88%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 thorough, highly actionable skill body with strong workflow sequencing, validation checkpoints, and well-organized one-level-deep references. The main weakness is length and some repetition across rules, tables, and the checklist.
Suggestions
Consolidate the repeated layoutSizing error messages (Rules 12/12b, the error-recovery table, and the checklist) into a single canonical entry to reduce duplication.
Move the full query-selector syntax reference and editor-mode node-type lists into a dedicated reference file, keeping only a compact example inline.
Tighten the pre-flight checklist by cross-referencing rules instead of restating each one verbatim.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense with hard-won, non-obvious API knowledge and no explaining of concepts Claude already knows, but the body runs ~430 lines with some repetition (long error-message strings restated across rules, the error-recovery table, and the checklist) that could be trimmed. | 4 / 5 |
Actionability | Abundant copy-paste-ready, executable JavaScript (createAutoLayout, query selectors, set batching, inspection scripts, screenshot calls) covering the common cases with specific syntax. | 5 / 5 |
Workflow Clarity | Section 6 gives a clearly sequenced incremental workflow with explicit validation checkpoints (inspect, build skeleton, fill, return IDs, validate with get_metadata/get_screenshot, fix before proceeding) plus a pre-flight checklist and error-recovery feedback loops, satisfying the destructive/batch validation requirement. | 5 / 5 |
Progressive Disclosure | Good structure with a reference-docs table pointing one level deep to well-signaled files in references/, though some inline sections (the full query-selector syntax table, editor-mode node lists) are detailed enough they could live in a reference. | 4 / 5 |
