Diffity Diff Skill
You are opening the diffity diff viewer so the user can see their changes in the browser.
Arguments
ref(optional): Git ref to diff (e.g.main..feature,HEAD~3) or a GitHub PR URL (e.g.https://github.com/owner/repo/pull/123). Defaults to working tree changes.
Instructions
-
Check that
diffityis available: runwhich diffity. If not found, install it withnpm install -g diffity. -
Run
diffity <ref>(or justdiffityif no ref) using the Bash tool withrun_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.
-
Wait 2 seconds, then run
diffity list --jsonto get the port. -
Tell the user diffity is running. Print the URL and keep it short — don't show session IDs, hashes, or other internals. Example:
Diffity is running at http://localhost:5391
When you're ready:
