BF ui-cloner

Analyzes UI screenshots and generates a reusable .skill file that captures the product's complete design system. Triggers when the user provides UI screenshots (single or multiple pages of the same product) and wants to clone, reproduce, or extract a design system from them. Input: one or more image file paths or a directory. Output: a ready-to-install .skill file encapsulating design tokens, component specs, layout structure, visual style, and interaction patterns. The generated skill can then be used (optionally invoking ui-ux-pro-max) to recreate the UI in any target tech stack.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
