## Tools available

**1** tools available. First 1:

- `ECHTPOST_LIST_TEMPLATES` — List templates — This tool retrieves a list of all available templates in the Echtpost account. Templates serve as the base design for postcards and are essential for creating cards. The action operates independently using only an authentication token and returns detailed template information including id, name, description, preview URL, type, and creation time. This action is crucial for viewing templates before creating cards and obtaining the necessary template IDs for subsequent actions.

## Auth

Auth schemes: `API_KEY`.

## How agents use Echtpost

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

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

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