Anthropic just dropped new context engineering rules for Claude 5-gen models. The old playbook is dead. Top 5 things to do right now 🧵
5/5: Keep CLAUDE.md lightweight. Repo-specific gotchas only. Point to skills, don't stuff everything in. Bonus: run /doctor in Claude Code to auto-strip dead context.
4/5: Replace rules with principles. "Never write multi-line comments" → "match surrounding code style." Let the model use judgment.
Just a random @fdotinc Friday with @JasonDClinton

@LoupWang @fdotinc @hthieblot @k_taro56v2 @youraidouble Wear the @vovy_ai mascot all day
A startup with a mascot and a dog is undeniably on trajectory to be a unicorn by Series B
My technical co-founder goes where I go.
