Generate and maintain Claude Code skills from the Trail of Bits Testing Handbook.
## When to Use
**Invoke this skill when:**
- Creating new security testing skills from handbook content
- User mentions "testing handbook", "appsec.guide", or asks about generating skills
- Bulk skill generation or refresh is needed
**Do NOT use for:**
- General security testing questions (use the generated skills)
- Non-handbook skill creation
## Handbook Location
The skill needs the Testing Handbook repository. See [discovery.md](discovery.md) for full details.
**Quick reference:** Check `./testing-handbook`, `../testing-handbook`, `~/testing-handbook` → ask user → clone as last resort.
**Repository:** `https://github.com/trailofbits/testing-handbook`
