71%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 lean, well-structured review skill with concrete attribute-level criteria and a clean single-reference progressive-disclosure design. The main weaknesses are triple restatement of the same requirements across Quick Reference/Check/Fix and a missing inline verification pointer in the review workflow. Note also that the referenced rule.md contains broken code blocks (missing component function signatures, an empty 'Usage' block) that undermine the skill's promised 'code examples'.
Suggestions
Collapse the Quick Reference/Check/Fix duplication into one statement of the required markup pattern, keeping the body at a single source of truth for the criteria.
Add a verification step to the Code Review workflow that points to the checklist in references/rule.md (e.g. 'Confirm findings against the rendered DOM using the Verification checklist in references/rule.md').
Fix the code examples in references/rule.md — the React/Next.js snippets are missing their component function declarations and the 'Usage' section is an empty code block — since the body promises complete, framework-specific code examples there.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is short but noticeably redundant: the same requirements (nav + aria-label, ordered list, aria-current='page') are restated three times across 'Quick Reference' ('Use nav element with aria-label'), 'Check' ('Verify breadcrumbs use nav element with aria-label, ordered list markup, and aria-current'), and 'Fix' ('Implement breadcrumbs using semantic nav, ol/li structure, and proper ARIA attributes including aria-current'). The opening motivation sentence ('Proper breadcrumb markup helps screen reader users understand site hierarchy...') is also explanation Claude does not need. It is not a 2 because nothing explains basic concepts and the body stays lean overall. | 3 / 5 |
Actionability | The 'Quick Reference' gives concrete, executable attribute-level instructions ('Use nav element with aria-label=Breadcrumb', 'Use ordered list (ol) for semantic structure', 'Mark current page with aria-current=page'), and the 'Code Review' section directs concrete output ('Flag exact elements, attributes, and routes where the rendered HTML violates the rule'). It is not a 5 because no valid/invalid markup example appears inline and 'Keep any structured data aligned with the visible breadcrumb trail' lacks the specifics (order, labels, when to omit) needed to act without opening the reference. | 4 / 5 |
Workflow Clarity | For a simple single-purpose review skill, the Check → Fix → Explain → Code Review structure is unambiguous and the review targets are named ('Review templates, server-rendered HTML, and shared components that output markup'). It is not a 5 because the body contains no verification checkpoint for confirming findings against the final rendered DOM (that checklist lives only in references/rule.md and is not pointed to from the review steps). | 4 / 5 |
Progressive Disclosure | The body is a concise overview with well-organized sections and a single, clearly signaled, one-level-deep pointer: 'For full implementation details, code examples, and framework-specific guidance, see references/rule.md' — and references/rule.md exists in the bundle and is the only bundled reference file. This matches the anchor 'Clear overview with well-signaled one-level-deep references; content appropriately split'. | 5 / 5 |
