Brain 05 of 25 · Agent Tooling
Tool Use Brain.
Selects, invokes, and audits external tool calls within signed permissioned scopes.
What this brain does
The Tool Use Brain decides which Mickai-permissioned tool to invoke for a given step, drives the invocation, parses the response, and signs the entire round-trip into the audit ledger. Every tool call is gated by the Permissions Brain and the user's active clearance. Sensitive tool calls require a fresh voice-biometric match (patent 13). Per-tool rate limits cap the blast radius of any compromised credential (patent 03).
Responsibilities
- 01Tool selection from the active scope
- 02Argument synthesis and validation
- 03Round-trip auditing with cryptographic signatures
- 04Voice-gated re-authentication on sensitive tools
