## What it does

Reach for this skill when you are building or refreshing a set of skills out of Testing Handbook material. It runs in five phases: locate the handbook repository, scan its sections and classify them (tool, fuzzer, technique, domain), produce a plan, generate the files, then validate them and update the README.

Generation happens in two passes. Parallel agents write the body of every skill first, leaving the Related Skills section empty. A second, sequential pass fills in cross-references once all skill names exist, which keeps links from pointing at files that were never created. Templates live in `templates/`, validation in `scripts/validate-skills.py`.

The skill only writes inside `plugins/testing-handbook-skills/skills/`, its own directory and the root `README.md`. Other plugins stay untouched. Sections marked `draft: true`, empty directories and GUI-only tools are skipped, since Claude cannot drive a graphical program. The handbook repo is looked up in `./testing-handbook`, `../testing-handbook` and `~/testing-handbook`; if none exists, the skill asks for a path and clones `https://github.com/trailofbits/testing-handbook` as a last resort.
