Quality

Content

90%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A compact, highly actionable reference that assumes Claude's competence and leads with executable code and wrong/correct patterns. The main gap is the absence of an explicit sequenced workflow with validation, which is acceptable for this single-purpose skill but keeps workflow clarity and progressive disclosure at 4.

Suggestions

Add a short numbered sequence (import features → wire mousedown/touchstart handlers → apply CSS-variable sizing) so the workflow is explicit rather than implied across sections.

If the Common Mistakes catalog grows, move detailed entries into a references/ file and keep SKILL.md as a concise overview with one-level-deep links to raise progressive disclosure.

Include a brief verification step (e.g., confirm resize state updates and widths render) so the workflow has an explicit checkpoint.

Dimension	Reasoning	Score
Conciseness	Lean and code-driven with no padding of concepts Claude already knows; prose is limited to non-obvious domain specifics like the touchstart/mouse distinction, so every token earns its place per the 5 anchor.	5 / 5
Actionability	Copy-paste ready executable code in Setup and Core Patterns plus concrete wrong/correct pairs for each Common Mistake, fully covering the common cases per the 5 anchor.	5 / 5
Workflow Clarity	Organization implies a clear Setup → wire handlers → optimize sequence and the skill is single-purpose (not destructive/batch), but there is no explicit numbered sequence or validation checkpoint, fitting the 4 anchor with minor gaps rather than the explicit-checkpoint 5.	4 / 5
Progressive Disclosure	Well-organized into Setup, Core Patterns, Common Mistakes, and API Discovery with no nested references and a self-contained body, but at ~74 lines with the full mistakes catalog inline it has minor organization gaps versus the cleanly-split 5 anchor; no bundle files exist to evaluate against.	4 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that covers both capabilities and explicit load triggers with minimal fluff. It is slightly heavy on API jargon over natural user phrasing, which keeps trigger-term quality at 4 rather than 5.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Wire columnResizingFeature, header.getResizeHandler, resize mode and direction, pointer or touch events, and performant CSS-variable updates' — with comprehensive coverage of the feature's surface, matching the score-5 anchor rather than the minor-gaps anchor at 4.	5 / 5
Completeness	Explicitly states both what ('Wire columnResizingFeature... performant CSS-variable updates') and when ('Load when resize state changes but widths do not, or large tables resize slowly') with concrete trigger phrases, matching the 5 anchor; not the 4 anchor where 'when' is only loosely tied.	5 / 5
Trigger Term Quality	Good keyword coverage mixing API names with natural phrases ('resize state changes but widths do not', 'large tables resize slowly'), but it leans technical and omits common synonyms/extensions users might say, fitting the 4 anchor better than the comprehensive 5.	4 / 5
Distinctiveness Conflict Risk	Targets a clear niche (TanStack table column resizing) with distinctive, library-specific triggers and minimal overlap risk with other skills, matching the 5 anchor.	5 / 5
