copywriting
When the user wants to write, rewrite, or improve marketing copy for any page — including homepage, landing pages, pricing pages, feature pages, about pages, or product pages. Also use when the user says "write copy for," "improve this copy," "rewrite this page," "marketing copy," "headline help," "CTA copy," "value proposition," "tagline," "subheadline," "hero section copy," "above the fold," "this copy is weak," "make this more compelling," or "help me describe my product." Use this whenever someone is working on website text that needs to persuade or convert. For email copy, see email-sequence. For popup copy, see popup-cro. For editing existing copy, see copy-editing.

Discovery
89%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong skill description with excellent trigger term coverage and completeness. The explicit cross-references to related skills effectively reduce conflict risk. The main weakness is that the 'what' portion could be more specific about concrete actions or techniques beyond generic 'write, rewrite, or improve.'
Suggestions
Add specific concrete actions like 'craft headlines, write CTAs, develop value propositions, structure hero sections' to improve specificity beyond generic 'write, rewrite, or improve'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description names the domain (marketing copy) and mentions page types (homepage, landing pages, pricing pages, etc.), but lacks specific concrete actions beyond generic 'write, rewrite, or improve.' It doesn't specify what techniques or outputs are produced. | 2 / 3 |
Completeness | Clearly answers both what (write/rewrite/improve marketing copy for various page types) and when (explicit 'Use when' with extensive trigger phrases). Also includes helpful cross-references to related skills for disambiguation. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms users would say: 'write copy for,' 'improve this copy,' 'headline help,' 'CTA copy,' 'value proposition,' 'tagline,' 'hero section copy,' 'above the fold,' 'make this more compelling.' These are highly natural phrases. | 3 / 3 |
Distinctiveness Conflict Risk | Explicitly distinguishes itself from related skills (email-sequence, popup-cro, copy-editing) with clear boundaries. The focus on website marketing copy for persuasion/conversion creates a distinct niche with specific triggers. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured, actionable copywriting skill with clear workflows and good progressive disclosure. The main weakness is some verbosity in explaining concepts Claude already understands (benefits vs features, active vs passive voice). The concrete examples, formulas, and structured output format make this highly actionable.
Suggestions
Remove or condense explanations of basic copywriting concepts Claude already knows (e.g., 'Features: What it does. Benefits: What that means for the customer' and active/passive voice definitions)
Tighten the 'Writing Style Rules' section by removing obvious guidance like 'Sentences trying to do too much?' and focusing only on project-specific preferences
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is generally efficient but includes some unnecessary explanation that Claude would already know (e.g., defining benefits vs features, explaining what active vs passive voice is). Some sections like 'Writing Style Rules' could be tightened. | 2 / 3 |
Actionability | Provides concrete, actionable guidance throughout: specific CTA formulas, example transformations (weak → strong), page structure tables, and clear output format requirements. The examples are specific and immediately usable. | 3 / 3 |
Workflow Clarity | Clear workflow: check for existing context → gather missing info → apply principles → structure by page type → output in specified format. The 'Before Writing' section establishes a clear sequence, and the output format section provides explicit deliverables. | 3 / 3 |
Progressive Disclosure | Well-structured with clear overview sections and appropriate references to external files (copy-frameworks.md, natural-transitions.md). Related skills are clearly signaled at the end. Content is appropriately split between this file and reference materials. | 3 / 3 |
Total | 11 / 12 Passed |
