93%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.
An exemplary instruction-only skill body: dense, specific, and directive throughout, with a rare focus on non-obvious environmental constraints (opaque origins, dashboard-stamped data-theme) rather than generic design tutorial content. The only notable gap is the absence of an explicit verification step for the two-theme rendering requirement it mandates.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body assumes Claude's competence (never explains HTML, CSS, or fonts) and spends every line on non-obvious constraints and directives, e.g. "The viewer frames have an opaque origin, so `localStorage`, `sessionStorage`, and cookies throw on access" — nothing reads as padding. | 5 / 5 |
Actionability | For an instruction-only skill the guidance is fully concrete: a copy-paste-ready three-layer theming CSS block plus named, specific techniques ("`prefers-color-scheme`", "`text-wrap: balance`", "`font-variant-numeric: tabular-nums`", "`overflow-x: auto`", "`color-scheme`"). | 5 / 5 |
Workflow Clarity | A clear sequence is prescribed ("Sketch a compact plan before writing HTML, then follow it", then derive all decisions from it) with an explicit review-and-revise loop for editorial requests, but there is no general verification checkpoint (e.g., confirming both themes render) to reach the anchor-5 validation bar. | 4 / 5 |
Progressive Disclosure | A single-file skill with six flat, well-labeled sections and no content that belongs in a separate file — nothing is reference-nested and nothing is buried, matching the well-organized no-external-references case. | 5 / 5 |
