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.
Highly actionable, project-specific content: every section carries non-obvious, hard-won guidance backed by exact file paths, real markup, copy-paste greps, and a sequenced checklist with a visual-verification checkpoint. The main room for improvement is trimming the twice-stated morals in the example narratives and adding an explicit what-to-do-on-failure loop after visual verification.
Suggestions
Tighten the three 'real example' paragraphs in 'Core principle: reuse before inventing' - each currently states its lesson twice (narrative plus restated moral); one crisp sentence of takeaway per example would cut roughly a third of the section without losing the failure modes.
In the practical checklist, extend step 5 with an explicit recovery action when visual verification fails (e.g. 'if it renders wrong, diff against the reference pattern's markup and re-implement using it') to close the error-recovery loop.
Consider moving the detailed spinnerTarget/skeleton mechanics (positioning, lifecycle, show/hide symmetry, readiness gating) into a reference file linked from a short summary in SKILL.md, keeping the main file an overview of the reuse-first principle, priority order, and checklist.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and entirely project-specific (spinnerTarget direct-child lookup, .finally vs .then, per-mac cache eviction, getStatusBadgeParts markup) with no generic-concept padding, and includes ready-to-run greps like "grep -rn \"pagination\\|paginate_button\" front/". However, the three 'real example' paragraphs each restate their moral twice (e.g. "Approximating a reference pattern 'from memory'... is the same mistake as not searching at all - read the real template...") and the spinnerTarget section runs long, so it sits at 'efficient; minor instances of over-explanation that could be trimmed' rather than 'every token earns its place'. | 4 / 5 |
Actionability | Guidance is fully executable: copy-paste grep commands ("grep -rn '.pagination(' front/"), exact file paths (front/js/common.js, front/deviceDetailsPresence.php, front/js/plugin_column_render.js), the real markup pattern ("<span class=\"badge ${cssClass}\">${iconHtml} ${label}</span>"), and precise behavioral directives (".finally(hideSkeleton) ... not .then(hideSkeleton)", "currentMac !== lastMac, not just a one-time boolean flag", wrap in callAfterAppInitialized()). Specific examples cover the common cases (pager, status badge, plugin table, skeleton), matching the copy-paste-ready score-5 anchor for an instruction-only skill. | 5 / 5 |
Workflow Clarity | The closing 'Practical checklist before building a new UI element' is a clearly sequenced 5-step list with an explicit validation checkpoint ("Verify visually in a real browser/devcontainer before calling it done") and conditional decision points at steps 3-4 ("If it doesn't, that's a signal to look harder"). It falls short of score 5 only because there is no explicit error-recovery loop after visual verification fails (what to do when the render is broken), which is a minor validation gap. | 4 / 5 |
Progressive Disclosure | A single self-contained file with no bundle directories and clearly headed sections (Core principle, Loading skeletons, Fetch once, Don't omit, Priority order, Checklist), so navigation is easy and references are one level deep by construction. It slightly exceeds the under-50-lines simple-skill exception (~54 lines), and the long real-example narratives and the detailed spinnerTarget mechanics could arguably live in a reference file, placing it at 'good structure; most content is appropriately placed; minor organization gaps'. | 4 / 5 |
