pr-wrangler-review-bot-comments

Automatically resolve findings from PR review bots (Copilot, Cursor Bugbot, CodeRabbit, etc.) on the current PR. Uses a two-phase workflow: fix all existing issues, then poll for new ones until bots go quiet.

Prerequisites

All commands below use npx pr-wrangler-reviews. If the project uses a different package manager, substitute the appropriate runner (e.g., pnpm dlx pr-wrangler-reviews for pnpm, yarn dlx pr-wrangler-reviews for Yarn, bunx pr-wrangler-reviews for Bun). Honor the user's package manager preference throughout.

Cloud environments only (e.g., Codespaces, remote agents): verify git author identity so CI checks can map commits to the user. Run git config --global --get user.email and if empty or a placeholder, set it manually. Skip this check in local environments.

Phase 1: FETCH & FIX (synchronous)

Step 1: Fetch All Bot Comments (Expanded)

Run npx pr-wrangler-reviews --bots-only --unanswered --expanded

The CLI auto-detects the current branch, finds the associated PR, and authenticates via environment variables (GITHUB_TOKEN/GH_TOKEN), stored OAuth tokens, or gh CLI as fallback. If anything fails (no token, no PR, CLI not installed), it exits with a clear error message.

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 2: 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 -- ask the user:

• 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: Ask the user. If they say skip, track it as skipped.

Do NOT reply to comments yet. Replies happen after the commit (Step 4).

Step 3: 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 4: Reply to All Comments

Now that the commit hash exists, reply to every processed comment. The --resolve flag marks the review thread as resolved on GitHub.

For each TRUE POSITIVE:

Run npx pr-wrangler-reviews --reply <comment_id> "Fixed in {hash}. {Brief description of the fix}" --resolve

For each FALSE POSITIVE:

Run npx pr-wrangler-reviews --reply <comment_id> "Won't fix: {reason}. {Explanation of why this is intentional or not applicable}" --resolve

For each SKIPPED:

Run npx pr-wrangler-reviews --reply <comment_id> "Skipped per user request" --resolve

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 5: Start Watcher Loop

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

5a. Launch the watcher in the background:

Run npx pr-wrangler-reviews --watch --bots-only as a background task.

5b. Wait for the background command to complete (default 10 minutes; override with --timeout).

5c. 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 2-4 (evaluate, fix, commit, push, reply)
  3. Go back to Step 5a 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

• Ask the user 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
