Installation

PR Review Kit installs into your existing project repository. The installer is a one-command interactive setup that handles everything automatically.

Requirements

Requirement	Version	Notes
Node.js	20 or later	Required to run the installer
Git	Any recent version	Required for diff generation
AI IDE	Any supported IDE	See IDE Support
Platform CLI	Optional	Only needed for PR listing and posting comments

Platform CLIs are optional. Without them, reviews still run using git diff locally — findings are saved to _prr-output/reviews/ instead of being posted to your platform.

Interactive install

Run this from your terminal inside the repository you want to add reviews to:

npx prr-kit install

The installer will ask:

Your name — used in review reports
Language — language for reviewer agent responses (e.g. English, Vietnamese)
Platform repo — e.g. owner/repo. Leave blank for local mode.
IDEs to configure — select one or more from the list

All values are written automatically to _prr/prr/config.yaml. No file editing needed.

Silent install

Pass --yes to skip all prompts and accept defaults:

npx prr-kit install --directory /path/to/repo --modules prr --tools claude-code --yes

Available flags:

Flag	Description
`--directory`	Target repository path (default: current directory)
`--modules`	Modules to install (e.g. `prr`)
`--tools`	IDEs to configure (e.g. `claude-code,cursor`)
`--yes`	Accept all defaults, skip prompts

What gets installed

The installer creates a _prr/ folder at the root of your repository:

_prr/
├── core/
│   ├── agents/
│   │   └── prr-master.agent.yaml   # Master orchestrator
│   └── tasks/
│       └── workflow.xml            # Workflow engine rules
└── prr/
    ├── agents/                     # Specialist reviewer agents
    ├── config.yaml                 # Your configuration
    └── workflows/
        ├── 1-discover/             # Select PR
        ├── 2-analyze/              # Describe + collect context
        ├── 3-review/               # All reviewer agents
        ├── 4-improve/              # Code improvement suggestions
        ├── 5-ask/                  # Q&A about the PR
        └── 6-report/               # Report generation + post comments

IDE-specific files (agent definitions, workflow files) are also written to the appropriate locations for each IDE you selected.

Next steps

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.
