The Writing Skills skill provides a rigorous framework for developing Claude Code capabilities by treating documentation as code that requires testing. It utilizes a Red-Green-Refactor cycle where authors first observe an agent fail a task (Red), document the skill (Green), and then refine the instructions to close behavioral loopholes (Refactor). This approach ensures that every skill added to a library is necessary, effective, and optimized for Claude's discovery mechanisms through specific Claude Search Optimization (CSO) patterns.
