# Skills One skill per CI Server area, following `knowledge/document-map.md`. Nested skill folders are not used for grouping; group tasks inside each skill instead: ``` / ├── SKILL.md # frontmatter (name, description with task keywords) + task index ├── tasks/ # one file per task └── reference/ # area-specific details ``` The `description` in `SKILL.md` decides when Claude uses the skill. List the words users will actually say.
