82%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-structured, highly actionable conventions reference: concrete code for every common case, VS Code-specific knowledge Claude could not infer, and clear deferral to the canonical token file. The main weakness is redundancy in the text-overflow section and slight size-related overlap between sections 3 and 10.
Suggestions
Consolidate §9's three separate ellipsis code blocks into one canonical example plus the flex min-width: 0 gotcha, and prune the anti-pattern list of items that merely restate the 'three properties required' rule.
Move the full §10 token tables and snap maps into a references/ file (e.g., size-tokens.md), keeping only the decision pointers and the stylelint requirement in SKILL.md.
Add a short end-of-workflow verification step (e.g., 'run stylelint/hygiene after adding or changing CSS variables') so the feedback loop present only in §10 applies to the whole skill.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly lean — dense tables, copy-paste code, and project-specific conventions Claude would not know (monaco- prefixes, min-width: 0 gotcha, token snap maps) rather than general CSS tutorials. Minor trimming is possible: §9 shows the same three-property ellipsis combo in three separate code blocks and the anti-pattern list restates rules already given, and §3/§10 overlap slightly on sizes. | 4 / 5 |
Actionability | Guidance is fully executable: copy-paste-ready SplitView/IView instantiation, Grid.addView, DomScrollableElement with the required scanDomNode() call, the exact three-property ellipsis CSS, and the setupDelayedHover() snippet, plus concrete decision rules (snap maps, tie-rounding, glyph-compact caveats) for the common cases. | 5 / 5 |
Workflow Clarity | Mostly reference-style decision rules with a clearly sequenced checklist ("When building a responsive component: 1–4") and one genuine feedback loop: §10 states that stylelint/hygiene fails if a --vscode-* var is missing from vscode-known-variables.json and how to fix it (add to both baseSizes.ts and the JSON). Not 5 because most sections lack explicit validation checkpoints; not 3 because no destructive/batch operations require them and what sequences exist are unambiguous. | 4 / 5 |
Progressive Disclosure | Ten well-numbered sections with a closing Key Files table make navigation easy, and §10 appropriately defers bulk tables to the canonical auto-injected .github/instructions/design-tokens.instructions.md, keeping only decision logic inline. Not 5 because everything lives in one 330-line file with no references/ split for the detailed token tables, which is acceptable but leaves minor organization headroom. | 4 / 5 |
