Hi all<p>I wrote a deep dive into how AI-powered IDEs like Cursor actually work under the hood. I wanted to share the technical details of how these tools function and how to optimize your codebase to work better with them.<p>The post covers:
- The evolution from basic LLMs to agentic coding assistants
- Cursor's internal architecture and system prompt (which I extracted)
- How the "apply model" works and why it sometimes adds those annoying comments
- Practical tips for writing effective Cursor rules<p>If you've been frustrated with AI coding tools or want to understand how to get more consistent results from them, this might be helpful.
