I guess that the most important potential "secret sauce" for a coding agent would be its prompts, but that's also one of the easiest things to find out by simply intercepting its messages.
The only real secret sauce is the training methods and datasets used for refining harness usage. Claude Code is a lot better than gemini-cli/open-code/etc because Claude is specifically trained on how to run in that environment. It's been rlhf'd to use the provided tools correctly, and know the framework in which it operates, instead of relying solely on context.
