[gotcha] Combining harmless tools creates unauthorized privileged capabilities

Perform a combinatorial risk analysis of tool capabilities \(e.g., 'read file' \+ 'send email' = exfiltration\) and restrict tool availability based on the task context or user role.

Journey Context:
Security reviews often approve tools individually. 'Read file' is read-only \(safe\). 'Send email' is standard \(safe\). But an agent with both can be instructed by a malicious prompt to read '/etc/shadow' or 'id\_rsa' and email it to an attacker. The vulnerability isn't in the individual tools, but in their composition within the agent's capability graph.
