- GitHub lacks a way for agents to show work; capture screenshots as you work, which are staged for the branch, and when a PR opens, it's furnished with a comment.
- Uploads can carry custom tags using --meta; use 'uploads find' to retrieve them by tag, organizing visuals by app part or form factor.
- Uploaded files on a branch stage automatically; 'uploads staged' shows queued items and re-running updates the same comment without breaking embedded URLs.
- Features include device frames (e.g., phone, browser, iPhone), one-shot screenshots of URLs, and shareable galleries that can span multiple PRs.
- To set up, paste the prompt into a coding agent or read the full guide.
