 events

2 properties.

Properties are the documented ${placeholder} tokens an event name or field value may carry. The columns are the id, the name, the declared type, how many events use it, and its open value drift count — a variable observed carrying a value outside its documented set. A non-zero count there is the same class of signal tripl drifts list reports for schema, on the other axis.

The ceiling is 5000 rather than the events route's 10000 because that is what the route enforces; a real project can carry well over a thousand variables, so the default of 200 is a page and not the catalog.

Cost: one request, plus one to resolve --branch when you pass it.

tripl plan branches

usage: tripl plan branches [-h] [--url URL] [--api-key KEY] [--config PATH]
                           [--project SLUG] [--json] [--timeout SECONDS]

Flag	Meaning
--project SLUG	Required, exactly once.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

No --branch. The branch listing is a property of the project, not of a revision, so there is no ?branch= for it to send and a flag that quietly did nothing would read as one that did something.

tripl plan branches - https://tripl.example.com (from $TRIPL_BASE_URL)

prod
  b-0001  main               main     merged  -
  b-9f21  checkout-redesign  working  draft   3 ahead  behind base

2 branches.

The columns are the branch id, its name, its kind (main or working), its status (draft, ready_for_review, changes_requested, approved, merged, closed), how many changes it is ahead of its base, and whether its base has moved under it. Both are computed for open branches only: a merged or closed row shows - and no behind base, like main.

behind base is the one to act on. A branch whose base has moved has a diff that no longer describes what merging it would do — rebase it in the app before anyone reviews it.

This command exists mostly to give you the name to pass to --branch.

What is deliberately not here

tripl plan diff is not shipped, though the route exists and the MCP server's get_branch_diff tool reads it. The diff answers {behind_base, entries, renames, summary} — not a list — so it does not fit the one document shape the seven read verbs share, and behind_base is too load-bearing to smuggle into an items array. renames makes that worse rather than better: it is a second top-level key, and one that points at entries — each pair naming the removal and the addition that are really one renamed row, which a merge applies as a single in-place update — so flattening the document to a list would drop the pairing on the floor. A second document shape for one verb is worse than not shipping it yet.

Merging, reverting and branch transitions are not here either, and never will be: both surfaces hand that decision back to a human in the tripl app, which is where the conflict resolution and the review state live.

Cost: one request.

tripl plan search

usage: tripl plan search [-h] [--url URL] [--api-key KEY] [--config PATH]
                         [--project SLUG] [--branch REF] [--type TYPE]
                         [--limit N] [--json] [--timeout SECONDS]
                         <query>

Flag	Meaning
<query>	Phrase or partial name, 1–500 characters. Stripped, and a blank one is exit 2.
--project SLUG	Required, exactly once.
--branch REF	Read a plan branch instead of the live main plan.
--type TYPE	Restrict to one entity kind. Repeatable.
--limit N	How many hits to ask for, 1–100, default 20.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

The entity kinds are event, event_type, field, meta_field, variable, relation, tag, metric, fact_table, scan_config, alert_rule and doc — the API's own list, pinned to backend/openapi.json by a contract test. doc is a note of the docs catalog, project or organization; read it with tripl docs cat.

The last two are project configuration rather than plan content, and each is indexed with the text you would look for it by: a scan carries the columns it is wired to and the warehouse SQL it runs, so --type scan_config answers "which scan reads this table"; an alert rule carries its message and item templates.

tripl plan search 'checkout funnel' --project prod --type event --limit 2

tripl plan search - https://tripl.example.com (from $TRIPL_BASE_URL)

prod
  event  evt-1  app.purchase.completed  Purchase  0.92
  event  evt-7  app.checkout.started    Checkout  0.61

2 search results shown — the most this page holds, and more may have matched; raise --limit.

The columns are the entity kind, its id, its title, its subtitle and a confidence in [0, 1]. The id is in the table rather than only in the JSON because it is the argument the follow-up takes: search, then read the entity by id with tripl events show or tripl plan fields.

warning

Search is capped by --limit alone

There is no --offset, because the route has no offset parameter — a hit past --limit is unreachable except by raising it, and the truncation line says exactly that rather than advising a flag that cannot exist. The JSON reports "offset": null for the same reason.

"total" is null too, and that is not an omission: the route computes its total after trimming to the limit, so it always equals the page and can never say how many matched. Reporting it would have read 2 of 2 search results shown on a search that dropped hits. The warning above comes from the route's own truncated instead — search retrieves one row past the window it ranks, so it reports whether a hit was dropped rather than inferring it from a page that happens to be full. That inference survives only as the fallback for an instance too old to report the flag. Either way the line warns without a number, because there is no count to warn with.

note

Read semantic_used before you trust a low score

The --json document carries meta.semantic_used. When it is false the instance answered from substring matching rather than the semantic index — the scores mean something different, and a phrase that would have matched semantically may be missing entirely. A ranking consumer that ignores this will silently change behaviour the day the index is rebuilt.

Cost: one request, plus one to resolve --branch when you pass it.

tripl annotate

Posts one marker onto every monitoring (Volume tab) chart in a project — "Deployed web 2026.09.25", with a link to the release — so the next anomaly on a chart sits next to the deploy that probably caused it. It is written for a CI step: one request, no prompt, and safe to retry.

usage: tripl annotate [-h] [--base-url URL] [--api-key KEY] [--config PATH]
                      [--project SLUG] [--url URL] [--at TIMESTAMP]
                      [--description TEXT]
                      [--scope-type {project_total,event_type,event,metric}]
                      [--scope-ref REF] [--dry-run] [--json]
                      [--timeout SECONDS]
                      <label>

Flag	Meaning
<label>	The text drawn on the chart, 1–200 characters.
--project SLUG	Required, exactly once.
--url URL	The release or pull-request link the chart tooltip opens. http or https, at most 500 characters.
--at TIMESTAMP	When it happened, RFC 3339 (2026-09-25T14:02:00Z). A value with no offset is read as UTC. Default: now.
--description TEXT	Longer text for the tooltip, up to 2000 characters.
--scope-type TYPE	Draw it only on charts of this scope: project_total, event_type, event or metric. Needs --scope-ref. Omit both for a project-level marker, which every monitoring (Volume tab) chart in the project shows.
--scope-ref REF	The event type, event or metric the scope names. Needs --scope-type.
--dry-run	Build the request, print it, send nothing.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Write. Needs a tk_w_ key backed by an editor or owner. Does not prompt, and has no --yes.

warning

--url here is the link, not the instance

On every other command --url is the instance URL. On annotate it is the link the annotation carries, because that is the API field's name and the flag every CI example reaches for. Give the instance with $TRIPL_BASE_URL (the usual case in CI), --base-url, or --url placed before the command name: tripl --url https://tripl.example.com annotate ....

tripl annotate "Deployed web 2026.09.25" --project prod \
  --url https://github.com/acme/web/releases/tag/2026.09.25

tripl annotate - https://tripl.example.com (from $TRIPL_BASE_URL)

prod: annotated 'Deployed web 2026.09.25' at 2026-09-25T14:02:00Z (ann-7f3a).

The annotation is created with source api. Charts draw it muted, with a rocket icon, and hide it together with the automatic release markers when a viewer turns Show releases off — see Chart annotations.

A 200 means it was already there

The API de-duplicates api annotations: the same label with source api, posted to the same project within 24 hours, returns the annotation that already exists — with a 200 instead of a 201 — rather than drawing it twice. A re-run deploy job therefore leaves one marker, not two. (Only api and the worker's release markers are de-duplicated; manual annotations from the app's form never are.) annotate still exits 0, and says which of the two happened:

tripl annotate - https://tripl.example.com (from $TRIPL_BASE_URL)

prod: annotation 'Deployed web 2026.09.25' already exists (ann-7f3a, at 2026-09-25T14:02:00Z); the API de-duplicated it and nothing new was created.

Under --json the same fact is "deduplicated": true in the mutation document. Put something unique in the label — the version, the commit — if two deploys a day are two separate events.

The same request without the CLI is in the Agent API guide.

Cost: one request, or none with --dry-run. The slug is not resolved first: a wrong one comes back as the route's own 404.

tripl check

Checks tracking code against the plan: unknown events, unknown fields, values the plan does not allow and, for captured events, missing required fields. It is built for a CI step. The configuration (which functions track which event type) lives in .tripl/check.yml in your repository. The tripl check guide covers the whole file, the presets, enum sources and interpolated names.

usage: tripl check [-h] [--url URL] [--api-key KEY] [--config PATH]
                   [--check-config PATH] [--project SLUG] [--branch REF]
                   [--payloads FILE] [--strict] [--format {text,json,sarif}]
                   [--json] [--timeout SECONDS]

Flag	Meaning
--check-config PATH	The check configuration to read. Default: the nearest .tripl/check.yml (or .yaml, or .json) in the current directory or a parent, up to the repository root. (--config is the connection config file, as on every other command.)
--project SLUG	The project to check against. Overrides project in the check configuration. One of the two is required.
--branch REF	Check against a plan branch instead of the live main plan. Name or id, matched exactly, like tripl plan --branch. Overrides branch in the check configuration.
--payloads FILE	Payload mode: validate the events in FILE (NDJSON, a JSON array, or one object; - reads stdin) instead of scanning source files. A missing required field is an error in this mode.
--strict	Fail on warnings too. Also report a dynamic_value finding for every value the scanner could not read, and list the calls where nothing was readable (status dynamic) as warnings.
--format FORMAT	text (the default), json, or sarif for a SARIF 2.1.0 log.
--json	One JSON document on stdout, every human line on stderr. The same as --format json.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Read-only. A tk_r_ key is enough. The request is a POST only because it carries the calls it found, up to 5,000 per request, to POST /projects/{slug}/plan/validate. It changes nothing.

tripl check                                   # static: scan the sources in .tripl/check.yml
tripl check --payloads build/events.ndjson    # payload: validate captured events
tripl check --branch checkout-redesign --format sarif > tripl-check.sarif

214 call sites in 58 files: 211 ok, 1 warning, 2 errors.

Items that pass are counted, not listed. Each listed item shows its location, status, event type and identity (or name), then one indented line per finding. With --strict, calls whose status is dynamic are listed too.

Findings use the codes in the guide's findings table: unknown_event_type, unknown_event, deprecated_event, unknown_field, missing_required_field, value_not_allowed, dynamic_value, too_dynamic, policy_violation, oversize_value and no_verdict.

Exit codes. 0 when there is no error (and, with --strict, no warning). 1 when there is at least one, or when a request failed. 2 on a configuration or usage error. See Exit codes.

tripl codegen

Generates typed tracking code from the plan: Swift, Kotlin and TypeScript files whose enums and event types come from the plan's values, calling your own tracking wrapper. What is generated for each event type (its style, languages, transport and templates) is configured in a codegen block in the same .tripl/check.yml that tripl check reads, and a top-level codegen block sets the output directories, the default languages and the Kotlin package. The code generation guide covers the styles, the configuration, the generated code and custom templates. The generated shapes are the industry-standard ones and have no switches; a team whose code has another shape builds it with its own templates, vars and extra files (see Building your own shape).

usage: tripl codegen [-h] [--url URL] [--api-key KEY] [--config PATH]
                     [--lang LANG] [--out DIR] [--check-config PATH]
                     [--project SLUG] [--branch REF] [--model FILE] [--check]
                     [--json] [--timeout SECONDS]

Flag	Meaning
--lang LANG	Only this language: swift, kotlin or ts. Repeat it for more than one. Default: each event type's own languages (the top-level codegen.languages, else all three).
--out DIR	Write into DIR instead of the codegen.out directories. DIR itself when the run writes one language, DIR/<lang> when it writes several. Created when missing. Without --out and without codegen.out, the run is a configuration error.
--check-config PATH	The configuration to read, as for tripl check. Default: the nearest .tripl/check.yml (or .yaml, or .json) at or above the current directory, up to the repository root. Only event types with a codegen block are generated.
--project SLUG	The project to read the plan from. Overrides project in the configuration. One of the two is required.
--branch REF	Generate from a plan branch instead of the live main plan. Name or id, matched exactly, like tripl plan --branch. Overrides branch in the configuration. Not allowed with --model.
--model FILE	Read a saved codegen_model export (from tripl export --format codegen_model) instead of asking the instance. No request is sent, and the header line reads offline (from --model).
--check	Write nothing. Render every file, compare it with what is on disk, and exit 1 when any file is missing, differs or is stale, naming each one. For CI.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Read-only. A tk_r_ key is enough. It reads GET /projects/{slug}/plan/export?format=codegen_model once and renders everything locally. It writes one file per event type and language, named after the event type's namespace (AppEvents.swift, AppEvents.kt, appEvents.ts), plus one shared file per language that declares TriplDestination: TriplTransport.swift, TriplTransport.kt and triplTransport.ts. Output is deterministic: the header names the project, the branch and the plan's content hash, not its revision, and carries no timestamp, so re-running against an unchanged plan rewrites nothing.

A write also removes stale files, ones an earlier run generated that this run no longer produces. Only files whose header names the same project, in a language this run writes into that directory, are ever removed; --check reports them as stale instead.

tripl codegen                                        # write into the codegen.out directories
tripl codegen --check                                # CI: exit 1 when a file is out of date
tripl codegen --lang swift --out App/Generated       # one language, straight into App/Generated
tripl export --format codegen_model --out build      # save the plan once...
tripl codegen --model build/codegen_model.json       # ...and generate from it offline

The output of the first run on the CLI's test fixture (cli/tests/codegen, with codegen: {out: generated} and --model):

15 files from the plan (revision 9b1f0c52-5d0e-4d6a-8a31-2f6c0e7d4a42 of main): 15 created, 0 changed, 0 unchanged, 0 stale removed.

Each file's status is created, changed, unchanged or stale. Under --check, the last line says instead that the files are in sync with the plan, or how many of them are out of date, with a reminder to run tripl codegen and commit the result. The plan revision appears only in this line and in the JSON document, never in the files.

With --json, the document carries project, branch, revision, check, exit_code and files, one entry per file with path, language, event_type (null for the shared transport file and for a stale file) and status.

Exit codes. 0 when the files were written, or with --check when every file matches. 1 with --check when a file is missing, differs or is stale, or when the request failed or a file could not be written. 2 on a configuration or usage error, including no check configuration, no event type with a codegen block, no output directory, and --model with --branch. See Exit codes.

Cost: one request, plus one to resolve --branch when you pass it. None with --model.

In a GitHub Actions workflow

- name: Generated tracking code matches the plan
  env:
    TRIPL_BASE_URL: https://tripl.example.com
    TRIPL_API_KEY: ${{ secrets.TRIPL_READ_ONLY_KEY }}
  run: uvx tripl codegen --check

This checks every language in one step when the configuration sets codegen.out. The guide has the full workflow.

tripl export

Exports the plan in one of two formats. jsonschema is a bundle of JSON Schema (draft 2020-12) documents, one per live event, for validators and generators outside tripl; it is the same bundle the Export JSON Schema button on the Plan history page downloads. codegen_model is the plan as tripl codegen reads it, for tripl codegen --model (offline generation, custom template development).

usage: tripl export [-h] [--url URL] [--api-key KEY] [--config PATH]
                    --format {jsonschema,codegen_model} [--out DIR]
                    [--check-config PATH] [--project SLUG] [--branch REF]
                    [--json] [--timeout SECONDS]

Flag	Meaning
--format FORMAT	jsonschema or codegen_model. Required, so that a future format is never picked by default.
--out DIR	Write into DIR (created when missing). Without it, the export is printed to stdout as JSON and nothing else is printed.
--check-config PATH	Read project and branch from this configuration. Default: the nearest .tripl/check.yml (or .yaml, or .json), as for tripl check. Optional: without one, pass --project.
--project SLUG	The project to export. Overrides project in the configuration. One of the two is required.
--branch REF	Export a plan branch instead of the live main plan. Name or id, matched exactly, like tripl plan --branch. Overrides branch in the configuration.
--json	One JSON document on stdout, every human line on stderr. Needs --out, because without it stdout holds the export.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Read-only. A tk_r_ key is enough. It reads GET /projects/{slug}/plan/export once. With --out DIR it writes:

Format	Files
jsonschema	DIR/bundle.json, the whole bundle as served, and DIR/<event type>/<identity>.schema.json, one schema per event.
codegen_model	DIR/codegen_model.json.

File names come from plan strings, so they are reduced to [A-Za-z0-9._-] and can never leave DIR; two identities that reduce alike get -2, -3. JSON is written with sorted keys and a trailing newline, so a committed export diffs cleanly between revisions. It then prints one line: Exported <N> event schemas of <project> (<branch>, revision <revision>) to <DIR>: <count> files. (the codegen model instead of the schema count for codegen_model). With --json, the document carries project, branch, format, revision, files (the paths written) and schemas (the number of event schemas, 0 for codegen_model).

In a jsonschema export, archived events are left out and deprecated ones are marked. Each schema has the event type's fields as properties, required fields in required, the event's own values as const, enums from the field's options or the variable's allowed values, and pattern, minimum and maximum from the field's contract. The API guide has the full mapping, and the codegen_model format too.

tripl export --project shop --format jsonschema --out build/plan-schema
tripl export --project shop --branch checkout-redesign --format jsonschema --out build/plan-schema
tripl export --project shop --format codegen_model > codegen_model.json

Exit codes. 0 when the export was written or printed. 1 when the request failed or a file could not be written. 2 on a usage or configuration error: a missing --format, --json without --out, no project from either --project or the configuration, or a configuration that does not parse. See Exit codes.

Cost: one request, plus one to resolve --branch when you pass it.

tripl docs

Reads and syncs the docs catalog: Markdown notes for people and for AI agents, such as warehouse gotchas, event query recipes and onboarding guides. Notes live at two levels. Project notes belong to one project. Organization notes belong to the project's organization and show up in every project of it. --scope picks one: project or organization.

Each note is one Markdown file at a path such as guides/setup.md. Folders are just the paths, so there are no empty folders. A note may start with YAML frontmatter. The API reads title, description, tags and audience (human, agent or both) from it. Any other key is kept as written, so an agent skill's SKILL.md with name and allowed-tools round-trips unchanged. The catalog is not branch-aware: every note has one version, and a [[event:NAME]] link inside it resolves against the main plan.

tripl docs ls --project prod --audience agent
tripl docs cat guides/warehouse-gotchas.md --project prod
tripl docs pull ./notes --project prod
tripl docs push ./checkout-skill --project prod --keep-root

ls, cat and pull only read and need nothing but a tk_r_ key. push writes: it needs a tk_w_ key backed by an editor or owner, and follows the write safety rules. Organization notes use the same rule today. The API will narrow organization writes to organization owners and admins once organization membership exists.

Every verb sees what the key's user sees. A note that is not shared with that user (see Sharing) is missing from ls, cat and pull, and cat answers "not found" for it, exactly as for a note that does not exist. With a key of an organization owner or admin, cat still reads such a note by its path; that read is recorded in the audit log as doc.break_glass_read, and the note never shows in ls or pull. push never changes a note's sharing: frontmatter carries no visibility, and new notes get the default or their folder's setting.

The service's limits: a note is at most 256 KiB, and one push carries at most 2000 files and 20 MiB in total. push checks all three before it sends anything.

Moving, renaming and deleting a single note, and a note's revision history, stay in the app, where the diff and the Restore button are.

tripl docs ls

usage: tripl docs ls [-h] [--url URL] [--api-key KEY] [--config PATH]
                     [--project SLUG] [--scope {project,organization,all}]
                     [--audience {human,agent,both}] [--json]
                     [--timeout SECONDS]

Flag	Meaning
--project SLUG	Required, exactly once.
--scope SCOPE	project, organization or all, default all.
--audience AUDIENCE	Keep notes written for this reader. A note marked both matches human and agent; --audience both keeps only those.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

tripl docs ls - https://tripl.example.com (from $TRIPL_BASE_URL)

prod
  project       guides/warehouse-gotchas.md  both   r3  Warehouse gotchas
  organization  recipes/event-queries.md     agent  r1  Event query recipes

2 docs.

The columns are the scope, the path, the audience, the current revision and the title. The --json document is the events and plan shape with kind: "doc", and each item is the API's DocSummary as sent.

Cost: one request.

tripl docs cat

usage: tripl docs cat [-h] [--url URL] [--api-key KEY] [--config PATH]
                      [--lang <code>] [--project SLUG]
                      [--scope {project,organization}] [--json]
                      [--timeout SECONDS]
                      <path>

Flag	Meaning
<path>	The note's path, e.g. guides/setup.md.
--project SLUG	Required, exactly once.
--scope SCOPE	project or organization, default project.
--lang CODE	A stored translation to print (e.g. en), or original. Without it, the project's language for agents when that translation is up to date, else the original.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

When the language printed is not the one asked for (no translation, one still being made or failed, or one behind the original), a note: line on stderr says so. See Translations.

Prints the note exactly as stored, frontmatter included, and nothing else on stdout: no header and no added newline. tripl docs cat x.md > x.md therefore round-trips. A link the API cannot resolve to exactly one target is reported on stderr as warning: broken link [[event:NAME]] (or ambiguous link), and the exit code stays 0. With --json the document has kind: "doc_file", and its one item is the API's DocFileResponse, with the parsed frontmatter and every link's status.

Cost: one request.

tripl docs pull

usage: tripl docs pull [-h] [--url URL] [--api-key KEY] [--config PATH]
                       [--project SLUG] [--scope {project,organization}]
                       [--force] [--json] [--timeout SECONDS]
                       <dir>

Flag	Meaning
<dir>	The folder to write into. Created when it does not exist.
--project SLUG	Required, exactly once.
--scope SCOPE	project or organization, default project.
--force	Write into a folder that is not empty.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600.

Exports one scope and writes each note to <dir>/<path> as raw UTF-8 bytes, so the line endings the note was stored with survive. Three rules protect the folder:

• A non-empty folder needs --force. That is checked before the export is requested, so the refusal is exit 2 and costs no request. With --force, the files the export carries are overwritten (or left alone when identical) and nothing else is touched.
• No local file is ever deleted. A note deleted in the app stays on disk until you remove it.
• Every path is checked before the first write. An absolute path, a .. segment, a backslash, or a path that resolves outside <dir> through a symlinked folder refuses the whole pull with exit 1, and nothing is written. A symlink where a note would land is refused the same way.

The --json document has kind: "pulled_file". Each item has path, local_path, size_bytes, sha256 and action: written, overwritten or unchanged.

Cost: one request.

tripl docs push

usage: tripl docs push [-h] [--url URL] [--api-key KEY] [--config PATH]
                       [--project SLUG] [--scope {project,organization}]
                       [--mirror] [--keep-root] [--dry-run] [--yes] [--json]
                       [--timeout SECONDS]
                       <dir>

Flag	Meaning
<dir>	The folder to upload.
--project SLUG	Required, exactly once.
--scope SCOPE	project or organization, default project.
--mirror	Also delete every note of the scope that the folder does not carry. On organization the API refuses it to every API key: only an organization owner or admin, signed in to the web app, can mirror organization notes.
--keep-root	Prefix every path with the folder's own name: ./checkout-skill uploads checkout-skill/SKILL.md instead of SKILL.md.
--dry-run	Walk the folder and print the request, and send nothing.
--yes	Skip the preview and the question. Required when stdin is not a terminal.
--json	One JSON document on stdout, every human line on stderr.
--timeout SECONDS	Per-request timeout, default 10.0, range 0.1–600. Raise it for a large folder.

Uploads every *.md under <dir> as one import. The walk does not follow symlinks, and it skips anything that is not a note. A skipped file is listed with its reason and never fails the push:

• files that are not .md, such as an agent skill's scripts/ and assets/
• hidden files and directories, such as .git and .DS_Store
• symlinks

Notes at an existing path are updated. A note whose content is identical is left alone and gets no new revision. A leading byte-order mark is dropped, because the API reads frontmatter only when --- is the very first byte.

push refuses with exit 2, before anything is sent, in these cases:

• a note is over 256 KiB or is not UTF-8 (every such file is named)
• the folder is over one import's limits
• the folder holds no .md file at all. Under --mirror that upload would delete every note of the scope.

It asks first, and the question is not a guess. On a terminal, push first posts the same bundle with dry_run=true. That request changes nothing, and its answer says how many notes would be created, updated, left unchanged and deleted:

preview: 1 created, 2 updated, 5 unchanged, 0 deleted.
  created  references/events.md
  updated  SKILL.md
  updated  references/warehouse.md
Push 8 Markdown files from ./checkout-skill into the project notes of prod? 1 created, 2 updated, 5 unchanged, 0 deleted. [y/N]

Declining there exits 1 with tripl: aborted. Nothing was changed. With --yes, there is no preview and no question, and exactly one request goes out. If the API refuses a note (invalid frontmatter, a path it will not take), the whole import is refused, nothing is changed, and the command exits 1 with the API's list of errors.

The --json document is the mutation document with action set to the mode, merge or mirror, and result set to the API's import result. Its request.body.files lists each file's path and size_bytes rather than its content, so a twenty-megabyte upload is not repeated in your terminal.

Cost: one request with --yes, and two on a terminal (the preview, then the import).

tripl install

Every command above needs an instance to talk to. This is the one that makes one. It is the executable form of Self-hosting & Deployment — same compose file, same variables, same pull and up -d — with the secret generation and the file permissions done for you instead of copied out of a code block.

usage: tripl install [-h] [--url URL] [--api-key KEY] [--config PATH]
                     --app-url URL [--dir PATH] [--version TAG]
                     [--edition {community,enterprise}] [--telemetry]
                     [--wait SECONDS] [--no-start] [--force] [--dry-run]
                     [--yes] [--json]

Flag	Meaning
--app-url URL	Required, no default. The public origin of the instance you are creating, e.g. https://tripl.example.com. Becomes APP_BASE_URL, which drives CORS and cookies. A trailing / or a pasted /api/v1 is trimmed.
--dir PATH	Where the stack lives. Default ./tripl; always reported absolute, whatever you typed.
--version TAG	Image tag to pin in .env. Default latest. Must look like a Docker tag — a letter, digit or underscore followed by up to 127 of [A-Za-z0-9._-].
--edition NAME	Which image .env pins as TRIPL_IMAGE: community (the default, ghcr.io/tripl-io/tripl) or enterprise (ghcr.io/tripl-io/tripl-enterprise). The Enterprise image is private, so run docker login ghcr.io with the credentials that come with your subscription before install pulls it; install prints that reminder and holds no credentials itself. Like --version, it does not change an existing .env.
--telemetry	Share anonymous usage telemetry: the new .env gets TELEMETRY_ENABLED=true instead of false — one small ping a day, no names, emails, hosts or data (what it holds). Asked once, here: like --version, it does not change an existing .env; edit that file to change your mind.
--wait SECONDS	How long to poll /health before giving up. Default 300, range 0–3600. 0 skips waiting entirely — it does not mean "probe once".
--no-start	Write the files and run nothing. Also skips the Docker probe, so it works on a machine with no Docker at all.
--force	Replace a compose.yaml or rabbitmq.conf that differs from the packaged one. Never reaches .env.
--dry-run	Print the plan; write nothing, run nothing.
--yes	Skip the confirmation prompt. Required when stdin is not a terminal and a prompt would be asked — see when it asks.
--json	One JSON document on stdout, every human line on stderr.

note

--url and --api-key are inherited, and refused

Both appear in the usage line because every subcommand shares one parent parser. Passing either explicitly to install or upgrade is exit 2, with a message naming --app-url instead. These commands act on a directory; a connection flag that was silently ignored is how an operator provisions the wrong box and finds out later.

tripl install --app-url https://tripl.example.com --version 1.5.0 --dir /srv/tripl

--dry-run prints exactly what a real run would do, and is worth typing first. Here without --version, so the plan shows the latest default:

tripl install --app-url https://tripl.example.com --dir /srv/tripl --dry-run

tripl install - /srv/tripl

app url  https://tripl.example.com
image    ghcr.io/tripl-io/tripl:latest

files
  compose.yaml                  create  0644
  infra/rabbitmq/rabbitmq.conf  create  0644
  .env                          create  0600
  generated into .env, values never printed: ENCRYPTION_KEY, SECRET_KEY, POSTGRES_PASSWORD, RABBITMQ_PASSWORD

commands
  + cd /srv/tripl && docker compose pull
  + cd /srv/tripl && docker compose up -d
  then poll https://tripl.example.com/health for up to 300s

dry run: nothing was written and nothing was run.

That is stdout in full. Two more lines can land on stderr, and both are warnings rather than refusals, because only you know whether they apply:

• Leaving --version at latest prints a reminder to pin a released tag in production, since latest follows every release and a re-run would move you.
• An http:// --app-url prints a warning that the stack forces SESSION_COOKIE_SECURE=true, so a browser will not store the session cookie over plain HTTP — Safari refuses it even on localhost — and nobody will stay signed in. Legitimate if you terminate TLS elsewhere; otherwise re-run with an https URL.

The two + cd ... && docker compose ... lines are printed before each command runs, in a real run too. They are shell-quoted, so they are safe to paste — that is the point of printing them.

What it writes

Three files, and only three.

Path (under --dir)	Mode	Contents
compose.yaml	0644	A verbatim copy of the production compose file this repository deploys, minus one block — see below.
infra/rabbitmq/rabbitmq.conf	0644	A verbatim copy. Not optional: compose.yaml bind-mounts it, and Docker's answer to a missing bind-mount source is to create a directory there, after which RabbitMQ fails to start with an error naming neither tripl nor the mount.
.env	0600	Generated. The only file that holds secrets.

There is deliberately no data directory. PostgreSQL lives in the named volume pgdata18 and uploaded event photos in the named volume photos, so backing up --dir backs up your configuration and none of your data.

Each file gets one of five actions, and the same five words appear in the human table and in the --json document:

Action	Meaning
create	It did not exist. Created with the mode above.
unchanged	It exists and is byte-identical to the packaged copy. Nothing is opened.
kept	It exists and differs. Yours is kept; the table says so. --force turns this into replace — for compose.yaml and rabbitmq.conf only.
replace	Written beside the target and renamed over it, so a reader never sees a half-written file.
append	.env only. New keys are appended under a dated comment; nothing already in the file is changed.

The packaged compose.yaml differs from the repository's in exactly one way: the mcp service's build: block is removed, because a fresh host has no source tree and modern compose builds when an image is absent locally. --profile mcp therefore pulls the published tripl-mcp image rather than trying to build it. A contract test asserts the rest is byte-identical, so the file you get is the file this project deploys.

The generated .env

# tripl instance configuration, generated by `tripl install` on 2026-08-01T09:00:00Z.
#
# Docker Compose reads this file to INTERPOLATE compose.yaml. The containers receive
# only the variables compose.yaml lists in its environment map, so a variable added
# here that compose.yaml does not mention reaches nothing. Every tunable is listed at
# https://docs.tripl.io/run/configuration
#
# This file holds live secrets: mode 600, and it must stay out of version control.
# Back up ENCRYPTION_KEY separately from the database - warehouse and alert-
# destination credentials are encrypted with it and cannot be recovered without it.

# Public origin of this instance. Drives CORS, and must be the exact origin a browser
# reaches. The stack forces SESSION_COOKIE_SECURE=true, so this should be https.
APP_BASE_URL=https://tripl.example.com

# Released image and tag. `tripl upgrade --to X.Y.Z` moves the tag.
TRIPL_IMAGE=ghcr.io/tripl-io/tripl
TRIPL_VERSION=1.5.0

# Generated secrets - do not edit by hand.
# ENCRYPTION_KEY is a Fernet key: 32 random bytes, url-safe base64.
ENCRYPTION_KEY=...
SECRET_KEY=...
POSTGRES_PASSWORD=...
RABBITMQ_PASSWORD=...

Eight variables, and that is the whole file. It is not a copy of .env.example, which is the backend development template and is full of localhost URLs and keys compose.yaml never reads.

Variable	How it is produced
APP_BASE_URL	Your --app-url, normalised.
TRIPL_IMAGE	ghcr.io/tripl-io/tripl, or ghcr.io/tripl-io/tripl-enterprise with --edition enterprise.
TRIPL_VERSION	Your --version, default latest.
ENCRYPTION_KEY	32 random bytes, url-safe base64 — 44 characters. This is exactly what a Fernet key is, which is what the backend builds from it at startup.
SECRET_KEY	secrets.token_urlsafe(48) — 64 url-safe characters.
POSTGRES_PASSWORD	secrets.token_hex(24) — 48 hex characters.
RABBITMQ_PASSWORD	secrets.token_hex(24) — 48 hex characters.
TELEMETRY_ENABLED	false, or true with --telemetry (telemetry).

The two passwords are hex on purpose, not for looks. compose.yaml builds postgresql+asyncpg://tripl:${POSTGRES_PASSWORD}@postgres:5432/tripl by plain string interpolation, so a base64 password containing /, +, @ or : corrupts the URL into something that fails to connect with an error naming neither the password nor the encoding. Hex has no such character. Neither password can come out as tripl or guest, the dev defaults the backend's assert_production_ready() refuses outright.

No generated value is ever printed, and you should keep it that way

The plan, the human output and the --json document name the keys (secrets_generated) and never the values. A secret printed to a terminal is a secret in a scrollback buffer, in a tee log, and in whatever gets pasted into a ticket. If you need to read one, read the 0600 file.

ENCRYPTION_KEY is the irreplaceable one, and backing it up is a deployment step rather than a CLI one: treat ENCRYPTION_KEY as irreplaceable.

Four rules about writing

1. .env is never overwritten. It is created, or appended to with your confirmation, or left alone. --force does not reach it and there is no flag that does.
2. .env and .env.bak.* are created at 0600 by the open call itself, never opened and then chmod-ed — that would leave a window, however short, in which the database password and SECRET_KEY were world-readable. If an existing .env is readable by other users, you get a warning on stderr and a chmod 600 to run; the CLI will not change the mode of a file it did not create.
3. A compose.yaml that differs from ours is yours. It is reported and kept.
4. The version pin is rewritten by copy-then-replace, preserving every other byte: comments, blank lines, key order and the trailing newline.

install also refuses to run against a tripl source checkout — a directory containing .git or backend/src/tripl — because it writes its own compose.yaml and would land next to the real one. That is exit 2, and the fix is one --dir.

install only asks in one case

A fresh install does not prompt. The single confirmation is for an existing .env that is missing some required keys: it names them, says nothing already in the file will change, and appends under a dated comment. That is where --yes matters — and where a non-TTY without --yes is exit 2, as everywhere else in this CLI.

Consequence worth knowing for a provisioning script: tripl install in a pipeline needs --yes only if it might meet a half-written .env. Pass it anyway; the alternative is a job that works until the day it does not.

Re-running is the supported way to converge

install is idempotent, not one-shot. A second run against the same directory reports unchanged / kept for the files, leaves .env alone, and still runs pull and up -d, because "make the running stack match what is on disk" is the useful meaning of a re-run.

What actually runs, and where its output goes

+ cd /srv/tripl && docker compose pull
+ cd /srv/tripl && docker compose up -d

No -f compose.yaml and no --project-directory, on purpose: that is compose invoked exactly the way you would by hand, and that page gives the reasons.

Before writing anything, install checks for docker on PATH, then for docker compose version, then for a reachable daemon, and stops at the first failure with the daemon's own stderr echoed under a docker: prefix. A legacy docker-compose v1 binary is detected and named in the error but never used: the compose file relies on depends_on.condition, which v1 ignores, so the schema migration would race the app instead of gating it. All three checks are skipped under --no-start.

compose's output is inherited, never captured

pull and up -d write straight to your terminal — layer progress, and the one line that names a failing service. Nothing wraps them. The cost is that their output cannot appear in the --json document, which carries the argv, the cwd, the env overlay and the returncode of each command instead. If you need the text, it is in your terminal or in the docker compose logs the failure message points you at.

Waiting for /health

docker compose up -d returns as soon as the containers are created, which on a first run is a minute or more before the app answers: the migrate one-shot still has to apply every Alembic revision. So install polls <--app-url>/health every 5 seconds until it answers or --wait runs out.

It polls the public URL, so TLS has to be there already

The poll goes to the origin you passed as --app-url — not to http://localhost:8000. If your reverse proxy is not in front of port 8000 yet, https://tripl.example.com/health will not answer no matter how healthy the stack is, and install reports a timeout and exits 1 after --wait seconds.

That is a sequencing problem, not a failed install. Either put TLS up first, or run tripl install --wait 0, bring the proxy up, and check by hand:

curl -fsS http://127.0.0.1:8000/health     # from the deploy host

A timeout prints where to look, and does not roll anything back — the stack is started:

The stack was started; it just has not answered yet. A first run applies every
Alembic revision before the app boots, which on a slow disk can outlast the
default wait. Look here, in this order:
  cd /srv/tripl && docker compose ps
  cd /srv/tripl && docker compose logs migrate
  cd /srv/tripl && docker compose logs app
  tripl doctor --url https://tripl.example.com

That last line needs an API key you do not have yet

tripl doctor demands both a URL and a key before it opens a socket, even though /health itself needs neither. On a brand-new instance there is no account, so there is no key. Come back to that line after you have created the owner account and a tk_r_ key — the three docker compose lines above it are the ones that work right now.

What install deliberately does not do

It brings up a running, empty instance. It does not create the owner account, it does not connect a warehouse, and it does not run the first scan. Two of those three are unreachable over the API at all, and the third depends on them:

• A data source cannot be created with an API key, of any scope, held by any role. POST /data-sources requires an interactive owner session; a request carrying an API key scope is 403 by construction. Same wall that keeps tripl scans replay out of this CLI.
• An owner account could be registered over the API, and should not be. It would mean accepting a password on an argv — visible through ps(1), kept in shell history — and the session cookie the reply sets is Secure, so over a plain-HTTP first run the cookie is discarded and the "automated" flow breaks silently.

So the last thing install prints is the truth about your instance, read from the unauthenticated /auth/status:

This instance has no accounts yet. Open https://tripl.example.com and create the
first one - it becomes the owner.
Then, signed in as that owner:
  Settings -> Data sources   connect ClickHouse, BigQuery or PostgreSQL. Owner-only,
                             and only from a browser session: an API key cannot reach
                             this endpoint whatever its scope.
  Settings -> API keys       create a tk_r_ key for the CLI.
Then: tripl doctor --url https://tripl.example.com

If the instance already has accounts it says so instead, and if registration is closed it points at Settings → Members → Invite a member. If /auth/status could not be read it says that, and falls back to the general wording — it never guesses. See Members for what happens on that first sign-in, and Connecting a warehouse for the step after it.

tripl upgrade

The most dangerous thing this CLI does, and it is built like it. Moving to a new tag applies Alembic migrations, and those are not reversible here.

usage: tripl upgrade [-h] [--url URL] [--api-key KEY] [--config PATH] --to TAG
                     [--dir PATH] [--wait SECONDS] [--dry-run] [--yes]
                     [--json]

Flag	Meaning
--to TAG	Required. The tag to move to, e.g. 1.5.0. There is no default and no "upgrade to latest" convenience.
--dir PATH	Where the stack lives. Default ./tripl. Must already contain compose.yaml and .env, or it is exit 2 naming tripl install.
--wait SECONDS	As for install: default 300, range 0–3600, 0 skips.
--dry-run	Print the plan; write nothing, run nothing.
--yes	Skip the confirmation. upgrade always confirms, so a non-interactive run always needs this.
--json	One JSON document on stdout, every human line on stderr.

tripl upgrade --to 1.5.0 --dir /srv/tripl --dry-run

tripl upgrade - /srv/tripl

from  1.4.0
to    1.5.0

commands
  + cd /srv/tripl && TRIPL_VERSION=1.5.0 docker compose pull
  + cd /srv/tripl && docker compose up -d
  the 1.5.0 pin is written to .env between the two, after the pull succeeds
  then poll /health for up to 300s

dry run: nothing was written and nothing was run.

The current tag is read out of .env, and so is the origin to poll — you set APP_BASE_URL at install time and being asked for it again is one more chance to type a different one, which is how a CORS mismatch gets introduced during an upgrade. If .env carries no APP_BASE_URL, the health wait is reported as skipped rather than run against a guess.

How the two tags are compared

ordering	When	What happens
same	The pin already equals --to.	already at X; nothing to do. Exit 0, nothing run, .env untouched — a converging provisioning script must not be a failing one.
upgrade	Both are strict X.Y.Z and the target is higher.	Proceeds to the backup gate.
downgrade	Both are strict X.Y.Z and the target is lower.	Refused outright, exit 2, no override flag.
unknown	Either side is not a strict X.Y.Z — latest, 1.4, sha-abc1234.	Prints the plan, then refuses without --yes, exit 2. With --yes it proceeds and warns that this may be a downgrade.

tripl: downgrade refused: 1.4.0 -> 1.3.0. Alembic migrations are not reversible here, so the older image cannot read the schema the newer one wrote. Restore your backup instead. There is no override flag.

There is no override because there is no safe one. Once alembic upgrade head has run, the old image does not know how to read the new schema, and the honest instruction is restore your backup.

The backup gate

upgrade prints the pg_dump command and refuses to continue without an acknowledgement. It never runs it:

backup   cd /srv/tripl && docker compose exec -T postgres \
           pg_dump -U tripl tripl | gzip > tripl-1.4.0.sql.gz
         Take it now. This applies Alembic migrations, which are not reversible.
         ENCRYPTION_KEY lives in .env, not in that dump - back it up separately.

A dump this tool invoked and then called "your backup" would be a promise it cannot keep: it cannot know there is disk space, it cannot verify the dump, and the dump does not contain ENCRYPTION_KEY — without which every encrypted column in it is unreadable.

The prompt names the directory's basename, which is also the compose project name:

Have you taken that backup of tripl? This upgrades 1.4.0 -> 1.5.0 and applies migrations that cannot be undone. [y/N]

Anything but y/yes aborts with exit 1, and on a non-TTY without --yes it is exit 2 — the same rule as every other prompt on this page.

Order of operations, and why

pull  ->  write the pin  ->  up -d

The pull comes first so a bad tag or an unreachable registry leaves .env untouched; the failure message says so explicitly. The pin is written to .env before up -d rather than passed inline, because an inline TRIPL_VERSION=x docker compose pull applies to the pull only and the following up would start ${TRIPL_VERSION:-latest} — the exact trap this ordering exists to avoid. That is why the printed pull line carries the assignment inside the cd, and the up -d line does not.

Rewriting .env first copies it to .env.bak.<UTC> at 0600 and only then moves the pin, preserving every other byte. That backup is created exclusively: a second upgrade in the same second refuses rather than clobbering the only copy of the pin you are moving away from.

upgrade does not run alembic and does not run docker compose run --rm migrate. The migrate one-shot with condition: service_completed_successfully is already the race-free mechanism; a second CLI-owned migration path would be a second thing to keep in sync.

When it fails

The pull failed. .env was never touched. You are still on the old tag and the stack is still running the old image. Fix the tag or the registry access and re-run.

up -d failed. The pin is left at the new tag, on purpose:

The `migrate` one-shot runs `alembic upgrade head` before app and workers start,
so this most likely means the schema upgrade failed. Read it:
  cd /srv/tripl && docker compose logs migrate

TRIPL_VERSION is left at 1.5.0 on purpose. Alembic applies revisions one at a
time, so the schema may be partly upgraded; starting the old image against a
partly-new schema would be worse than leaving the stack stopped. Fix the cause and
re-run `tripl upgrade --to 1.5.0`, or restore the backup you took above.
The previous .env is at .env.bak.20260801T090000Z.

/health never answered. Same as for install, including the public-URL trap: exit 1, nothing rolled back, and the docker compose logs migrate / logs app lines to read.

One request layer, shared with the MCP server

tripl and the MCP server are two front ends over one instance, and they now share more than an HTTP client. Every REST path, query parameter and response projection either surface uses is defined once, in tripl_cli.api, which tripl-mcp imports. Contract tests in both packages fail the build if a path literal appears anywhere else.

That has consequences you can rely on:

• tripl scans list and the MCP list_scans tool return the same trimmed scan-config shape, including the derived dispatchable flag, computed by one function rather than two.
• tripl scans run and the MCP trigger_scan tool post to the same route, and cannot drift apart.
• tripl drifts list and doctor's drifts check spend the same budget with the same round-robin planner, and share one definition of untriaged.
• tripl events list and the MCP list_events tool send the same filters to the same route, and tripl plan fields and get_event_type_fields read the same two endpoints. What differs is the projection: the MCP trims each row to the handful of keys an agent needs, because a model pays for every token on every turn; the CLI passes rows through whole, because a pipe does not.
• Both surfaces resolve --branch / branch_id against the same branch listing, and <scan>, <event-type> and --branch all run through one matcher — exact on the name, then on the id — so no two arguments in this CLI can mean two different kinds of match.
• The job-history read is one builder with four deliberate answers: doctor asks for the maximum, 200, because it is measuring how long a streak has run; watch for 10, because it repeats every ten seconds; scans jobs for 50; and the MCP get_scan_status tool sends no limit at all and takes whatever the server's default is. Four different windows, one place they are spelled.

The practical rule for an operator: if tripl and an agent disagree about what a project contains, it is not a difference in how the two clients ask. Compare key scopes and roles first.

Exit codes

One table for every command. Every code means the same thing whichever one produced it, but not every code is reachable from every command — doctor owns 3, and nothing else ever reaches it.

Code	Meaning
0	doctor: every check passed, or only warned and --strict was not given. status: it completed. watch: the run completed — --duration elapsed. A failed job, a new signal and a failed delivery all still exit 0, because watch reaches no verdict. scans list / drifts list: every read arrived, including a run that legitimately found nothing. scans jobs: the history was read. events list / events show / every plan verb: the read arrived — including a page that stopped at --limit with more behind it, which is reported in the footer and in truncated, not in the exit code. scans run / scans cancel / drifts dismiss / drifts reopen / annotate / docs push: the API accepted the write — or --dry-run resolved everything and sent nothing. For annotate that includes a 200 for a label the API de-duplicated, which created nothing and is reported as such. install: the files are on disk and, unless --no-start, pull and up -d both succeeded and /health answered (or --wait 0 skipped the wait). upgrade: the new tag is pinned and running — or the pin already equalled --to, which runs nothing and is deliberately 0 so a converging provisioning script is not a failing one. check: no finding at error severity — and, with --strict, none at warning severity either. codegen: the files were written — or, with --check, every file on disk already matches. export: the export was written, or printed to stdout without --out.
1	The tool itself broke, or a command other than doctor could not complete a request — unreachable, or the API refused it (a project-scoped key with no --project gets a 403 here, on a perfectly healthy instance). watch reaches it two ways: a startup read it cannot proceed without (the project listing, or a project's scan listing), and a key revoked mid-run, which ends the run after a watch.stopped line carrying reason: "authentication_failed". Every other failed read during a run is a poll.degraded line, not an exit. Three more routes into 1 belong to the object commands: any failed read in a scans list or drifts list fan-out, a scans run whose job came back already failed, and a scans cancel, drifts dismiss, drifts reopen or docs push you declined at the prompt — "the operator said no" must never be readable as "the mutation happened". install and upgrade reach 1 three ways of their own: docker compose pull or up -d exited non-zero, /health did not answer within --wait, or a file could not be written (a read-only directory, or a race with a second tripl install). The events and plan verbs reach 1 the ordinary way and only that way: each reads ONE resource of ONE project, so there is no partial answer to report beside a failure — a refused read is the client's message and exit 1, never an empty table at exit 0. In none of those is anything rolled back — for install the stack is started, and for a failed up -d the new pin is left in place on purpose. Declining the backup gate is also 1. doctor should never exit 1 — it turns every API failure into a finding, so an exit 1 out of doctor is a bug report, not a diagnosis. check is the one command other than doctor that reaches 1 by verdict: at least one finding at error severity, or at warning severity with --strict. It also reaches 1 the ordinary way, when a validate request fails, and then it writes no document; with --json or --format sarif, a document on stdout means the run completed and the findings decided the code. codegen --check also reaches 1 by verdict: a generated file is missing, differs from what the plan produces now, or is stale. codegen and export reach it the ordinary way too, when the plan read fails or a file cannot be written. docs pull reaches it when the export carries a path that would land outside <dir>, and writes nothing; docs push reaches it when the API refuses the import, which then changes nothing.
2	Usage or configuration error: a bad flag, an out-of-range value, no URL, no API key, an unreadable config file. For doctor and status that is always resolved before any socket opens. watch adds two refusals it can only reach after reading the project and scan listings — --scan matching nothing, and more than 24 selected scan configs — so for it the resolution is two rounds of HTTP in, not zero. The scans and drifts verbs add: a bare group with no verb, a missing or repeated --project on a command that acts on one object, a <scan> selector matching nothing or matching two configs, a --snooze-until that is not RFC 3339, a --limit outside 1–200, a --status that is not one of the six, and scans cancel / drifts dismiss / drifts reopen / docs push on a non-TTY without --yes. annotate adds: a --url that is not an absolute http/https URL or is over 500 characters, an --at that is not RFC 3339, a blank or over-long <label>, and --scope-type without --scope-ref or the reverse. The read groups add: a missing or repeated --project (every one of their routes is per project), a --branch or <event-type> selector matching nothing or matching two, a --status or --type outside the API's own enum, an --offset/--limit outside the route's range, a <query> that is blank or over 500 characters, and --branch on plan branches, which has no such flag. docs adds: a pull into a non-empty folder without --force, and a push of a folder with no .md file, a note over 256 KiB or not UTF-8, or more than one import's limits. install and upgrade add: an explicit --url or --api-key, an --app-url that is not a URL, a --version/--to that is not a valid image tag, a --wait outside 0–3600, a --dir that looks like a tripl source checkout, no docker on PATH / no Compose v2 plugin / a daemon that will not answer, a --dir with no stack in it, a refused downgrade, an unorderable tag pair without --yes, and any prompt met on a non-TTY without --yes. check adds: no check configuration, a check configuration that is not valid YAML or names an unknown key or preset, a call entry with no function / pattern / objc_selector, no project from either --project or the file, a --payloads file that is not JSON or NDJSON, and a --branch matching nothing. codegen adds: no check configuration, a codegen block with an unknown key, style or language, a template file that does not exist or does not parse, a type_names value that is not an identifier in one of its languages, no event type with a codegen block, no output directory from either --out or codegen.out, a --model file that is not a codegen_model export, and --model with --branch. export adds: a missing --format, and --json without --out. Either way no JSON is emitted, no write is ever sent, and no file is written.
3	doctor only: at least one check failed — or, with --strict, at least one warned. No other command reaches 3, whatever it observes.
130	Interrupted (Ctrl-C). For doctor and status that is an abandoned run. For watch it is the normal ending: a run without --duration has no other way to stop, so 130 out of watch means "you pressed Ctrl-C", not "something went wrong". A wrapper that treats non-zero as failure needs to know this before it pages somebody.

Exit 1 out of a write is not always "it did not happen"

A declined prompt, a 403 and a 404 all exit 1 without changing anything. But so does a scans run whose job was created and came back failed, and so does a connection that dropped after the request left. When 1 comes out of a mutation, read the message: it names which of the two you got. Re-run tripl scans jobs before you retry.

An unreachable instance therefore exits 3 out of doctor, not 1 — it is a finding, like everything else doctor reads. That is precisely what makes an exit 1 out of doctor a meaningful signal. Every other command exits 1 on an unreachable instance, because none of them turns a failed read into a verdict.

Credentials are required even for the connectivity check

Every command that talks to an instance demands both the URL and the API key before it opens a connection, so a missing key is exit 2 — for doctor that holds even though /health itself needs no key. That keeps "you have not configured a key" cleanly apart from "the instance rejected your key" — two failures that produced the same shrug during the incident.

install and upgrade are outside this rule in both directions: they need neither value, and passing one explicitly is itself exit 2. Their /health poll and their /auth/status read go out unauthenticated, with no Authorization header, because at install time no account exists and therefore no key can.

note

Exit 1 out of install or upgrade never means "nothing happened"

It means the opposite of a declined write. By the time either reaches 1, the files are on disk and — unless the failure was the pull — the containers have been asked to start. A /health timeout in particular is often just a slow first migration or a proxy that is not up yet. Read the message: it names which step failed and which docker compose logs to open. Re-running is safe; that is what idempotence is for.

  env:

  run: uvx tripl doctor --strict

Use --strict in a gate you watch every run, and plain doctor in an unattended cron: a job that goes red over a handful of untriaged schema drifts gets muted, and then nobody sees the failing scan either.

watch belongs in neither. It reaches no verdict, so there is no exit code for a gate to read, and it only ever saw what fell inside its polls. It is the command you run by hand, next to the incident.

warning

An unattended write needs --yes and a second key

scans cancel and drifts dismiss refuse to prompt when stdin is not a terminal, so a cron job or a CI step must pass --yes — otherwise it exits 2 and sends nothing, every time. Such a job also needs a tk_w_ key backed by an editor or owner, which is not the read-only key the examples above export. Do not promote the diagnostic cron's key to write scope so a second job can share it; mint a second key, and treat an exit 2 from the writing job as a configuration alarm rather than a flaky run.

A deploy step that posts a chart marker is the one write that needs no --yes: annotate never prompts. It still needs that second, tk_w_ key — see tripl annotate for a workflow step.

--json

Every command accepts --json, and in every case the human-readable report still happens — on stderr, so stdout carries machine-readable output and nothing else. That includes the confirmation prompt, which is written to stderr precisely so it can never land inside the document.

What lands on stdout differs by command, because a one-shot report and a follow mode are not the same shape:

• Every command except watch puts at most one JSON document, newline terminated, on stdout and nothing else — exactly one whenever the command completed. tripl doctor --json | jq is a promise, not a habit: doctor turns every API failure into a finding, so it emits its document at exit 0 and at exit 3 alike. scans list and drifts list do the same at exit 1 when a read inside their fan-out failed — that is reported in the document, in errors[]. They emit nothing if the run never got that far, which for them means the project selection itself failed.
• A command that could not complete writes NOTHING to stdout. Every exit 2, and every exit 1 that comes from a request the API refused (403, 404, 409, 422), an instance that could not be reached, a payload of the wrong shape, or a confirmation you declined. That covers every documented failure of scans jobs, scans run, scans cancel and drifts dismiss: they raise on the first refusal, so there is no document to emit and the reason is on stderr. tripl scans run --json against a read-only key prints zero bytes on stdout and exits 1. Check the exit code before you parse, and never treat empty stdout as a transient parse error worth retrying — a retried write is not the same thing as a retried read.
• install and upgrade follow the first rule with one useful difference: they emit their document at exit 1 as well as at exit 0, for the three failures that happen after the files are written — a failed pull, a failed up -d, and a /health timeout. Every exit 2 emits nothing, as everywhere else, and so does a file that could not be written, because at that point there is no plan outcome to report. The exit_code is in the document, so a provisioning script reads the reason out of the same object it already parsed.
• watch puts JSON Lines: one object per event, each on its own line, flushed the moment it is produced. There is no enclosing array, no trailing summary document, and no way to know in advance how many lines there will be — the stream ends when the run does. Per-line flushing is a correctness requirement rather than polish: a follow mode that block-buffers into jq shows nothing for minutes, which reads as a hang in the exact situation the command exists for. Use jq -c or any JSON Lines reader, never a whole-stdin parse.

Stability contract

Within one schema_version, for every command:

• Key names are never removed or retyped.
• status / severity values, check ids, finding codes and watch event tokens are never renamed or repurposed.
• New keys, new check ids, new finding codes and new event tokens may appear in any release. Select by id — or, in watch, by event — never by array index and never by position in the stream.
• title, summary and message are prose and may be reworded at any time. generated_at, duration_ms, requests and tool_version vary per run.

Assert on code and evidence — or, in watch, on event and data. Never assert on prose.

schema_version is shared by every command: it is one number for the whole tool, so a consumer branches on command and never on a per-command version. The command values are "doctor", "status", "watch", "scans list", "scans jobs", "scans run", "scans cancel", "drifts list", "drifts dismiss", "install", "upgrade" and "check" — the invocation with its space, so command and what you typed are the same string.

Every document shares the same first six keys: schema_version, tool, tool_version, command, generated_at and duration_ms.

Every document of a command that talks to an instance carries two more before its own payload: requests (how many HTTP requests the run made) and instance (the resolved base URL, where each value came from, and the key scope).

warning

install and upgrade carry neither requests nor instance

Not as null — the keys are absent. There is no configured base URL and no API key for a command that provisions a host, and an empty instance block would let a consumer believe those fields were merely unset rather than inapplicable. Branch on command before you read either key.

Output is written ASCII-escaped, documents and lines alike: a non-ASCII character inside a message reaches stdout as a \uXXXX sequence, which every JSON parser (jq included) decodes back. The examples below show the decoded form — only a raw grep over stdout would see the difference.

Field notes:

• instance.base_url_source / api_key_source are verbatim provenance — "--url", "$TRIPL_BASE_URL", or the config file's path. "Why is it talking to that instance" was a week of the incident.
• instance.api_key_scope is instance, project or unknown. status always reports unknown: it never calls /auth/me.
• summary always carries all four keys, including the zeroes.
• checks always has exactly six entries, in the documented order.
• skip_reason is non-null if and only if status == "skip".
• exit_code echoes what the shell saw, so a consumer reading only the document knows the verdict.

Same envelope, with command: "status", instance.api_key_scope always "unknown", and a projects array in place of status / exit_code / summary / checks:

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "status",
  "generated_at": "2026-07-31T19:08:09Z",
  "duration_ms": 15,
  "requests": 2,
  "instance": {
    "base_url": "https://tripl.example.com",
    "base_url_source": "$TRIPL_BASE_URL",
    "api_key_source": "$TRIPL_API_KEY",
    "api_key_scope": "unknown"
  },
  "projects": [
    {
      "slug": "mobile",
      "name": "Mobile",
      "is_demo": false,
      "events": { "total": 98, "active": 95, "event_types": 6 },
      "scans": { "total": 2, "failing": 1 },
      "signals": { "significant_open": 3 },
      "monitors": { "firing": 1 },
      "coverage": { "days": 7, "pct": 91.4, "matched": 388, "total": 425 },
      "errors": []
    }
  ]
}

coverage is null when the coverage read failed, and the reason appears in that project's errors array as {"section", "status_code", "message"}. A failed section never blanks the row — the counts that did arrive are still the answer.

watch lines

watch --json shares the first four keys with the documents above and then diverges. There is no generated_at / duration_ms / requests block, because those three describe a run that has already ended, and instance moves down into watch.started's data. Every line carries every key, without exception — a consumer never has to test for presence at the top level.

Key	Type	Meaning
schema_version	int	The same number the doctor and status documents carry.
tool	string	Always "tripl".
tool_version	string	The CLI version. Varies per release.
command	string	Always "watch".
stream	string	"meta", "event" or "diagnostic" — see below. Derived from event, so the two can never disagree.
seq	int	Monotonic from 1 within one run, never reused. A gap means the stream was truncated, and sorting by it undoes whatever a log shipper did to the order.
time	string	When watch observed the change — RFC 3339, UTC, second precision, literal Z. Not when it happened: every domain timestamp is a separately named field inside data.
event	string	The token. This is the contract — see Event tokens for the vocabulary.
project	string or null	Project slug. null on the meta lines, which are about the run rather than about a project.
target	object or null	{"kind", "id", "name"}, the same shape a doctor finding uses. null when the line is not about one object.
message	string	Prose: the human line without its timestamp and token. May be reworded in any release.
data	object	The payload, under the backend's own field names. A key the API did not return at all is absent; a key it returned as null is null. The distinction is deliberate — a metrics_collection job has no replay counters and watch does not invent them, so replay_chunks_total is missing rather than 0.

stream exists so that a consumer can count the right things. Three values, and the split is load-bearing: an incident count must not include the CLI's own transport trouble, and "how much of the window was watch blind for" has to stay answerable.

stream	Tokens	What it is
meta	watch.started, watch.stopped	The run's own frame: what was followed, and how it ended.
event	every job.*, signal.* and delivery.* token	What happened on the instance.
diagnostic	poll.degraded, poll.recovered	What watch could not see. Never an instance event.

One real line of each class, pretty-printed here; on the wire each is a single line.

meta — the first line of every run, and the one that records what the run was actually configured to do:

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "watch",
  "stream": "meta",
  "seq": 1,
  "time": "2026-07-31T19:10:41Z",
  "event": "watch.started",
  "project": null,
  "target": null,
  "message": "1 project, 1 scan config, poll 10s.",
  "data": {
    "instance": {
      "base_url": "https://tripl.example.com",
      "base_url_source": "$TRIPL_BASE_URL",
      "api_key_source": "$TRIPL_API_KEY",
      "api_key_scope": "unknown"
    },
    "projects": ["prod"],
    "interval_seconds": 10.0,
    "duration_seconds": null,
    "stall_after_seconds": 120.0,
    "jobs_limit": 10,
    "deliveries_limit": 20,
    "slow_stream_min_seconds": 30.0,
    "requests_per_fast_tick": 1,
    "requests_per_slow_tick": 4,
    "baseline": {
      "running_jobs": 1,
      "pending_jobs": 0,
      "open_signals": 0,
      "significant_open_signals": 0,
      "failed_deliveries": 0
    }
  }
}

api_key_scope is "unknown" here for the same reason it is in the status document: watch does not read /auth/me, and saying "unknown" is cheaper and more honest than a guess. baseline is the preamble's counts — the state that was already true at attach time and is therefore never re-emitted as events.

The last line of every run is watch.stopped, also meta. Its data carries reason ("interrupted", "duration_elapsed" or "authentication_failed"), elapsed_seconds, ticks, requests, and counts — a tally of every token emitted during the run, which never counts the stopped line itself.

event — the line the incident needed, a replay advancing one chunk:

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "watch",
  "stream": "event",
  "seq": 2,
  "time": "2026-07-31T19:10:51Z",
  "event": "job.progress",
  "project": "prod",
  "target": { "kind": "scan_job", "id": "job-91c2", "name": "nightly replay" },
  "message": "'nightly replay' job job-91c2 chunk 4 of 18 (22.2%) collecting 2026-07-05T00:00:00Z..2026-07-06T00:00:00Z, 2m elapsed.",
  "data": {
    "scan_config_id": "scan-1",
    "scan_name": "nightly replay",
    "status": "running",
    "error_message": null,
    "mode": "metrics_replay",
    "replay_progress_phase": "collecting",
    "replay_chunks_total": 18,
    "replay_chunks_completed": 4,
    "replay_progress_percent": 22.2,
    "replay_current_chunk_index": 4,
    "replay_current_chunk_from": "2026-07-05T00:00:00+00:00",
    "replay_current_chunk_to": "2026-07-06T00:00:00+00:00",
    "replay_chunk_interval": "1d",
    "time_from": "2026-07-01T00:00:00+00:00",
    "time_to": "2026-07-31T00:00:00+00:00",
    "created_at": "2026-07-31T19:08:41Z",
    "started_at": "2026-07-31T19:08:41Z",
    "completed_at": null,
    "updated_at": "2026-07-31T19:10:51Z",
    "elapsed_seconds": 130
  }
}

replay_chunks_completed, replay_progress_phase and the rest are the worker's own key names, unrenamed on purpose: the same string is greppable in the backend's replay task and in this output, so there is no second spelling to drift. Two fields are watch's own rather than the job response's: elapsed_seconds, the age of the job at time, and scan_name, resolved from the scan listing so a consumer does not need a second lookup to name the config. target.name carries the same name.

note

Timestamps inside data are verbatim, and not all of them match time

The envelope's time is normalized by the CLI. Everything inside data is copied exactly as the API returned it and is never reformatted, which is why the job's own started_at ends in Z (it comes from the response model) while the replay block's replay_current_chunk_from ends in +00:00 (it comes from the worker's result_summary). Parse these values; do not string-compare them, and do not assume one spelling.

diagnostic — a read that did not come back. This line is why a non-200 can never be mistaken for an empty result:

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "watch",
  "stream": "diagnostic",
  "seq": 7,
  "time": "2026-07-31T19:10:51Z",
  "event": "poll.degraded",
  "project": "prod",
  "target": null,
  "message": "signals read failed: HTTP 500 on /projects/{slug}/anomalies/signals. Signal lines are suspended until it recovers - no signal lines does NOT mean no signals.",
  "data": {
    "section": "signals",
    "path": "/projects/{slug}/anomalies/signals",
    "status_code": 500,
    "error": "HTTP 500",
    "consecutive_failures": 1,
    "target": "prod"
  }
}

section, path, status_code and error are deliberately the key names doctor uses for endpoint_unexpected_status, so an extractor written for one works on the other unchanged. Note that data.target on this line is the stream's reference — a project slug, or slug/scan_config_id for the jobs section — and is unrelated to the envelope's target, which stays null on every diagnostic line.

poll.degraded has a second shape, for a full window in which every row was new: the same keys, with status_code and error null and consecutive_failures 0, plus "window_full": true and "window" holding the limit that was hit. Nothing failed in that case — older rows may simply have been pushed out between polls.

poll.recovered closes a poll.degraded run, and its data is section, path, failed_polls, gap_seconds and events_during_gap — the last being the number that tells you whether the quiet stretch was watch being blind or the instance being calm.

scans list document

The shared envelope plus a projects array. Each project carries slug, name, is_demo, scans and errors, and all five are always present — scans is [] when the listing failed, and the errors entry beside it is what says so.

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "scans list",
  "generated_at": "2026-07-31T19:12:51Z",
  "duration_ms": 31,
  "requests": 3,
  "instance": {
    "base_url": "https://tripl.example.com",
    "base_url_source": "$TRIPL_BASE_URL",
    "api_key_source": "$TRIPL_API_KEY",
    "api_key_scope": "unknown"
  },
  "projects": [
    {
      "slug": "prod",
      "name": "Prod",
      "is_demo": false,
      "scans": [
        {
          "id": "scan-1",
          "name": "prod events",
          "interval": "1h",
          "time_column": "event_time",
          "data_source_id": "ds-1",
          "event_type_id": "et-1",
          "event_type_column": "event_name",
          "event_name_format": "snake_case",
          "replay_chunk_interval": "1d",
          "scan_lookback_hours": 24,
          "created_at": "2026-06-01T09:14:00Z",
          "updated_at": "2026-07-30T11:02:00Z",
          "dispatchable": true
        }
      ],
      "errors": []
    },
    {
      "slug": "mobile",
      "name": "Mobile",
      "is_demo": false,
      "scans": [],
      "errors": [
        {
          "section": "scans",
          "endpoint": "/projects/mobile/scans",
          "status_code": 403,
          "message": "Forbidden (403): the API key lacks the required scope (tk_r_ keys cannot write), is scoped to a different project, or the backing user role is insufficient. API detail: Not authorized for project"
        }
      ]
    }
  ]
}

Those twelve keys plus dispatchable are the whole projection — the same one the MCP list_scans tool returns. A key the API did not return is absent rather than null, so test for presence before reading scan_lookback_hours on an old instance. dispatchable is the CLI's own field, not the API's: it is interval and time_column both being set, which is the dispatcher's own selection predicate.

errors[] entries are {section, endpoint, status_code, message}, and endpoint is the concrete path that failed — not its template — because an operator listing six projects cannot act on a message that does not say which one. status_code is null when nothing answered at all.

scans jobs document

project, scan ({id, name}), the limit that was requested, and jobs — ScanJobResponse rows verbatim, newest first. Nothing is trimmed here: result_summary carries the replay chunk counters watch reads, and error_message is the whole answer to why did it fail.

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "scans jobs",
  "generated_at": "2026-07-31T19:12:51Z",
  "duration_ms": 31,
  "requests": 2,
  "instance": {
    "base_url": "https://tripl.example.com",
    "base_url_source": "$TRIPL_BASE_URL",
    "api_key_source": "$TRIPL_API_KEY",
    "api_key_scope": "unknown"
  },
  "project": "prod",
  "scan": { "id": "scan-1", "name": "prod events" },
  "limit": 3,
  "jobs": [
    {
      "id": "job-91c2",
      "status": "running",
      "created_at": "2026-07-31T19:08:41Z",
      "completed_at": null,
      "error_message": null
    }
  ]
}

limit is what was asked for. Compare it against jobs | length before concluding a config has no older history.

drifts list document

status_filter echoes the --status that produced the list, and each project reports its own budget spend:

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "drifts list",
  "generated_at": "2026-07-31T19:12:51Z",
  "duration_ms": 31,
  "requests": 3,
  "instance": {
    "base_url": "https://tripl.example.com",
    "base_url_source": "$TRIPL_BASE_URL",
    "api_key_source": "$TRIPL_API_KEY",
    "api_key_scope": "unknown"
  },
  "status_filter": "all",
  "projects": [
    {
      "slug": "prod",
      "name": "Prod",
      "is_demo": false,
      "event_types_total": 17,
      "event_types_examined": 17,
      "truncated": false,
      "drifts": [
        {
          "id": "drift-1",
          "field_name": "cart_value",
          "drift_type": "type_changed",
          "status": "open",
          "detected_at": "2026-07-28T04:10:00Z",
          "event_type_name": "app.screen_view",
          "untriaged": true
        }
      ],
      "errors": [
        {
          "section": "drifts",
          "endpoint": "/projects/prod/event-types/et-9/drifts",
          "status_code": 404,
          "message": "Not found (404): Event type not found"
        }
      ]
    },
    {
      "slug": "mobile",
      "name": "Mobile",
      "is_demo": false,
      "event_types_total": 240,
      "event_types_examined": 183,
      "truncated": true,
      "drifts": [],
      "errors": []
    }
  ]
}

A drift row is the API's SchemaDriftResponse verbatim — all fourteen fields, because resolved_by and resolution_note are how an accidental field deletion gets traced — plus the two facts the API cannot carry: event_type_name, resolved from the event-type listing so a consumer needs no second lookup, and untriaged, this run's evaluation of open, or snoozed past its snooze.

event_types_examined and truncated are per project, deliberately: the budget is spent round-robin, so one instance-wide ratio would name no project, and "we did not look there" is only useful when it says where.

warning

"drifts": [] is not "no drifts"

Not on its own. It means "no drifts matching status_filter among the event_types_examined event types whose reads succeeded". Check errors, compare event_types_examined with event_types_total, and check the process exit code. The human output prints all three on one screen for exactly this reason.

events and plan documents

The seven read verbs share one document shape. items holds the rows whichever verb produced them — including events show, which puts its single event there rather than inventing a second shape for the one command that returns exactly one thing. jq '.items[]' therefore works across the whole group.

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "events list",
  "generated_at": "2026-08-01T09:12:51Z",
  "duration_ms": 24,
  "requests": 1,
  "instance": {
    "base_url": "https://tripl.example.com",
    "base_url_source": "$TRIPL_BASE_URL",
    "api_key_source": "$TRIPL_API_KEY",
    "api_key_scope": "unknown"
  },
  "project": "prod",
  "branch": null,
  "kind": "event",
  "total": 412,
  "offset": 0,
  "limit": 2,
  "truncated": true,
  "meta": {},
  "items": [
    {
      "id": "evt-1",
      "name": "app.screen_view.viewed",
      "status": "live",
      "event_type_id": "et-1",
      "last_seen_at": "2026-07-31T19:00:00Z",
      "drift_count": 2,
      "tags": [{ "id": "tag-checkout", "name": "checkout" }],
      "field_values": [
        { "id": "fv-1", "field_definition_id": "fd-1", "value": "checkout" }
      ],
      "meta_values": []
    }
  ]
}

Every key above is present on all seven, so a consumer never tests for one before reading it.

Key	Meaning
project	The slug that was read. Always exactly one.
branch	{id, name} when --branch was passed, null when it was not. null means "no branch was named", not "this is main": --branch main reads the live plan and still carries main's own id and name, so branch on whether the flag was given rather than on null — see --branch.
kind	What one member of items is: event, event_type, field, variable, branch or search_result. Branch on this, never on command's wording.
total	The count the API reported before paging, or null where the route reports none.
offset / limit	What was requested, or null where the route takes no such parameter. plan search has no offset; plan types, plan fields and plan branches page nothing at all.
truncated	Whether rows were left behind. The route's own answer where it reports one — plan search does, and it is exact; otherwise whether total exceeds offset plus the rows returned; and where a route reports neither, whether the page filled. Derived here so nobody has to do that arithmetic twice.
meta	Facts the route reported about the answer rather than about a row. {} on six of the seven; {"semantic_used": bool} on plan search.
items	The API's own objects, verbatim.

warning

"truncated": true is not an error, and "items": [] is not "none exist"

Truncation is rows left behind: a full page with more behind it, or a route that says outright it dropped ranked hits. The exit code stays 0, because nothing failed — the CLI asked for a page and got one. A loop that reads items and stops without checking truncated will silently process the first limit rows of a catalog forever.

"items": [] means "nothing matched these filters on this branch". A failed read never reaches this document at all: these verbs read one resource of one project, so a refusal is exit 1 with the client's message and no JSON.

Rows are verbatim, and that is a decision

scans list trims its rows because base_query is kilobytes of free-text SQL that answers no operational question. Nothing here is trimmed, for the opposite reason: a CLI writes to a pipe, where a dropped field is one you have to go and fetch again with a second command.

The MCP server does trim the same payloads — list_events returns nine keys per event, not thirty. That is a statement about a model's context budget, where every token is paid for on every turn, and it stays with that consumer. If these documents ever start trimming, it is a contract change and it will be announced as one.

Mutation documents

scans run, scans cancel, drifts dismiss, drifts reopen, annotate and docs push share one shape. Every key is present on every one of them, null where it does not apply, so a consumer never has to test for existence before reading — the same rule the doctor summary follows.

{
  "schema_version": 1,
  "tool": "tripl",
  "tool_version": "0.1.0",
  "command": "drifts dismiss",
  "generated_at": "2026-07-31T19:12:51Z",
  "duration_ms": 31,
  "requests": 1,
  "instance": {
    "base_url": "https://tripl.example.com",
    "base_url_source": "$TRIPL_BASE_URL",
    "api_key_source": "$TRIPL_API_KEY",
    "api_key_scope": "unknown"
  },
  "dry_run": false,
  "request": {
    "method": "POST",
    "path": "/projects/prod/event-types/drifts/drift-1/actions",
    "params": {},
    "body": {
      "action": "snooze",
      "note": "waiting on the mobile release",
      "snoozed_until": "2026-08-04T00:00:00Z"
    }
  },
  "project": "prod",
  "scan": null,
  "job_id": null,
  "drift_id": "drift-1",
  "action": "snooze",
  "deduplicated": null,
  "result": {
    "id": "drift-1",
    "field_name": "cart_value",
    "drift_type": "type_changed",
    "status": "snoozed"
  }
}

Key	Meaning
dry_run	true when nothing was sent.
request	What was sent, or under --dry-run what would be. Exactly method, path, params, body — never headers, never the API key. params drops nulls, so it is what would go on the wire.
project	The single --project slug.
scan	{id, name} for the two scans verbs, else null.
job_id	scans cancel only, else null.
drift_id	drifts dismiss and drifts reopen only, else null.
action	"false_positive" or "snooze" for drifts dismiss, else null.
deduplicated	annotate only: false when the API created the annotation (201), true when it returned one that already existed (200). null for every other verb and under --dry-run.
result	The API's response object, verbatim. null under --dry-run, always — nothing was sent, so there is no result, and the absence is the statement.

For scans run the same document carries "command": "scans run", "scan": {"id": ..., "name": ...}, "action": null, and result is the created ScanJobResponse. Read result.status before you call it a success: a 201 with "status": "failed" is what a broker outage looks like, and it is the reason that case exits 1.

For annotate it carries "command": "annotate", scan, job_id, drift_id and action all null, request.body with "source": "api", and result is the ChartAnnotationResponse. Read deduplicated before you report "annotation created": a retried job gets true, and the result it holds is the earlier annotation.

check document

One document per run, in either mode. results holds one row per call site (static mode) or captured event (payload mode), the passing ones included, so a consumer can count coverage as well as failures. summary counts the rows by status the way the exit code does.

Key	Meaning
project	The project slug checked against.
branch	{id, name} when a branch was named (by --branch or the check configuration), null when it was not — the same rule as the events and plan documents.
mode	"static" or "payloads".
strict	Whether --strict was given.
config	The path of the check configuration that was read (as given to --check-config, or the absolute path of the one found), or null when none was (payload mode without a config file).
files_scanned	How many source files the static scan read. 0 in payload mode.
summary	checked (every row), and the rows by status: ok, warnings, errors, dynamic.
exit_code	The process exit code: 1 when errors is non-zero, or with strict when warnings is; else 0.
results[].status	ok, warning or error (the worst finding's severity), or dynamic: nothing about the call was readable, so nothing was sent for it. With --strict a dynamic call, and an otherwise clean row with an info finding, becomes a warning.
results[].location	path, line, column, end_line, end_column. In static mode, the call's span, with 1-based lines and columns and path relative to the scan root (the check configuration's root, by default the directory that holds .tripl/). In payload mode, path is the --payloads argument as typed, relative to the working directory the command ran in (<stdin> for -), line is the NDJSON line (or 1 for an event in a JSON array), and column, end_line and end_column are null.
results[].snippet	Static mode: the callee or selector as matched, for example Analytics.shared.log. Payload mode: event N (the 1-based position) for an event in a JSON array, else "".
results[].event_type / name	The plan event type name and the event name as read from the call or payload; either may be null.
results[].fields	Field name to value, as sent for validation. A null value is dynamic, not missing.
results[].properties	The literal property dictionary, or null when there was none.
results[].complete	true for a payload (a whole event, so a missing required field is an error), false for a call site.
results[].dynamic	The targets whose value was only known at runtime: name or field names.
results[].event_id / identity	The plan event the item resolved to, and the identity it was matched by, with ${…} holes for parts only known at runtime. event_id is null when nothing matched; both are null for a row that was never sent.
results[].findings[]	code, severity (error, warning or info), field (the plan field concerned, or null) and a prose message. Select on code: the codes are the validator's plus the CLI's own dynamic_value (with --strict), oversize_value (a value over the validator's size limits, sent as null) and no_verdict.

With --format sarif stdout carries a SARIF 2.1.0 log instead, and none of the keys above: each finding is a result whose ruleId is its code.

Key	Meaning
directory	Always absolute, whatever --dir you typed.
app_base_url	The normalised --app-url. Also the origin health was polled at.
image / version	What was pinned in .env.
dry_run	true when nothing was written and nothing was run.
files[]	One entry per planned file, in the order they are applied. path is relative to directory; action is one of create, replace, append, unchanged, kept; mode is the mode asked for, as a string ("0600" — an integer 384 is not a file mode anybody reads); note explains a kept ("differs from the version this CLI ships", or "complete" for a .env that already had every key); keys holds variable names and never values.
secrets_generated	The names of the secrets this run produced. Empty on a re-run that left .env alone. There is a test asserting no generated value appears anywhere in this document.
commands[]	Every planned command with argv, cwd, the env overlay, and returncode. A command that was never reached carries "returncode": null rather than being omitted — "the pull failed so up -d never ran" is exactly the fact you need, and an absent entry would read as "it ran and we lost the code". Empty under --no-start. Compose's own output is not here by construction; see above.
health	null when the run never got there (including --dry-run). Otherwise status is ok, timeout or skipped; last_error carries the last probe's own message ("HTTP 502", "ConnectError") and is null when it succeeded or was skipped.
bootstrap	The /auth/status body verbatim — has_users, registration_enabled, email_configured, deployment_mode, email_verification_required — or null if it could not be read. A hosted instance always reports has_users: true, so the next steps never offer it a first-owner account. That failure never changes the exit code; it only changes the wording of the next steps.
exit_code	The process exit code, in the document.

commands, health, dry_run, directory and exit_code mean exactly what they mean for install. The rest:

Key	Meaning
current_version	The TRIPL_VERSION read out of .env before anything ran.
target_version	Your --to.
ordering	same, upgrade, downgrade or unknown — the comparison above. A downgrade never reaches a document; it is exit 2.
backup_command	The multi-line pg_dump block that was printed, verbatim, so a wrapper can show or log the same text. It was not run.
env_backup	The basename of the .env copy taken before the pin was moved, or null if .env was never rewritten. Non-null is the fact a rollback needs; it sits next to .env in directory.

Note the env overlay on the pull and not on the up: that asymmetry is the whole ordering rule, and it is visible in the document.
