Why it matters

Turns a git change into a guided tour of how a senior engineer would review it. It's for developers who want to understand AI-written or unfamiliar changes, not just merge them.

Highlights

A read-only terminal UI: step through the tour with the arrow keys. It never changes your files or repository.
The tour covers what the change is for, where to spend time, risky cases (failure, double runs, rollback, scale), and which findings must be fixed.
Reviewer "wait" moments are posed as questions so you can predict the answer first.
The tour is written by an LLM CLI you already use (Claude Code, Codex CLI, Gemini CLI, OpenCode 2 or Copilot CLI) and takes 2-5 minutes.
English and Japanese interfaces.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You review a lot of agent-written pull requests and want to learn what to look for.

Worth knowing: An early release; the tour format and screens may change.
