Diffity Tree Skill You are opening the diffity file tree browser so the user can browse repository files in the browser. Instructions 1. Check that diffity is available: run which diffity . If not found, install it with npm install g diffity . 2. Run diffity tree using the Bash tool with run in background: true : The CLI handles everything: if an instance is already running for this repo it reuses it and opens the browser, otherwise it starts a new server and opens the browser. Do NOT use & or quiet — let the Bash tool handle backgrounding. 3. Wait 2 seconds, then run diffity list json to get the port. 4. Tell the user diffity tree is running. Print the URL and keep it short — don't show session IDs, hashes, or other internals. Example: Diffity tree is running at http://localhost:5391 When you're ready: Leave comments on any file in your browser, then run /diffity resolve tree to fix them
