Why Claude Ignores Your Instructions (And How to Fix It With CLAUDE.md) You write clear instructions. Claude reads them. Then it does something completely different. Not wrong, exactly. Just. not what you asked for. It adds docstrings you didn't request. It refactors code you told it to leave alone. It "improves" things that were fine. You correct it, it apologizes, and three prompts later it drifts again. This isn't a bug. It's how large language models process context - and once you understand the mechanism, you can fix it with a single file.
