## How agents use BuiltWith

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

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

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