    "name": "preview-shots",
    "description": "Open image shots (screenshots, snapshot baselines, montages, renders) in ONE macOS Preview window so the user can eyeball them. Use when the user asks to open \/ show \/ pull up \/ review shots in Preview or Finder, or right after producing visual artifacts the user should look at before signing off."

Preview Shots

Put the review-worthy images in front of the user in a single Preview window they can flip through.

Workflow

Curate the set — the images that answer "is this right?": the just-changed or just-blessed baselines, the integrated result, and the reference image when there's something to compare against. Don't dump every PNG in the folder; pick the smallest set that lets the user judge the change. If the user named specific shots, open exactly those.
One window — open them with a single open -a Preview <path> <path> ... call. One open invocation lands all the files in one window with a thumbnail sidebar; separate calls spawn separate windows.
Caption them — list one line per shot (what it is) so the user knows what they're flipping through.

Rules

macOS only (open); pass absolute or repo-root-relative paths.
Order the files most-important-first; the first one is what Preview shows on open.
Review saved PNG/GIF artifacts, not live Chrome. Exact regression capture should run headless by default; only open Chrome when the user explicitly asks for a live browser or when reproducing a headful-only bug.
One set at a time — never pile up windows. Before opening a new set, close any open ones: osascript -e 'tell application "Preview" to close every window'.
Close on unattended proceed. When you opened shots for a non-blocking review and then move on without the user's response, close Preview afterward: osascript -e 'quit app "Preview"'. An overnight autonomous run must never wake the user to a wall of Preview windows — at most one set open, and none once you've proceeded past the checkpoint.
