custom-features

Author a TanStack Table v9 feature plugin across every FeatureMap and API installation surface: state, options, column definitions, table, column, row, cell, header, row-model functions/caches, defaults, prototypes, and table/row/column instance data lifecycles. Load for initTableInstanceData, resetTableInstanceData, constructTableAPIs, or reusable behavior not covered by built-ins, meta, or option composition.

Quality

Content

82%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 dense, actionable guide built around a fully executable reference example, with clear lifecycle sequencing and well-structured sections. Slight gains are available from trimming prose/guardrails redundancy and adding an explicit verification step.

DimensionReasoningScore

Conciseness

Lean and assumes Claude's competence with no concept-over-explanation; minor redundancy where the lifecycle prose is restated as Guardrails rules, which could be tightened.

4 / 5

Actionability

A complete, copy-paste-ready TypeScript example demonstrates every FeatureMap declaration-merge and API installation path, covering the common cases end to end.

5 / 5

Workflow Clarity

Lifecycle ordering is clearly stated ('runs once after options, state atoms, and the store exist... before any constructTableAPIs hook runs') and sections are well sequenced, though no explicit verification checkpoint is given.

4 / 5

Progressive Disclosure

Well-organized sections with one-level-deep external pointers (API Discovery → node_modules type paths); no bundle files exist and the inline content is appropriately focused, with only minor organization gaps.

Description

85%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 precise, well-scoped description that answers both what it does and when to load it, with comprehensive surface coverage and minimal conflict risk. Its only weakness is trigger terms that lean on technical API names rather than natural-language phrases.

DimensionReasoningScore

Specificity

Lists multiple concrete installation surfaces — 'state, options, column definitions, table, column, row, cell, header, row-model functions/caches, defaults, prototypes, and table/row/column instance data lifecycles' — giving comprehensive coverage of what the feature touches.

5 / 5

Completeness

Clear 'what' ('Author a TanStack Table v9 feature plugin across every FeatureMap and API installation surface') and explicit 'when' trigger guidance ('Load for initTableInstanceData, resetTableInstanceData, constructTableAPIs, or reusable behavior not covered by built-ins, meta, or option composition').

5 / 5

Trigger Term Quality

Trigger terms are heavily technical jargon ('initTableInstanceData', 'resetTableInstanceData', 'constructTableAPIs', 'option composition'); relevant to the niche but missing plain-language synonyms or variations a user would naturally say.

3 / 5

Distinctiveness Conflict Risk

A sharply specific niche — TanStack Table v9 feature plugin authoring tied to named API hooks — with distinct triggers and minimal overlap with other skills.
