Commands, workflow shapes, and shortcuts — adapted to your selected tool.
Start here if you want the shortest path: how this tool works, what matters first, and what to ignore until later.
For Claude Code, the command catalog is not an analogy. It is the real control surface for many of the level jumps described elsewhere on the site.
When you forget a command, shortcut, or workflow shape, come here first instead of reconstructing it from memory.
A command is most useful when the repo already contains the rules and context that make the command worth running.
As you move up levels, commands stop being shortcuts and start becoming the building blocks of repeatable systems.
