Anatomy
- Name & description — what this Agent is for.
- Model — Sonnet / Opus / Haiku.
- System prompt — the instructions this Agent always operates under.

When to use an Agent vs an inline node
- Agent — reusable across many Flows, or has a scoped set of tools you don’t want in the general pool.
- Inline action / agent node — one-off, specific to this Flow.
