Conciseness

The body is lean and assumes competence: no explanation of what Alpine or TanStack Table is, no filler. Every line carries non-obvious information ("A captured value outside a binding does not become a continuing subscription, and there is no table.Subscribe component"). Version numbers live in frontmatter, not the body, and the single code example earns its place.

Actionability

The controlled-getter setup is complete, copy-paste-ready TypeScript with imports, reactive owner, getter, and updater callback, plus a concrete read instruction ("Read table.atoms.pagination.get().pageIndex directly in an Alpine binding"). The boundaries section gives concrete failure modes with exact code shapes ("state: { pagination: local.pagination } captures the old object") and points to real .d.ts files for the rest.

Workflow Clarity

For a single-purpose reference skill, the sequence is unambiguous: load the shared intent module first, understand what counts as a tracked read, apply the controlled-getter setup, then follow the boundary rules. Not a destructive or batch operation, so no validation checkpoints are required, and the "Load ... first" directive makes the entry point explicit.

Progressive Disclosure

The SKILL.md is a well-organized overview that keeps deep material out: advanced reactive-boundary detail is one level deep in references/reactivity.md (verified to exist and to contain the advanced content the body defers), clearly signaled by "For advanced reactive boundaries, shared atoms, or detailed subscription examples, read [reactivity](references/reactivity.md)", with a labeled cross-link to the getting-started skill for a different concern.

Specificity

"Read and control Table v9 state in alpine" names the domain and two concrete actions, and the trigger clause enumerates specific capabilities ("tracked reads, subscriptions, controlled slices, and framework-specific reactive boundaries"). Not 5 because "read and control" is broad and the enumerated items are capability areas rather than fully concrete operations like "fill forms" or "merge documents".

Completeness

Both parts are present: "Read and control Table v9 state in alpine" (what) and "Use for tracked reads, subscriptions, controlled slices, and framework-specific reactive boundaries" (explicit "Use for" trigger guidance, so it clears the 3-cap). Not 5 because the when-clause lists abstract capability categories rather than concrete user situations (e.g., "Use when wiring pagination state to Alpine.reactive or debugging stale bindings").

Trigger Term Quality

Includes natural terms a user would say: "Table v9 state", "alpine", "tracked reads", "subscriptions", "reactive boundaries". Not 5 because it omits the library name users most naturally mention ("TanStack Table", "@tanstack/alpine-table") and common synonyms like "reactivity" or "pagination state"; not 3 because keyword coverage beyond the domain name is genuinely good.

Distinctiveness Conflict Risk

"Table v9 state in alpine" carves out a clear, narrow niche: the Alpine adapter for TanStack Table v9 state management. Even against closely related sibling skills (table-state for other frameworks), "in alpine" and "framework-specific reactive boundaries" explicitly disambiguate; minimal conflict risk.
