Overview / Motivation
Auto-filed by /daily 2026-07-27 problem sweep (transcript mining, 44 in-window transcripts). Session 4d10421c (#1723), 2026-07-27T14:52Z.
Goal
Make the code-reviewer's verdict post durable and self-verified: --file channel + a mandatory read-back before the agent returns.
Workflow gap
- Bug observed: the reviewer's return claimed its
epm:code-reviewmarker was posted; no marker existed on events.jsonl and the durable verdict file/tmp/code-review-1723.mddid not exist either. The orchestrator burned 3 probe calls + a full duplicate reviewer round (~9 min). - Why it is a workflow gap: the agent spec's canonical post recipe is
post-marker ... --note "$(cat /tmp/code-review-<N>.md)"— the argv-prose channel CLAUDE.md #1722 already deprecates for git-verb-bearing bodies (a review body quotes diff text/git verbs, a plausible silent-block cause) — and no read-back-verify duty exists, so 'posted' can be claimed unverified. - Confidence (emitter): medium
- verified-at-filing:
grep -n 'note \"\$(cat' .claude/agents/code-reviewer.md-> L37 (--version <revision_round> --note "$(cat /tmp/code-review-<N>.md)"), run at compose time 2026-07-28T06:5xZ; nolatest-markerread-back duty near it (sed 33-60 inspected).
Proposed change (candidate diff sketch — refine in planning)
In .claude/agents/code-reviewer.md (~L33-40): (a) change the post recipe to post-marker <N> epm:code-review --file /tmp/code-review-<N>.md; (b) add a final duty: read back task.py latest-marker <N> --prefix epm:code-review and confirm the just-posted version BEFORE returning — never claim 'posted' unverified.
Scope / surfaces
- Primary target:
.claude/agents/code-reviewer.md - Check the codex twin composer + Step 5b SKILL.md text for the same recipe string (grep before editing).
Constraints / invariants
- Workflow-surface only — never experiment code,
configs/, ortasks/. scripts/workflow_lint.pyno-flags run +--check-askspass on touched files; ruff passes where applicable.- This session runs under a
workflow_fix_target:Provenance line — it MUST NOT auto-route its own subagents' workflow-fix candidates (recursion guard).
