Kitty

Kitty is a Chrome extension for github.com. It works on the page you already have open:

• Repo tours. Click the cat on any repository and it walks you through the files worth reading first: README, build setup, entry point, core modules, tests and CI.
• Ask Kitty. A side-panel chat for Git questions. Answers cite the notes and docs they come from. Paste a Git error and it tells you what happened and how to recover.
• Explain this. Select a command, diff or PR text and get a short explanation. Commands are labelled safe, rewrites history or can lose work.
• Learn tab. Short lessons, quizzes, and a practice mode where you can run reset, rebase or a force push against a simulated repo and watch the commit graph.
• Contributing help. Find beginner-friendly issues, get the files and git commands for fixing one, and check your pull request for the usual review comments before you open it.
• On GitHub pages. Hover buttons like Sync fork or Squash and merge to see the git equivalent, ask why a CI run failed, or let the cat point out where things are on the page.

Kitty explains and guides; it doesn't write code. When you ask for code, it hands the request to GitHub Copilot.

Install: download the zip from the latest release, unzip it, open chrome://extensions, turn on Developer mode and choose Load unpacked.

Architecture, local setup and self-hosting are in kitty/README.md.

git add .
git commit -m "feat: your change"
git pull --rebase    # if someone pushed first
