## How agents use HackerRank Work

Inside a Definable workflow, HackerRank Work is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → HackerRank Work** — the Researcher (GPT-5.5) pulls context from HackerRank Work (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → HackerRank Work** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into HackerRank Work (create record, post message, draft email).
- **Designer / Engineer → Distributor → HackerRank Work** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via HackerRank Work (attach file, open PR comment, post status).

The Verifier checks every HackerRank Work call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
