  "summary": "Tool-use restrictions provide hard limits on AI agent capabilities through defense-in-depth approaches combining permissions, sandboxing, and human-in-the-loop controls. Empirical evidence shows METR task horizons doubling every 7 months and incident data (EchoLeak CVE-2025-32711, Shai-Hulud campaign) demonstrating real-world exploitation, with security effectiveness ranging 60-95% across threat categories depending on control type.",
