  "copyPrompt": "Use the Portable Durable Agent Graph Runtime Buildprint. First bootstrap exact snapshots: agb start https://agent-buildprint.com/buildprints/portable-durable-agent-graph-runtime/package.json . If agb is not installed, clone https://github.com/DomEscobar/agent-buildprint and run node agent-buildprint/bin/agb.js start https://agent-buildprint.com/buildprints/portable-durable-agent-graph-runtime/package.json . Then read .buildprint/next-agent.md and continue. Do not write Buildprint snapshots manually. Keep claims scoped to workflow proof and mocked runtime; do not claim LangGraph drop-in parity or production storage equivalence."
