feat(cli): let trigger carry a payload - #312
Conversation
`agentworkforce trigger` could only fire blanks. The endpoint behind it accepts
any JSON object and hands it to the handler as the event payload — that is the
whole point of an app-triggered agent — but the CLI sent no body, so every
manual run looked exactly like a schedule firing.
That is not a cosmetic gap. Verifying app-signal's Slack write after narrowing
its mount was impossible from the CLI: the bare trigger took the agent's
contentless path, which by design stays silent. Proving the payload path needed
a hand-rolled curl with a separately minted token, and the repo already carries
`scripts/trigger-agent.mjs` for exactly this reason.
agentworkforce trigger app-signal '{"accountId":"acme","reason":"usage_spike"}'
agentworkforce trigger app-signal --payload-file ./signal.json
echo '{"accountId":"acme"}' | agentworkforce trigger app-signal --payload-file -
Also adds `--idempotency-key`, which the endpoint already honours: retrying with
the same key returns the original run instead of starting a second one.
Details worth knowing:
- A body-less POST and a `{}` body are NOT the same to cloud. The first is a
contentless fire; the second is an app trigger carrying an empty object.
Content-Type and body are attached only when a payload exists, never
defaulted, and `buildTriggerRequest` is split out so a test pins that.
- The payload must be a JSON object. Cloud wraps it as
`{source:'app.trigger', payload:<body>}` and handlers read named fields off
it, so an array or scalar would earn a 202 and then a run that does nothing.
Rejected before the request, with the reason.
- Parsing stays synchronous and side-effect free; `--payload-file` reading is
deferred to `resolvePayload`, so argument handling remains testable without a
filesystem or stdin.
- A trailing `{...}` positional is treated as the payload. Unambiguous: no agent
id, deployed name, persona slug or persona id starts with a brace, and a
non-JSON extra positional still errors as before.

📝 WalkthroughWalkthroughThe trigger CLI now accepts inline JSON, payload files, stdin payloads, and idempotency keys. It defers payload I/O, validates JSON objects, and builds requests with optional JSON bodies and headers. Tests cover parsing, resolution, validation, request construction, and usage text. ChangesTrigger payload handling
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The CLI's equals-form --payload-file currently accepts dash-prefixed values such as --json and may try to read them as filenames instead of rejecting invalid input; this is a bounded command-line correctness issue, so the PR is mergeable with owner follow-up to align both payload-file forms and add the regression test.

This new syntax is documented only by trigger --help; the primary agentworkforce --help output still enumerates only the old trigger flags in packages/cli/src/cli-impl.ts:274-282, and the published command synopsis in packages/cli/README.md:17 is also stale. Users consulting either primary entry point are therefore told that trigger cannot carry a payload or idempotency key, undermining discoverability of this feature; update those copies or derive them from this usage definition.
Useful? React with 👍 / 👎.

… top help Review caught both. `--payload-file=--json` skipped the path check the space-separated form applies, so it would have gone looking for a file literally named `--json`. The equals branch now uses the same `expectPathValue`, and a test pins both spellings — including that `--payload-file=-` still means stdin, which is the reason that guard cannot simply be "reject anything starting with a dash". The payload syntax was documented only under `trigger --help`, while the top-level `agentworkforce --help` still listed the old flag set. Someone reading the main help would conclude the CLI cannot send a payload, which is exactly the belief this change set exists to correct. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
