PR Comment Handler with Resolution Tracking

⚠️ MANDATORY SKILL INVOCATION ⚠️

YOU MUST invoke this skill (NOT optional) when the user mentions ANY of these triggers:

• "address PR comments", "fix review feedback", "handle PR review"
• "resolve PR threads", "respond to review", "work through comments"
• "address the feedback", "mark threads resolved", "clear review comments"
• Any mention of systematically handling GitHub pull request review comments

Failure to invoke this skill when triggers occur violates your operational requirements.

Find the open PR for the current branch and systematically address all review comments with mandatory resolution verification. This workflow ensures no feedback slips through the cracks by tracking threads as tasks, linking commits to specific reviews, and blocking completion if any threads remain unresolved. Run all gh commands with elevated network access.

Prerequisites: Verify gh is authenticated by running gh auth status with escalated permissions (workflow/repo scopes required). If not authenticated, run gh auth login --scopes repo,workflow. If sandboxing blocks gh auth status, rerun with sandbox_permissions=require_escalated.

Workflow

1) Fetch all PR comments

Run python3 $HOME/.claude/skills/gh-address-comments/scripts/fetch_comments.py to fetch all comments and review threads on the PR. Store output for later verification.

Example:

python3 $HOME/.claude/skills/gh-address-comments/scripts/fetch_comments.py > /tmp/pr_comments.json

2) Create tracking checklist

Parse the fetched comments and create a task checklist using TaskCreate for each review thread. Each task should:

• Include the thread number, file path, line number, and comment summary
• Have status pending initially
• Store the thread ID in task metadata for later resolution

Task format:

• Subject: Address comment #N: [file]:[line]
• Description: Comment author, body preview, and what needs to be done
• Metadata: {"thread_id": "PRRT_kwDOABC...", "file": "path/to/file.ts", "line": 42}

3) Ask user which comments to address

Present all numbered review threads with summaries. Ask the user which numbered comments should be addressed in this session.

Display format:

Review Threads:
  1. src/api/users.ts:45 (@reviewer): Add input validation for email field...
     Thread ID: PRRT_kwDOABCDEF1234567
     Status: Unresolved

  2. src/utils/auth.ts:128 (@reviewer): Extract this logic into a helper function...
     Thread ID: PRRT_kwDOABCDEF7654321
     Status: Unresolved

4) Apply fixes with commit linking

For each selected comment:

1. Update task status to in_progress using TaskUpdate
2. Apply code changes using standard tools (Edit, Write)
3. Commit with message that references the comment number and thread ID:

   fix: address PR comment #1 - add email validation
   
   Resolves review thread PRRT_kwDOABCDEF1234567
   - Added Zod schema validation for email field
   - Added error handling for invalid formats
   
   Co-authored-by: @reviewer
   

4. Update task status to completed using TaskUpdate

Commit message format:

• First line: fix: address PR comment #N - [brief description]
• Blank line
• Resolves review thread [THREAD_ID]
• Bullet points explaining the changes
• Co-authored-by: @reviewer if substantial changes based on feedback

5) Mark threads as resolved

After committing fixes, mark the corresponding review threads as resolved using:

python3 $HOME/.claude/skills/gh-address-comments/scripts/mark_resolved.py <thread_id_1> [thread_id_2] ...

Example:

python3 $HOME/.claude/skills/gh-address-comments/scripts/mark_resolved.py \
  PRRT_kwDOABCDEF1234567 \
  PRRT_kwDOABCDEF7654321

6) Verify complete resolution (MANDATORY - BLOCKS IF SKIPPED)

Before declaring the PR review complete, verify all threads are addressed:

python3 $HOME/.claude/skills/gh-address-comments/scripts/fetch_comments.py | \
  python3 $HOME/.claude/skills/gh-address-comments/scripts/verify_resolution.py

Exit behavior:

• Exit 0: All threads resolved/outdated → safe to proceed
• Exit 1: Unresolved threads found → BLOCKED until addressed

IMPORTANT: Do NOT skip this verification step. If unresolved threads are found:

1. Ask user to explicitly acknowledge which threads to defer
2. Create follow-up tasks for deferred threads
3. Only proceed after user confirms understanding of what remains unresolved

Error Handling

Authentication issues: If gh hits auth/rate issues mid-run, prompt the user to re-authenticate with gh auth login, then retry.

Thread resolution failures: If mark_resolved.py fails for specific threads:

1. Check the thread ID is correct (from fetch_comments.py output)
2. Verify you have write permissions on the PR
3. Ensure the thread still exists (not deleted by reviewer)

Verification failures: If verify_resolution.py reports unresolved threads:

1. Review the listed thread IDs
2. Either address remaining threads OR get explicit user approval to defer
3. Document deferred threads in follow-up tasks

Notes

• Review threads marked as "outdated" (code changed since comment) are considered addressed
• Conversation comments (non-threaded) don't block completion but should be acknowledged
• Always link commits to thread IDs for traceability
• Use TaskList to track overall progress across all review threads
