Quick start

Two entry paths: work with the agent in the Agents tab, or call a saved Format over the API. Most teams do both — author in Agents, then invoke the recipe from their backend.

New to the product map? Read Sume basics first — Agents, Formats, Models, and which surface is primary for partners.

Option 1: Start it from one brief

Paste this into the composer at sume.com/agents. The thread keeps every artifact and approval.

Option 2: Work the thread

Use the Agents tab when a person should stay in the loop: brief, review, iterate, then save the result as a reusable recipe.

  1. Open the Agents tab

    Sign in and start a thread. Nothing to install.

  2. Brief the agent

    Describe the deliverable, not the tool calls. The agent picks the models, and asks before it spends.

  3. Save the recipe as a Format

    A Format is the same thread's recipe, addressable by handle and slug — that is what your backend calls later.

Next: Agents overview.
