Quick Review

Exceptional skill that applies TDD methodology to documentation creation with comprehensive testing frameworks. The description clearly indicates use for 'creating new skills, editing existing skills, or verifying skills work before deployment.' SKILL.md provides extensive task knowledge including the complete RED-GREEN-REFACTOR cycle, pressure testing methodologies, CSO optimization, rationalization tables, and concrete examples. Structure is well-organized with clear sections, though at ~3000 words it's dense (intentionally comprehensive for a meta-skill). References to testing-skills-with-subagents.md, anthropic-best-practices.md, persuasion-principles.md, and render-graphs.js are appropriately treated as present. Novelty is high: applying TDD to process documentation with subagent pressure testing is sophisticated and would require extensive token usage if done ad-hoc. The Iron Law ('NO SKILL WITHOUT A FAILING TEST FIRST') and systematic rationalization-plugging represent genuinely novel approaches to documentation quality. Minor density concerns are appropriate given this is a foundational meta-skill for creating other skills.
