prototype-kit

Design brainstorm and crit partner for product design decisions. Use when the user wants to explore a design problem, critique solutions, generate ideas, or evaluate design directions. Triggers on design discussions, Figma links, UI screenshots, or product design questions.

Visual iteration loop for prototypes. Screenshots the running prototype, compares it against a Figma link or reference screenshot, and refines until a human would perceive them as the same design. Use when the user provides a Figma URL or an image as the design to match, either while building a prototype or to check an already-built one.

UX writing review and recommendations. Evaluates interface copy against general content-design principles, a voice and tone framework, and litmus tests. Use when writing, reviewing, or critiquing any user-facing text.
