Mithril — CLI — The Fellowship's Voice

chat_core.rs centralizes ALL command logic. REPL and TUI are thin rendering layers that call ChatCore.

ALL command logic lives in one place. Both the REPL and TUI call into it:

ChatCore::execute_command("/help") → returns ChatAction::Message(...)
ChatCore::process_message("fix the bug") → calls orchestrator → returns ChatAction::Response(...)

Frontends only render the result. Adding a command means touching ONE file.

/exit /clear /compact /fellowship /undo /redo /plan /build /session /history /share /telegram /help
