Conciseness

The body is lean throughout: no padding, no explanation of concepts Claude already knows (nothing explains what AIDA is or why copy matters), and every section earns its place — e.g., the Overview adds a real constraint ("do not let the framework become visible scaffolding") rather than filler. This matches anchor 5 ('lean and efficient; assumes Claude's competence; every token earns its place'); anchor 4 would require identifiable over-explanation, of which there is none.

Actionability

Concrete, specific guidance throughout: an exact context-gathering checklist ("Product, audience, pain point, desired action, channel, constraints, and tone"), a framework-to-situation mapping ("AIDA for attention-to-action sequences"), component-level output patterns ("headline, subhead, primary CTA, proof bullets, objection handling"), and three fully-specified example prompts. Per the rubric's code-vs-instruction note, absence of code is not penalized for an instruction-only skill, but a worked example output (e.g., one sample variant set) would be needed to reach anchor 5's 'specific examples cover the common cases' fully; anchor 4's 'concrete guidance with minor gaps' is the best fit.

Workflow Clarity

A clear six-step numbered sequence with an explicit quality checkpoint (step 6: "Flag missing proof, risky claims, or places where product context is too thin") and decision guidance in step 2 and step 4. The skill is non-destructive and non-batch, so the validation cap does not apply. It sits at anchor 4 ('clear sequence with most checkpoints present; minor validation gaps') rather than 5 because there is no explicit feedback loop (e.g., review the draft against the gathered context and revise) after drafting.

Progressive Disclosure

The skill is under 50 lines, single-purpose, and ships no bundle files — verified against the directory listing, with no inline references to nonexistent files — so per the rubric guideline it can score 5 on well-organized sections alone. The four sections (Overview, Workflow, Output Patterns, Example Prompts) are clear, appropriately sized, and everything is rightly inline at this scale; nothing that belongs in a separate file is inlined.

Specificity

The description names two concrete actions ("Write marketing copy for pages, campaigns, product launches, ads, and email sequences" and "refreshing existing marketing content") across a comprehensive list of deliverable types, but the action vocabulary is limited compared to the level-5 anchor's multiple distinct operations; minor gaps in coverage (e.g., no mention of producing test variants or headline/subject-line work as a capability). This fits anchor 4 ('several specific actions; minor gaps') rather than 5, and is clearly above anchor 3's '1-2 concrete actions' given the breadth of named deliverables.

Completeness

Both halves are explicit and concrete: the 'what' ("Write marketing copy for pages, campaigns, product launches, ads, and email sequences") is followed by a full 'Use when the user asks for...' clause listing concrete trigger phrases. This directly matches the level-5 anchor ('clearly and explicitly answers both what AND when with concrete trigger phrases'); anchor 4 would require the 'when' to be less explicit than it is.

Trigger Term Quality

Strong natural terms users would actually say: "landing page copy, launch copy, ad variations, direct-response frameworks, AIDA, PAS, BAB" plus the explicit `/copywriting` invocation. A few common synonyms are missing (e.g., 'sales copy', 'web copy', 'hero copy', 'email subject lines', 'taglines'), which matches anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive synonym coverage, and is well above anchor 3's 'missing common variations'.

Distinctiveness Conflict Risk

A clear copywriting niche with distinct trigger phrases (framework names like AIDA/PAS/BAB, landing page copy, ad variations) that no adjacent skill (general writing, editing, documentation) would naturally claim — matching anchor 5's 'clear niche with distinct triggers; minimal conflict risk'. Anchor 4's 'minor overlap risk with closely related skills' is not a better fit since the triggers are unmistakably marketing-specific.
