"""Comprehensive mock agent test harness for triage_sdk.

What this script validates:
- Input checks (benign and jailbreak-like prompts).
- Full agent flow: input -> tool-call -> output checks.
- Direct tool-guard stress tests with dangerous actions.

Auth is currently not enforced server-side, so the API key is only for SDK wiring.
