77%Weight 40%Scale 1-3Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is highly actionable and has a well-sequenced workflow with explicit self-check validation, but it is a long monolithic document with real duplication between its positive rules and negative checklist and no progressive disclosure into separate files.
Suggestions
Dedupe the failure-mode checklist against the positive sections: failure modes 11, 14, 15, and 16 restate the Frame/Composition rules — collapse them into brief cross-references (e.g. 'see §Frame') to cut ~30-40 lines.
Split the large CSS design-system block and/or the 16-item failure list into one-level-deep reference files (e.g. references/design-system.md, references/failure-modes.md) and surface them with clearly signaled links so SKILL.md reads as an overview.
Tighten repeated rationales inside rules (e.g. the SVG-text-explanation appears in both §Composition and failure mode 16) to a single statement plus a pointer.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is skill-specific with no generic concept padding, but ~280 lines with notable duplication between the positive sections and the 16-item failure-mode checklist (letterbox, left-sliver, big-number, and SVG-label rules each appear twice), so it could be tightened. | 2 / 3 |
Actionability | Provides copy-paste-ready CSS (:root vars, .slide{position:fixed;inset:0…}, exact clamp() values), an exact output path, exact keyboard nav, and concrete font stacks — fully executable guidance. | 3 / 3 |
Workflow Clarity | The 8-step 'Working method' is clearly sequenced with explicit validation checkpoints (the 'Self-check' invariants and 'Revise against §Failure modes'), providing a clear feedback loop. | 3 / 3 |
Progressive Disclosure | There are no bundle files and everything lives inline in one ~280-line file; it is well-sectioned and navigable, but monolithic — the detailed CSS and failure-mode content could be split into clearly-signaled one-level-deep references rather than fully inline. | 2 / 3 |
