row-selection

Maintain rowSelection ID state with stable getRowId, single, multi, subrow, and Shift-range rules, selected row models, handler anchors, and manual-pagination semantics. Load when implementing getToggleSelectedHandler, enableRowRangeSelection, selectChildren, deselectParents, or selected IDs that outlive loaded Row objects.

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.

The body is dense, executable, and free of padding, with strong Wrong/Correct guidance for the subtle row-selection pitfalls. It is a reference-style skill rather than a sequenced workflow, so it lacks explicit validation checkpoints and external progressive-disclosure files.

Dimension	Reasoning	Score
Conciseness	Lean and token-efficient: every section conveys non-obvious row-selection behavior (anchors, selectChildren, deselectParents, select-all rules) without explaining concepts Claude already knows, and the Wrong/Correct pairs are tight.	5 / 5
Actionability	Provides copy-paste-ready TypeScript for setup, each handler factory, and Wrong/Correct fixes in Common Mistakes, covering the single/multi/subrow/Shift-range cases concretely.	5 / 5
Workflow Clarity	Organization is clear (Setup → Core Patterns → Common Mistakes → API Discovery) and the destructive operations (row deletion, deselect-all) carry corrective guidance, but there are no explicit validation checkpoints because the skill is a pattern reference rather than a sequenced workflow.	4 / 5
Progressive Disclosure	Well-structured with clear sections and a one-level API Discovery pointer to the table-core feature directory; no bundle files exist to offload the ~160-line body, so it is appropriately inline with minor organization gaps.	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.

The description is specific, complete, and clearly distinct, explicitly pairing the 'what' with a 'Load when...' trigger clause. Its only weakness is that the triggers are API-symbol-heavy and omit a few natural-language synonyms a user might say.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete capabilities—'stable getRowId, single, multi, subrow, and Shift-range rules, selected row models, handler anchors, and manual-pagination semantics'—giving comprehensive coverage of the skill's behavior surface rather than vague abstraction.	5 / 5
Completeness	Explicitly answers both what ('Maintain rowSelection ID state...') and when ('Load when implementing getToggleSelectedHandler... or selected IDs that outlive loaded Row objects') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Strong coverage of the API symbols a developer would mention ('getToggleSelectedHandler, enableRowRangeSelection, selectChildren, deselectParents'), but the triggers lean on API identifiers rather than natural-language synonyms like 'checkbox' or 'select rows', leaving a few common phrasings out.	4 / 5
Distinctiveness Conflict Risk	Targets a narrow TanStack Table row-selection niche with distinct API triggers, making overlap with unrelated skills minimal.	5 / 5
