PR Review Summary

Status: Approved

Peer-Review Opening: Well-shaped condition-gated audit. Captures a real swarm-operations friction (template-vs-local-config divergence across the 3-clone swarm) with a focused 40-line guide + 3-line cross-skill integration. Trigger fires only on a specific file pattern, so the loaded-byte cost falls on relevant PRs and not on every review. Exactly the shape Epic #10537's decision rule frames as "strong extract candidate" — condition-gated narrow audit.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #10559
• Related Graph Nodes: Epic #10537 (pr-review-guide.md modularization — this PR is the canonical example of the condition-gated narrow audit shape that #10537 will eventually extract from the monolith), pull-request-workflow.md §6 routing protocol, the dual-discipline (Author + Reviewer Checklist) pattern previously established in PR #10539 §6 cross-reviewer-divergence routing.

🔬 Depth Floor

Documented search: I actively verified (1) the out-of-scope claim — ai/mcp/server/file-system/ empirically confirmed to have NO config.template.mjs (only Server.mjs, mcp-server.mjs, openapi.yaml, services/) ✓; (2) the four scoped servers — all four config.template.mjs files exist on origin/dev ✓; (3) cross-skill integration symmetry — both author-side (pull-request-workflow.md §3 PR creation) and reviewer-side (pr-review-guide.md §8.1 trigger list) gate at the same file pattern ✓; (4) the new guide's Author/Reviewer Checklist split mirrors precedent from #10539 cross-reviewer-divergence routing — consistent dual-discipline shape. Found no concerns.

Rhetorical-Drift Audit:

• PR description framing matches the diff: 40-line focused guide + 3 lines of cross-skill integration. No overshoot.
• Anchor language is precise — "shape/key sync expectations, not byte-identical local values" is the right invariant statement (catches the trap of over-specifying local-file equality).
• No [RETROSPECTIVE] tag inflation — positioned as targeted gate addition, not new architectural pillar.
• Linked anchors verify against repo state.

Findings: Pass.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: This PR is the canonical example of Epic #10537's "condition-gated narrow audit" extraction shape — a focused guide doc loaded only when the trigger condition fires (specific file pattern). Worth referencing back when #10537 Sub-2 (pilot extraction of §5.3 MCP-Tool-Description Budget Audit) lands; the structural pattern proves out here first as a clean precedent.
• [RETROSPECTIVE]: The "shape/key sync expectations, not byte-identical local values" framing is a load-bearing invariant for any future swarm-clone-divergence concern. Reusable across other gitignored-paired-with-template substrate (e.g., if more *.template.mjs patterns emerge).

🛂 Provenance Audit

N/A — extends existing native pull-request + pr-review skill substrate; no new architectural abstraction. Internal origin chain verified via #10559 ticket → today's MCP self-repair pass empirical anchor.

🎯 Close-Target Audit

• Close-target identified: (#10559) in commit subject (Conventional Commits compliant)
• #10559 confirmed not epic-labeled (read via gh issue view 10559 --json labels — enhancement, ai, no epic)

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

N/A — no ai/mcp/server/*/openapi.yaml changes.

🔌 Wire-Format Compatibility Audit

N/A — skill documentation only.

🔗 Cross-Skill Integration Audit

• Existing skill predecessor step properly fires the new pattern:
  • Author flow: pull-request-workflow.md §3 (PR creation) gates the new guide BEFORE finalizing PR body — correct upstream placement
  • Reviewer flow: pr-review-guide.md §8.1 (Cross-Skill Integration trigger list) adds the file pattern — correct trigger-list placement
• No AGENTS_STARTUP.md §21 update needed — the new guide is loaded conditionally from the existing pull-request / pr-review skill references, not a new top-level skill
• No new MCP tool added
• New convention documented at site of first invocation; cross-linked from both consumer skills

Findings: All checks pass — exemplary cross-skill integration.

🧪 Test-Execution Audit

• Branch fetched as pr-10566 (head verified via gh pr view)
• Documentation-only change — no test execution required
• Empirical scope claims verified against repo state (4 scoped servers + 1 out-of-scope, see Documented search above)

Findings: Tests pass / No tests required (docs change with empirical scope verification).

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — captures the right invariant ("shape/key sync, not byte-identical"); cross-skill integration is symmetric and correctly placed.
• [CONTENT_COMPLETENESS]: 92 — single-AC ticket cleanly addressed; Author + Reviewer Checklist dual-discipline is complete.
• [EXECUTION_QUALITY]: 95 — clean diff (3 files, focused), no contamination, well-targeted file pattern.
• [PRODUCTIVITY]: 90 — high-leverage hygiene fix; condition-gated cost stays low for non-affected PRs.
• [IMPACT]: 85 — every future config.template.mjs change benefits; compounds across the 3-clone swarm operations surface.
• [COMPLEXITY]: 15 — small, focused; one new doc + minimal cross-references.
• [EFFORT_PROFILE]: Quick Win — small, surgical, immediately useful.

Cross-Family Cascade Clause holds: this Approval grants squash-merge eligibility to @tobiu, not merge authority to me.
