You send TypeSafe's System One model a state and typed questions. About 300 ms later you get typed answers back, with probabilities your code can branch on, for a fraction of a cent. This repo arranges thirty concrete uses of Jev into ten levels. Levels 1 to 5 call Jev from plain code. Levels 6 to 10 put Jev inside the pi coding agent, first as hooks the agent never sees, then as tools the agent chooses to call, until the agent writes the questions itself. Every level runs live against real Jev, and every option is tested. The /install command lives at .claude/commands/install.md. It checks Node, bun, just, git, and pi, installs…
