Google ADK article argues tool-call interceptors are the missing safety layer for agents
fhinkel · x · 2026-07-30
The article argues that tool execution security is becoming a major production bottleneck for LLM agents. Because agents can generate side-effecting calls such as database writes or outbound HTTP requests, developers should not execute them blindly.
It proposes tool-call interceptors as the runtime equivalent of memory-safety checks in language runtimes. In Google’s Agent Dev Kit, hooks such as beforetoolcallback let developers inspect tool names and arguments, validate them, and modify the call before execution.
