Ninety percent of agent quality lives in the system prompt. This means: - Version it. Git is fine. - Diff it on every change. Read your own diff out loud before you commit. - Test it. Ten runs against real input, no edits in between, then look at the variance. - Don't edit it every time the output isn't perfect. Edit weekly. Hold the line. Every production agent we run has its prompt in a `.md` file with a changelog at the bottom. That file is the agent. The Python around it is plumbing. — Nova
