          ```json
          {trigger_json}
          ```

          Use these rollout rules:
          1. If task_set is `changelog`, run only the changelog task. If `all`, run all default tasks.
          2. Use `warpdotdev/channel-versions` at {channel_versions_ref} as the source of `channel_versions.json`.
          3. Create and switch to a release docs feature branch before invoking `run_release_updates.py --create-pr`; the script refuses to create a PR from `main`.
          4. Create or update a PR against `warpdotdev/docs` `main` only if generated changes exist.
          5. Use a draft PR when create_draft_pr is true. Note: --pr-draft and --pr-auto-merge are mutually exclusive; never pass both.
          6. Run `npm run build` before considering the PR ready for review.
          7. If no docs changes are needed, report a no-op result and do not open a PR.
          8. After creating the PR: post a Slack notification to the #oncall-client Slack channel (ID: C06MT1NRBFV).
             - Resolve the oncall-client-primary and oncall-client-secondary Slack user groups via the Slack usergroups.list API (DOCS_SLACK_BOT_TOKEN).
             - Message format: ":books: New release docs PR ready for review\n<PR_URL>\n<!subteam^PRIMARY_ID|oncall-client-primary> <!subteam^SECONDARY_ID|oncall-client-secondary> please take a look when you get a chance."
             - If DOCS_SLACK_BOT_TOKEN is unset, skip silently and log a warning.
