SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides the creation of effective, robust AI skills by applying Test-Driven Development principles to documentation. It ensures skills are clear, comprehensive, and resilient against agent rationalization.

Core Features & Use Cases

TDD for Documentation: Uses subagents to test skill effectiveness, following a Red-Green-Refactor cycle.
CSO (Claude Search Optimization): Provides guidelines for naming, descriptions, and keywords to maximize skill discoverability.
Use Case: When developing a new AI skill, use this skill to systematically test it with subagents, identify loopholes, and refine its language until it's bulletproof against misinterpretation or rationalization.
