78%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 body is exceptionally actionable — concrete formulas, shipped parameter values, and executable code make it immediately usable — and largely concise for the density it carries. Its main structural weakness is that it is one monolithic document: no progressive disclosure at all, with several self-contained topic areas (typography, design foundations, audio-haptics) that belong in separate reference files.
Suggestions
Split self-contained topics into one-level-deep reference files (e.g., references/typography.md, references/design-principles.md, references/materials.md) and keep SKILL.md as an overview with well-signaled links.
Trim §16 (eight design principles) and §17 (process) to their tactical rules — the philosophical framing Claude can supply itself — and deduplicate the interruptibility guidance that recurs across §3, §5, and §6.
Add a short 'when building X, apply §A then §B' usage path so the numbered sections function as a build sequence rather than only a topic catalog.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly dense and non-obvious content (exact damping/response values, the exponential projection formula, rubber-band function, Motion API mapping), but §16's eight multi-sentence design principles and §17's process philosophy are wordy conceptual prose, and interruptibility guidance recurs across §3/§5/§6. Not 5 (there is trimmable philosophical padding); better than 3 (no basic-concept filler). | 4 / 5 |
Actionability | Fully executable guidance throughout: copy-paste CSS/JS snippets, a concrete damping/response value table, exact formulas (project(), rubberband(), relative-velocity normalization), and a need→technique→concrete-value Quick Reference table covering the common cases. | 5 / 5 |
Workflow Clarity | A reference/knowledge skill, not a stepwise process — no destructive or batch operations, so the validation cap does not apply. Topics are numbered in a coherent progression (response → direct manipulation → interruptibility → springs → …) and the Quick Reference provides a lookup path, but there is no explicit build-then-verify sequence; this sits between the organized-reference (4) and steps-listed-without-checkpoints (3) anchors. | 4 / 5 |
Progressive Disclosure | No bundle files exist (no references/, scripts/, or assets/), so the entire ~280-line corpus is inline in SKILL.md. In-file structure is good (numbered sections, quick-reference table), but separable reference material — typography (§15), the eight design principles (§16), audio-haptics (§13) — is inlined rather than split into reference files, matching the 'some structure; content that should be separate is inline' anchor rather than the good-split anchor at 4. | 3 / 5 |
