Report #57649

[frontier] API keys shared between agents create blast radius security risks

Adopt UCAN \(User-Controlled Authorization Networks\) tokens for capability-based delegation: agents issue attenuated UCANs to sub-agents with specific action scopes, verifying cryptographically without central authority

Journey Context:
Traditional API keys between agents mean if one agent is compromised, all keys are exposed. OAuth2 helps but requires central IdP. UCANs \(from IPFS/Filecoin ecosystem\) allow agents to delegate capabilities cryptographically in a DAG structure. This is emerging in decentralized agent frameworks. Tradeoff: complexity of key management vs security. Alternatives: SPIFFE/SPIRE but UCANs fit better for cross-organizational agent delegation.
