+# Skill Creator
+
+Use when: building a new skill to encode a workflow, process, checklist, or domain expertise that should be reusable across sessions.
+
+## What Makes a Good Skill
+- **Specific trigger** — clear "use when" condition so Claude knows when to invoke it
+- **Process, not just content** — steps to follow, not just reference info
+- **Opinionated** — makes decisions so the user doesn't have to repeat themselves
+- **Testable** — you can tell if it's being followed correctly
+
+## Skill File Format
+
+```markdown
+---
+name: skill-name          # kebab-case, matches filename
+description: One line explaining when and why to use this skill.
+---
+
+# Skill Title
+
+Use when: [specific trigger condition]
+
+## [Section 1]
+[Content]
+
+## [Section 2]  
+[Content]
+
+## Rules / Constraints
+- Hard rules the skill enforces
+```
+
+## Process for Creating a New Skill
+
+1. **Understand the workflow** — ask the user:
+   - What task does this skill help with?
+   - When should it be triggered (what user phrase or situation)?
+   - What are the non-obvious things to remember?
+   - What mistakes does it prevent?
+
+2. **Draft the skill** — write a SKILL.md with:
+   - Clear frontmatter (name, description)
+   - Trigger condition upfront
+   - Step-by-step process OR checklist
+   - Rules/constraints section
+   - Example output if helpful
+
+3. **Save to `~/.claude/skills/<name>.md`**
+
+4. **Test it** — invoke the skill and confirm it produces the right behavior
+
+## Skill Location
+Skills go in `~/.claude/skills/` as individual `.md` files.
+They're invoked with `/skill-name` or detected automatically from the description.
