Then open index.ts. The agent is defined with defineAgent({ steps }); each step is a defineStep({ name, next, run }). The run body is ordinary code — and inside it, the full Sapiom tool catalog is available, pre-auth'd and tenant-scoped, on ctx.sapiom:
const box = await ctx.sapiom.sandboxes.create({ name: "demo" });
const repo = await ctx.sapiom.repositories.create("my-repo");
No credentials to wire — a per-execution tenant credential is injected for each agent run.
Author and run this agent with the Sapiom dev tools:
ctx.sapiom.* calls resolved from stubs, iterating until completion without Sapiom capability spend. Ordinary code in the project can still make its own network or machine changes.npm run typecheck and npm run format are also available for editor-level checks.
See AGENTS.md for the full authoring loop.
