Overview

What is Caliber?

Caliber is an open-source command-line tool that scans your codebase and generates tailored configuration files for AI coding assistants. One command gives Claude Code, Cursor, GitHub Copilot, and Windsurf the context they need to write better code in your project.

The problem Caliber solves

AI coding assistants work best when they understand your project — your conventions, your stack, your patterns. Without that context, they produce generic code that doesn't match how your team works.

Manually writing config files like CLAUDE.md or .cursorrules is tedious and they go stale as your project evolves. Caliber automates this entirely: it reads your code and produces configs that reflect your actual codebase.

What Caliber generates

• CLAUDE.md — project instructions for Claude Code with conventions, architecture, and setup commands. Learn more →
• .cursorrules — coding rules and patterns for Cursor AI. Learn more →
• Skills & AGENTS.md — reusable capabilities and agent definitions for Claude Code.
• MCP server configs — recommended Model Context Protocol servers for your stack. Learn more →

How it works

Caliber detects your frameworks, test runners, linters, CI/CD setup, and coding patterns. It supports JavaScript, TypeScript, Python, Go, Rust, Java, and more. Configs update automatically as your project evolves.

Open source and private

Caliber is MIT-licensed and runs entirely on your machine. No code leaves your computer, no accounts required, no usage limits. Install it and run caliber init in any project to get started.
