    AI_CHAT_HOME: Command = ...

    Returns to the chat overview (home view) by starting a fresh, empty session. Programmatic callers (e.g. the coder agent's "Start new chat" link, the token-usage warning, the Claude Code /clear mapping) reuse this command since starting a new chat also lands the user on the overview.
