This is meta-tooling for building other PCL skills. It walks you through domain analysis, generates skill scaffolding with proper YAML frontmatter, and organizes everything from fundamentals to advanced patterns. You get structured templates for extracting knowledge, categorizing code examples by complexity level, and mapping dependencies between skills. The TypeScript interfaces show the framework pretty clearly: domain analysis, pattern extraction, troubleshooting guides, the works. Honestly most useful if you're creating multiple skills and want consistency, or if you're new to PCL and need guardrails. The structure generator handles the boilerplate so you can focus on the actual domain expertise.
