Microsoft Copilot harness brings governed agent loops to Foundry
Microsoft has shown how Foundry agents can move from one-pass prompts to the Copilot harness for planning, looping, subagents and report completion. Hosted agents can also run third-party harnesses with Entra Agent ID, private networking, controlled egress, telemetry, governed toolboxes and organisation-specific benchmark-driven optimisation. It targets production-scale enterprise use.
Microsoft releases its multi-model Copilot harness through Foundry
Microsoft is making the multi-model harness behind Copilot Code, Copilot Studio, GitHub Copilot, the CLI and Visual Studio Code available through Microsoft Foundry. The managed orchestration layer supports more than 20 frontier models, bring-your-own-key access, MCP, agent skills and plugins, while Microsoft runs the agent loop and sandbox.
Copilot Studio unifies apps, workflows and agents in one build environment
Microsoft’s September Copilot Studio update adds public-preview app creation alongside workflows and agents. Makers can generate interfaces from natural-language requirements, retain code access and deploy through a managed runtime with identity, governed data, lifecycle controls, Git-backed versioning and central visibility across Microsoft’s connected agent-building surfaces.
