/5 More on the docket:
✅ Real examples of Copilot agents that have landed with users — including a few I built to run Voitanos
✅ "Should I even be using a Copilot agent for this?" (sometimes no — and I'll tell you when)
✅ A few cool tricks I've picked up
/4 A preview of what registrants have already asked me to cover:
✅ How declarative agents stack up vs Copilot Studio agents (this one came up a LOT)
✅ The options, trade-offs, and impacts nobody talks about until you're 3 weeks in
/3 In a few hours, I'll give you a framework for choosing — based on what you're actually building, who it's for, and what your org can realistically support.
/2 SharePoint Agents. Copilot Studio. Declarative Agents with the M365 Agents Toolkit.
Three doors. Microsoft says all three are great.
You have to pick one and live with it.
⏰ Last call: today at noon ET.
A few hours from now I'm going live to answer the question I get more than any other right now:
"Andrew, which agent option should I actually use?"
I don't have a unique process tho...
1. start by putting Claude into plan mode
2. explain what I have (context) & what my desired outcome is (goals)
3. explain validation gates
4. ask "do you have any clarifying q's?"
Then we go back and forth until it creates a plan (that I review & edit).
Sure it happens, but for the most part, that's not been my experience.
Usually, a detailed plan that includes validation checks can self-heal & fix itself. At least that's my experience with Claude Code
exactly!
/7 FREE Webinar: Evaluate Your Microsoft 365 Copilot Agent Options
📅 Tomorrow, April 8
🕛 12:00 PM ET
🎟️ Free — registration required 👉 vtns.io/b5czob
/6 More from the registrant questions:
Real examples of agents getting actual adoption (I'll share a few I built to run my own business)
🤔 "Should I even be using a Copilot agent for this?"
I'll address all of these live, plus whatever comes up in chat.
/5 Looking at questions registrants have already submitted, here's what's on people's minds:
🤔 "How do declarative agents compare to Copilot Studio agents?"
🤔 What are the real trade-offs of each choice?
/4 So tomorrow I'm running a free webinar to cut through it:
👉 Evaluate Your Microsoft 365 Copilot Agent Options
What each option actually does, where each falls down, and how to match the tool to the problem — not the other way around.
/3 But now you've got a new problem: which kind of agent?
✅ SharePoint Agents
✅ Agent Builder
✅ Copilot Studio
✅ Declarative Agents w/ the M365 Agents Toolkit in VS Code
Microsoft says all are great. Not helpful when you have to ship.
/2 Copilot only knows the underlying LLM and what's already in your tenant.
The valuable stuff — manuals, policies, inventory, customer records — lives somewhere else.
Custom agents are how you bridge that gap.
You rolled out M365 Copilot.
Leadership's happy. Press release went out. 🚀
Then someone asks: "Can it answer questions from our SOPs? Our ERP? That SharePoint site nobody's touched since 2019 but somehow runs half the company?"
Out of the box? No. 😳

#VibeCoding and #AgenticEngineering are NOT the same thing.
After months of using AI agents daily, I wrote about where vibe coding falls apart and why agentic engineering is the better path for professional devs.

[7] I wrote a full breakdown covering every change and what it means for developers in the Microsoft 365 ecosystem.
Check it out: vtns.io/atk-6.6-bs
What stands out to you most?
[6] This template cleanup is a clear signal: Microsoft sees the future of M365 development as agent-centric.
If you're still building with the old patterns, now's the time to start learning the new approach.
[5] 🗑️ Microsoft removed 61 project templates from ATK.
Notification bots, link unfurling, message extensions, dashboard tabs, SPFx web parts... all gone.
The toolkit is consolidating around Declarative Agents, Custom Engine Agents, and Foundry Agents.
[4] 🔌 Model Context Protocol (MCP) support for Declarative Agents just went GA.
This is a big deal for how agents interact with external tools and data sources.
[3] 🧠 Embedded knowledge for Declarative Agents is the highlight for me.
Package SOPs, reference docs, and product documentation directly inside your agent. They deploy and version together.
No SharePoint or OneDrive connections required.
[2] 🏛️ GCC-M support is finally here.
If you're building Microsoft Teams apps or Declarative Agents for government customers, you can now target GCC-M environments directly from ATK.
GCC High & DoD are on the roadmap.
Microsoft 365 Agents Toolkit v6.6.0 just dropped and it's a big one.
🏛️ GCC-M support
🧠 Embedded knowledge for Declarative Agents
🔌 MCP going GA
🗑️ 61 templates removed
Here's what you need to know.

The ‘Board of Peace’ started World War 3 so fast.
Microsoft says don't do DOM manipulation in SPFx.
I teach devs the same. But I do it myself.
In this week's newsletter, I shared the responsible approach I follow and the real-world solutions I've built with it.
