npx claudepluginhub adilp/crit-diffSide-by-side code review TUI with vim navigation. Leave inline comments in crit-compatible .crit/ format, then let Claude address feedback automatically.
adilpA full-screen, side-by-side diff viewer with vim-native navigation. A companion to crit — the excellent terminal review tool for markdown documents.
Where crit handles document review (plans, specs, markdown), cr handles git diff review (code changes across files) with a GitHub-style side-by-side TUI. Both tools share the same .crit/ comment format, so they work together seamlessly as part of the same review ecosystem.
We recommend installing both for the full workflow — crit for reviewing what Claude writes, cr for reviewing what Claude changes.
cr is available as a Claude Code plugin. Add the marketplace and install:
/plugin marketplace add adilp/crit-diff
/plugin install cr
Then use /cr:review <ref> to open the TUI. After you close it, Claude reads your comments and edits the code to address them.
go install github.com/adilp/crit-diff@latest
Make sure $GOPATH/bin (defaults to ~/go/bin) is in your PATH:
export PATH="$PATH:$(go env GOPATH)/bin"
If you prefer not to use the plugin, you can install the Claude Code skill directly:
cr setup-claude # Install globally (~/.claude/skills/)
cr setup-claude --project # Install for current project only
cr setup-claude --force # Overwrite existing installation
Then use /cr-review <ref> in Claude Code.
If you're not already in tmux, start one before launching Claude Code:
tmux new -s work
# Now launch Claude Code inside this tmux session
claude
If you forget, cr will tell you — but the split-pane review won't work outside of tmux.
# Review working tree changes (staged + unstaged)
cr
# Review changes against a branch
cr main
# Review last N commits
cr -1
cr -3
# Review a commit range
cr HEAD~5..HEAD
cr v1.0..v1.1
# Review only staged changes
cr --staged
# Filter to specific paths
cr main -- src/services/
# Output review comments as JSON
cr status
/cr-review main # review changes against main
/cr-review -3 # review last 3 commits
/cr-review --staged # review staged changes
Workflow:
c, quit with qcr status and addresses them automaticallyWhen running inside tmux, you can open the TUI in a side-by-side split pane:
# Open review in a tmux split and return immediately
cr --detach main
# Open review in a tmux split and block until it closes
cr --detach --wait main
This is how the Claude Code skill invokes cr — --detach --wait is a single blocking call that opens the TUI next to Claude Code and waits for you to finish reviewing.
All keybindings are configurable via ~/.config/cr/config.toml.
