Marketplace Description Writer

Purpose

This skill creates structured, shopper-friendly product descriptions for marketplace detail pages and independent ecommerce stores. It goes beyond bullet points to build a complete page narrative: an above-the-fold summary that hooks, a benefit-led body that persuades, a specs section that informs, and trust cues that reduce hesitation. Optimized for Amazon product descriptions, Shopify product pages, Etsy listings, and general store detail pages.

Triggers

  • "Write a product description for my Shopify store"
  • "Create an Amazon product description"
  • "Need a full product page for Etsy"
  • "Turn these notes into a marketplace description"
  • "Draft a product detail page"
  • "Write a scannable ecommerce product description"

Workflow

  1. Product & buyer intelligence — Identify product category, target buyer intent (gift, personal use, professional, bulk), and marketplace constraints (character limits, formatting rules, allowed media references).
  2. Claim-safe fact bank — Build a structured repository of verified facts: materials, dimensions, certifications, usage scenes, care instructions, warranty/policy terms, and any differentiation from category alternatives.
  3. Structure selection — Choose a description architecture based on product complexity and buyer journey:
    • Simple products: Benefit hook → 2–3 key features → specs → CTA
    • Complex/technical products: Benefit hook → problem context → solution walkthrough → deep specs → trust section → CTA
    • Emotional/lifestyle products: Scene-setting hook → aspiration → product as hero → social proof → CTA
  4. Section drafting — Write each section with scannable headers, short paragraphs (2–3 sentences max), and natural keyword inclusion without stuffing.
  5. Trust cue insertion — Weave in certifications, policy reminders, origin stories, or material guarantees where they support the buyer's decision.
  6. Review checklist — Provide a final QA list: spec accuracy, claim verifiability, marketplace rule compliance, tone consistency, SEO phrase coverage.

Prompt Templates

1. Full Description Generator (full_description)

Purpose: Generate a complete product description page from a product brief.

Input:

  • ${product_name} — Product name

  • ${length} — Short (200 words), Medium (400), or Long (600+)
  • ${extra_trust_elements} — Certifications, policies, or awards to mention

Output: Structured description with labeled sections, word counts per section, SEO phrase suggestions, and a spec accuracy checklist.

2. Structure Selector (structure_select)

Purpose: Recommend the best description structure for a product type.

Input:

  • ${product_name} — Product name
  • ${category} — Product category
  • ${complexity} — Simple, moderate, or complex
  • ${buyer_intent} — Gift, personal, professional, bulk

Output: Recommended structure with section headers, approximate word allocation per section, and rationale.

3. Tone Adapter (tone_adapt)

Purpose: Rewrite an existing description in a different brand tone.

Input:

  • ${existing_description} — Current description text
  • ${target_tone} — Desired tone (premium, friendly, technical, minimalist, story-driven)
  • ${marketplace} — Target marketplace

Output: Rewritten description preserving all facts, with before/after tone comparison notes.

4. Trust Cue Weaver (trust_weave)

Purpose: Integrate trust-building elements into an existing description without disrupting flow.

Safety Rules

  • NEVER fabricate awards, press mentions, celebrity endorsements, or user testimonials
  • NEVER create false scarcity language ("only 3 left," "selling out fast") unless the seller confirms real inventory status
  • ALWAYS preserve exact specifications — rounding dimensions or weights creates return risk
  • ALWAYS flag any health, safety, or efficacy claims for human review before publishing
  • ALWAYS include appropriate disclaimers for products in regulated categories (supplements, baby, electrical, chemicals)
  • NEVER compare to competitors by name in a way that could be considered disparagement

Examples

Example 1: Skincare Product (Shopify, Premium Tone)

Input: Product="Vitamin C Brightening Serum", Category="Skincare > Serums", Features="15% L-ascorbic acid, vitamin E, ferulic acid, 30ml, airless pump, dermatologist-tested, fragrance-free, vegan", Audience="25–45 skincare-aware women", Marketplace="Shopify", Tone="premium"

Output: Above-the-fold hook focused on the antioxidant synergy science, body paragraphs explaining why vitamin C + E + ferulic acid work together, specs with concentration and packaging details, trust section citing dermatologist testing and vegan certification. No "erases wrinkles" or "guaranteed results" language.

Example 2: Tech Gadget (Amazon, Technical Tone)

Input: Product="Portable Bluetooth Speaker", Category="Electronics > Portable Speakers", Features="IPX7 waterproof, 20-hour battery, 30W output, Bluetooth 5.3, USB-C charging, 360g weight, built-in microphone", Audience="Outdoor enthusiasts, travelers", Marketplace="Amazon", Tone="technical"

Output: Specs-forward description with usage scenario callouts (poolside, hiking, shower), IPX7 explained in plain language, battery life stated with conditions ("at 50% volume"), exact dimensions and weight preserved, Amazon-compatible formatting.
