Review & Resolve PR Comments

Fetch every unresolved review thread on a PR, decide for each whether a code fix is needed, apply the fix (or confirm it's already done), then resolve the thread via gh GraphQL. Ask the user whenever a decision is genuinely ambiguous.

When to Use This Skill

• User says "address the PR comments" or "fix the review comments"
• User says "resolve comments on PR #N" or pastes a PR URL
• User says "check the open comments on my PR"

Steps

Execute in order. Stop and report if any step fails.

Step 1: Identify the PR

If the user provided a PR number or URL, extract the number.

Otherwise, try to detect the PR automatically from the current branch/worktree:

gh pr view --json number,url,headRefName 2>/dev/null

If that returns a PR, use it and inform the user which PR was detected (number

• title) before continuing.

If no PR is found automatically, ask:

Which PR number (or URL) should I review?

Derive OWNER, REPO, PR_NUMBER from the URL or from the current repo's git remote get-url origin. Handle both HTTPS (https://github.com/OWNER/REPO.git) and SSH (git@github.com:OWNER/REPO.git) remote formats.

Step 2: Switch gh to the repo owner account (if needed)

Extract the currently active GitHub username:

gh api user --jq '.login'

If that username does not match OWNER (derived in Step 1), switch:

gh auth switch --user <OWNER>

Note the original username so you can restore it at the end. Do NOT rely on gh auth status to determine the active user — its output format is harder to parse reliably. Use gh api user --jq '.login' instead.

Step 3: Fetch ALL unresolved review threads

Use the GitHub GraphQL API to get every thread — paginate if needed. The REST endpoint can truncate output; always use GraphQL:

gh api graphql -f query='
{
  repository(owner:"OWNER", name:"REPO") {
    pullRequest(number:PR_NUMBER) {
      reviewThreads(first:100) {
        nodes {
          id
          isResolved
          isOutdated
          comments(first:20) {
            nodes {
              databaseId
              path
              line
              body
            }
          }
        }
      }
    }
  }
}' --jq '.data.repository.pullRequest.reviewThreads.nodes[]
         | select(.isResolved == false)
         | {
             threadId: .id,
             outdated: .isOutdated,
             commentId: .comments.nodes[0].databaseId,
             path: .comments.nodes[0].path,
             line: .comments.nodes[0].line,
             body: .comments.nodes[0].body
           }'

Record the full list. If there are zero unresolved threads, report that and stop.

Step 4: Read the current file for each thread

For every unresolved thread, read the relevant file at the commented line to understand the current state of the code:

• If the thread is outdated (isOutdated: true), the code has already changed. Read the file to confirm the concern is addressed.
• If the thread is not outdated (isOutdated: false), the commented line still exists. Read it and decide:
  • Is the issue already fixed (e.g. a test was added in a new file, or the change was applied elsewhere)?
  • Does it still need a fix?
  • Is the suggestion wrong / inapplicable (stale logic, wrong assumption)?

Step 5: Triage each thread

Categorise every thread into one of three buckets:

When in doubt, pause and ask the user before placing a thread in any bucket. Never silently skip a thread.

Step 6: Apply fixes

For threads in the needs-fix bucket:

1. Make the minimal correct change to the file.
2. Build and run tests using the project's standard commands (e.g. pnpm build and pnpm vitest run for pnpm projects; npm test or yarn test for others — check package.json scripts if unsure) to confirm nothing breaks.
3. If tests fail, fix them or pause and ask the user.
4. Commit the fix:

git add <files>
git commit -m "fix: <short description of what was fixed>

Addresses PR review comment: <comment body summary>"
git push

Collect the thread IDs of all fixed threads.

Step 7: Resolve threads

For threads in not-applicable, first post a reply comment explaining why the suggestion wasn't followed, so the reviewer isn't left wondering:

gh api repos/OWNER/REPO/pulls/PR_NUMBER/comments \
  --method POST \
  -f in_reply_to=COMMENT_DATABASE_ID \
  -f body="<brief explanation: e.g. 'This is intentional — X because Y'>"

Then, for every thread in already-fixed, needs-fix (now fixed), and not-applicable, resolve via GraphQL:

gh api graphql -f query="
  mutation {
    resolveReviewThread(input: {threadId: \"THREAD_ID\"}) {
      thread { isResolved }
    }
  }
" --jq '.data.resolveReviewThread.thread.isResolved'

Verify the result is true before moving to the next thread.

Step 8: Restore original gh account

If the active account was switched in Step 2, restore it:

gh auth switch --user <ORIGINAL_ACCOUNT>

Step 9: Report

Summarise what was done:

• How many threads were found
• How many were already-fixed (just resolved)
• How many needed and received a fix
• How many were not-applicable (resolved with explanation)
• Any that were skipped pending user input (list them explicitly)

Important Notes

• Never resolve a thread without first confirming the underlying concern is addressed — either in the current code or with a new commit.
• Outdated ≠ resolved. An outdated thread may still represent a real issue in refactored code.
• Ask the user for anything that involves a design choice, trade-off, or intentional deviation from the reviewer's suggestion.
• This skill resolves threads under the repo owner's account. Always restore the original gh account at the end.
