eBay

Buy, sell, and flip on eBay with listing optimization, pricing research, shipping calculations, and scam detection.

Security Scan

This is a coherent, instruction-only eBay helper focused on listing, pricing, shipping, and scam-detection guidance and does not request extra credentials or install software.

Purpose & Capability

Name and description (eBay listing/pricing/shipping/scam guidance) match the provided content: all files are guidance documents and there are no unrelated requirements (no binaries, env vars, or config paths).

Instruction Scope

SKILL.md, listing.md, pricing.md, and shipping.md contain only procedural advice for buying/selling on eBay (research, title/description templates, fees, shipping math, scam signs). Instructions do not ask the agent to read system files, access environment variables, or transmit data to external endpoints.

Install Mechanism

No install spec or code files are present; this is instruction-only, so nothing will be written or downloaded during install.

Credentials

The skill declares no required environment variables, credentials, or config paths — appropriate for an advice-only skill that does not integrate with eBay APIs or perform actions on behalf of the user.

Persistence & Privilege

always is false and the skill is user-invocable; it does not request persistent system presence or privileges beyond normal skill invocation.

Assessment

This skill is instruction-only and internally consistent with its stated purpose, so it poses low technical risk. Still consider: (1) The source/homepage is unknown — prefer skills from trusted publishers if you plan to let an agent act on your behalf. (2) This skill cannot perform transactions or access your eBay account (it requests no credentials) — do not paste account passwords or API keys into it. (3) If you plan to let an autonomous agent act on listings, review actions before execution and monitor for unexpected behavior. (4) The guidance is general advice—verify fees, category rules, and legal restrictions on items in your jurisdiction before listing.

Core Rules

1. Research Sold Listings First

Before pricing: search eBay sold listings (filter: Sold Items).

• Use exact model numbers, not generic terms
• Note condition, included accessories, shipping method
• Price range matters more than single data points

2. Title Optimization (80 chars max)

[Brand] [Model] [Specs] [Condition] [Key Features] [Accessories]

• Front-load searchable terms
• No filler words (WOW, LOOK, L@@K)
• Include model numbers, not just names
• Color and size if applicable

3. Fee Calculation

eBay fees structure:

Category	Final Value Fee
Most categories	13.25%
Clothing	12%
Guitars	6%
Heavy Equipment	3%

Plus: $0.30 per order. PayPal/managed payments: ~2.9% + $0.30. Quick estimate: Take 15-17% off sale price for net profit.

4. Auction vs Buy It Now

Use Auction When	Use BIN When
Rare/collectible items	Common items with clear market price
Uncertain market value	Need guaranteed price
Time-sensitive (holiday)	High-value items (>$500)
Building feedback	Consistent inventory

5. Shipping Strategy

• Free shipping converts better but price it in
• Calculated shipping for heavy/bulky items
• Always add handling time buffer (1 day minimum)
• Pack BEFORE listing to know exact dimensions

6. Scam Detection (Seller Side)

Red flags from buyers:

• Requests to ship to different address than PayPal
• "Can you end listing early for $X?"
• Overpayment + request to wire difference
• Pressure for tracking before payment clears
• New account with shipping to freight forwarder

7. Scam Detection (Buyer Side)

Red flags from sellers:

• Price too good to be true (50%+ below market)
• Stock photos only
• Ships from different country than stated
• No returns, vague description, low feedback
• Requests payment outside eBay

8. Return Policy Impact

Policy	Effect
30-day free returns	Higher search ranking, more sales
No returns	Lower visibility, buyers more cautious
Restocking fee	Legal but reduces conversions

Recommendation: 30-day returns for most items (rarely actually used).

Common Traps

• Underestimating shipping → eat costs on heavy items; weigh and measure BEFORE listing
• Ignoring item specifics → listings without specs get buried in search
• Accepting PayPal without verification → chargebacks on high-value items; require signature for >$750
• Pricing from asking, not sold → unsold listings don't reflect market; filter by SOLD
• Shipping before payment clears → "Item Not Received" claims; wait for funds
