| [references/structure.md](references/structure.md) | Frontmatter, naming, descriptions, progressive disclosure, file layout |
| [references/writing.md](references/writing.md) | Prose rules: terminology, phrasing, conditions, thresholds |
| [references/workflows.md](references/workflows.md) | Step/phase structure, feedback loops, exit signals, output patterns |
| [references/composition.md](references/composition.md) | Depending on, invoking, and fanning out to other skills |
| [references/tools.md](references/tools.md) | Agent, Bash, AskUserQuestion, and MCP tool invocation |
| [references/evaluation.md](references/evaluation.md) | Evaluations and iterating on a skill from observed behavior |
