Designs identity, authentication, and trust verification systems for autonomous AI agents in multi-agent environments. Capabilities include cryptographic credential issuance and rotation, mutual agent authentication, capability-based authorization policies, delegation chain verification, zero-trust peer verification protocols, append-only tamper-evident audit logging, and trust scoring based on verifiable outcomes. Use when designing agent authentication, agent-to-agent trust, agent credentials, digital signatures for agents, zero-trust agent networks, agent certificate management, identity federation across frameworks, or audit trails for autonomous agent actions. Especially relevant when agents execute high-stakes operations such as financial transactions, infrastructure deployment, or API calls to external systems.
