A folder your AI loads on demand. It answers from the source, and says [NOT IN SOURCE] instead of inventing.

What it is

The method, ready to use.

A short, fixed routine that takes a cited authority and answers four questions: can I open it in a primary source, is it still good law, does it decide this point, and does the paragraph say what is claimed. Anything that fails is deleted or replaced.

Ask

Questions

Before you install.

What exactly is a skill?

A skill is a document 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?

Claude, ChatGPT, Gemini, Copilot and any tool that reads a SKILL.md. Drop the file into your AI of choice — a Claude Project, a ChatGPT Custom GPT, a Gemini Gem, or your tool's skills folder.

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 practice skills are reviewed quarterly, and members can re-download the latest version any time from their dashboard.
