82%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 tight, highly actionable pattern-and-pitfalls skill: executable code, concrete Wrong/Correct contrasts, and API details correctly deferred to installed type definitions. It is held back from maximum scores by verbatim snippet repetition and the absence of an explicit step sequence or validation checkpoints.
Suggestions
Collapse the repeated reactive-count getter and scrollElement snippets into a single canonical Setup block and reference it from Core Patterns/Common Mistakes to cut token redundancy.
Add a short explicit sequence (build the Table model in table-state -> virtualize the final row/column model -> apply renderer geometry) as a numbered checklist near the top.
Consider moving the four HIGH Common Mistakes into a references file (e.g., MISTAKES.md) with a one-line index here, to shorten the inline body and strengthen progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean, assumes Claude's competence (no explainer on what virtualization or Solid is), and uses terse one-line rationales after each mistake, but the reactive-count getter and scrollElement pattern reappear verbatim across Setup, Core Patterns, and Common Mistakes, a minor redundancy that keeps it just short of fully lean. | 4 / 5 |
Actionability | Executable TSX throughout — Setup gives a complete createVirtualizer block, and each Common Mistake pairs a copy-paste-ready Wrong snippet with a Correct one — while API Discovery defers exhaustive method coverage to the installed .d.ts, covering the common row/column/infinite/measurement cases concretely. | 5 / 5 |
Workflow Clarity | The ordering principle is stated up front ('Virtualize the final Table model in the renderer; Virtual is not a Table feature') and Common Mistakes flag the main failure modes, but there is no explicit numbered sequence or validation checkpoint; since the operations are non-destructive the destructive cap does not apply, so this sits at clear-but-implicit sequencing rather than full stepwise clarity. | 4 / 5 |
Progressive Disclosure | No bundle files exist, so scoring is against body structure: clear sections (Setup, Core Patterns, Common Mistakes, API Discovery) with the deep API surface deferred one level to installed type defs and example repos, but there is no explicit reference-file navigation and the Common Mistakes catalog is fairly long inline, leaving minor organization gaps. | 4 / 5 |
