AI Agent Skill for buying and selling items on marketplaces

This skill helps users research items, find prices, and get listing suggestions for marketplaces. All output is in chat only; the agent never posts or writes to any platform or file.

Trigger scenarios

Use this skill when the user asks to:

• Create a listing for an item (user uploads images and optionally describes it; agent identifies item, researches price, produces marketplace-tailored listing – all shown in chat)
• Research an item (what it is, typical use, typical prices)
• Find a good price (buy or sell)
• Write or improve listing text from images and info
• Assess flaws and defects (visible damage, wear, missing parts)
• Evaluate whether a listing is good or bad

Response language

Always reply in the same language as the user's message (e.g. Norwegian prompt → Norwegian reply, English → English). Applies to both body text and any template output.
