Translates an image (or a set of image references — screenshots, mockups, Figma URLs, live websites) into two mirrored design-system artifacts: docs/design.md (YAML tokens + prose, following Google's open design.md format, for the coding agent) and docs/design.html (a self-contained, token-driven style guide rendering…
Skill Claude CodeCodex
Guided discovery of a product idea by mining what the founder already knows or already does — covers source selection (business vs. expertise), context capture, pattern synthesis, candidate scorecard, and writes docs/product-idea.md. Use when the founder says "generate an idea", "help me find an idea", "what should I…
Skill Claude CodeCodex
Pressure-tests a product idea before the founder invests in planning, building, or launching. Surfaces fatal flaws, tests whether the problem is real, maps real competition (including current behavior), plans first 10 customers, defines a 2-week MVP test, returns a strong/weak/pivot verdict, then sharpens…
