## How agents use Dictionary Api

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

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

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