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.
The body is an excellent, executable skill: concrete commands, a copy-paste module template, a six-step workflow with explicit review gates and a fix-and-re-render feedback loop, and dense conventions that assume Claude's competence without padding. The one real defect is progressive disclosure: style-tokens.md and review-checklist.md are linked from the Files table and workflow but are absent from the bundle, leaving the skill's color semantics and review criteria unavailable.
Suggestions
Add the missing style-tokens.md and review-checklist.md to the bundle (or fix their paths) — both are linked from the Files table and from workflow steps 1 and 5, and neither exists in the skill directory.
Since the color semantics are load-bearing (step 1 and the Color convention both defer to 'What the colors mean' in style-tokens.md), either inline a minimal color-legend table in SKILL.md or verify the reference resolves, so the workflow does not depend on an unavailable file.
Add a fallback for the missing review-checklist.md content by inlining the key review criteria (equal margins within 4px, shared edges, text centered, vertical alignment) directly into step 5, which currently points only at the absent file.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and dense with project-specific knowledge only (e.g. 'text drawn with dominant-baseline="central" has its visual top about 0.35 × size above its y'; 'Published files are a mix of 1x and 2x; that is history, not a target'). It assumes competence — no explanations of SVG, Chrome, or rendering basics — and no sentence is padding, matching the 5 anchor. | 5 / 5 |
Actionability | Fully executable guidance: exact commands ('grep -rhoE srcLight="[^"]+" docs | sort -u', a concrete curl blob URL, 'CHROME=/path/to/chrome ./render.sh', 'node gen.mjs <name>', 'python3 scripts/measure.py light/<name>.png') and a complete, commented diagram-module template. The sketched draw() body is justified flexibility since each diagram differs, so this is 5 rather than 4. | 5 / 5 |
Workflow Clarity | Six clearly sequenced steps with explicit validation (step 5: 'Look at both PNGs at full size, against review-checklist.md and against the references'; 'Run python3 scripts/measure.py light/<name>.png for the margins'), a feedback loop ('Fix in constants and re-render'), and a hard gate ('Do not hand off a PNG you have not looked at') plus a final name-agreement check — matching the 5 anchor's checkpoints and error-recovery loop. | 5 / 5 |
Progressive Disclosure | The structure is exemplary — a task-to-file table, one-level-deep references, workflow steps linking to the file they need — but scored against the actual bundle, two of the six referenced files ('style-tokens.md' and 'review-checklist.md') do not exist anywhere, and style-tokens.md carries the color semantics ('What the colors mean') that step 1 and the Color convention depend on. A dangling, load-bearing reference is more than the 'minor organization gaps' of the 4 anchor, so this falls to 3. | 3 / 5 |
