81%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.
This is a high-quality, deeply actionable skill body with an exceptionally clear workflow (checkpoints, verification checklist, critique rubric) and well-designed progressive disclosure into a verified reference bundle. The main costs are token efficiency: some standard-knowledge sections and repeated rules could be consolidated, and the long always-loaded body could shed more detail to its references. Weighted score 4.25 of 5.
Suggestions
Consolidate the placeholder/no-fabricated-data rules, which currently appear in the cliché table, Placeholder Philosophy, Content Principles, and the Pre-delivery Checklist, into one canonical section and have the checklist reference it by name.
Trim or relocate standard-knowledge sections ("Aim to Stun", "Appropriate Scale", and generic CSS practices like clamp() and prefers-color-scheme) into a reference file, keeping only the skill-specific constraints (no scrollIntoView, no `const styles`, namespacing rules) inline.
Move the full six-row school-library table into references/design-directions.md (which already serves as the school taxonomy), keeping 2–3 sample rows inline in the Design Direction Advisor section to shorten the always-loaded body.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The bulk is expert, non-obvious guidance (asset protocol, calibration dials, iframe/Babel hard rules), but sections like "Aim to Stun", the "Appropriate Scale" table, and generic CSS practices (clamp(), prefers-reduced-motion) restate knowledge Claude already has, and the placeholder/no-fabricated-data rules are repeated across the cliché table, Placeholder Philosophy, Content Principles, and the checklist. Mostly efficient with some unnecessary explanation and tightening opportunities matches anchor 3; not 2 because padding is localized rather than pervasive. | 3 / 5 |
Actionability | Guidance is fully executable for an instruction-only skill: concrete templates (Design Read YAML block, Design Decisions markdown block), exact URLs (Popmotion pinned CDN, Chart.js, D3 v7), quantified thresholds (title/body ≥ 2.5×, ≤ 4 colors, ≤ 2 font families, 1920×1080 canvas), and specific code fixes (`Object.assign(window, { Terminal, Line })`, `element.scrollTop = ...`). Matches the anchor for fully executable, copy-paste-ready guidance covering common cases. | 5 / 5 |
Workflow Clarity | Steps 0–7 are clearly sequenced with three explicit 🛑 checkpoints (with "actually wait" reinforcement), a Step 6 verification phase plus a pre-delivery checklist, a Step 7 critique rubric with scoring, and a repair feedback loop in the browser-acceptance path ("report evidence and repair failures before delivery"). Matches the anchor for clear sequence with explicit validation steps and checklists. | 5 / 5 |
Progressive Disclosure | Structure is strong: a References Routing table maps each task type to one of 8 reference files plus 26 recipe files (all verified to exist), references are one level deep, and the body repeatedly instructs loading only the single needed file. It falls short of anchor 5 because the always-loaded 492-line body still inlines substantial content (the full school-library table, the complete 8-row cliché table) that could partially live in the already-existing design-directions.md and failure-patterns.md references. | 4 / 5 |
