Conciseness

Information-dense and free of generic concept explanations, assuming framework competence; a few prose sentences (e.g., the store.subscribe clarification) could be tightened further but every line is substantive.

Actionability

Provides complete, import-bearing executable examples covering the four ownership patterns (initialState, createAtom, @tracked + onPaginationChange, baseAtoms.set) plus concrete Wrong/Correct pairs, covering the common cases copy-paste ready.

Workflow Clarity

The "Choose One Owner Per Slice" numbered options and explicit read-precedence rule give a clear decision procedure, and Common Mistakes acts as a verification checklist, but there is no explicit validate-then-proceed feedback loop (none is required since the skill is non-destructive).

Progressive Disclosure

Well-organized into clearly headed sections with a one-level-deep "API Discovery" pointer to external .d.ts files; no bundle files exist, and the single-file structure is appropriate, though no multi-file disclosure structure is used.

Specificity

Lists five concrete verbs ("Read, track, initialize, control, and reset") paired with six specific mechanisms ("baseAtoms, atoms, store, Ember createAtom, or @tracked state plus on*Change"), giving comprehensive coverage of the capability surface.

Completeness

The first sentence answers "what" concretely and the "Load for ownership precedence, updater callbacks, stale template state, options-thunk reactivity, or incorrect table.Subscribe/store.subscribe usage" clause provides explicit concrete trigger phrases for "when".

Trigger Term Quality

Strong keyword coverage of API names a developer would naturally say ("TanStack Ember Table", "atoms", "@tracked", "store.subscribe", "table.Subscribe"), but no synonyms or file-extension variants, so a few natural terms are missing.

Distinctiveness Conflict Risk

Scoped tightly to "TanStack Ember Table v9 state" via Glimmer/Ember-specific APIs, creating a clear niche with minimal risk of triggering for unrelated skills.
