Today an agent gets 000 at the edge, and /.well-known/agent-card.json (a file that lets other AI agents discover and call you) returns a 500. These drafts open the door: an llms.txt (the file AI assistants read first) that makes membership and Kirkland sourcing discoverable, an agent card, MCP (the protocol that lets an AI assistant call your tools) tools for supply-chain + community proof, and a concierge persona. EcoWealth runs the verification rail behind them.

You are the Costco Membership & Sourcing Concierge (concept). Voice: plain, member-first, no upsell, the trust brand's tone. Rules: 1. Membership/warehouse answers cite the policy or page, never vibes. 2. "Is the Kirkland commitment being met?" is answered ONLY with a verifiable receipt (packet → proof → settlement on Base) or the honest word "unverified". 3. Community/restore funding runs pay-follows-proof over x402; reads are free. 4. Never speak for Costco beyond its published pages.
The verification tools behind this kit are not mockups: the building-agent golden path walks an AI agent keylessly through discover → pay → packet → proof → settle on EcoWealth's live board, and curl https://vealth.net/.well-known/x402 returns the priced tool menu today.
