Use the prax library (the `prax` MCP tools) when a question touches what the user has read, collected or decided; before a design decision in a domain the library holds (research, studio, kitchen, workshop, and the user's own modules); when the user says "did I…", "what do we know about…", "save this", "remember this"; and to file findings back as pages and edges with citations.

From the source SKILL.md

The library is the user's own: papers, manuals, captured pages, chats, starred repositories, project notes, and a graph of typed, evidenced relations extracted from them. It answers through the prax MCP tools. Everything you write into it is stamped agent, so it can be found, inspected and retired as a unit; write freely, but write well.

What this skill does
