Conciseness

The body assumes Claude's competence — it never explains what Svelte stores are — and stays lean with terse steps, decision criteria, and rules. Minor trimming is possible (e.g., boilerplate reset/setter methods in both templates), so it fits anchor 4 rather than anchor 5's every-token-earns-its-place.

Actionability

Two complete, executable TypeScript templates ("Option A: writable/readable store", "Option B: Rune-based class"), exact file placement paths (src/lib/modules/[feature]/stores/[name]-store.ts), and a concrete validation command (npx svelte-check --tsconfig ./tsconfig.json) make the guidance copy-paste ready and cover the common cases — anchor 5.

Workflow Clarity

Six clearly sequenced steps (read architecture doc → determine type → choose placement → create → apply rules → validate) with an explicit validation checkpoint. It falls short of anchor 5 because there is no feedback loop for error recovery (e.g., "if svelte-check fails, fix and re-run"); this is a single-file, non-destructive operation, so the batch/destructive cap does not apply.

Progressive Disclosure

Steps, options, and rules are clearly sectioned, and architecture details are delegated one level deep to docs/ARCHITECTURE.md section 4.4. At ~87 lines with two full templates inlined it is longer than the sub-50-line simple-skill case, so the templates could arguably live in references — matching anchor 4 (good structure, minor organization gaps) rather than anchor 5.

Specificity

"creates Svelte store with server state integration" names the domain and one concrete action, but does not list several specific actions. It matches anchor 3 (domain + 1-2 concrete actions, not comprehensive) rather than anchor 4, which requires several listed actions.

Completeness

Both parts are present: "creates Svelte store with server state integration" (what) and "Use when adding state management to a module" (when). It falls short of anchor 5 because there is only a single trigger phrase and "server state integration" is vague; it exceeds anchor 3 because the when-clause is explicit rather than implied.

Trigger Term Quality

Relevant natural phrases like "state management" and "Svelte store" are present, but common variations users would say are missing (e.g., "create a store", "shared state", "runes", "$state"). This matches anchor 3 — some relevant keywords, missing common variations — rather than anchor 4's good coverage.

Distinctiveness Conflict Risk

"state management" is a broad term that could overlap with other state-management skills, though "Svelte store" narrows the niche. This matches anchor 3 (somewhat specific but could overlap with similar skills) rather than anchor 4, since the trigger phrasing is not tightly scoped to this skill's exact scope.
