crev

Interactive code review tool for git diffs. Browse changed files, add inline comments with severity levels, and submit structured JSON reviews.

Built to integrate with Claude Code as a skill — Claude makes changes, you review them in crev, and your feedback goes straight back.

Install

make install

This builds the binary, installs it to ~/.claude/skills/review/, and symlinks crev and crev-web into ~/.local/bin/.

Usage

Web UI (default)

crev --web

Opens a browser-based review interface with syntax highlighting, dark/light themes, resizable sidebar, and inline commenting. Best for detailed reviews.

Terminal UI

crev

Full TUI with vim-style keybindings (j/k navigation, / search). Runs in the terminal via Bubble Tea. Works over SSH and in tmux popups.

Options

-o FILE    Save review JSON to file (default: stdout)
-d DIR     Review a different directory
-staged    Only review staged changes
-json      Raw JSON output (no formatting)
-web       Use browser-based UI

Claude Code Integration

After make install, two integrations are available:

Skill (/review) — Claude automatically launches crev when you ask to review changes. Your comments come back as structured JSON that Claude can act on.

Command (/crev) — Explicitly launch a review session from Claude Code.
