WHY THIS IS DIFFERENT
It produces reusable build handoffs, not generic prompts.
- Creates a no-side-effect API sandbox plan for agent testing.
- Exports mock server code, fixtures, API collection, failure matrix, and MCP schema draft.
- Separates allowed sandbox actions from blocked production side effects.
Boundary: Not production API security, authentication implementation, penetration testing, legal approval, or permission to run agents against private systems.
