- ๐ Every Shortcut Within Reach A game controller puts hundreds of actions within finger's reach. Here's the math and information theory behind why it works.
- ๐ Backwards Compatible for Life When tests and prompts encode your intent, code becomes a regenerable artifact. Your program survives every platform shift, every language change, every era.
- ๐ป One Repo, Many Agents Git worktrees let you run multiple AI agents on the same codebase without them stepping on each other's toes.
