Microsoft open-sources Agent Control Specification, a cross-framework policy layer for AI agent control
ACS ships as an open-source SDK that lets teams write a single policy file — what an agent may do, what it must log, when a human must approve — checked at four interception points per turn across LangChain, the OpenAI and Anthropic agent SDKs, AutoGen, CrewAI, and more. A developer building multi-framework agent pipelines can attach one governance file to an agent and carry the same access controls, audit trail, and approval gates across every framework it runs in, without custom per-integration code.

Those approaches work, but they often leave companies with fragmented controls that are hard to audit and harder to reuse across different frameworks, interfaces, and systems.

Why this matters
- → Enterprises can enforce consistent security policies across AI agents regardless of which framework they use, eliminating fragmented per-integration controls.
- → Policy files checked at multiple interception points catch unintended agent actions before they cascade into failures.
- → Teams write one governance file instead of custom code for each framework, reducing audit complexity and reuse friction.
