PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This PR ships the missing harness-entry layer with the smallest substrate surface: one read-on-demand workflow plus the already-updated epic pointer. Requesting a startup-doc update here would collapse the sibling #13043 overhaul back into this leaf and increase coupling without improving the merged workflow artifact.

Peer-Review Opening: I reviewed this as the cross-family peer pass for the harness workflow leaf. The implementation is correctly narrow and avoids turning the workflow into a second copy of ADR 0020 or the epic plan-of-record.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Issue #13042, Epic #13012 body and plan-of-record, ADR 0020 from origin/dev, changed-file list for PR #13044, open-PR collision state, Project 13 reference from the ticket/ADR, and the pr-review / turn-memory-pre-flight review payloads.
• Expected Solution Shape: A correct patch should create exactly one short read-on-demand workflow entry, point to ADR 0020 + board 13 + M1-M4 + lane/venue/quota disciplines, and avoid duplicating the ADR, epic body, or skill payloads. It should not hardcode live board state or expand into AGENTS_STARTUP.md, because #13043 owns that larger startup-substrate overhaul. Test isolation is static/docs-only: line count, link/path resolution in the merged target, close-target audit, and CI/body lint are sufficient.
• Patch Verdict: Matches the expected shape. The diff adds only .agents/workflows/agent-harness.md at 17 lines, the epic body now contains the workflow pointer, and GitHub reports the PR clean against dev with all checks green.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #13042
• Related Graph Nodes: Refs #13012, ADR 0020, #13043, .agents/workflows/agent-harness.md

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: The only edge case is branch-local link behavior: the raw PR head branch predates the ADR 0020 commit, so the relative ADR link does not resolve if a reviewer reads the branch in isolation. I verified origin/dev already contains learn/agentos/decisions/0020-agent-harness-concept.md and GitHub reports mergeStateStatus: CLEAN, so the merged artifact resolves; this is not a Required Action, but it is worth remembering for cold-entry tests that consume PR branches rather than merged dev.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches the diff; it ships a procedural entry workflow, not a full harness plan.
• Anchor & Echo summaries: N/A, no code/JSDoc surface.
• [RETROSPECTIVE] tag: N/A, no tag used.
• Linked anchors: #13042, #13012, ADR 0020, and #13043 support the stated boundaries.

Findings: Pass with the branch-local-link caveat above; no blocking rhetorical drift.

🧠 Graph Ingestion Notes

• [KB_GAP]: None. KB and ADR 0020 both identify the same session-intake shape: ADR first, board 13 second, target work item third.
• [TOOLING_GAP]: Memory Core raw self-review detection degraded with chroma-error-finding-id; this was not treated as a genuine no-match. Peer-review mode is still independently established by PR author / ticket authority, not by the failed query.
• [RETROSPECTIVE]: The workflow-vs-skill split is the right Progressive Disclosure placement: mission entry sequence in .agents/workflows/, task-class discipline remains in .agents/skills/, and live state stays on Project 13 / issue bodies.

🎯 Close-Target Audit

• Close-targets identified: #13042
• #13042 is not epic-labeled; labels are documentation, enhancement, ai.

Findings: Pass.

📑 Contract Completeness Audit

Findings: N/A. This is a documentation/workflow-entry convention, not a runtime/API/config/MCP contract surface. The ticket body itself is the acceptance contract, and the cross-skill integration audit below covers downstream documentation effects.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line: L1 docs-only.
• Achieved evidence matches the static portion of the close-target ACs: file exists, is short, points at ADR 0020/board/milestones/discipline anchors, and keeps live details by reference.
• Residual cold-entry AC is explicitly listed in Post-Merge Validation.
• Evidence language does not promote L1 docs proof into L3/L4 runtime proof.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A. No OpenAPI or MCP tool-description surface touched.

🔗 Cross-Skill Integration Audit

• Existing skill predecessor check: no existing skill needs to trigger .agents/workflows/; this is intentionally read-on-demand mission entry, not trigger-loaded task discipline.
• AGENTS_STARTUP.md check: startup integration is a real adjacent need, but it is already isolated in sibling #13043, whose scope includes the stale workflow-skill references and startup-doc pruning. Keeping it out of this PR preserves #13042's narrow leaf shape.
• Reference-file check: the workflow points at skills by name and avoids duplicating their payloads.
• Convention documentation check: the convention is documented at the file head in the first workflow, satisfying the ticket's file-head vs sibling-README choice.

Findings: All checks pass — no integration gap for this leaf. #13043 remains the correct follow-up owner for broader startup discoverability.

🧪 Test-Execution & Location Audit

• Branch checked out locally via checkout_pull_request.
• Canonical Location: .agents/workflows/agent-harness.md is the new convention location prescribed by #13042.
• No test file changed.
• No code changed; docs-only verification was line count, diff check, close-target labels, merge-target ADR presence, and CI check state.

Findings: No tests needed for docs-only change. git diff --check origin/dev...HEAD passed; CI is green.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 96 - 4 points deducted only for the branch-local ADR link caveat; merged-target alignment is correct and the workflow does not duplicate ADR/skill/epic payloads.
• [CONTENT_COMPLETENESS]: 96 - 4 points deducted for leaving the cold-entry AC as post-merge validation rather than already proven; the static ticket ACs are otherwise covered in 17 lines.
• [EXECUTION_QUALITY]: 94 - 6 points deducted for the raw-head link nuance and the unavoidable docs-only evidence ceiling; static checks, line count, close-target audit, and CI are clean.
• [PRODUCTIVITY]: 100 - I actively considered missing workflow file, missing convention statement, missing epic pointer, over-duplication of ADR/skills, and absent cold-entry residual; none apply after the current evidence checks.
• [IMPACT]: 55 - Moderate: this establishes a new read-on-demand coordination convention and unblocks cold harness entry, but it is deliberately not a runtime subsystem or always-loaded rule change.
• [COMPLEXITY]: 24 - Low: one new markdown file and one already-applied epic-body pointer, with complexity mostly in cross-skill boundary discipline rather than implementation mechanics.
• [EFFORT_PROFILE]: Quick Win - High coordination value for very small diff size; the PR reduces re-derivation cost without increasing always-loaded context.

Cross-family approval posted. Human merge gate remains human-only.
