Conciseness

Every line is an actionable directive with specific API names, generic-parameter counts, and file paths; no background concepts are explained and no section is padded. Even the warning "Renaming `createSvelteTable` alone does not complete the migration" preempts a known shortcut and earns its tokens.

Actionability

Concrete, executable guidance is present: the command `intent load @tanstack/table-core#migrate-v8-to-v9`, inspectable paths (`node_modules/@tanstack/svelte-table/dist/index.d.ts`), and precise directives like "Update `SvelteTable` to two generic parameters and `AppSvelteTable` to five". Not a 5 because the actual replacement code lives in the referenced file, so the body alone is not copy-paste executable.

Workflow Clarity

A clear sequence is present: prerequisite check (Svelte 5), core checklist load, adapter audit, conditional detail-loading ("When the audit finds old Svelte construction... read adapter migration details before editing"), then an explicit verification section (type-check, exercise feature flows, verify state writes). Not a 5 because there is no explicit error-recovery feedback loop, e.g. what to do when the type-check fails.

Progressive Disclosure

The body is a concise overview with a single well-signaled, one-level-deep reference (references/adapter-migration.md, verified to exist and contain the Svelte-specific mappings), gated by an explicit condition, plus purposeful cross-links to sibling skills for a render scaffold and state handling. Content is appropriately split and easy to navigate.

Specificity

"Migrate svelte Table v8 to v9. Audit framework construction, rendering, state, and app hooks" names the domain and several concrete action areas, with explicit scoping of shared changes to the core skill. It falls short of a 5 because the actions are essentially migrate/audit applied to areas rather than a comprehensive list of distinct concrete actions, but exceeds a 3 since more than 1-2 specific actions are stated.

Completeness

The "what" is clear (migrate Svelte Table v8 to v9, auditing construction, rendering, state, and app hooks), but there is no "Use when..." clause or equivalent explicit trigger guidance, so "when" is only weakly implied by the migration framing. Per the judging guideline, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Natural trigger terms users would say are present: "migrate", "svelte", "Table", "v8 to v9". It is not a 5 because common variations like "TanStack", "upgrade", or "@tanstack/svelte-table" are missing from the description (the package name appears only in frontmatter metadata), and not a 3 because the core natural phrases are all covered.

Distinctiveness Conflict Risk

"svelte Table v8 to v9" defines a clear niche with minimal conflict risk, and the phrase "with shared API changes in the core migration skill" explicitly partitions scope away from the closely related core migration skill, keeping the boundary distinct despite the sibling skill existing.
