Conciseness

The body is lean and every sentence carries non-obvious, version-specific facts (tracking semantics of table.atoms reads vs. snapshots, whole-store read re-run cost, and the anti-drift note "There is no selected `table.state`, `subscribeTable`, or `SubscribeSource`"). It never explains concepts Claude already knows, matching anchor 5's 'every token earns its place'.

Actionability

The guidance is fully executable: a concrete prerequisite command (`intent load @tanstack/table-core#table-state`), a complete copy-paste-ready Svelte 5 example covering the common controlled-pagination case including both `Updater` forms, named APIs (`useSelector` from `@tanstack/svelte-store`), and exact .d.ts file paths to inspect. This matches anchor 5's 'copy-paste ready code covering the common cases'.

Workflow Clarity

For this single-purpose reference skill the flow is unambiguous: an explicit first step ('Before starting, run intent load...'), read patterns, then control patterns in order, with a clear escalation condition for the reference file and an API-discovery step to verify installed contracts. There are no destructive or batch operations, so no validation checkpoint is required; the simple-skill exception applies.

Progressive Disclosure

The SKILL.md is a compact overview with core patterns inline, and the one bundle file (references/reactivity.md) exists, is clearly signaled with explicit conditions for when to read it ('For createTableState, external atoms, broad invalidation, or a page index overwritten by automatic reset'), and is one level deep with no nested references. This matches anchor 5's 'clear overview with well-signaled one-level-deep references'.

Specificity

"Read and control Table v9 state in svelte" names the domain with two concrete verbs, and the Use-for clause lists several specific capability areas ("tracked reads, subscriptions, controlled slices"). It falls just short of anchor 5 because coverage has minor gaps (e.g., initialization and reset handling are not named), but it clearly exceeds anchor 3, which expects only 1-2 concrete actions.

Completeness

It answers both parts: the what ("Read and control Table v9 state in svelte") and an explicit when ("Use for tracked reads, subscriptions, controlled slices, and framework-specific reactive boundaries"). Not anchor 5 because the when-clause is phrased as capability areas rather than concrete user-utterance trigger phrases (e.g., 'when the user mentions TanStack table state in Svelte').

Trigger Term Quality

Terms like "table state", "svelte", "subscriptions", and "controlled slices" are natural phrasings a user working in this domain would say. It misses anchor 5 because very common user terms like "TanStack", "pagination", and file/package-style variations are absent, but coverage is well above anchor 3's 'some relevant keywords'.

Distinctiveness Conflict Risk

"Table v9 state in svelte" carves out a clear niche with distinct triggers, explicitly scoping to one framework, so it would not fire for sibling framework skills or generic state-management skills. Minor ambiguity from omitting the library name keeps it from being a borderline case, but it cleanly matches anchor 5's 'clear niche with distinct triggers; minimal conflict risk'.
