pr-review-loop（公关审查循环）

PR Review Loop

Autonomous cycle: Greptile reviews PR → agent fixes feedback → pushes → re-triggers → repeats until score ≥ 4/5 or max rounds.

Quick Start

When triggered with a PR URL or review payload:

# Run the review loop
bash scripts/pr-review-loop.sh <owner/repo> <pr-number>

Or invoke steps manually — see below.

Workflow

1. Fetch Review

# Get latest Greptile review
gh api "/repos/{owner}/{repo}/pulls/{pr}/reviews" \
  --jq '[.[] | select(.user.login == "greptile-apps[bot]")] | last'

# Get inline comments
gh api "/repos/{owner}/{repo}/pulls/{pr}/comments" \
  --jq '[.[] | select(.user.login == "greptile-apps[bot]")]'

2. Parse Score

Look for confidence/quality score in review body. Greptile typically includes a score like Score: X/5 or Confidence: X/5. Extract it:

• Score ≥ 4/5 → auto-merge
• Score < 4/5 → fix issues
• No score found → treat as needing fixes if there are comments, otherwise merge

3. Auto-Merge (score ≥ 4)

gh pr merge <number> --merge --delete-branch --repo <owner/repo>

4. Fix Issues (score < 4)

For each Greptile comment:

1. Read the file and line referenced
2. Understand the feedback
3. Apply the fix
4. Stage changes

Commit with a descriptive message listing each fix:

Address Greptile review feedback (round N)

- Fix X in path/to/file.ts
- Fix Y in path/to/other.ts
- Improve Z per reviewer suggestion

Push and re-trigger:

git push
gh pr comment <number> --repo <owner/repo> --body "@greptileai review"

5. Track State

Maintain review-state.json in workspace:

{
  "owner/repo#123": {
    "rounds": 2,
    "maxRounds": 5,
    "lastScore": 3,
    "sameScoreCount": 1
  }
}

Update after each round. Check exit conditions:

• rounds ≥ 5 → merge anyway, notify Master
• sameScoreCount ≥ 2 (same score 2 rounds in a row) → merge anyway, notify Master

6. Escalation

• Architectural decisions (review mentions architecture, design patterns, breaking changes) → ping Master on Telegram, don't auto-fix
• Max rounds reached → merge + notify Master with summary
• Unclear feedback → ask Master

Command Interface

Agents should respond to:

• pr review <url> — start review loop on a PR
• pr review <owner/repo#number> — same, by reference
• pr status — show active review loops and their state
