Poster Designer

Overview

Poster Designer is a unified poster generation skill that always outputs one final poster image, while internally selecting the appropriate generation strategy.

Unlike soft, heuristic-based tools, this skill enforces hard routing rules to ensure that information-heavy posters are generated using deterministic layout rather than direct image generation.

The skill supports two internal strategies:

Layout-first (HTML-based) for posters that convey structured information
Image-first (direct image generation) for posters that are purely visual and symbolic

Strategy selection is final and non-negotiable once routing conditions are met.
