[gotcha] Safe individual tools combined to create dangerous capabilities \(Privilege Creep\)

Analyze tool combinations and implement data flow boundaries; restrict which tools can feed data into which other tools \(e.g., file read -> http post\).

Journey Context:
Security reviews often approve tools in isolation. 'Read File' is safe. 'Send Email' is safe. But an agent can compose them to exfiltrate data. The gotcha is that the agent's autonomy makes the sum of permissions greater than the parts.
