77%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.
A well-executed procedural skill: the add-a-theme checklist is fully sequenced with verification and troubleshooting feedback loops, and the variable reference is app-specific knowledge Claude could not infer. The main structural weakness is that the large Color Variable Reference is inlined in SKILL.md rather than split into a references/ file, inflating context cost for every skill load.
Suggestions
Move the Color Variable Reference (background/text/border/accent/status/button/agent variable tables) into references/variables.md and keep a short summary table in SKILL.md, since no bundle files currently exist to absorb the ~130-line reference.
Include a minimal example .theme-<name> class snippet (a few variables with hex values) so the core artifact is templated rather than solely deferred to copying theme-dark.scss.
Trim the duplicated opacity guidance: the 'Color opacity suffix convention' table repeats percentages already stated in the status-color and bg-tier sections; a single table would suffice.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense reference material with no padding and no explanation of concepts Claude already knows; every section adds app-specific knowledge. Minor over-explanation remains ('Practical way to ensure completeness' prose, and the opacity suffix table partially duplicating the status-variant semantics), so it fits the 4 anchor rather than 5's every-token-earns-its-place bar. | 4 / 5 |
Actionability | Exact file paths, an `@use` SCSS snippet, an i18n JSON snippet, and a complete variable inventory make the guidance mostly executable. Minor gaps keep it below 5: no example SCSS theme class is shown (the skill defers to copying theme-dark.scss), and verification steps are manual UI actions rather than commands. | 4 / 5 |
Workflow Clarity | A clearly sequenced 7-step checklist with an explicit verification step ('Confirm the new theme appears in the dropdown... whole UI updates'), a quality-check step (WCAG AA contrast, key surfaces, hover states), and a troubleshooting section mapping failure to fix ('Theme not showing up: missing @use import... missing entry in THEMES'). This matches the 5 anchor's explicit validation plus error-recovery feedback loops; the destructive/batch cap does not apply. Not 4 because feedback loops are explicit, not merely present. | 5 / 5 |
Progressive Disclosure | No bundle files exist and the ~130-line Color Variable Reference is inlined in a 265-line SKILL.md instead of being split into a one-level-deep references/ file. Structure itself is good, but content that clearly belongs in a separate reference file is inline, matching the 3 anchor; it is not 4 because there are no well-signaled references at all. | 3 / 5 |
