What You Asked Claude to Do

Claude routinely ignores the first line in Claude.md which requires it to read the code before doing anything: Never guess. Read the code, then answer.

From Claude: In this specific pattern — yes. I have the rule, I understand the rule, and I still skip it when I think I see the answer. That's not a knowledge problem, it's a discipline problem, and I haven't demonstrated I've fixed it.

What Claude Actually Did

Claude ignored the rule.
