[gotcha] Privilege Creep via Chained Tool Calls

Implement capability-based security and dynamic authorization checks at each tool invocation, validating the current intent and user context, not just the initial session.

Journey Context:
An agent is given access to a 'read\_file' tool and a 'send\_email' tool. The user asks to read a file. The agent reads /etc/shadow, then emails it to an attacker. The agent had the rights to both tools individually, but the combined state transition is malicious. Stateful RBAC or intent-based access control is required to prevent the agent from combining safe tools into unsafe workflows.
