I was thinking about this too, but the problem is that different models need to be prompted differently for better performance.

Claude is the best model for tool calling, you might need to prompt less reliable models differently. Prompt engineering is really hard, a single context for all models will never be the best IMO.

This is why Claude Code is so much better than any other agentic coding tool, because they know the model very well and there is an insane amount of prompt engineering went into it.

I tried GPT-5 with OpenCode thinking that it will be just as good, but it was terrible.

Model-specific prompt engineering makes a huge difference!
