My test for an agent: would anyone miss it if it disappeared tomorrow? Not "was the demo impressive." Not "did the prompt sound clever." Would someone say: wait, where did that go? I need it. aka.ms/M365AgentsPl... #CopilotAgents

There is a lot of belief around AI agents right now. Some earned, some early, some that has spent too long near a keynote stage. Builders eventually ask: cool, how do I make this work for my users? aka.ms/M365AgentsPl... #Developers

The best agents probably will not feel flashy. They will feel obvious. Right context. Task done without turning it into a project. Knows when to ask instead of guess. "Oh good, this is handled." aka.ms/M365AgentsPl... #CopilotAgents

If AI could retire one phrase from work, I nominate: "Where is that doc again?" The missing link. The buried decision. The source of truth that became a source of maybe. aka.ms/M365AgentsPl... #CopilotAgents

Your future teammate might not need a desk, or have opinions about 25 vs 30 minute meetings. But a good agent still needs what any teammate needs: clear responsibilities, onboarding, context, boundaries, feedback. aka.ms/M365AgentsPl... #FutureOfWork

Building an agent is not just wiring up an API. What job is the user doing? What context does it need? What should it NOT do? How do we know it is improving instead of just sounding confident? Agents need product thinking too. aka.ms/M365AgentsPl...

Every team has the person who knows where the process lives, and gets tagged with "quick question" often enough to deserve an Outlook category. Agents will not replace that expert. They can help them scale. aka.ms/M365AgentsPl... #CopilotAgents

AI agents can sound very sci-fi. Autonomous this, agentic that, a glowing orb on every slide. The part I care about: can a developer build something genuinely useful for a team, and prove it is helping? Less sci-fi. More ship-it. aka.ms/M365AgentsPl... #CopilotAgents

Workday archaeology starts with "I know we discussed this somewhere..." Then: one Teams thread, three tabs, a SharePoint search, a doc named final-final. Agents can shrink that scavenger hunt. Digging into how in the M365 Copilot Agent's Playbook. aka.ms/M365AgentsPl...

AI agents are fun to demo. The real test is less glamorous: what happens Monday morning, when someone just needs to finish one task without opening seven tabs? Joining The Microsoft 365 Copilot Agent's Playbook with Microsoft Reactor. aka.ms/M365AgentsPl... #CopilotAgents

🚀 Work IQ Developer Tools: the developer preview is open. One install, the whole plugin lifecycle. Create, validate, eval, publish, monitor. Same verbs in your terminal, in chat, in CI/CD. aka.ms/wiqd #CopilotAgents #Microsoft365

I had Threads since its inception. Definitely they are scared. It's the first time ever I receive an email from them 🤣
