100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a tight, well-structured skill that assumes competence, gives concrete executable guidance, sequences the work with a finishing validation checklist, and is appropriately organized for a sub-50-line single-purpose skill with no external references needed.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence — it gives the viewport meta verbatim, lists relative units and thresholds, and never explains what HTML/CSS/JS or a viewport is; the only repetition (the one-line summary guardrail) is intentional reinforcement, not padding, so it meets the 'lean and efficient; every token earns its place' anchor. | 3 / 3 |
Actionability | Guidance is concrete and executable: an exact viewport meta tag, specific relative units, a 44px tap-target floor, a ~400-line split threshold, file naming (index.html), and named tool calls (GenerateImage, Read, Edit, Write); per the rubric's instruction-only note, the absence of a full HTML skeleton is not penalized when guidance is this actionable. | 3 / 3 |
Workflow Clarity | A clear numbered Workflow (1–5) is followed by a 'Review heuristics before finishing' checklist that acts as an explicit validation checkpoint (tap targets, offline render, alt tags, AA contrast), matching the 'clear sequence with explicit validation steps; checklists' anchor for this simple skill. | 3 / 3 |
Progressive Disclosure | At under 50 lines with no bundle files present (references/scripts/assets directories do not exist) and no need for external references, the well-organized sections (Constraints, Workflow, Review heuristics, Working with the user) satisfy the simple-skills note that progressive disclosure can score 3 on organization alone. | 3 / 3 |
