Exploring a more deterministic approach to AI-assisted code generation

Introduction AI coding agents are getting surprisingly good. In small projects, you can ask them to add features, fix bugs, and even write tests—and they often succeed. But once your project grows, things start to break down. In my experience, the issue is not model capability. It’s something more subtle: prompt instability . The Problem: Prompt Instability Most coding agents construct prompts dynamically using: chat history parts of the codebase internal heuristics This means the final prompt i
