Looks good to me

HIGH: Duplicate of already-open PR #473 (superset, with documented motivation)

PR #473 ("chore: ignore Python bytecode cache artifacts", opened 2026-07-27, still open) already adds a root .gitignore that is a strict superset of this change — it ignores both __pycache__/ and *.pyc, and its description documents the concrete motivating cause (gitlint's local pre-commit env generates gitlint_rules/__pycache__/*.pyc, which was accidentally staged via git add -A in #469, per #473's own body: "Split out from #469 per review feedback there that it was unrelated scope creep"). This PR's diff contains only a single line, __pycache__/, added three days after #473 with no linked issue and a generic one-line summary showing no evidence of checking for prior art. Merging both would create redundant/overlapping commits on the same new file.

Suggestion: Close this PR in favor of #473 (broader, better-justified coverage), or if it must be kept, at minimum add *.pyc to match #473's coverage and note in the description why a second, overlapping PR was opened instead of reviewing/completing #473.

Retro: PR #570 — chore: add .gitignore with __pycache__ exclusion

What happened

PR #570 was a human-created (ralphbean) 1-line .gitignore adding __pycache__/. Three days earlier, PR #473 (ggallen) had already added a .gitignore with __pycache__/ and *.pyc — a strict superset. The review agent (run 30564767112) correctly triaged PR #570 as trivial, dispatched correctness and style-conventions sub-agents, both returned zero findings, and approved with "Looks good to me" ($1.27, ~6.5 min). Human reviewer waynesun09 caught the duplicate ~3 hours later and flagged it as HIGH priority. The PR was closed without merging in favor of #473.

Key gap

The review agent has no PR-specific check for overlapping or duplicate open PRs. Its current checks cover injection defense, metadata verification, scope authorization, and protected paths — none query GitHub for sibling PRs touching the same files. Since this was a human-created PR (not agent-created via triage), the triage agent's "Existing PR gate" was never invoked.

Existing issue coverage — no new proposals needed

This gap is well-covered by existing open issues. This retro provides additional evidence:

• agents#334: Proposes file-level overlap detection in PR-specific checks — directly covers this scenario where both PRs create the exact same file (.gitignore) with no linked issue. This retro adds a second data point (first was PR test(code): add first functional eval case for code agent #330) confirming the gap.
• fullsend#1313: Proposes blocking duplicate detection for PRs targeting the same issue — not directly applicable here (neither PR had a linked issue) but part of the same solution family.
• fullsend#1360: Proposes informational findings for PRs referencing the same linked issue — also not directly applicable but complementary.

Workflow quality assessment

• Review quality: The review agent's code-level assessment was correct — the .gitignore was well-formed. The miss was contextual (duplicate PR), not a code quality failure.
• Rework rate: N/A — PR was closed, not reworked.
• Token cost: $1.27 for a 1-line trivial change reflects framework overhead (multi-agent startup, prompt caching). Appropriate given the trivial triage path was correctly selected.
• Autonomy readiness: The human reviewer caught a real issue the agent structurally cannot detect today. Closing this gap (agents#334) would improve autonomy for the common case of overlapping housekeeping PRs.
