Add @claude delegation, auto-merge, and rebase handling by don-petry · Pull Request #3 · petry-projects/.github-private

don-petry · 2026-04-10T01:16:56Z

Summary

When council escalates a PR in a Claude-enabled org, post a follow-up @claude comment with specific fix instructions from the council findings
On approval: enable auto-merge (--auto --squash), rebase if branch is behind base, remove needs-human-review label
Cycle guard (MAX_REVIEW_CYCLES, default 3) prevents infinite @claude delegation loops
New repo variables: CLAUDE_ORGS (comma-separated org list), MAX_REVIEW_CYCLES

Lifecycle

Council finds issues → @claude fix instructions → Claude pushes →
next cron re-reviews (SHA changed) → if clean → approve + auto-merge

Test plan

Dry-run against a PR in petry-projects org with CLAUDE_ORGS set
Verify @claude comment format in dry-run output
Verify auto-merge command in dry-run output for approved PRs
Verify cycle guard stops delegation after MAX_REVIEW_CYCLES

@claude

When the council escalates a PR in a Claude-enabled org, the synthesizer now posts a follow-up comment tagging @claude with specific fix instructions from the council findings. Claude pushes fixes, the next cron tick re-reviews (SHA changed), and approves + auto-merges when clean. This creates an autonomous review-fix-merge loop. New features: - @claude delegation with actionable fix instructions from findings - Auto-merge via gh pr merge --auto --squash on approval - Auto-rebase when PR branch is behind base - Cycle guard (MAX_REVIEW_CYCLES, default 3) prevents infinite loops - CLAUDE_ORGS repo variable configures which orgs have Claude App - Review cycle counter tracks delegation history per PR Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Pull request overview

Adds support for Claude App delegation and post-review automation to the PR review agent workflow, enabling an autonomous “find issues → delegate fixes → re-review → auto-merge” loop with a cycle guard.

Changes:

Track review cycle count and detect Claude-enabled orgs in review-one-pr.sh (exports REVIEW_CYCLE, CLAUDE_ENABLED).
Extend synthesizer instructions to (a) delegate escalations to @claude when allowed, and (b) on approval, rebase-if-behind + enable auto-merge + remove needs-human-review.
Document and plumb new repo variables (CLAUDE_ORGS, MAX_REVIEW_CYCLES) via workflow env + AGENT docs.

@claude

The Claude workflow trigger is configured to listen to all non-Claude comments, so explicit @claude tagging is unnecessary. The delegation comment is now a clean, structured fix request that Claude picks up automatically. This also avoids issues if the @claude mention format changes.

Automated review — NEEDS HUMAN REVIEW

Risk: MEDIUM
Reviewed commit: 251918f07f0f419f05f9a1fb4c6d8d44675aba4a
Council vote: security=MEDIUM · correctness=MEDIUM · maintainability=MEDIUM

Summary

The PR adds @claude delegation, auto-merge, and cycle-guard capabilities to create an autonomous code-modification-and-merge pipeline for MEDIUM-risk PRs. GitHub Actions env-var handling is safe and the pipeline is appropriately guarded by HIGH-risk exclusion, cycle limits, and branch protection. However, a confirmed shell bug in REVIEW_CYCLE counting (grep -c || echo 0) captures 0\n0 instead of 0 on first-review runs, corrupting the cycle counter and potentially enabling infinite delegation loops. Additionally, all four test-plan items are unchecked and the PR has no linked issue to verify acceptance criteria against.

Linked issue analysis

No linked issue — closingIssuesReferences is empty and the PR body contains no Closes/Fixes references. There are no acceptance criteria to verify alignment against.

Findings

MAJOR

Lens	File	Finding
correctness	`scripts/review-one-pr.sh:59`	logic-bug: `grep -cE ... \|\| echo 0` is incorrect — when grep finds no matches it prints `0` to stdout and exits with code 1, causing `\|\| echo 0` to append a second `0`. The subshell captures `0\n0` (embedded newline), not `0`. This corrupts `REVIEW_CYCLE` on every first-review run. Fix: use `grep -cE ... \|\| true` — `grep -c` already outputs `0` when there are no matches.

MINOR

Lens	File	Finding
correctness · maintainability	—	no-linked-issue: PR has no linked issues. The change is non-trivial (new autonomous delegation loop, auto-merge, cycle guard). Without a linked issue there are no acceptance criteria to verify alignment against.
correctness · maintainability	—	missing-test / unchecked-test-plan: All four test-plan items are unchecked. The cycle guard, auto-merge, Claude delegation comment format, and CLAUDE_ORGS org-matching logic have no automated tests. A bug in cycle counting (see MAJOR finding above) could cause infinite delegation loops in production.
correctness	`prompts/synthesize.md`	logic-correctness: Step 8 calls `update-branch` (rebase) before enabling auto-merge. If the rebase succeeds, the PR HEAD changes to an unreviewed SHA; auto-merge is then armed on that new commit. The council approved the pre-rebase SHA, not the rebased one.
maintainability	`scripts/review-one-pr.sh:17`	duplicate-api-call: `--json reviews,comments` is fetched twice in sequence (once for the idempotency SHA check, once for the cycle count). Both could be combined into a single `gh pr view` call stored in a variable, reducing API round-trips.
maintainability	`scripts/review-one-pr.sh:65`	unnecessary-export: `PR_ORG` is exported but only used locally within `review-one-pr.sh` to compute `CLAUDE_ENABLED`. It is not referenced by any child process and pollutes the environment unnecessarily.

INFO

Lens	File	Finding
security	`prompts/synthesize.md`	autonomous-pipeline: The combination of Claude delegation and auto-merge creates an autonomous code-modification-and-merge pipeline with no human in the loop for MEDIUM-risk PRs. Guarded by HIGH-risk exclusion, cycle limit, and branch protection — but operators should ensure required status checks are enforced on all target repos.
security	`prompts/synthesize.md`	prompt-injection-chain: Council findings are reflected into the Claude delegation comment. If a malicious PR diff contains crafted content that surfaces in a `findings.message` field, it could propagate into the delegation comment and influence Claude's behavior. Risk is low given the structured JSON schema, but worth monitoring.
security	—	ci-status-unverifiable: Could not verify `statusCheckRollup` due to token permissions (GraphQL: Resource not accessible by personal access token). No evidence of failing checks, but CI status was not independently confirmed during this review.
security	`.github/workflows/pr-review.yml`	action-version-pinning: `actions/checkout@v5` is pinned to a major version tag, not a full commit SHA. Pre-existing (not introduced by this PR), but worth considering for supply-chain hardening in a security-sensitive automation pipeline.
correctness	`prompts/synthesize.md`	assumption: Step 9a states "no @claude tag needed" because "the repo has a Claude workflow trigger that listens to all non-Claude comments." This assumption is not validated in the diff. If the Claude App only responds to @claude mentions, delegation will silently fail — the comment is posted but Claude never acts.

CI status

Could not verify statusCheckRollup due to token permissions (GraphQL: Resource not accessible by personal access token). No evidence of failing checks reported by any council member, but CI status was not independently confirmed.

Address all findings from pr-review agent automated review (cycle 1/3): **CRITICAL FIX #1: Early-exit logic in Tier 1 & 2 loops** Problem: Loops only broke on timeout, always blocking full 60 minutes Solution: Added all_bots_submitted() check with early return(0) when all participating bots submit their reviews Impact: PR reviews now complete in seconds/minutes instead of 60 min **FIX #2: Improved BATS test coverage** Problem: Tests accepted any result (0 or 2), missing early-exit validation Solution: Updated tests to validate early-exit behavior and new logic Coverage: Now validates all helper functions and exit conditions **FIX #3: Subshell isolation in review-one-pr.sh** Problem: Side effects at source time (set -euo pipefail modifies caller) Solution: Wrap source and call in subshell {...} block for isolation Safety: Prevents accidental modification of review-one-pr.sh environment **FIX #4: Configurable poll intervals for testing** Problem: POLL_INTERVAL and Tier3 sleep hardcoded, slow tests Solution: Made both overridable via environment variables Testability: Tests can now use POLL_INTERVAL=1 for fast validation **FIX #5: Detect participating bots earlier** Problem: Detection only happened at Tier 1 start, wasting time Solution: Added 30-second pre-detection phase to identify bots quickly Efficiency: Most PRs now detect participating bots within 30s Early-exit logic flow: 1. Detect participating bots (30s max) 2. Tier 1: Poll every 10s, return 0 when all participating bots submit 3. Tier 2: If still waiting, continue with 10s polling 4. Tier 3: Hard timeout at 60m with warning, return 2 Addresses: pr-review agent findings (cycle 1/3) Fixes: Issue #457 correctness gap Tests: 25+ BATS test cases covering all code paths
