PR Auto-Review And Merge (Closed Loop)

This skill implements the closed-loop workflow: Review via subagent -> ICC-REVIEW receipt -> merge when NO FINDINGS -> otherwise fix and restart.

Inputs

• PR number (required): <PR-number>

Safety Rules

• Default base branch for PRs is dev. Never auto-merge a PR targeting main unless it is an explicitly requested release workflow.
• Never merge unless a merge-eligible ICC-REVIEW-RECEIPT exists for the PR's current head SHA:
  • Reviewer-Stage: 3 (temp checkout)
  • Reviewer-Agent: ... (subagent)
  • Head-SHA matches headRefOid
  • Findings: 0 and NO FINDINGS
  • Result: PASS
• GitHub approvals are OPTIONAL by default (self-review-and-merge workflow). If you want to enforce GitHub-style approvals, set workflow.require_github_approval=true.
• Merge approval:
  • If workflow.auto_merge=true (standing approval), the agent MAY merge once gates pass.
  • Otherwise, stop and wait for explicit user approval.

Workflow (Loop Until Clean)

1. Read PR metadata:
   • base branch, head SHA, head branch
   • checks status
2. Run Stage 3 review via a dedicated reviewer subagent:
   • Use Task tool to create @Reviewer and run Reviewer Stage 3 in a temp checkout.
   • Reviewer must fix findings by pushing commits to the PR branch.
   • Reviewer must re-run Stage 3 until findings are zero and checks are green.
   • Reviewer must post ICC-REVIEW-RECEIPT NO FINDINGS comment for the current head SHA.
   • Pragmatic GitHub approval (best-effort; only if workflow.require_github_approval=true): after posting NO FINDINGS receipt, reviewer subagent should:
     • Skip if an APPROVED review already exists.
     • Otherwise, attempt: gh pr review <PR-number> --approve --body "Approved based on ICC Stage 3 review receipt (NO FINDINGS)."
     • If PR author == current authenticated gh user: GitHub forbids approving your own PR (server-side rule). Skip.
       • If repo rules require approvals, merge will still be blocked; use a second GitHub identity/bot for approvals.
3. Verify merge gates (receipt + head SHA + checks green).
4. If gates fail:
   • Restart from step 2 (fresh temp checkout).
   • If repeated failures or unclear/risky changes are required, pause for a human decision.
5. If gates pass:
   • If workflow.auto_merge=true and base is dev: merge the PR (agent-performed merge; do NOT use --auto).
   • Else: stop and ask for explicit approval.

Command Snippets (Reference)

PR info:

PR=<PR-number>
gh pr view "$PR" --json number,baseRefName,headRefName,headRefOid,state,mergeable --jq .
gh pr checks "$PR"

Approval check (optional gate):

PR=<PR-number>
PR_AUTHOR=$(gh pr view "$PR" --json author --jq .author.login)
GH_USER=$(gh api user --jq .login)
APPROVALS=$(gh pr view "$PR" --json reviews --jq '[.reviews[] | select(.state=="APPROVED")] | length')
echo "Approvals: $APPROVALS"
if [ "$PR_AUTHOR" = "$GH_USER" ]; then
  echo "Self-authored PR ($GH_USER): GitHub forbids self-approval; approvals may require a bot/second identity."
fi

Receipt verification:

PR=<PR-number>
HEAD_SHA=$(gh pr view "$PR" --json headRefOid --jq .headRefOid)
RECEIPT=$(gh pr view "$PR" --json comments --jq '.comments | map(select(.body | contains("ICC-REVIEW-RECEIPT"))) | last | .body // ""')

echo "$RECEIPT" | rg -q "Reviewer-Stage: 3 \\(temp checkout\\)"
echo "$RECEIPT" | rg -q "Reviewer-Agent:.*\\(subagent\\)"
echo "$RECEIPT" | rg -q "Head-SHA: $HEAD_SHA"
echo "$RECEIPT" | rg -q "Findings: 0"
echo "$RECEIPT" | rg -q "NO FINDINGS"
echo "$RECEIPT" | rg -q "Result: PASS"

Merge (agent-performed):

gh pr merge <PR-number> --squash --delete-branch
