ratstack

Learn rat-stack one concept at a time, without a checkout.

ratstack runs the local learn commands and an MCP server. Progress and display preferences stay in ~/.rat-learn on your machine. Set RAT_LEARN_DIRECTORY to use another directory. The public concept deck comes from https://ratstack.sh.

Commands

npx ratstack learnNext
npx ratstack learnRecord --event '{"conceptId":"lore.context-and-requirements","kind":"shown"}'
npx ratstack learnPreferences
npx ratstack learnSetPreferences --width wide
npx ratstack mcp

npx ratstack --help lists every command and flag.

MCP

Add the server to an MCP client:

{ "command": "npx", "args": ["-y", "ratstack", "mcp"] }

The server exposes the local learn tools only.
