Notes from real projects. What worked, what didn't, and why — no marketing spin.
Microsoft now hosts the code that Copilot and other AI tools build. For architects, that moves governance from the build tool to the runtime. Here is what that changes, what it does not solve, and what to design before the first AI-built app goes viral.
Microsoft's October 15, 2026 announcement gives Copilot Studio agents their own accounts, shared business process memory, and triggers. I argue that organizations should treat each agent like a service account with a job description and decide early which agents they want to own.
Part two of a short, living series on Copilot and agent costs. Where Microsoft 365 Copilot services, Copilot Studio, and Foundry agents show their costs, which controls stop spending, and how to build chargeback across three admin experiences.
Part one of a short, but living series on what Copilot and agents cost. What the Copilot license costs, how Copilot Credits work, which features use them, and what Microsoft has announced next.

Building long-running business processes in Copilot Studio using standard harness, state tables, agent flows, and multi-agent orchestration. Boring but effective and save
Child agents, connected agents, A2A, MCP, and the new skills: which of them exist in which harness, why, and how I decide before a single agent gets built.
The new workflows experience: Here is what the agent node does, where it belongs in a build, and the boundaries I now check before I ship one.
What I have learned running Copilot Cowork in real tenants: how to enable it (including the EU data-boundary decision), what the skills actually do, where the limits bite, and what is coming.
With agents, a single request can fan out into model calls, retrievals, retries, and tool actions that cost far more than the prompt suggests. Here's how I measure, allocate, and govern that full cost — not just the token line — and tie it to outcomes.
This write-up shows how to build Skills in the new Copilot Studio agent experience. It covers the SKILL.md format, bundling scripts and resources, authoring and uploading, how the orchestrator uses them, and governance. It is separate from the legacy Bot Framework skill.
I connect enterprise AI architecture with practical implementation, and share what I learn along the way.
I’m a Principal Architect at NTT DATA, Microsoft MVP and Microsoft Certified Trainer (MCT), based in Berlin. My work focuses on agentic AI, intelligent automation, and the Microsoft ecosystem. I help organizations move from promising demonstrations to secure, scalable, well-governed solutions. That means connecting technology choices with business processes, enterprise data, operational ownership, and measurable outcomes.
