npx skills add https://github.com/kamranahmedse/diffity --skill diffity-treeWhat is this skill?
- Verifies `diffity` via `which diffity` and installs globally with `npm install -g diffity` when missing
- Runs `diffity tree` in the background so an existing repo instance is reused or a new server starts and opens the browse
- Polls `diffity list --json` after 2 seconds to report the localhost URL without exposing session IDs or hashes
- Explicit handoff to `/diffity-resolve-tree` after comments are left in the browser

# 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
