Every skill states when not to use it, not only when to.
103 Methodology Skills in One Fixed Structure
Added 2026-08-06103 skills across 16 categories, with 490 reference files. Every SKILL.md keeps the same eight sections: when to use, when not to, required inputs, the framework, workflow, failure patterns, output format, references.
Line counts are capped too: 250 for a SKILL.md, 400 for a reference, enforced by a lint script and CI rather than convention. It calls itself a methodology layer, with execution left to the model and to you, and no automation promised. The stack-agnostic claim has one exception: the seven SEO skills depend on the Ahrefs MCP. The showcase is 42 fictional brand sites plus a reference build on real audit data — fictional because client work cannot be open-sourced.
