# Writing Skills ## Overview Skill development has two phases: **drafting** (this skill) and **evaluation** (`slow-powers:evaluating-skills`). This skill is your template for authoring a new skill and your checklist for auditing an existing one — it covers structure, building blocks, description writing, and rationalization-proofing. A behavioral draft you didn't measure is a claim you didn't verify. After drafting, hand off to `slow-powers:evaluating-skills` to decide whether the change is behavior-shaping (measure it) or deterministic instruction-following (declare the decision and reasoning, then skip). Default to measuring; the skip is a narrow, announced exception, not an escape hatch. ## Validation checklist Use your persistent task tracker — one task per item. Works for authoring a new skill or auditing an existing one — copy it into your tracker before you start, then work through the rest of this skill against it. **Draft:** - [ ] Name uses only lowercase letters, numbers, hyphens - [ ] Frontmatter has `name` and `description` (under 1024 chars total) - [ ] Description starts with "Use when…", is third person, includes triggers/symptoms, and contains NO workflow summary - [ ] Body keeps to one excellent example per concept; no narrative-of-one-session content - [ ] Companion files use the correct directory from "Skill directory layout"; principles stay inline - [ ] Flowcharts only for non-obvious decisions/loops/branches; semantic labels, no code - [ ] An
