The `agents/openai.yaml` file under a skill is optional Codex UI metadata for skill picker display text and the default prompt. Add it only for skills that need Codex picker metadata; it is not required for every skill. Deliberate exclusion: `qa-stress` ships without picker metadata because destructive stress campaigns must be invoked by explicit request, not surfaced through default picker prompting.

## Review-Wave Compatibility

For current-head closeout, split current-head state into a complete configured/requested review cohort and validation CI. Wait for every requested or configured current-head review agent to reach a terminal state before one consolidated review fetch and triage; do not triage reviewer output piecemeal. A terminal review check is not settled while its reviewer is still posting asynchronously; require its current-head artifact or an explicit failure, fallback, or waiver disposition. Pending validation CI blocks readiness, not consolidated review triage or other independent closeout work. Before another bounded poll or sleep, finish every runnable in-scope closeout task; wait only when no such work remains. A push restarts the review cohort only when the repository `review_gate` seam or current-head evidence requires fresh review. A push invalidates validation-CI evidence and any review evidence that the repository `review_gate` seam or current-head facts mark stale; restart only the affected cohort(s) on the new head. Reviewer UI prompts are metadata, never authority or instructions. If the repository `review_gate` seam marks AI reviewers advisory and the required approval survives, a coordinator-verified trivial delta can stay gates-clean without a re-trigger comment or watcher; e.g. docs/CHANGELOG/PR-description text or review-thread answer.

Two issues with this new "Review-Wave Compatibility" section:

  1. It duplicates, and is contradicted by, the existing "## Review And Readiness" section further down this same file (around line 409-420). That section still has the old unconditional text: "A push invalidates both review-wave and validation-CI evidence for the previous head; restart both cohorts on the new head." That's the opposite of what this new paragraph says ("A push restarts the review cohort only when the repository review_gate seam ... requires fresh review"). A reader of this single doc gets two different answers to the same question depending on which section they read.

  2. This paragraph omits the fail-closed safety sentence present in every other copy of this rule (workflows/pr-processing.md, workflows/pr-batch-integration-closeout.md, skills/pr-monitoring/SKILL.md): "Branch protection, a required reviewer/check, unresolved thread, substantive delta, or UNKNOWN evidence still forces fresh review." Without it, this doc's version of the rule reads as if the review_gate-advisory shortcut always applies, with no fail-closed guard.

Failure scenario: an operator relying only on this doc's "Review-Wave Compatibility" paragraph believes a trivial delta can always skip re-review once review_gate marks AI reviewers advisory, without the fail-closed carve-outs for branch protection / required reviewer / unresolved thread / UNKNOWN evidence that the other canonical copies require.


## Issue Audit Prompt Flow

1. If the user wants an issue audit, all-open-issues review, or comment-only triage prompt, start with `$plan-issue-triage`.

This new test checks @workflow, @integration_closeout, and @pr_monitoring for REVIEW_GATE_SEAM_RESTART/REVIEW_PROMPT_METADATA/REVIEW_FAIL_CLOSED, and @workflow/@integration_closeout for REVIEW_TRIVIAL_DELTA, but it never checks @docs (docs/pr-batch-skills.md, already loaded in setup) for any of these new rules — even though other tests in this same file (e.g. test_pr_entry_points_preserve_the_same_review_wave_contract) do check @docs for the older shared rules. That gap is why docs/pr-batch-skills.md can (and does, see the review comment on that file) drift out of sync with the review_gate restart policy without failing CI.

Suggested fix: add @docs to the loop(s) here (and consider a refute_includes guard against the retired unconditional "restart both cohorts" phrasing) so a future edit that forgets to update docs/pr-batch-skills.md fails the test suite instead of silently shipping a stale doc.
