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 emails. For popup copy, see popups. For editing existing copy, see copy-editing. For the offer underneath the copy (bonuses, guarantees, value framing), see offers.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-organized, mostly lean instruction skill with concrete formulas, examples, and clean progressive disclosure to two genuine reference files. Its main gap is the absence of explicit validation/review checkpoints within the writing workflow itself, though it routes polishing to the copy-editing skill.

Suggestions

Add an explicit post-draft verification step (e.g., run the draft through the Quick Quality Check and fix flagged items before presenting) so the workflow has a built-in validation checkpoint rather than deferring all review to copy-editing.

Tighten the Clarity Over Cleverness paragraph — the '+81% conversions / 38% shorter sales cycle / 28% lower CAC / 175% more referrals' stat block reads as marketing for the principle; one supporting figure or a pointer to copy-frameworks.md would preserve the point with fewer tokens.

Provide one fully worked page example (a complete hero: headline + subheadline + CTA) so the formulas and style rules are demonstrated end-to-end, closing the minor actionability gap.

DimensionReasoningScore

Conciseness

Largely lean and assumes Claude's competence (principle bullets, tables, terse rules) with no padded explanation of what copywriting is; a few sections such as the clarity stats and verbose CTA lists could be tightened slightly, keeping it just below the most austere anchor.

4 / 5

Actionability

Provides concrete, copy-ready guidance — headline formulas ('{Achieve outcome} without {pain point}'), a CTA formula ([Action Verb] + [What They Get]), and ✅/❌ before/after examples — though it relies on principles over fully worked page examples, leaving minor gaps.

4 / 5

Workflow Clarity

The Before Writing → Principles → Style → Structure → Output sequence is clear with a context-gathering checklist and explicit 'check for product-marketing.md first' step, but there are no explicit validation/review checkpoints after drafting beyond the pointer to the copy-editing skill.

4 / 5

Progressive Disclosure

Well-structured overview with clearly signaled one-level-deep references to real bundle files (references/copy-frameworks.md with working #clarity--message-market-fit anchor, references/natural-transitions.md); detailed frameworks are offloaded while the SKILL.md stays navigable.

Description

91%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, explicit description that clearly states what the skill does and when to use it, with rich natural trigger terms and deliberate boundary routing to sibling skills. It is third-person and comprehensive, with only minor distinctiveness overlap to closely related copy skills.

DimensionReasoningScore

Specificity

Names the domain (marketing/website copy) and multiple specific actions — 'write, rewrite, or improve marketing copy' across named page types (homepage, landing, pricing, feature, about, product) — with only minor coverage gaps such as ad/CTA copy being implied rather than enumerated.

4 / 5

Completeness

Explicitly answers both 'what' (write/rewrite/improve marketing copy for listed page types) and 'when' (Use when... / Also use when the user says...) with concrete trigger phrases, plus a 'Use this whenever...' catch-all clause.

5 / 5

Trigger Term Quality

Comprehensive coverage of natural phrases users would actually say ('write copy for', 'headline help', 'CTA copy', 'value proposition', 'tagline', 'hero section copy', 'this copy is weak', 'make this more compelling'), spanning synonyms and variations.

5 / 5

Distinctiveness Conflict Risk

Clear niche (website marketing copy) with explicit routing away from adjacent skills (email→emails, popup→popups, editing→copy-editing, offers→offers); minor overlap risk remains with copy-editing and cro which are addressed only by brief pointers.
