Tool-Use Agents

Definition

Tool-Use Agents is agents that call external APIs, databases, simulators, sensors, or effectors to accomplish tasks. In defense applications, it connects reasoning models to real mission systems rather than leaving them as chat-only assistants. The hard part is unsafe tool permissions, spoofed tools, and action without auditability, especially when systems are deployed across contested links, coalition boundaries, and mixed human-machine teams. KhanBMS treats it as a capability only allowed through signed tools, narrow scopes, and reviewable logs, tying the concept back to modular command, edge execution, and auditable authority.
