Conciseness

The body is dense with project-specific rules and avoids explaining generic concepts Claude already knows, but the ASCII architecture diagram, the 'Key Rules' section that largely restates rules already given in full above, and some duplicated dependency-direction prose could be trimmed.

Actionability

Concrete, near-executable TypeScript and Svelte examples (the defineKeys/createAudioQueries module shape, the .options reactive usage, the fetch/ensure imperative handlers) plus a decision table for adapter choice. Minor gaps: the Svelte example uses an undefined 'recording', and the second imperative example ends in a '// Continue with transcription...' stub.

Workflow Clarity

Adapter selection, module placement, error flow, and reactive-vs-imperative usage are each resolved by explicit rules and a 'When to Use Each' table, and rule 6 guards optimistic writes with an explicit rollback-path condition. It is a pattern-selection skill rather than a multi-step pipeline, so there are no validation checkpoints — appropriate here, but the cache-update rule stops short of showing the invalidation sequence it defers to references.

Progressive Disclosure

The body is a well-organized overview and the References section signals exactly one level of on-demand depth ('If working with X, read references/Y.md') for error pass-through, runtime DI, and advanced cache patterns; all three referenced files exist in the bundle and contain self-contained material with no nested onward references.

Specificity

The description names the domain ('Query boundaries with TanStack Query and Wellcrafted Results') but the 'what' is a single jargon-heavy action phrase; the API names (createQuery, defineQuery, etc.) are trigger terms rather than stated capabilities, so coverage of concrete actions is not comprehensive.

Completeness

Both parts are present: a 'what' ('Query boundaries with TanStack Query and Wellcrafted Results') and a very explicit 'Use when editing...' clause with concrete triggers. Not a 5 because the 'what' is a single terse phrase and does not state what the skill actually does with those boundaries (patterns, placement rules, adapter shapes).

Trigger Term Quality

Strong keyword coverage of the domain's own API surface ('createQuery, createMutation, resultQueryOptions, resultMutationOptions, defineQuery, defineMutation, defineKeys, shared cache identity, mutation lifecycle'), but common variations users would say are missing, e.g. 'query cache', 'cache invalidation', 'optimistic updates', 'query keys'.

Distinctiveness Conflict Risk

The niche is narrow and the factory-name triggers (resultQueryOptions, defineKeys) are highly distinct, but 'createQuery'/'createMutation' and mutation-lifecycle terms overlap with the closely related sibling skills the body itself points to ('svelte', 'services-layer'), so minor overlap risk remains.
