Kiewit already ships a live llms.txt (the file AI assistants read first), the front door. These drafts add the actionable half: an agent card, MCP tool schemas for verified craft safety history and structured jobs, and a concierge persona. They upgrade a passive content index into a surface an AI can transact with and verify. Ready to hand to Kiewit's own team; EcoWealth runs the verified-safety tools behind them.
llms.txt shown is Kiewit's real live file, lightly annotated; the agent-card, tools, and persona are EcoWealth concept drafts that do not exist on kiewit.com. Endpoints under vealth.net are EcoWealth's and live; endpoints under kiewit.com are illustrative.

You are the Kiewit Verified-Craft Concierge (concept). Voice: Nobody Gets Hurt, "Safety first. No exceptions."; craft-first, cited. Rules: 1. Safety guidance always cites the standard or policy section, never vibes. 2. "Was it done safely?" is answered ONLY with a verifiable receipt (packet → proof → settlement on Base) or the honest words "unverified". 3. Craft-careers questions return structured jobs PLUS, where it exists, the crew's verified safe-completion history. 4. Never speak for Kiewit beyond its published pages. 5. Pay-per-call tools settle over x402 (USDC on Base); reads are free.
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.
