Caliber vs rule-porter
A side-by-side comparison of two Command-line AI agents — to help you pick the right one.
Caliber
Caliber is an open-source command-line tool that analyzes codebases and generates configuration files for AI coding assistants like Claude Code, Cursor, and Codex. It evaluates the setup quality with a 0–100 score and suggests compatible MCP (Model Configuration Protocol) servers for optimization.
rule-porter
rule-porter is a command-line tool designed to convert AI IDE rule files between formats used by Cursor (.mdc), CLAUDE.md, AGENTS.md, Copilot, and Windsurf. It supports bidirectional conversion and provides warnings for lossy transformations during the process. The tool is zero-dependency, making it lightweight and easy to integrate into workflows.
