Conciseness

The body is lean with no explanations of concepts Claude already knows, but the opening paragraph ("This skill provides guidelines for writing user-facing copy in WooCommerce, including UI text, labels, buttons, messages, and documentation") merely repeats the frontmatter description, and the Key Principle "Always use sentence case for UI text, not title case" duplicates Instruction 1 — minor redundancy that could be trimmed.

Actionability

The only substantive rule delegates to "See [sentence-case.md](sentence-case.md) for rules on using sentence case", and that file does not exist in the bundle (no references/, scripts/, or assets/ directories are present). The remaining principles — "Keep copy concise and action-oriented", "Use clear, simple language", "Be consistent with existing WooCommerce copy patterns" — are high-level hints with no examples, matching the 'minimal concrete guidance, missing specific steps' anchor.

Workflow Clarity

As a simple single-purpose skill, the instruction "Follow these guidelines when writing any user-facing text" is coherent and unambiguous in intent. However, the substance that would govern execution — the sentence-case rules — is a pointer to a missing file, and the fallback principles are generic, leaving guidance present but incomplete with no concrete checkpoints.

Progressive Disclosure

Scored against the actual bundle structure: the body's single reference is clearly signaled and one level deep, but sentence-case.md is absent from the skill directory entirely, so the delegated content does not exist and navigation dead-ends. A working, clearly-signaled one-level reference would merit a 3 or higher; a broken sole reference leaves the skill without its substance.

Specificity

Names the domain ("UI text and copy in WooCommerce") and artifact types ("labels, buttons, messages"), but the only action framing is "Guidelines for" — no concrete action verbs like write, review, or audit, so it matches the 'domain plus limited actions' anchor rather than a list of several specific actions.

Completeness

Both parts are present: an explicit "Use when writing user-facing text, labels, buttons, messages, or documentation in WooCommerce projects" trigger and a clear-enough what ("Guidelines for UI text and copy in WooCommerce"). Not a 5 because the 'what' restates the domain rather than enumerating concrete capabilities.

Trigger Term Quality

Good natural keyword coverage — "user-facing text", "UI text", "labels", "buttons", "messages", "documentation", "WooCommerce" — phrases a user would plausibly say, but common variations like "microcopy", "error messages", "placeholder text", or "tone" are missing, placing it just below comprehensive.

Distinctiveness Conflict Risk

"WooCommerce" pins a clear niche with distinct triggers and minimal conflict risk, but "documentation" and generic "writing text" create minor overlap with general writing and brand-style skills, keeping it below the clear-niche anchor.
