Conciseness

The body is lean and assumes Claude's competence: no padding, no explanation of what a table library is, every line is concrete pattern or a wrong/correct contrast. Tokens are tight and each earns its place.

Actionability

Provides copy-paste ready executable TypeScript for setup, core patterns, and common mistakes with concrete wrong/correct code pairs and named APIs (getVisibleCells, getAllLeafColumns), covering the common cases directly.

Workflow Clarity

This is a simple, single-purpose skill under 50 lines where the action is unambiguous; the Setup → Core Patterns → Common Mistakes → API Discovery flow gives a clear sequence and the wrong/correct pairs act as inline correctness checks, satisfying the simple-skill exception.

Progressive Disclosure

Well-organized into clear sections with content appropriately contained inline (no bundle files exist, and the body is short enough not to need them); the only reference is a one-level-deep pointer to inspect node_modules for API discovery, which is clearly signaled.

Specificity

Names the domain (column visibility) and several concrete actions ('Hide columns', 'rendering visibility-aware header, column, and cell collections'), which lists multiple specific actions but is not fully comprehensive (no mention of toggling, state inspection, or API surface).

Completeness

Clearly states what it does ('Hide columns with columnVisibilityFeature while rendering visibility-aware header, column, and cell collections') and explicitly answers when to load it ('Load when hidden columns remain in the DOM, false-versus-absent state is confused, or enableHiding is misunderstood').

Trigger Term Quality

Includes natural trigger phrases users would say ('hidden columns remain in the DOM', 'false-versus-absent state is confused', 'enableHiding is misunderstood') with good keyword coverage, but misses some common synonyms a user might naturally say (e.g. 'show/hide columns', 'toggle column').

Distinctiveness Conflict Risk

Targets a clear niche (TanStack table-core column visibility feature) with distinctive triggers tied to specific API behaviors, making conflict with other skills minimal.
