Introduction
The configuration console for all your AI coding harnesses.
Harness Kit
Harness Kit is the configuration console for all your AI coding harnesses.
Every AI coding tool has its own setup folder — Claude Code's ~/.claude, Cursor's .cursor, Copilot's config. Different names, same shape, totally incompatible. harness-kit is the layer that turns all of them into one setup you carry with you: plugins, skills, MCP servers, hooks, and conventions, all declared in a single harness.yaml.
Configure once. Observe what your AI actually does. Share your setup with a teammate in one file.
