92%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 tight, high-signal instruction skill: reproduction-first procedure, a concrete cause→fix table for the common front-end bug classes, anti-pattern guidance (don't hide errors), and explicit exit criteria that serve as validation checkpoints. Its only weakness is two fix entries that describe what to inspect without saying what to change.
Suggestions
Make the image fix entry concrete: instead of "fix the container or loading strategy", state the specific remedy (e.g., remove transform/containment from the lazy-image's ancestor, or switch to native loading="lazy" with width/height attributes).
Concretize the refactor entry: replace "check loaded fonts and initial overlay state" with the actual check (e.g., confirm the @font-face family name still matches post-refactor and that modal overlays are mounted hidden with aria-hidden until open).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line carries project-specific knowledge Claude cannot infer (the 360/390/768/1280 viewport list, the ≥400px fixed-width threshold, the "Chromium results don't count for Safari bugs" rule, the BLOCKED convention). No concept explanations, no padding — lean and efficient throughout. | 5 / 5 |
Actionability | Mostly executable guidance: "add max-width:100%, flex-wrap, overflow-wrap:anywhere", "Measure against clientWidth, not innerWidth", "native listeners with { passive: false }" are copy-paste-ready fixes for the common cases. Two entries stay high-level — "fix the container or loading strategy" and "check loaded fonts and initial overlay state" name what to inspect but not what to change — which are the minor gaps that keep it below fully-executable 5. | 4 / 5 |
Workflow Clarity | Clear sequence with explicit validation: reproduce on the reported engine/viewport (step 1), fix at cause, then "Re-run the tester's full UI sweep for the route on every viewport, and check neighbors that share the component", capped by an Exit criteria checklist including error recovery for missing Safari ("marked BLOCKED if no real Safari is available"). This matches the anchor-5 pattern of explicit validation steps plus a feedback/checklist. | 5 / 5 |
Progressive Disclosure | A sub-50-line, single-purpose skill with no bundle files (references/, scripts/, assets/ do not exist) and no content that belongs in separate files; sections (Procedure, Exit criteria, counterpart pointer) are well organized. Per the simple-skill guideline, this earns a 5 with just well-organized sections, and the qa-browser-ui counterpart reference is clearly signaled and not nested. | 5 / 5 |
