/chat-mode

Switches persistently (sticky) to any chat mode, given as an argument by name.

/chat-mode <mode> switches the active mode for all following messages, e.g. /chat-mode code or /chat-mode architect. The commands /code, /ask and /architect do the same when called without a prompt; /help without a prompt only shows the basic help and does not switch the mode.

✅ WHEN TO USE IT?

Set the mode from a loaded command file

/chat-mode ask inside a file that gets read with /load, to set the mode consistently before further commands run

⛔ WHEN NOT TO?

Directly targeting one of the known modes

code/ask/architect have their own shorter commands with the same effect when called without a prompt.

Better: Use /code, /ask, or /architect directly
