Conciseness

The body assumes Claude's TypeScript competence — no concept tutorials or library comparisons — but restates the two-argument rule three times ('Two arguments max... No exceptions', Key Principles, Universal Signature) and the Benefits section reads as filler. It is not 5 because of this minor redundancy, and not 3 because padding is limited to a few spots rather than whole sections.

Actionability

Concrete TypeScript examples dominate the body (core pattern, multiple dependencies, four-zone shape), plus actionable decision aids (the `this` decision table, adapter stay/collapse signs). It is not 5 because several later examples use ellipsis bodies (`connect() { ... }`, `watch(fn) { /* ... */ }`) making them pattern illustrations rather than copy-paste-ready code, and not 3 because the examples are still concrete and specific, with key details present.

Workflow Clarity

This is a pattern-application skill rather than a multi-step procedure, and the single action (apply the factory pattern) is unambiguous: recognize the signature, spot the four anti-patterns, follow the zone ordering and decision rules. It is not 5 because there is no explicit sequence tying the sections into an ordered application procedure, and not 3 because the anti-pattern catalog and decision rules function as clear checkpoints.

Progressive Disclosure

The 'Load on demand' section cleanly signals two one-level-deep references, both of which exist in references/, each with a description of when to load it. It is not 5 because the ~320-line body inlines substantial specialized material (structural contracts, the collapsed-adapter rule, the four-zone anatomy) that could itself be split into a reference file, and it also leans on five external article paths outside the bundle.

Specificity

The description lists several concrete actions — 'compose clients and services', 'wrapping resources with domain methods', 'refactoring mixed client/service/method options' — with only minor coverage gaps (e.g., structural contract satisfaction covered in the body is absent). It is not 3 because it goes beyond 1-2 actions and every action is domain-specific, and not 5 because coverage is not comprehensive of the skill's full scope.

Completeness

It explicitly answers both what ('Factory function patterns to compose clients and services') and when ('Use when wrapping resources with domain methods or refactoring mixed client/service/method options') with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Phrases like 'factory function', 'compose clients and services', 'wrapping resources with domain methods', and 'refactoring mixed client/service/method options' are terms a TypeScript user would naturally say. It is not 5 because common synonyms such as 'dependency injection', 'service layer', or 'create* function' variants are missing.

Distinctiveness Conflict Risk

'Factory function patterns' is a clear niche with distinct triggers (wrapping resources, refactoring mixed options), unlikely to fire for unrelated skills; voice is appropriately third-person.
