## How agents use Synthflow AI

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

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

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