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 high-quality, codebase-specific design-rules skill: it teaches exactly the non-obvious things (grep-first reuse, spinnerTarget mechanics, cache eviction on rejection, .finally over .then, the 8-level priority order) with concrete file paths, function names, commands, and real failure stories. Structure and actionability are strong; the only improvements are tightening the longest prose paragraphs and making the checklist's verify step an explicit fix-and-recheck loop.
Suggestions
Convert the three long reuse examples and the four skeleton-mechanism paragraphs into tight bullet points (or move them to a references/ file linked from a short overview), trimming roughly a third of the prose without losing any file paths or function names.
Make checklist step 5 an explicit feedback loop: 'Verify in a real browser; if the element renders wrong or escapes its tab, re-check it against the existing pattern it was meant to match and re-verify before calling it done.'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every paragraph carries project-specific, non-obvious knowledge (file paths, function names, exact failure modes) that Claude cannot already know, e.g. 'resolveSpinnerTarget() (front/js/common.js) looks for .spinnerTarget among the active tab-pane's direct children only'. Not 5: several long single-paragraph examples (the third reuse example, the lifecycle and readiness-gating paragraphs) could be tightened into shorter statements or bullets without losing information. Not 3: there is no padding and no explanation of concepts Claude already knows — everything is this codebase's own rules. | 4 / 5 |
Actionability | The guidance is fully executable: copy-paste grep commands ('grep -rn "pagination\|paginate_button" front/', 'grep -rn \.DataTable( front/'), exact file paths (front/js/common.js, front/js/app-init.js, front/deviceDetailsPresence.php, front/css/dark-patch.css), exact markup patterns ('<span class="badge ${cssClass}">${iconHtml} ${label}</span>'), and concrete code-level prescriptions ('.finally(hideSkeleton)' not '.then(hideSkeleton)', 'currentMac !== lastMac', the #panX position:relative anchor rule). Specific examples cover the common cases (pager, status badge, data table, loading skeleton). | 5 / 5 |
Workflow Clarity | The 'Practical checklist before building a new UI element' gives a clear numbered 5-step sequence (grep for existing implementation -> reuse -> check the PRD -> design new with the priority order -> 'Verify visually in a real browser/devcontainer before calling it done') with an explicit verification checkpoint. Not 5: no explicit feedback loop after verification fails (no 'if it renders wrong, do X and re-check' step), though the failure-story examples partially compensate by describing what goes wrong and how it was caught. | 4 / 5 |
Progressive Disclosure | A single-file skill with well-organized, clearly headed sections (reuse-before-inventing, skeleton mechanisms, fetch-once, omission rule, priority order, checklist) and no bundle files exist, so all referenced paths (front/js/..., front/css/...) are subject-matter pointers, not navigation references. Not 5: the body is ~60 dense lines / ~11.7KB with three long worked examples and four multi-paragraph mechanism subsections that could be split into one-level-deep reference files so the SKILL.md body stays a leaner overview. | 4 / 5 |
