Product Comparison & Review Copywriter
Purpose
This skill generates fair, structured product comparison content — head-to-head comparison tables, category buying guides, balanced pros/cons analyses, specification battles, and personalized "best for" recommendations. It is built with fairness as a first principle: the output must be useful to readers making purchase decisions, not a disguised sales pitch. Designed for e-commerce product pages, editorial content, affiliate marketing, and merchant category pages.
Triggers
- "product comparison"
- "product VS"
- "对比评测"

- "pros and cons"
- "选购指南"
- "compare products"
- "spec comparison"
- "best for recommendation"
- "优缺点分析"
Workflow
- Receive products to compare from user: Product A and Product B (or a category with multiple entries), with key specs, price points, target users, and any sponsored/editorial disclosure.
- Build a feature comparison matrix: list all comparable features across both products, note where data is missing.
- Generate balanced pros and cons for each product — a MINIMUM of 2 pros and 2 cons per product, even for the recommended one.
- Create "best for" recommendations based on user personas, not product superiority: "Product A is best for [persona/use case], Product B is best for [different persona/use case]."
- Apply the fairness gate: verify no invented weaknesses, no suppressed advantages, no defamatory language.
- Output the complete comparison package: feature table + pros/cons + buying recommendation + fairness disclosure.

Output Format
Every comparison is delivered in a reader-friendly structure:
Feature Comparison Table:
| Feature | Product A | Product B | Edge |

Pros & Cons:
- Product A
- ✅ Pro 1: ...
- ❌ Con 1: ...
- Product B (same structure)
Verdict: Best for [persona/use case] → [which product and why]

- NEVER use defamatory, dismissive, or insulting language about any product
