Before you install.
What exactly is a skill?
A skill is a folder your AI loads on demand: a SKILL.md with the method, reference files, a cheatsheet and a provenance manifest. The model answers from it and replies [NOT IN SOURCE] instead of inventing.
Which AIs does it work with?
This skill installs into Claude Code, opencode, Claude.ai, ChatGPT, Gemini — and any tool that reads a SKILL.md.
Will it answer from the source?
Yes. Every package carries explicit answering rules: cite the section for each claim, label authority vs reasoning, and never invent a figure, citation or rule.
Is it kept current?
Yes. Method and donor skills are reviewed quarterly and you can re-download the latest version from your dashboard.
