83%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.
An excellent, highly actionable skill body with a clear multi-step workflow, validation feedback loops, and well-structured progressive disclosure to a real reference bundle. The main weakness is repetition of the auto-layout sizing rules across multiple sections, which inflates token cost without adding clarity.
Suggestions
Consolidate the layoutSizing HUG/FILL guidance — currently repeated across Rule 12, 12a, 12b, the pre-flight checklist, and the error-recovery table — into one canonical location and cross-reference it.
Tighten the Efficient APIs section's prose (e.g. the placeholder/screenshot subsections) by trimming explanatory sentences that restate what the code already shows.
Move the full Editor Mode node-type availability/blocked lists into a reference file, keeping only the design-vs-FigJam-vs-Slides URL rule and createPage caveat inline.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is information-dense and mostly assumes Claude's API knowledge, but several rules and tables restate the same pitfall multiple times (the HUG/FILL auto-layout rules appear in rules 12, 12a, 12b, the checklist, and the error-recovery table) and some passages re-explain basic mechanics Claude already knows. | 3 / 5 |
Actionability | It provides copy-paste-ready executable JavaScript for the common cases (page switching, query/set, createAutoLayout, screenshot, inspection scripts) plus concrete error-message-to-fix tables, covering the common cases with specific, runnable examples. | 5 / 5 |
Workflow Clarity | The incremental workflow is explicitly sequenced with validation checkpoints (inspect → skeleton → fill → validate with get_metadata/get_screenshot → fix before moving on) and a destructive/atomic-error feedback loop (STOP, read error, fix, retry) that matches the rubric's best anchor. | 5 / 5 |
Progressive Disclosure | The SKILL.md is a clear overview with well-signaled, one-level-deep references into real files (gotchas.md, common-patterns.md, etc., all present in references/), plus a 'When to load / What it covers' reference-doc table that makes navigation easy. | 5 / 5 |
