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.

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.

The body is a well-structured, highly actionable copywriting guide with excellent progressive disclosure into two real, one-level-deep reference files. Its main cost is token efficiency: several sections restate standard copywriting knowledge Claude already has and duplicate points made elsewhere in the skill or in the references.

Suggestions

Cut or compress sections that restate general copywriting knowledge Claude already has — e.g. 'Use Rhetorical Questions', 'Use Analogies When Helpful', 'Pepper in Humor' — down to a one-line checklist, or move them into references/copy-frameworks.md.

Remove duplication: merge 'Specificity Over Vagueness' (principles) with 'Specific over vague' (style rule) into a single rule, and drop the inline headline-formula list since references/copy-frameworks.md already contains the full formula library (keep one example inline at most).

Make the workflow explicit: replace the implicit section-order flow with a short numbered sequence (read product-marketing context -> gather missing context -> draft per page type -> run the Quick Quality Check -> hand off to copy-editing), so the checkpoints are ordered rather than implied.

DimensionReasoningScore

Conciseness

While each line is terse, the body restates general copywriting knowledge Claude already has (benefits over features, active voice, avoid buzzwords, use rhetorical questions and analogies) and duplicates itself — 'Specificity Over Vagueness' reappears as style rule 'Specific over vague', and four headline formulas are shown inline despite the full library living in references/copy-frameworks.md. Mostly efficient but could be meaningfully tightened, matching anchor 3; not 2 because there is no padded explanatory prose.

3 / 5

Actionability

Highly actionable for an instruction-only skill: concrete headline formulas ('{Achieve outcome} without {pain point}'), weak-vs-strong CTA lists, a real before/after Slack example, a section table with specific counts (3-5 benefits, 3-4 steps), page-type guidance, and a complete output spec (sections, annotations, A/B alternatives with rationale, meta content). Specific examples cover the common cases.

5 / 5

Workflow Clarity

A clear sequence is discernible (check product-marketing context -> gather four context areas -> apply principles -> draft -> quick quality check -> copy-editing handoff), and the Quick Quality Check plus the copy-editing handoff act as checkpoints. Not 5 because the workflow is implied by section order rather than explicitly sequenced with steps; not 3 because checkpoints are present, just implicit.

4 / 5

Progressive Disclosure

The SKILL.md body is a well-organized overview with two clearly-signaled, one-level-deep references ('For comprehensive headline formulas: See references/copy-frameworks.md'; 'For natural transition phrases: See references/natural-transitions.md'), both of which exist and contain exactly what the links promise. Content is appropriately split — sample formulas inline, the full library and transitions in references — making navigation easy.

Description

96%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.

The description is exemplary: it explicitly states what the skill does and when to use it, enumerates an extensive list of natural trigger phrases, and carves out boundaries against sibling skills. The only weakness is residual overlap between rewrite/improve triggers and the copy-editing skill.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('write, rewrite, or improve marketing copy') with comprehensive page-type coverage (homepage, landing, pricing, feature, about, product) and concrete deliverable triggers (headline, CTA copy, tagline, subheadline). Coverage is comprehensive for the web-page copy domain, matching the top anchor rather than the 'minor gaps' of 4.

5 / 5

Completeness

Explicitly answers both what ('write, rewrite, or improve marketing copy for any page') and when ('When the user wants to...', 'Also use when the user says...') with concrete trigger phrases. This clearly matches the top anchor.

5 / 5

Trigger Term Quality

Fourteen quoted natural phrases users would actually say ('write copy for', 'this copy is weak', 'make this more compelling', 'help me describe my product', 'above the fold'). This is comprehensive natural-term coverage including synonyms; only a handful of variants like 'web copy' or 'sales page' are missing.

5 / 5

Distinctiveness Conflict Risk

Clear niche (persuasive web-page copy) with explicit redirects to sibling skills ('For email copy, see emails. For popup copy, see popups. For editing existing copy, see copy-editing'). However, triggers like 'improve this copy' and 'rewrite this page' still overlap the copy-editing boundary, so minor overlap risk with a closely related skill remains — matching anchor 4 rather than 5.
