86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The content is a dense, token-efficient design spec with exact CSS values, viewport dimensions, input-handling branches, and explicit prohibitions (no external mockup images, no lorem ipsum, no srcdoc nesting). It is a strong single-file skill whose only notable gap is the absence of a complete HTML starting example and a final output check.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a lean imperative spec with exact values ('rotateY(-12deg) rotateX(4deg) translateZ(40px)', '#a8a8ad', '375×812') and explains nothing Claude already knows — every token earns its place. Not below 5 because no section is padded and no concept is over-explained. | 5 / 5 |
Actionability | Guidance is mostly executable: concrete CSS transforms, gradient definitions, viewport dimensions, and explicit branching rules for input types ('text/data → render mock app UI', 'HTML → embed as-is with scaling'). Not 5 because there is no complete copy-paste HTML skeleton — the snippets are real CSS values but fragmentary; not 3 because the fragments given are directly usable, not pseudocode. | 4 / 5 |
Workflow Clarity | A single-purpose generation task with well-separated sections (intent → hard composition → screen content source → optional elements → design details) and explicit decision points for input types, so the action is unambiguous. Not 5 because there is no final output verification step (e.g. check the embedded content fits the screen viewport); not 3 because the sequence and constraints are clearly laid out with no destructive or batch operation requiring validation. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines with no external references needed, and the body is organized into clear labeled sections; per the rubric's guideline this earns a 5. No bundle files exist to reference, and none are needed at this size. | 5 / 5 |
