301 Exercises: The Step Up

Setup

• Claude Code installed and working, with the guidance file you wrote in 102.
• Git and a shell. The examples use zsh, the shell the course's evidence comes from.
• A scratch directory outside any real project, since every exercise runs in throwaway repositories: mkdir -p ~/scratch/301 && cd ~/scratch/301.
• A scratch clone of a project you know, for Exercises 2 and 3: git clone -q <path or URL of your project> clone.
• Intent 3.2.3 or later, for Exercise 2.
• A piece of real work you might give to more than one agent, and the six evaluation framework scores you kept from 104.
• No messages. Exercise 2 registers a roster on a board and sends nothing; 302's exercises pass messages between nodes.
