In this episode of M365.fm, Mirko Peters breaks down why most Copilots in Power Platform fail not because the model is “dumb,” but because the context is — missing system rules, vague identity, no grounding, and undefined tools. He walks you through a complete, repeatable context engineering blueprint for Copilot Studio and Power Automate that eliminates hallucinations, reduces cross‑environment drift, and dramatically cuts latency and cost by giving the model exactly what it needs, and nothing it doesn’t.
WHAT YOU WILL LEARN
This episode is ideal for Power Platform architects, Copilot Studio makers, automation engineers, and governance teams who are under pressure to “add Copilot” without breaking compliance or trust. If your current Copilots sometimes shine and sometimes hallucinate wildly, this conversation gives you a concrete layering model and build recipe you can apply on your next project.
ABOUT THE HOST
Mirko Peters is a Microsoft 365 consultant and digital workplace architect focused on building safe, grounded Copilots and AI agents on the Microsoft cloud. Through M365.fm, Mirko shares practical context‑engineering patterns, governance models, and real‑world stories that help organizations move from demo‑grade Copilots to production‑ready assistants that behave under pressure.

WHAT YOU WILL LEARN
- Why your Copilot fails (context debt): missing system rules, ungrounded Dataverse data, undefined tools, and governance gaps
- Layer 1 — System context that doesn’t drift: enterprise‑ready system messages with identity, scope, refusal policy, schema awareness, and logging rules, plus a “six‑line” pattern you can reuse across Dev/UAT/Prod
- Layer 2 — Retrieval that grounds to Dataverse: how to build a Dataverse‑first schema index, why PDFs and random document libraries are weak grounding, and how to use chunking, security trimming, hybrid search, and caching for speed
- Layer 3 — Tooling and policy enforcement: turning Power Automate flows into safe, least‑privilege “agent verbs,” encoding preconditions and refusal logic, and using DLP, Conditional Access, Purview, and sensitivity labels to keep Copilots inside guardrails
- End‑to‑end build: a step‑by‑step Copilot Studio + Power Automate implementation with schema indexing, tool catalogs, prompt wrappers, environment bindings, and before/after metrics on latency, token usage, hallucinations, and policy adherence
- Models don’t provide truth — they predict text. You provide the truth through system context, retrieval, and tools.
- The four layers (System, Retrieval, Tools, Policies) are the spine of any serious Copilot and the antidote to drift and hallucination.
- Dataverse schema is your grounding backbone; documents and PDFs are secondary evidence, not the primary contract.
- Governance is non‑negotiable: DLP, Conditional Access, Purview, and sensitivity labels define what “safe” means for your Copilots.
- A fully engineered context cuts latency, cost, hallucinations, and audit risk while making behavior predictable across environments.
