Your CLAUDE.md is the most important file you're not using

Tell Claude who you are — once. It reads your CLAUDE.md before every conversation, so it stops treating you like a stranger.

📄
What is CLAUDE.md?
A file Claude reads at the start of every conversation. It contains your context: who you are, what you do, how you work, what kind of output you need. Think of it like onboarding a new colleague — you only do it once, then they just get you.
Why it matters
Without CLAUDE.md, Claude treats you like a stranger every time. Generic responses, wasted context, constant re-explaining. With a great one, Claude knows your role, matches your tone, and delivers useful work from message one.
🎯
The single biggest lever
Better than any prompt trick or instruction. Describe your work below — we'll build a CLAUDE.md scored for clarity, specificity, tone, and output format. The better your CLAUDE.md, the less you repeat yourself and the smarter Claude gets.
Never set up a CLAUDE.md? Describe your work and we'll create one that makes Claude understand you from the first message.
🎉 You're all set! Now you can optimize your instructions below.

Tell us how you work, and we'll build your CLAUDE.md. Save it with your files or paste it into Claude, and Claude will know exactly how to help you — from the very first message.
