## About

# Skill Creator Guide

This skill teaches you how to create, test, package, and distribute AI agent skills following the standard Agent Skills format.

## How to use this skill

1. If the user asks about **basic concepts or structure** → read `references/structure.md`
2. If the user asks about **frontmatter or description** → read `references/frontmatter.md`
3. If the user asks about **writing style or patterns** → read `references/writing.md`
4. If the user asks about **testing, evals, or iteration** → read `references/testing.md`
5. If the user asks about **packaging or distribution** → read `references/distribution.md`
6. If the user asks about **repo architecture or marketplace** → read `references/repo-architecture.md`
7. If the user asks to **scaffold a new skill** → run `python scripts/scaffold.py  --category `

## Quick reference checklist

- [ ] Choose a kebab-case name matching the directory (max 64 chars, lowercase + hyphens only)
- [ ] Write frontmatter with `name` and `description` (include trigger contexts, desc ≤ 1024)
- [ ] Optionally add `compatibility` (≤ 500 chars), `license`, `metadata`, `allowed-tools`
- [ ] Keep SKILL.md under 100 lines — use `references/` for detailed content
- [ ] Write in imperative tone, explain the why, include examples
- [ ] Add at least one Python script to `scripts/` (no external deps)
- [ ] Create `evals/evals.json` with test prompts
- [ ] Run validation: `python3 tools/validate-all.py` from repo root
