What problem does it solve? Producing original poster artwork requires both a coherent design concept and a working render pipeline; this Skill enforces a disciplined workflow that turns a brief into a written design philosophy plus a finished single-page PNG or PDF, avoiding generic genre-default visuals. ## Core Features & Use Cases - Structured art direction: Forms three candidate directions across seven axes (emotional register, material language, composition topology, typographic voice, color strategy, image mode, central metaphor) and records the selection as an artDirection contract. - Human-in-the-loop gating: Uses request_human_loop to resolve ambiguous visual direction before writing the philosophy, spec, or artwork when the brief lacks explicit style evidence. - Packaged renderer with schema contract: Runs scripts/render_static_canvas.py to load the current schema and render JSON specs with layout families, composition variants, visual motifs, texture, density, and CJK font glyph checks. - Use Case: Given a brief for a city technology event poster, compare three distinct directions, confirm one with the user, write the philosophy, render a 1800x2700 PNG, and inspect the thumbnail silhouette against the chosen topology. ## Quick Start Use the canvas-design skill to create a poster for my product launch, starting by loading the renderer schema and proposing three distinct visual directions for my approval.
