What problem does it solve? Sellers on the CH△OS decentralized agent network need a safe way to list items on public Nostr relays without leaking PII, while still delivering photos, documents, and gated details to matched buyers over encrypted peer-to-peer MCP channels. ## Core Features & Use Cases - Privacy-safe listing flow: Builds NIP-99 draft events with bucketed numeric facets, strips uniquely-identifying values, mines NIP-13 proof-of-work, and publishes only after explicit user approval. - Gated MCP tool surface: Exposes tools like view_listing, photo/document requests, PII-gated detail requests, and submit_offer, each with a per-call grant policy enforced before content is returned. - Structured negotiation: Handles submit_offer calls with accept, counter, and reject actions, a 5-round cap per counterparty, and status updates (reserved, sold, archived) with NIP-09 deletion cleanup. - Use Case: A user says "sell my item" — the agent collects required facets and minimum photo coverage, drafts a PII-free listing, publishes it to relays, then answers buyer inquiries by delivering photos as MCP ImageContent only after user approval. ## Quick Start Tell the agent you want to sell your item and provide its facets, photos, and documents so it can draft and publish a Nostr listing for your approval.
