The description names the domain (marketing page optimization/CRO) and lists page types (homepage, landing pages, pricing pages, feature pages, blog posts), but it doesn't list specific concrete actions the skill performs (e.g., 'analyzes headlines, rewrites CTAs, restructures page layout'). The 'what it does' is more about the domain than specific actions.

Clearly answers both 'what' (optimize/improve conversions on marketing pages) and 'when' (extensive explicit trigger phrases and scenarios, including the URL-sharing edge case). The 'Use when' guidance is thorough and explicit.

Excellent coverage of natural trigger terms users would actually say: 'CRO,' 'conversion rate optimization,' 'this page isn't converting,' 'my landing page sucks,' 'nobody's converting,' 'low conversion rate,' 'bounce rate is too high,' 'people leave without signing up,' and more. These are highly natural, colloquial phrases that real users would use.

Excellent distinctiveness — explicitly delineates boundaries by referencing related but separate skills (signup-flow-cro, onboarding-cro, form-cro, popup-cro) and clarifying when to use each. This cross-referencing significantly reduces conflict risk.

The content is reasonably well-organized but includes substantial material that an LLM already knows about CRO (e.g., explaining what social proof is, listing common objection types, defining what 'friction points' are). Many sections read like a CRO textbook rather than novel, project-specific instructions. Could be tightened significantly.

Provides structured checklists and specific headline patterns/CTA copy examples, which is helpful. However, it lacks executable code, concrete tool commands, or specific implementation steps. It's more of a consulting framework than step-by-step executable guidance — there's no code to run, no specific tools to use, and recommendations are general CRO best practices rather than precise instructions.

There's a clear sequence (initial assessment → analysis framework in priority order → output format), and the output structure (Quick Wins / High-Impact / Test Ideas / Copy Alternatives) is well-defined. However, there are no validation checkpoints or feedback loops — no step to verify recommendations against data, no checkpoint to confirm the analysis is complete before outputting, and no iterative refinement process.

Content is well-structured with clear sections, references related skills appropriately (signup-flow-cro, form-cro, etc.), and points to a reference file for experiment ideas. The main skill serves as an overview with one-level-deep references that are clearly signaled.
