### Authoring or modifying a skill
**You own the skill's voice.** Agent-facing prose has a higher bar than human prose; unhelpful sentences become instructions.
1. Use the active host's **skill-creator** skill when available. Otherwise follow the open agent skill format directly.
2. Validate the skill: frontmatter has `name` and `description`, referenced files exist, cross-skill links resolve.
3. Test cases if structural; skip if subjective.
4. Run **Opening a PR**.
When in doubt, delete; prose earns its keep by changing a decision. Tell it to do the thing and skip the reason. Explain only when the rule is confusing without one. Match tone to scope. Point at structural sources (types, READMEs, config); hardcoded details go stale (the **encode-lessons-in-structure** principle skill). Delegate to other skills by path; don't restate. A workflow you keep hitting but isn't captured → propose a new skill.
**Reply:** summary of the skill, key design decisions, validation notes.
