Nostr Marketplace Builder

Overview

Construct correct Nostr marketplace events for commerce applications. This skill handles the non-obvious parts: stall/product relationships, shipping cost calculations, auction lifecycle rules, checkout message sequencing via NIP-04, and P2P order tag structures from NIP-69.

When to Use

• The task involves Nostr marketplace primitives such as stalls, products, auctions, bids, checkout messaging, or NIP-69 orders.
• The user is building commerce flows on Nostr rather than generic social posting.
• The request needs event structures or workflow guidance for merchant listings, shipping, bidding, or order state.
• The problem is marketplace-specific behavior under NIP-15 or NIP-69.
