Conciseness

Most sections are tight and skill-specific (diagnosis table, three-question gate, AI-tell rules with rewrites, claims protocol), but a few sections restate copywriting knowledge Claude already has — "Use Analogies When Helpful", "Pepper in Humor (When Appropriate)", and the "Voice and Tone" formality/boldness checklists — which is minor over-explanation fitting anchor 4 rather than the every-token-earns-its-place level of anchor 5.

Actionability

For an instruction-only skill the guidance is fully executable: the A/B/C situation table with per-situation jobs, the three-question gate with explicit pass thresholds, banned patterns with named rewrites, CTA formula "[Action Verb] + [What They Get] + [Qualifier if needed]", ❌/✅ Slack example, and a [NEED: ...] flagging convention with a defined output format — specific examples cover the common cases.

Workflow Clarity

The multi-step process is clearly sequenced (read product-marketing context file → gather context → state diagnosis "in one line with the evidence" → decompose and lock units → three-question gate → leave-it-alone test → deliver) with explicit validation checkpoints ("Three passes, keep it. Two, sharpen the weak one. One or none, rewrite it") and feedback loops (revert changes you can't justify; flag missing proof rather than inventing it).

Progressive Disclosure

The body is a well-organized overview with three real, clearly signaled, one-level-deep references (ai-tells.md, copy-frameworks.md, natural-transitions.md); anchor links resolve to actual sections ("The Self-Check", "Build a Writer", "Clarity & Message-Market Fit"), and bulk detail (full blacklist, headline formula catalog, templates) is appropriately split into the bundle with concise summaries retained inline.

Specificity

Names concrete actions ("write, rewrite, or improve marketing copy") plus specific behaviors ("Drafts never use AI tells", "a declined claim names the evidence that would unlock it", "Diagnoses the input first") in third person, but the distinct operation set is a single family — produce/improve page copy — leaving minor coverage gaps versus the multi-action comprehensiveness of anchor 5.

Completeness

Explicitly answers both questions: what ("write, rewrite, or improve marketing copy for any page", with behavioral constraints) and when ("When the user wants to... Also use when the user says..." followed by fourteen concrete trigger phrases), which matches the anchor-5 example structure exactly.

Trigger Term Quality

Comprehensive natural trigger phrases users would actually say — "write copy for", "headline help", "CTA copy", "this sounds like AI", "AI slop", "make it sound human", "help me describe my product" — plus an enumeration of page types, matching the anchor-5 level of synonym coverage (file extensions are not applicable to this domain).

Distinctiveness Conflict Risk

Clear niche (page marketing copy) with explicit disambiguation redirects — "For email copy, see emails. For popup copy, see popups. For editing existing copy, see copy-editing. For the offer underneath the copy... see offers" — which actively minimizes conflict with adjacent skills rather than just being distinct.
