## How agents use Nusii proposals

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

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

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