Thanks for the write up. I'm starting to consider enhancing my setup and building on pi sounds interesting. I have a similar core workflow, but I'm still tied to CC's interface and I can see how it might be nice to have something a bit more custom.
- the smaller context and default-off for thinking make it extremely fast (thinking is a dead-end bitter lesson imo)
- the source is available; and organized specifically to make it easy for agents to write and test extensions. Just launch pi in the pi-mono directory, and it will turn your idea into an extension in no time.
