(00:05:01) Building a Custom Engine Agent

n this episode of M365.fm, Mirko Peters explains why out‑of‑the‑box Microsoft 365 Copilot fails on real‑world enterprise questions — and how custom agents turn it from a clever generalist into a governed specialist that actually follows your rules.
WHAT YOU WILL LEARN
Copilot isn’t broken — it’s blind to your world. By default, it doesn’t know your exception lists, approval chains, escalation rules, regional variants, or internal APIs, so it answers from generic Microsoft patterns and best practices. That works for low‑risk questions and fails spectacularly when users ask, “Are we allowed to…?” or “What is the process here?”Custom agents fix this by giving Copilot a specialist to talk to. Instead of guessing, Copilot routes the hard questions to an agent that can search your curated content, call your systems through safe tools, and then return grounded, policy‑correct answers with clear citations. The moment you upgrade your manifest and wire in a custom engine agent, Copilot stops improvising on critical topics and starts behaving like part of your operating model.

WHAT YOU WILL LEARN
- Why default Copilot gives “nice” but wrong answers about your policies, DLP exceptions, escalation paths, and regulated processes
- How Copilot’s standard grounding (Graph + public info) misses local reality: your playbooks, exceptions, SLAs, and approval rules
- What custom engine agents are: specialized brains connected to your own indexed content, APIs, and tools
- How a custom agent uses retrieval (Azure AI Search), tools (internal APIs like CheckOnCallSchedule or ValidateCustomerId), and guardrails to answer correctly
- Why upgrading your manifest to schema 1.22 and adding copilotAgents/customEngineAgents is the key step most tenants are missing
- How to design narrow, high‑value agents (for support policy, HR, security, or operations) instead of one “do everything” monster
- How to run agents as products: environments, versioning, evaluation, and clear ownership
