An Agent SDK is a developer toolkit for building AI agents that can call tools, read and write files, and execute commands as part of an automated workflow. Instead of a chat-only assistant, it helps create software that can act on behalf of a user or system, follow steps, and retry tasks when something fails.
In cyber security, that extra capability is also extra risk. An agent with tool or shell access can be steered by malicious prompts, exposed secrets, or unsafe inputs into leaking data, modifying files, or running unwanted commands. In real defenses, teams treat Agent SDK deployments like other privileged automation: they sandbox execution, restrict credentials, approve sensitive actions, log tool calls, and watch usage telemetry for loops or abuse. Used carefully, the SDK enables efficient automation; used loosely, it can turn an AI workflow into a broad attack surface.
