From 97cb8006593f859b90f8da1cd62101fb857e766f Mon Sep 17 00:00:00 2001 From: Edbert Chan Date: Thu, 24 Sep 2026 00:55:33 +0800 Subject: [PATCH 01/20] pr-schema-gate: find the validator in catstack, report UNCHECKED when a repo has none Scope now comes from the .git boundary, not scripts/create-pr.mjs. The validator is scripts/validate-pr-body.mjs, then engine/skills/draft-pr/scripts/validate-pr-body.mjs. A PR-publishing command in a git repo with neither reports UNCHECKED instead of staying silent.

charset=UTF-8 Content-Transfer-Encoding: 8bit * wrong-check-reflect: one shot per reply, and scope the reflect scan to the turn Two independent lockouts kept this hook from speaking on Claude Code. One: `already_prompted` was keyed on the transcript path, so the Stop of the reply BEFORE a correction spent the session's single shot. The correction itself then hit an already-prompted key. The key is now the transcript path plus a hash of the reply text, so each distinct reply gets its own chance and the same reply is still judged only once. Two: `user_already_asked_reflect` scanned the whole transcript. One `/reflect` typed at the start of a session switched the detector off for every later reply. The scan is now scoped to the user messages of the turn that produced the reply being judged, which is the case the skip was written for. An unreadable transcript now says so on stderr instead of silently reading as "the user did not ask". The harness-parity test asserts the same reply is judged under both `Stop` and `stop`. It passes before this change too: this hook compares no event name anywhere, so event-name case cannot be what split its hits by harness. The test pins that, rather than leaving the parity unstated.

A sentence ABOUT the hook switched the hook off. `"Claim I made was wrong" is a trigger for /reflect` describes when the detector fires; it asks for nothing, and nothing is in flight to avoid duplicating. It now matches the harness's own record of an invocation, the `/reflect` envelope.

The turn window anchors on the newest real user row, so the first tool call of a turn became the anchor: a `/reflect` typed at the top of the turn fell outside the window and the hook nagged for a reflect already asked for. A tool result quoting the word the other way round could also suppress the nudge. `_is_tool_result_line` reads the record the harness does write -- a `tool_result` content block, or the `toolUseResult` field beside the message -- the same way `engine/hooks/agent-relay-attribution/detect.py` does, and `_is_meta_line` now files those rows under the harness rather than the person. Two tests: a tool result mid-turn no longer hides the turn's own `/reflect`, and `/reflect` printed inside a grep result does not count as a request. Both fail without the detect.py change.

That text is narrower: it fires on "UI/layout work" or on a test the user asked for. Work that was neither -- an agent running a CI Playwright shard on the user's own Mac and opening Electron windows on their desktop -- had no trigger left, and a "Shipped" claim went out with no end-to-end run behind it. Restore the gate in a form that names the surface rather than the kind of work: any surface the repo's fixtures cannot stand in for, including the user's own machine, session, or screen. Add the clause that failed hardest in the incident -- "I chose not to run it" is not a blocker -- and make "admit what was not exercised" an enumeration against the done-gate instead of a recollection. The full text and the end-to-end argument it rests on (Saltzer, Reed & Clark, ACM TOCS 2(4) 1984) live in the reference; SKILL.md keeps every trigger condition, because a pointer narrower than the text it replaces is exactly what failed here. Four tests pin the surfaces, the not-a-blocker clause, the enumeration, and the citation.

Two defects stack, and either one alone keeps them silent. The live-noun list held only external services, so "the popups are stopped on your machine" matched nothing and the gate returned before it ever looked at evidence. Add the surfaces an agent can disturb without leaving the desk: the user's machine, Mac, laptop, desktop, screen or session, plus end-to-end, e2e, Playwright, Electron and popup. The evidence scan then accepted any URL, so the two links to this change's own pull requests discharged the gate -- while the gate's own block text already said the PR number of this change does not prove the live path ran. Blank a pull-request link's span before the scan, so the two agree. Only that span: a sha, an exit code, or a fenced block beside the link still counts, and an Actions-run URL is still a receipt. Both incident messages are fixtures, verbatim. The negatives keep the near neighbours silent: a mention with no claim, a link beside a real sha, an Actions-run URL, and the follow-up message that pasted the suite's own output.

Listing bare `end-to-end` and `e2e` as live nouns broke that, because `working end-to-end` and `confirmed end-to-end` are already claim phrases -- so the claim always sat on top of a live noun and the two parts collapsed into one. "Done. The parser now works end-to-end" was blocked for showing no live evidence it never needed. Drop the bare idiom. It says how a check ran, not where. The surface in the incident was the desktop the windows opened on, and `your machine`, `your Mac`, playwright, electron and popup already name it -- every incident fixture still fires on one of those, and `end to end on your laptop` still fires on the laptop. Two tests pin it: the idiom-only messages stay silent, and no claim phrase may consist entirely of live nouns.

The two blocks explaining why bare "end-to-end" and "e2e" are not live nouns went in as plain comments, so the test job's last step failed with "10 new comment line(s)". Move the detect.py rationale into the module docstring, which the detector skips by design (engine/hooks/no-comments/detect.py), and drop the test-file comment: test_silent_when_only_the_idiom_names_the_surface already carries the same reasoning in its own docstring. No behaviour change -- LIVE_NOUN_RE and every fixture are untouched.

That is the exact wording the block message, the README, and the skill all use, which meant the gate stayed silent on a done-claim phrased the way the gate itself recommends: same sentence, one extra word, opposite verdict. The noun scan now accepts one optional qualifier (own, real, actual, personal, local) after the possessive. Tests cover each qualifier and assert the block message's own phrasing trips the scan, so the gate can never again describe a surface it cannot detect. * invoker: wf-1790184149094-309/repair — Resolve bot review thread on PR #779 Exit code: 0 --------- Co-authored-by: Edbert Chan Co-authored-by: Claude Opus 5 (1M context) Co-authored-by: CI Bot --- docs/ecosystem.md | 1 + engine/hooks/prove-it-ship-gate/README.md | 59 ++++- engine/hooks/prove-it-ship-gate/detect.py | 39 +++- .../prove-it-ship-gate/tests/test_hooks.py | 213 ++++++++++++++++++ 4 files changed, 299 insertions(+), 13 deletions(-) diff --git a/docs/ecosystem.md b/docs/ecosystem.md index cd74778c..88087bac 100644 --- a/docs/ecosystem.md +++ b/docs/ecosystem.md @@ -81,6 +81,7 @@ again. | `frustration-watchdog` | hook | | `named-verb-guard` | hook | | `plan-discipline` | hook (not always installed) | +| `prove-it-ship-gate` | hook (Stop; blocks a done/shipped claim about a live surface -- an external service, or the user's own machine, session, or screen -- when the message shows no receipt the run itself emitted) | | `pr-schema-gate` | hook (advisory; PreToolUse on shell tools; checks direct PR text writes with the repo's own `scripts/validate-pr-body.mjs` and reminds about the stack follow-up; never blocks) | | `reflect-on-thrash` | hook (off unless `CATSTACK_REFLECT_ENFORCEMENT=1`) | | `scope-lock` | hook (off unless `CATSTACK_REFLECT_ENFORCEMENT=1`; stops every tool after a second scope correction) | diff --git a/engine/hooks/prove-it-ship-gate/README.md b/engine/hooks/prove-it-ship-gate/README.md index f0067907..e69b4a35 100644 --- a/engine/hooks/prove-it-ship-gate/README.md +++ b/engine/hooks/prove-it-ship-gate/README.md @@ -1,12 +1,48 @@ # prove-it-ship-gate Stop hook: when the outgoing message claims done / shipped / deployed / live -about work with a live side effect (Linear, deploy, production host, webhook, -Slack, external API), the same message must carry evidence a reviewer can -chase (URL, sha, ticket or PR id, fenced output, exit code, PID, timestamp), -or a live command must have run this turn (`ssh`, `curl`, `gh api`, -`gh pr view`, `systemctl`, ...), or the claim must carry the literal prefix -`{{CAT-UNVERIFIED: -- cannot verify: }}`.

The hook treats exit 0 alongside an UNCHECKED/SKIPPED/not-installed line as a vacuous pass, so the validator gets no credit for a run that never judged the body. The catstack validator prints exactly such a line for a sub-check it skipped -- "Summary reading grade unchecked: Summary has N words; under 30 the score is too noisy to trust" -- while still accepting the body and exiting 0. Every accepted body with a short Summary was therefore reported unchecked. check_body_file now lifts the vacuous reading when the run states its own verdict on the body (VALIDATOR_PASS_VERDICT_RE, "PR body validation passed"). Only a pass verdict counts, so a "failed" banner beside exit 0 stays unchecked. The scan also reads the whole output rather than the first VALIDATOR_OUTPUT_MAX_LINES: truncation shortens what the agent is shown, never what is judged. Two tests in tests/test_advisory.py drive a stub validator with the catstack shape (skip note on stderr, verdict on stdout, exit 0): one asserts the write is silent, one asserts it clears the pending follow-up. Both fail before this change. test_validator_exit_zero_with_an_unchecked_ line_is_not_clean still passes, so the guard against a validator that really did not run is unchanged.
