Report #93910

[architecture] Compromised or hallucinating agent accesses tools or data restricted to other agents

Scope credentials and tool permissions strictly to the agent's assigned role using short-lived tokens, and enforce capability checks at the tool execution layer, not just at the orchestrator routing layer.

Journey Context:
It is common to give all agents a shared pool of API keys for simplicity. However, if Agent A \(a web scraper\) is compromised via prompt injection, it could use the database-write credentials meant for Agent B. By adopting a Zero Trust model, the tool execution layer verifies the identity and role of the calling agent on every invocation, preventing lateral movement.
