{"ok":true,"host":"defi-shield-hazel.vercel.app","status":"failed","manifest":{"positioning":"DeFi Shield serves agents that need to gate-check DeFi actions before committing funds or forwarding instructions. It covers the full pre-interaction surface: screening addresses, domains, query strings, and text for injection or fraud; assessing MEV and liquidity risk; comparing chains and bridge routes; and decoding on-chain events. It is distinct from price-feed or DEX-routing hosts — its value is risk intelligence, not market data or transaction execution.","host_overview":"defi-shield-hazel.vercel.app is a security and risk-assessment host for DeFi agents, providing pre-trade safety checks, address trust scoring, MEV analysis, domain reputation screening, and data freshness validation. It does not execute trades, stream live prices, or perform on-chain contract audits. All endpoints are single-shot request/response — no streaming or bulk operations.","routing_guidance":"Use this host when an agent needs to gate-check a DeFi action rather than execute one — specifically for pre-trade token safety, MEV risk, address trust, domain reputation, input injection screening, chain comparison, bridge quotes, or L2 finality parameters. Do not use it for live token price feeds or swap quotes (use a DEX aggregator API such as 0x or 1inch instead), on-chain contract bytecode audits (use a dedicated audit API), real-time block confirmation tracking (use an RPC provider), bulk address screening (this host is single-address per call), or Ethereum mainnet gas estimates (the gas oracle is Base L2 only). The software package scanner is scoped to named ecosystems like npm and is not a substitute for container or runtime vulnerability scanning.","capability_clusters":[{"skill_names":["fetch-address-label","fetch-defi-trust-score","verify-agent-trust"],"cluster_name":"Address & Identity Resolution","cluster_summary":"Resolves
