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
