Address Pull Request Review Comments

Fetch unresolved review comments on a GitHub PR, investigate each one, fix valid issues, reply, and resolve the threads.

Bundled Scripts

This skill includes two helper scripts in scripts/:

Script	Purpose
get-unresolved-comments.sh	Fetches only unresolved review threads via GraphQL — returns thread IDs, file paths, line numbers, and comment bodies
resolve-thread.sh	Resolves a single review thread by its node ID (PRRT_...) via the resolveReviewThread GraphQL mutation

GitHub's REST API does not expose thread resolution at all — these scripts use gh api graphql because it's the only programmatic path.

Determine the PR and Repository

Use $ARGUMENTS as the PR number if provided. Otherwise, detect it from the current branch:

gh pr view --json number,title,url,state --jq '{number, title, url, state}'

If no PR is found, ask the user for the PR number.

Get the owner and repo name if unknown (the scripts need them as separate arguments):

gh repo view --json owner,name --jq '[.owner.login, .name]'

Fetch Unresolved Comments

Use the bundled script to get only unresolved review threads:

bash <skill-path>/scripts/get-unresolved-comments.sh OWNER REPO PR_NUMBER

This returns a JSON array of unresolved threads. Each thread contains:

• id — the thread node ID (PRRT_...), needed to resolve the thread later
• path — file path the comment is on
• line — line number
• comments — array of { body, author.login, createdAt, databaseId }

Also check for top-level issue-style comments (these live in a separate API and aren't part of review threads):

gh pr view <pr-number> --comments --json comments

Skip bot-generated overview comments that list changed files without raising specific issues. Focus on comments that raise an actionable concern.

If there are no unresolved threads and no new issue-style comments, report that to the user and stop.

Triage Each Comment

For each comment that raises a specific issue or suggests a change:

1. Understand the comment

Read the comment body, the file path, and the line number. Identify what the reviewer is asking for — a code fix, a docs correction, a design concern, etc.

2. Investigate validity

Read the relevant source files to determine whether the issue is accurate:

• Valid issue: The reviewer identified a real problem (bug, inconsistency, missing case, stale docs, etc.)
• Not valid: The reviewer misread the code, or the concern doesn't apply given context they may not have seen

Important: Do not automatically assume that the commenter is correct, even if it appears that way at first glance. Think carefully and review the relevant code to determine if the comment is valid.

3. Act on it

If valid and fixable:

• Make the fix in the source code
• Run any relevant tests or inspections to verify the fix
• Stage and commit the change with a clear commit message
• Each fix gets its own commit so the reply can reference a specific SHA

If not valid or already addressed:

• Prepare a reply explaining why (with specifics — point to code, cite behavior, etc.)

If it requires a design decision or the user's judgment:

• Flag it for the user in the summary (don't fix or reply yet)

4. Reply and resolve

Reply to every actionable comment, whether you fixed it or not. Use the REST API to reply on the same review thread. Use the databaseId of the first comment in the thread's comments array (this is the root comment that started the thread):

gh api -X POST repos/<owner>/<repo>/pulls/<pr-number>/comments/<comment-database-id>/replies \
  -f body="<your reply>"

Every reply must end with an attribution line:

🤖 Generated with [Claude Code](https://claude.com/claude-code)

Keep replies concise: state what you did (or why you disagree), reference the commit SHA if you made a fix, and include the attribution.

After replying to a thread where the issue has been addressed (either fixed or explained), resolve it:

bash <skill-path>/scripts/resolve-thread.sh THREAD_ID

where THREAD_ID is the id field from get-unresolved-comments.sh output (e.g. PRRT_kwDO...).

Do not resolve threads flagged for the user's judgment — leave those open.

Push Changes

After committing all fixes, push to the PR branch. Since pushing is visible to others, confirm with the user before pushing if there's any doubt about the changes.

Summary

After processing all comments, provide a summary listing:

• How many unresolved threads were found
• Which ones were fixed and resolved (with commit SHAs)
• Which ones were replied to and resolved without code changes (and why)
• Any threads left open for the user's judgment (design decisions, ambiguous feedback, etc.)
