Description

Timeline Poster Studio transforms history, biography, technology, science, art, cultural change, product evolution, and other time-based subjects into informative and visually distinctive timeline posters. The skill first defines the topic, scope, audience, and time range, then performs focused research only to the level needed for the poster. It curates the most meaningful events, identifies turning points and natural eras, distinguishes exact, approximate, and duration-based events, and detects parallel storylines or geographic movement when relevant. It then builds an adaptive poster structure instead of forcing every topic into the same template or fixed aspect ratio. Depending on the content, the poster may use vertical, tall vertical, horizontal, or wide layouts. Visuals are selected according to their role: narrative scenes can blend naturally into the composition, while artworks, products, objects, documents, maps, and other reference visuals remain clearly organized and controlled. The design system protects chronology, readability, and factual structure while giving the visual AI creative freedom in color, typography, panel design, framing, decoration, background treatment, and overall art direction. For the same verified content, the skill produces three complete standalone poster prompts: Strict Hierarchical Design — optimized for educational clarity and structured reading. Free / Expressive Design — gives the visual AI greater freedom to create a bold and distinctive poster identity. Hybrid Design — balances clear information design with creative visual character. The prompts are designed to work across different image-generation tools, allowing the user to review, modify, or choose a design direction before generating the final poster.
