CLAUDE.md Generator — Create Project Memory for Claude Code

This CLAUDE.md generator helps you build a project-memory file that Claude Code reads automatically at the start of every session. A good CLAUDE.md documents what an AI cannot infer from the code alone — your tech stack and versions, build and test commands, code-style conventions, project structure, and guardrails — so the assistant follows your rules without being reminded and uses fewer tokens. Keep it tight: prune anything obvious, and add a rule whenever you correct the assistant on the same thing twice.

Step 1 — Choose framework
Step 2 — Add stack options
Step 3 — Copy your CLAUDE.md

What is CLAUDE.md and why does it matter?

CLAUDE.md is a project context file read by Claude Code at the start of every session. It tells Claude your stack, conventions, commands, and constraints — so you stop re-explaining them in every chat. A good CLAUDE.md cuts prompt overhead by 30–50% and dramatically improves Claude's first-attempt accuracy on your codebase.

Place it at your repo root. Claude Code reads it automatically. The file uses Markdown and supports any instructions: which files to avoid editing, which patterns to always follow, which dependencies to prefer, and what the project actually does. Think of it as onboarding documentation written specifically for your AI pair programmer.

Frequently asked questions

What is CLAUDE.md?

It is an instruction file containing build commands, test commands, and coding conventions that AI coding assistants read on startup.

Where should I save CLAUDE.md?

You should save it directly in the root directory of your git repository.

What a good CLAUDE.md contains

A CLAUDE.md file is project memory for Claude Code: instructions it reads automatically at the start of every session, so you don't re-explain your conventions in each prompt. The payoff is consistency — the assistant follows your rules without being reminded, and uses fewer tokens doing it.

The highest-value sections describe what an AI can't infer from the code alone: your tech stack and versions, build and test commands, code-style conventions (naming, formatting, patterns you favour or ban), the project structure, and any guardrails ("never edit generated files", "always run the linter before committing"). Concrete examples beat abstract rules — show one correct pattern rather than describing it.

Keep it tight. A bloated CLAUDE.md wastes context on every request, so prune anything obvious from the code or rarely relevant. Treat it as living documentation: when you find yourself correcting the assistant on the same thing twice, that correction belongs in the file. Place it at the repo root for project-wide rules, or in a subdirectory for folder-specific ones.
