SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generates poster-ready images quickly by turning briefs into polished visuals, saving time and enabling rapid iteration on design concepts.

Core Features & Use Cases

  • One-image-per-turn workflow: Produces a finished poster asset per turn unless variations are requested.
  • Provider-agnostic workflow: Operates with the active upstream image model (e.g., gpt-image-2) through the shared media tooling.
  • Structured prompt assembly: Builds a prompt from the user brief (subject, composition, lighting, palette, and avoidance notes) for reliable results.
  • Use cases: Editorial posters, event visuals, and marketing artwork created from short briefs.

Quick Start

Provide a brief design prompt and run the poster workflow to generate a PNG/JPEG asset saved in your project folder.
