Model switch guard
Confirm the first prompt after a mid-session model switch, or undo the pending switch before sending anything.
I usually want to stay on the same model for the whole session. Switching models means loading, and paying, for the re-reading of a sessions. In this case, 90% of the time I prefer making a handoff document, so this is a sanity check to make sure I truely want to do this.
Install
pi install npm:@dylanhalstead/pi-model-switch-guardUsage
Select models freely before the first turn starts. After that, changing models shows a status warning. Sending the next non-empty interactive prompt asks whether to use the new model:
- Choose Yes to send the prompt and confirm the switch.
- Choose No or cancel to restore the original model and keep the prompt text in the editor without sending it.
- If restoration fails, the extension shows an error and asks again on the next submission.
Use /model-undo or ctrl+alt+m to undo an unconfirmed switch without sending a
prompt. Undo only applies to pending switches; it does not provide model history.
Switching back to the original model clears the warning.
No configuration is needed. Use Pi's model selector as usual.
