Create a Banner Image

Turn raw window screenshots into a polished horizontal banner — the kind you'd put at the top of a GitHub README or a marketing page. The agent trims, aligns, and tiles them while preserving the shadow and transparency macOS adds automatically.

Bring your own screenshots; the agent handles spacing, sizing, and the composite output.

What to expect

  • You provide window screenshots saved to disk.
  • The agent reads them, normalizes dimensions, and stitches them side-by-side.
  • You get a single banner image ready to embed.

Run it

Paste this into your agent:
