copy-editing
When the user wants to edit, review, or improve existing marketing copy. Also use when the user mentions 'edit this copy,' 'review my copy,' 'copy feedback,' 'proofread,' 'polish this,' 'make this better,' 'copy sweep,' 'tighten this up,' 'this reads awkwardly,' 'clean up this text,' 'too wordy,' or 'sharpen the messaging.' Use this when the user already has copy and wants it improved rather than rewritten from scratch. For writing new copy, see copywriting.

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 clear disambiguation from related skills. The main weakness is that the 'what' portion could be more specific about the concrete editing actions performed (e.g., grammar fixes, tone adjustments, concision improvements) rather than just listing general verbs like 'edit, review, improve.'
Suggestions
Add specific concrete actions to the beginning, e.g., 'Tightens prose, fixes grammar, improves clarity, strengthens calls-to-action, and adjusts tone in existing marketing copy.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (marketing copy) and lists general actions (edit, review, improve), but doesn't specify concrete capabilities like 'tighten sentences, fix grammar, improve clarity, strengthen CTAs.' | 2 / 3 |
Completeness | Clearly answers both what (edit, review, improve existing marketing copy) and when (explicit trigger phrases plus clarification about existing copy vs new copy), with helpful disambiguation from the copywriting skill. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural user phrases: 'edit this copy,' 'proofread,' 'polish this,' 'make this better,' 'too wordy,' 'sharpen the messaging' - these are exactly what users would naturally say. | 3 / 3 |
Distinctiveness Conflict Risk | Explicitly distinguishes itself from copywriting skill ('For writing new copy, see copywriting'), focuses on editing existing copy, and includes specific trigger phrases that create a clear niche. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
77%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, highly actionable skill with excellent workflow clarity through the Seven Sweeps Framework. The main weakness is its length—at 300+ lines, much of the detailed content (checklists, word tables, problem/fix examples) could be moved to referenced files for better progressive disclosure. The content is valuable but could be more token-efficient.
Suggestions
Move the detailed checklist section to a separate file (e.g., copy-editing-checklist.md) and reference it from the main skill
Extract the 'Common Copy Problems & Fixes' section to a reference file, keeping only 1-2 examples inline
Trim the philosophy section and 'Key principles' list—Claude understands editing principles; focus on the unique framework
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is comprehensive but includes some unnecessary explanation (e.g., 'Good copy editing isn't about rewriting—it's about enhancing' and philosophy sections). The tables and checklists are efficient, but the overall length could be tightened without losing value. | 2 / 3 |
Actionability | Highly actionable with concrete examples, before/after comparisons, specific word replacement tables, and clear checklists. Each sweep has explicit 'What to check' and 'Process' sections with step-by-step guidance. | 3 / 3 |
Workflow Clarity | Excellent workflow structure with seven sequential sweeps, each with explicit validation loops ('After this sweep: Return to...'). The iterative process is clearly defined with feedback loops for error recovery. | 3 / 3 |
Progressive Disclosure | Content is well-organized with clear sections, but the skill is monolithic—nearly all content is inline rather than split into referenced files. Only one external reference exists (plain-english-alternatives.md). The checklist and detailed sweep content could be separate files. | 2 / 3 |
Total | 10 / 12 Passed |
