# Engine Session-Scoped Tools
These tools are **not** part of the pi extension's user-invokable `extension.ts` surface. They are injected by the engine at runtime for specific agent session types.
- Source files: `packages/engine/src/agent-tools.ts`, `triage.ts`, `executor.ts`, `merger.ts`, `agent-heartbeat.ts`
- Availability: only when the engine creates a session for the matching agent role
- Important: do not tell users to call these directly from the generic pi extension tool list
