Report #74720

[architecture] Agents in a shared chain inherit overly broad permissions, allowing a compromised or hallucinating agent to execute tools meant only for a different agent

Scope tool credentials and permissions strictly to the agent's specific task node, passing short-lived, scoped tokens down the chain rather than sharing a global credential environment.

Journey Context:
In multi-agent setups, developers often inject a single API key \(e.g., a database password\) into the environment, assuming all agents are trusted. If Agent A \(a web scraper\) gets prompt-injected, it can suddenly use Agent B's database deletion tools. By treating each agent as an untrusted microservice and issuing scoped tokens \(e.g., read-only for Agent A, write for Agent B\), you limit the blast radius. The tradeoff is the complexity of token management, but it prevents a single agent compromise from taking down the whole system.
