We might be talking past each other here. The point of codemode is to orchestrate the LLM side tool calls, not to orchestrate scripts that it might execute within Bash.

In a world where brain and hand are on different machines, getting the bash hands to reach back into the harness brain is something that requires a) putting tools in its hands that it does not know about b) are tricky to set up, usually involving some sort of socket based back channel.

I tried this quite a bit, by having pi be always there on the hands side, but it causes a lot of complexity and the LLMs really do not understand it well at all.
