72%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 concise, well-organized instruction skill that assumes Claude's competence and gives concrete design directives. Its main weakness is workflow clarity, since it presents principles rather than a sequenced process with validation checkpoints.
Suggestions
Add a short decision checklist or sequenced flow for the 'when to create a base component' judgment (e.g., identify the part -> check for accessibility behavior -> reuse existing base or create one -> surface the decision) to give the workflow clearer sequence and checkpoints.
Tighten the intro and 'Relationship to hooks' paragraphs by dropping comparative framing ('similar in spirit to Base UI or Radix Primitives', 'Both are first-class') unless it changes a decision.
Consider a one-line 'Validation' note for the CSS reset guidance (e.g., confirm the :where() wrapped selector yields the intended 0,1,0 specificity) so the most error-prone instruction has an explicit checkpoint.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence (no explaining what React, A11y, or ARIA is), but a few sentences carry non-essential framing ('similar in spirit to Base UI or Radix Primitives', 'Both are first-class') that could be trimmed, placing it above 3 yet short of the every-token-earns-its-place 5. | 4 / 5 |
Actionability | Concrete directives like 'ship flat named exports', 'ship a minimal CSS reset using :where() selectors', and 'build on a shared primitive such as ButtonBase' give actionable guidance with only minor gaps; per the instruction-skill note the absence of copy-paste code is not penalized because the guidance is specific. | 4 / 5 |
Workflow Clarity | This is design guidance rather than a sequenced operational workflow, so steps and validation checkpoints are largely implicit; the one soft checkpoint ('surface the decision explicitly') prevents a lower score, but there is no clear sequence to reach a 4 or 5. | 3 / 5 |
Progressive Disclosure | At ~46 lines with no bundle files needed, the body is organized into clear, well-signaled sections (When to use, What a base component covers, Deciding which parts, CSS reset, Relationship to hooks) with inline one-level references to sibling skills and ADRs, matching the simple-skill exception for progressive disclosure. | 5 / 5 |
