Report #61297

[architecture] Overly permissive agents causing security breaches through compromised chain links

Implement capability-based access control \(CapBAC\): agents receive unforgeable capability tokens \(UUIDs with cryptographic signatures\) for specific actions; downstream agents must present capabilities to access tools/APIs; implement principle of least privilege with capability attenuation \(restricting delegation rights\); revoke capabilities immediately upon agent termination or compromise detection

Journey Context:
If every agent has API keys to everything, a compromised or buggy agent in the chain can exfiltrate data or cause damage \(the confused deputy problem\). Capability-based security \(from E language and seL4\) restricts agents to only what they need for their specific task. Capabilities can be revocable, time-bound, and attenuated \(limited further delegation\). This prevents lateral movement if one agent is compromised, containing the blast radius.
