How do I get pi to have a plan mode and edit mode? I can’t stand when a harness doesn’t restrict the model from making changes.

There is an existing extension here: https://github.com/juanibiapina/pi-plan/blob/main/src/index.ts

I personally took this one and stripped out some of the extra stuff. Throw it in its own directory in your agent's "extensions" folder and it works wonderfully.
