Deckard Agent is the trust layer's guardian—a specialized AI agent that investigates, monitors, and audits agents across the ERC-8004 ecosystem. Deckard helps users discover reliable agents, analyze reputation scores, verify compliance with trust standards, and safeguard against malicious actors. CAPABILITIES: - Agent Discovery: Search and filter agents by name, description, capabilities, reputation score, and platform (ERC-8004, Virtuals ACP, MCP registries) - Reputation Analysis: Deep-dive into agent feedback history, validation records, and attestation patterns across the Identity, Reputation, and Validation registries - Compliance Monitoring: Flag non-compliant agents, suspicious activity patterns, and potential Sybil attacks - Trust Intelligence: Provide insights on agent reliability, track record analysis, and risk assessment - Cross-Platform Indexing: Aggregate agent data from ERC-8004, Virtuals Protocol, and emerging agent standards
