AB design-md-generator
Generate DESIGN.md files from any website URL. Extracts the complete visual design system — colors, typography, spacing, components, shadows — into a structured markdown document that AI coding agents can read to produce pixel-perfect, visually consistent UI. Use when asked to "extract design system", "generate DESIGN.md", "capture the look of a website", "create a design spec from URL", or "reverse-engineer a site's visual language". Based on the Google Stitch DESIGN.md format.
As a process B 67/100 · Nearly there — weak spots: when it triggers, inputs and preconditions, progress reporting
How to improve
- 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.

Process rating: all ten parameters 67/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 50Failures and branches. 0 branches, has a failure section
- 60Result and completion. Output format stated, no completion criterion
- 100Tools and files. No external tools needed
- 100Steps. 12 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 823 tokens
- 100Running it twice. No mutating operations
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.
