[gotcha] Adding tools to an agent increases its blast radius without corresponding access controls

Implement least privilege by scoping tool permissions per task or session, and require explicit user confirmation for destructive or high-privilege tools.

Journey Context:
It's easy to keep adding tools to make an agent more capable, but each tool adds a new attack vector. If an agent is compromised via prompt injection, it can use \*any\* tool available to it. Group tools by privilege level and only inject the minimum required set into the context. 'Privilege Creep' turns a minor prompt injection into a catastrophic breach.
