How to tour uncommitted changes before you commit them with Diff Tour

Read your own uncommitted work as a guided tour to catch risks before others review it.

Who it is forA developer or AI-assisted coder who has edited files and wants a second read on the change before it is committed.

The problemUncommitted edits are easy to skim past, and the reasons for risky choices are not written down anywhere.

The outcomeA tour of the uncommitted change, including untracked files that are not ignored, showing what to fix and what is fine.

What you need first

  • git installed
  • One of Claude Code, Codex CLI, Gemini CLI, OpenCode or Copilot CLI, installed and signed in
  • A git repository with a change to tour

Steps

  1. Run cd your-repo
  2. Run tour
  3. Pick the uncommitted changes from the list and press Enter (inferred from the README: uncommitted changes can be toured)
  4. Wait 2 to 5 minutes while the tour is written
  5. Press → and ← to step through, and q to quit

Prompt for your agent

In the repository at <path>, run tour on the uncommitted changes and report which files the tour points to first. Expected output: a list of file names from the tour. Verify with `git status` that the working tree is unchanged after the run.

Caveat. Only tracked files and untracked files that are not in .gitignore are sent to the LLM, so check that nothing sensitive is left unignored before you run it.
