Introduction

PR Review Kit is an open-source framework that brings structured, multi-perspective AI code review directly into your repository. It runs entirely inside your AI IDE — no server, no external API calls, no data leaving your machine.

What is PR Review Kit?

Instead of one generic AI review, PR Review Kit runs a team of specialist agents — each focused on a different dimension of your code. The result is a structured, actionable review covering logic, security, performance, architecture, and business impact.

The framework installs into your project as a _prr/ folder. Agents and workflows are plain Markdown and YAML files that your AI IDE reads and executes. There is no background process, no webhook, and no subscription.

Key features

  • 100% local — code never leaves your machine. Safe for NDA projects and corporate environments.
  • Free forever — MIT license, no subscription, no usage limits, unlimited repos.
  • Five specialist reviewers — General, Security, Performance, Architecture, and Business Review.
  • Works with 18+ AI IDEs — Claude Code, Cursor, Windsurf, GitHub Copilot, and more.
  • All major platforms — GitHub, GitLab, Azure DevOps, and Bitbucket. Or run locally with no CLI.
  • Open source and extensible — every workflow is a Markdown or YAML file you can fork and adapt.

Quick start

Run the installer in any project directory:

npx prr-kit install

The interactive installer asks a few questions — your name, preferred language, platform repo, and IDE — then writes everything to _prr/prr/config.yaml. No manual file editing required.

Then open your IDE in the installed project and run one of these commands to start:

  • /prr-quick — one command, full pipeline (select PR → review → report)
  • /prr-master — full menu with all options
Note: The exact command depends on your IDE — not all IDEs use slash commands. See IDE Support for the command specific to your IDE.
Silent install: add --yes to skip all prompts and use defaults.
npx prr-kit install --directory /path/to/repo --modules prr --tools claude-code --yes

How it works

After installation, open your project in your AI IDE and run /prr-quick for the fastest path — it runs the full pipeline automatically: select PR, collect context, run all reviewers, and compile a report. Or use /prr-master for the full menu with individual step control.

All processing happens through your IDE's built-in AI. No additional API key is required beyond what your IDE already uses.
