Agent Reviews

Automatically review, fix, and respond to findings from PR review bots on the current PR. Uses a deterministic two-phase workflow: first fix all existing issues, then poll once for new ones.

Path note: All scripts/agent-reviews.js references below are relative to this skill's directory (next to this SKILL.md file). Run them with node.

Phase 1: FETCH & FIX (synchronous)

Step 1: Identify Current PR

gh pr view --json number,url,headRefName

If no PR exists, notify the user and exit.

Step 2: Fetch All Bot Comments (Expanded)

Run scripts/agent-reviews.js --bots-only --unanswered --expanded

This shows only unanswered bot comments with full detail: complete comment body (no truncation), diff hunk (code context), and all replies. Each comment shows its ID in brackets (e.g., [12345678]).

If zero comments are returned, print "No unanswered bot comments found" and skip to Phase 2.

Step 3: Process Each Unanswered Comment

For each comment from the expanded output:

A. Evaluate the Finding

Read the referenced code and determine:

1. TRUE POSITIVE - A real bug that needs fixing
2. FALSE POSITIVE - Not actually a bug (intentional behavior, bot misunderstanding)
3. UNCERTAIN - Not sure; ask the user

Likely TRUE POSITIVE:

• Code obviously violates stated behavior
• Missing null checks on potentially undefined values
• Type mismatches or incorrect function signatures
• Logic errors in conditionals
• Missing error handling for documented failure cases

Likely FALSE POSITIVE:

• Bot doesn't understand the framework/library patterns
• Code is intentionally structured that way (with comments explaining why)
• Bot is flagging style preferences, not bugs
• The "bug" is actually a feature or intentional behavior
• Bot misread the code flow

When UNCERTAIN — use AskUserQuestion:

• The fix would require architectural changes
• You're genuinely unsure if the behavior is intentional
• The "bug" relates to business logic you don't fully understand
• Multiple valid interpretations exist
• The fix could have unintended side effects

B. Act on Evaluation

If TRUE POSITIVE: Fix the code. Track the comment ID and a brief description of the fix.

If FALSE POSITIVE: Do NOT change the code. Track the comment ID and the reason it's not a real bug.

If UNCERTAIN: Use AskUserQuestion. If the user says skip, track it as skipped.

Do NOT reply to comments yet. Replies happen after the commit (Step 5).

Step 4: Commit and Push

After evaluating and fixing ALL unanswered comments:

1. Run your project's lint and type-check
2. Stage, commit, and push:

   git add -A
   git commit -m "fix: address PR review bot findings
   
   {List of bugs fixed, grouped by bot}"
   git push
   

3. Capture the commit hash from the output.

Step 5: Reply to All Comments

Now that the commit hash exists, reply to every processed comment:

For each TRUE POSITIVE:

Run scripts/agent-reviews.js --reply <comment_id> "Fixed in {hash}. {Brief description of the fix}"

For each FALSE POSITIVE:

Run scripts/agent-reviews.js --reply <comment_id> "Won't fix: {reason}. {Explanation of why this is intentional or not applicable}"

For each SKIPPED:

Run scripts/agent-reviews.js --reply <comment_id> "Skipped per user request"

DO NOT start Phase 2 until all replies are posted.

Phase 2: POLL FOR NEW COMMENTS (loop until quiet)

The watcher exits immediately when new comments are found (after a 5s grace period to catch batch posts). This means you run it in a loop: start watcher, process any comments it returns, restart watcher, repeat until the watcher times out with no new comments.

Step 6: Start Watcher Loop

Repeat the following until the watcher exits with no new comments:

6a. Launch the watcher in the background:

Run scripts/agent-reviews.js --watch --bots-only as a background task.

6b. Use TaskOutput to wait for the watcher to complete (blocks up to 12 minutes).

6c. Check the output:

• If new comments were found (output contains EXITING WITH NEW COMMENTS):

  1. Use --detail <id> to read each new comment's full detail
  2. Process them exactly as in Phase 1, Steps 3-5 (evaluate, fix, commit, push, reply)
  3. Go back to Step 6a to restart the watcher

• If no new comments (output contains WATCH COMPLETE): Stop looping and move to the Summary Report.

Summary Report

After both phases complete, provide a summary:

## PR Review Bot Resolution Summary

### Results
- Fixed: X bugs
- Already fixed: X bugs
- Won't fix (false positives): X
- Skipped per user: X

### By Bot
#### cursor[bot]
- BUG-001: {description} - Fixed in {commit}
- BUG-002: {description} - Won't fix: {reason}

#### Copilot
- {description} - Fixed in {commit}

### Status
✅ All findings addressed. Watch completed.

Important Notes

Response Policy

• Every finding gets a response - No silent ignores
• Responses help train bots and document decisions
• "Won't fix" responses prevent the same false positive from being re-raised

User Interaction

• Use AskUserQuestion when uncertain about a finding
• Don't guess on architectural or business logic questions
• It's better to ask than to make a wrong fix or wrong dismissal

Best Practices

• Verify findings before fixing - bots have false positives
• Keep fixes minimal and focused - don't refactor unrelated code
• Ensure type-check and lint pass before committing
• Group related fixes into a single commit
• Copilot suggestion blocks often contain ready-to-use fixes
