A great CLAUDE.md isn’t longer — it’s smarter.

I ignored CLAUDE.md for almost two months after I started using Claude Code seriously.

I figured it was optional flavor text something for people who like tinkering with config files more than they like shipping code. Then I spent an entire Tuesday re-explaining, for what felt like the fortieth time, that our API routes use a specific error-response shape and that we’re on Postgres, not MySQL. That was the day I actually sat down and built one properly. My correction cycles dropped so noticeably in the following weeks that I genuinely felt a little embarrassed about how long I’d waited.
