BF UI/UX
The design language that makes AI better at frontend design. 7 domain-specific references (typography, color, spatial, motion, interaction, responsive, UX writing), 20 steering commands (/audit, /critique, /polish, /distill, /animate, etc.), and curated anti-patterns. Use when building or reviewing any UI — fights AI's bias toward generic templates.
As a process F 40/100 · Will not run — References files that are not bundled: reference/typography.md, reference/color-and-contrast.md, reference/spatial-design.md
How to improve
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- The text references files that are not there: add them or drop the references.
- 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 40/100
- 0Tools and files. 7 referenced file(s) missing: reference/typography.md, reference/color-and-contrast.md, reference/spatial-design.md
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 30Running it twice. 60 mutating operations with no state check
- 40Consistency. Frontmatter name (UI/UX) differs from the folder (impeccable-uxui)
- 40Execution cost. Instruction body is 10984 tokens: crowds the task out of the window
- 50When it triggers. No condition that starts the skill
- 100Steps. 66 steps
- 100Failures and branches. 12 branches, has a failure section
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 57 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (3 tags): a typed call is more reliable
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.
