| Action Complexity Authorization Security Tests (SECU-02.2). | |
| Comprehensive tests for action complexity level enforcement: | |
| - Level 1 (LOW): search, read, list, get, summarize, present_chart | |
| - Level 2 (MODERATE): analyze, suggest, draft, generate, stream, submit | |
| - Level 3 (HIGH): update, submit_form, send_email, create, post_message | |
| - Level 4 (CRITICAL): delete, execute, deploy, payment | |
| These are CRITICAL security tests ensuring complexity-based gating. | |
| Failure indicates agents can perform high-risk actions without proper maturity. | |
