Anatomy
- Name & description — what this Agent is for.
- Model — Sonnet / Opus / Haiku.
- System prompt — the instructions this Agent always operates under.
- Skills — capability packs (see Skills).
- Allowed tools — subset of the global tool registry this Agent can use.
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.
