Let me leave you with a philosophy that changes how you should think about software development with Claude Code.

A bad line in CLAUDE.md is worse than a bad line in a specification, which is worse than a bad line in the research, which is worse than a bad line in the plan, which is worse than a bad line of code.

Think about what this means. Mistakes propagate downstream and get amplified. If your CLAUDE.md file has incorrect guidance, Claude will generate flawed specifications. Those flawed specifications lead to misguided research. That misguided research produces bad plans. And those bad plans result in broken code.

But here's the liberating part: code is now cheap. You can throw it away. It doesn't matter. You can regenerate it in seconds.

What matters is getting the upstream steps right. Your CLAUDE.md needs to accurately capture your project's context and conventions. Your specifications need to clearly define what you're building. Your research needs to explore the right approaches.

With Claude Code, you should focus your human attention on those earlier, higher-leverage steps. Make sure your CLAUDE.md is correct. Make sure your specifications are clear. Make sure your research explores the right questions.

The code itself? That's disposable. Claude can regenerate it as many times as you need. Focus on the decisions that flow downstream into everything else.
