 The main agent should **not wait** for the reply agent — continue to Step 7 immediately.
 
 **Important:** Do NOT use `--resolve-thread` unless the user explicitly asks to resolve threads. Only reply.
 
 **When the user asks to resolve threads**, add `--resolve-thread` to the reply commands:
 ```bash
-tools github review <pr> --respond "Fixed in abc1234" --resolve-thread -t <thread-id1>,<thread-id2>
+tools github review <pr> --respond "@coderabbitai Fixed in abc1234" --resolve-thread -t <thread-id1>,<thread-id2>
 ```
 
 **Permission note:** `--resolve-thread` uses `resolveReviewThread` GraphQL mutation. Fine-grained PATs may fail with "Resource not accessible by personal access token" even with `pull_requests:write` set, because GitHub does not support this mutation for fine-grained PATs. The tool now automatically falls back to the `gh` CLI token (classic OAuth with `repo` scope) which always has the needed permission. No manual action required.
