description	Draft, confirm, and post replies to GitHub PR review threads. Handles per-category reply formatting, re-fetches thread resolution state so auto-resolved threads are skipped, and posts via GraphQL. Use when the user asks to "reply to PR threads", "post PR thread replies", or "draft PR reply messages".

Reply to PR Threads

Draft replies for a processed review-thread list, confirm with the user, and post the surviving drafts.

Step 1: Re-fetch Thread State

Auto-detect owner, repo, and PR number from the current branch if not provided, then query the current resolution state:

gh api graphql -f query='
query($owner: String!, $repo: String!, $pr: Int!) {
  repository(owner: $owner, name: $repo) {
    pullRequest(number: $pr) {
      reviewThreads(first: 100) {
        nodes { id isResolved }
      }
    }
  }
}' -f owner='{owner}' -f repo='{repo}' -F pr={pr_number}

Drop threads whose isResolved is now true. Reviewers or bots such as CodeRabbit may resolve threads after the original fetch, and drafting replies for them is wasted work.

Step 2: Run /github-voice Skill

Run the /github-voice skill to load voice rules and the insider-vs-outsider detection.

Step 3: Draft Replies

Use the processed-thread list from conversation context. Each entry has: thread id, file path, line, category (fix, skip, answer, or clarify), and per-category payload.

Keep every reply to one or two sentences. No bullet-point reasoning. No bolded labels.

fix: payload is a commit SHA, optionally with a divergence note.

Fixed in <commit-sha>.

Only add a brief sentence after the SHA when the fix meaningfully diverges from what the reviewer suggested. Otherwise the SHA alone is enough.

skip: payload is the skip reasoning. State the reasoning directly. Do not apologize.

answer: payload is raw answer text from /answer-reviewer-questions. Tighten to one or two sentences and apply /github-voice rules. Do not cite transcripts or mention Claude. The reply reads as the implementer's own explanation.

clarify: payload is a user-directed question. Draft it as directed.

Step 4: Present Drafts and Confirm

Output all drafts as text, grouped by file:

### <file-path>

**Thread <id>** (<category>, line <line>)
Reviewer: <original comment, truncated if long>
Reply: <drafted reply>

Then use AskUserQuestion to ask whether to post. Offer:

• Post — post all drafts as shown
• Cancel — skip posting

Step 5: Post Replies

For each approved draft, write the drafted reply to .turbo/pr/thread-<thread-id>.md with the Write tool, then post via the reply mutation:

gh api graphql -f query='
mutation($threadId: ID!, $body: String!) {
  addPullRequestReviewThreadReply(input: {pullRequestReviewThreadId: $threadId, body: $body}) {
    comment { id }
  }
}' -f threadId='<thread-id>' -F body=@.turbo/pr/thread-<thread-id>.md

Substitute <thread-id> with the thread's id for each post. Report what was posted and what was skipped (due to auto-resolution between re-fetch and posting).

Then use the TaskList tool and proceed to any remaining task.

Rules

• Never resolve or dismiss a review thread. Only reply. Let the reviewer resolve.
• If a post mutation fails because the thread is already resolved, log the skip and continue with the rest.
