Conciseness

Every sentence carries non-obvious, Ember/Table-v9-specific knowledge — owner binding via 'pass `this` as the owner', reading tracked data inside the options thunk, receiver requirements for prototype methods, and 'Register `columnVisibilityFeature` before switching to `row.getVisibleCells()`'. There is no padding, no explanation of concepts Claude already knows, and nothing to trim; the version requirement ('Ember 5.8 or newer requires Embroider or ember-auto-import v2') is a current setup constraint rather than stale time-sensitive guidance.

Actionability

The Setup section is a complete, copy-paste-ready `.gts` component covering the common case (typed columns, tracked data, row model, cell rendering with FlexRenderCell), and the API discovery section gives exact declaration file paths to inspect. This matches the fully-executable anchor with concrete examples covering the common cases, not the 'minor gaps' of level 4.

Workflow Clarity

The flow is unambiguous and correctly ordered: load the prerequisite core intent 'first', check framework requirements, run Setup, apply construction/rendering rules, then route advanced needs. No destructive or batch operations are involved, so no validation checkpoints are required, and the simple-skill exception applies: the single action (set up and render a basic table) is unambiguous, with guards like the columnVisibilityFeature registration note preventing common errors.

Progressive Disclosure

The body is a lean overview with well-signaled, purpose-scoped, one-level-deep pointers: 'When tables share features, defaults, or reusable UI, read [create-table-hook](references/create-table-hook.md)' (verified to exist), 'read [table-state](../table-state/SKILL.md)' for reactive ownership, and an API discovery section pointing to node_modules declarations instead of inlining API reference. Content is appropriately split and navigation is easy, matching the level 5 anchor.

Specificity

The description lists several concrete, library-specific actions — 'Create and render Table v9 with the ember adapter', 'Route reusable createTableHook defaults, and framework setup', 'use table-state for reactive ownership' — matching the anchor for several specific actions with minor gaps in coverage (e.g., column/feature configuration is not mentioned). It is not level 5 because coverage is not comprehensive, and not level 3 because it goes well beyond 1-2 generic actions.

Completeness

The 'what' is clearly stated (create/render Table v9 with the ember adapter, route reusable hooks and setup), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is above level 2 because the 'what' is concrete, and below level 4 because the 'when' is entirely absent rather than merely imprecise.

Trigger Term Quality

Natural terms a user would say are present: 'Table v9', 'ember adapter', 'createTableHook', 'table-state', 'framework setup'. A few common variations are missing ('@tanstack/ember-table', 'tanstack', 'data table/grid'), so it fits the 'good keyword coverage; a few natural terms missing' anchor rather than the comprehensive level 5.

Distinctiveness Conflict Risk

'Table v9 with the ember adapter' carves out a clear niche, and sibling-skill concerns (table-state for reactive ownership, createTableHook for shared defaults) are explicitly routed away, leaving minimal conflict risk. Re-reading the level 4 anchor ('minor overlap risk with closely related skills') fits less well since the framework and version qualifiers make this skill clearly distinguishable.
