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.
Paste 1–3 real Claude conversations and get a full diagnostic of your prompting patterns + a CLAUDE.md built from your actual behavior.
Tell Claude about your work
Paste 1–3 Claude conversations

Include both your messages and Claude's responses. We'll diagnose your prompting patterns and build a CLAUDE.md from your actual behavior — not self-reporting.

Paste your bloated CLAUDE.md

Files over 2,000 tokens risk Claude skimming or deprioritizing sections. We'll cut everything low-signal, tighten the language, and get you under the limit — without losing what makes it yours.

🎉 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.
