AI Agent Config Generator

Generate config files for AI coding agents — CLAUDE.md, .cursorrules, copilot-instructions.md, .windsurfrules, and AGENTS.md.

Conventions

CLAUDE.md

Features

  • Generate config files for 5 AI coding agents at once
  • Supports Claude Code (CLAUDE.md), Cursor (.cursorrules), GitHub Copilot, Windsurf, and Codex (AGENTS.md)
  • Pick your framework, language, styling, package manager, and test runner
  • Toggle coding conventions with checkboxes
  • Quick-start presets for common stacks (Next.js, React + Vite, Astro, Express)
  • Copy individual files or all configs at once

How to Use

  1. 1Choose a preset or manually select your tech stack from the dropdowns
  2. 2Toggle the coding conventions that match your project style
  3. 3Switch between tabs to preview each config file
  4. 4Copy individual files with the copy button next to the filename
  5. 5Use "Copy All" to get every config file in one clipboard paste

Examples

Next.js + TypeScript project

Input

Framework: Next.js | Language: TypeScript | Styling: Tailwind | PM: npm

Output

Generates CLAUDE.md, .cursorrules, copilot-instructions.md, .windsurfrules, and AGENTS.md with your stack details, conventions, and commands.
Express API backend

Input

Framework: Express | Language: TypeScript | Testing: Jest | PM: npm

Output

Generates config files with backend-focused conventions, no styling section, and test commands included.

Why Generate AI Agent Config Files?

AI coding assistants like Claude Code, Cursor, GitHub Copilot, Windsurf, and Codex all support project-level configuration files that tell the AI about your tech stack, coding conventions, and project structure. These files dramatically improve the quality of AI-generated code by giving the assistant context it would otherwise have to guess.

Each tool uses a different filename — Claude Code reads CLAUDE.md, Cursor looks for .cursorrules, GitHub Copilot checks .github/copilot-instructions.md, Windsurf reads .windsurfrules, and OpenAI Codex uses AGENTS.md. The content is largely the same: what stack you use, how you want code formatted, and what commands to run. This tool generates all five files from a single set of inputs.

Without a config file, AI assistants default to generic patterns that may not match your project. They might suggest npm when you use pnpm, write class components when you use functional ones, or add semicolons when your codebase omits them. A config file eliminates these mismatches from the start.

Presets let you generate configs instantly for common stacks. If you are starting a new Next.js project with TypeScript and Tailwind, one click gives you production-ready config files for every AI assistant your team might use. You can then customize the conventions to match your specific style.

All generation happens in your browser. Your project details and conventions are never sent to any server. The generated files are standard Markdown that you can edit further before committing to your repository.
