Install

Review Raven is a plugin for Claude Code, Codex, GitHub Copilot CLI and VS Code. It runs on Linux x86_64, macOS on Apple Silicon and Windows x86_64.

Claude Code​

Inside a session:

/plugin marketplace add karottenreibe/review-raven-marketplace
/plugin install review-raven@review-raven-marketplace
/reload-plugins

Or from a shell:

claude plugin marketplace add karottenreibe/review-raven-marketplace
claude plugin install review-raven@review-raven-marketplace

GitHub Copilot CLI​

Copilot CLI reads the same marketplace:

copilot plugin marketplace add karottenreibe/review-raven-marketplace
copilot plugin install review-raven@review-raven-marketplace

This also installs it for GitHub Copilot in VS Code.

Codex​

Codex reads the same marketplace:

codex plugin marketplace add karottenreibe/review-raven-marketplace

Then enable Review Raven in /plugins inside a session.

First run​

The plugin ships no binaries. On first use it downloads the archive for your platform from the marketplace's GitHub releases, verifies it against the checksum stored in the marketplace Git repo, and caches it under ~/.cache/review-raven/<version>/ (on Windows, %USERPROFILE%\.cache\review-raven\<version>\).

To install the binary by hand, download the archive for your platform and extract it. It contains a single file, review-raven or review-raven.exe.

After the first run, Review Raven needs no network. Reviews, diffs and comments stay on your machine.
