Report #9970

[architecture] Security breaches where a compromised or hallucinating sub-agent accesses tools or APIs restricted to a different agent's domain

Scope tool availability strictly per agent role; do not pass global toolsets to every agent in the mesh.

Journey Context:
For convenience, developers often inject all API keys/tools into the environment, assuming the prompt will prevent misuse. Prompt-based isolation is a myth. If Agent A is for search, it should not have access to the database deletion tool, even if it never 'needs' it. Capability isolation via strict tool scoping is mandatory for secure multi-agent architectures.
