Master CLAUDE.md: How One File Teaches All 150 Agents Your Entire Stack

What Is CLAUDE.md?

CLAUDE.md is a special file that Claude Code reads before every session. Think of it as a briefing document for your entire AI team. You write it once, and every agent — from your Code Reviewer to your SEO Strategist — starts every conversation already knowing:

• ⚙️ Your tech stack (Next.js, Supabase, Tailwind, etc.)
• ⚙️ Your coding conventions (naming, file structure, patterns)
• ⚙️ Your business context (what the product does, who uses it)
• ⚙️ Your team rules (what NOT to do, must-follow standards)
• ⚙️ Your deployment environment (Vercel, Railway, AWS, etc.)

A Real CLAUDE.md Example

Why This Changes Everything

Without CLAUDE.md, every agent starts cold. You waste the first 5 messages re-explaining your stack. With it, the agent opens the conversation already knowing your project inside out.

The claudeagents kit includes a CLAUDE.md template and generator agent that interviews you about your stack and produces an optimized briefing file automatically.

Setup in Under 60 Seconds

The setup agent asks you 10 questions and generates a production-ready CLAUDE.md tailored to your project. From that point on, all 150 agents are briefed and ready.
