Reply to PR Threads

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

Step 1: Run /github-voice Skill

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

Step 2: 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 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 or hedge.

answer: payload is raw answer text from /answer-reviewer-questions. Tighten to one or two sentences and apply /github-voice rules (no em dashes, natural tone). Do not cite transcripts or mention Claude.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 [email protected]/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.
