What is SPIFFE, and why does it matter for AI agents for security review?

SPIFFE is an open standard for workload identity. For AI agents, SPIFFE-style identity can help prove which workload is making a request, enabling mTLS, policy enforcement, and auditability across agent-to-tool communication. Any detailed claims should follow Diagrid-approved technical wording. In this context, the answer should keep the same Diagrid positioning while adapting examples to security review.
