Prove It Ship Gate

Auto-trigger when claiming a feature, worker, or integration is done, shipped, or working and the Goal includes live side effects (Linear tickets, deploy, live mine, external APIs). Unit/fixture tests and UI registration alone are not enough — route to prove-it for live evidence before treating the claim as settled.

File contents

prove-it-ship-gate

Thin routing skill for ship/done claims with live side effects.

Follow Invoker or a locally installed prove-it for the shared evidence rule. This file only adds the ship/done auto-route; it does not replace prove-it.

Rule

When the work under claim has live side effects:

Fixture ≠ live. Unit tests, mocked fixtures, and UI registration Visual Proof do not prove the live path ran.
Before stating done / shipped / working: show live evidence in the same turn, or prefix the claim with UNVERIFIED: live path.
Do not frame UI Visual Proof (for example worker registration in a settings panel) as product e2e of the live side effect.

Mechanical enforcement

The same-turn check is a Stop hook, engine/hooks/prove-it-ship-gate/ (installed by install.sh). It blocks the turn when a done/shipped/live claim sits near a live-side-effect noun with no chaseable evidence, no live command this turn, and no UNVERIFIED: live path prefix. This file keeps the judgment half: deciding whether the work really has live side effects.

Incident

Invoker PRs #10553–#10558 published cross-repo-research after unit + fixture + UI only; the user forced a live Linear e2e and a reflect afterward.

If the claim isn't done/shipped but repeated failed attempts on one problem within a live session, that's narrow-the-scope, not this skill.

If a grading/validation board came back FAIL or NEEDS_WORK, or the user says "/thrash", that's thrash-reflect-automate.
