- Always use background terminals (
isBackground: true) for every command so a terminal ID is returned - Always kill the terminal after the command completes, whether it succeeds or fails — never leave terminals open
- Do not reuse foreground shell sessions — stale sessions block future terminal operations in Codespaces
- In GitHub Codespaces, agent-spawned terminals may be hidden — they still work. Do not assume a terminal is broken if you cannot see it
- If a terminal appears unresponsive, kill it and create a new one rather than retrying in the same terminal
