About this tag
The agent control specification tag on WindowsForum.com covers Microsoft's Agent Control Specification (ACS) and its role in governing AI agent behavior. Discussions highlight that ACS is a portable policy format for defining rules, but it does not enforce anything by itself. Instead, the application or framework host must call the policy runtime at the appropriate point in an agent workflow and honor its verdict before a tool executes or data is returned.
