Bit more general complaint: I keep seeing projects that use system/user prompts and doesn't let the user override them in any other way than manually modifying the project yourself.

Since models reacts so differently to different prompts, and people have different requirements, I feel like a basic requirement for a generally useful tool using LLMs should at least facilitate overriding both the system and user prompts wherever they're being used.

I remember coming across this with Aider as well, and seeing some things that were out of place (for me) in the prompts, but with no way of changing it, I had to rewire things myself so I could override them.
