🚢 Publishing a declarative agent is not a button. It is a pipeline: approval, distribution, governance, CI/CD, environments. themanifest.dev/blog/publish... #CopilotAgents #DevOps

🔎 Your agent worked in the demo. Then a real user broke it. Good. Now debug with evidence: developer mode, debug cards, tracing, versioning. themanifest.dev/blog/testing... #CopilotAgents #Testing

🧩 The best agent is not the one that knows everything. It is the one that knows who to ask. Compose focused worker agents instead. themanifest.dev/blog/connect... #CopilotAgents #AI

🎯 "It looked good when I tried it" is the weakest line in any agent PR. The Agents Evaluations CLI scores responses and hands you a report to attach. A behavior contract, not vibes. themanifest.dev/blog/agents-... #CopilotAgents

🎯 Your manifest decides whether the agent feels like a prototype or a product. Disclaimers, behavior overrides, response modes, env config. themanifest.dev/blog/advance... #CopilotAgents #ProCode

🛠️ Read-only agents answer. Action-enabled agents operate. API plugins + MCP turn declarative agents into tools that can work with real systems. themanifest.dev/blog/extendi... #CopilotAgents #MCP

🚨 Agents that guess create risk. Ground them in SharePoint, Teams, email, and people data so answers come from trusted sources. themanifest.dev/blog/groundi... #CopilotAgents #AI

📧 Email agents that only search stop halfway. EmailActions lets a declarative agent archive, flag, move, manage rules, create folders, and draft supervised sends. themanifest.dev/blog/email-a... #CopilotAgents #Microsoft365

⚡ Capabilities turn a declarative agent from chat demo into useful tool: knowledge, code interpreter, image generation. themanifest.dev/blog/configu... #CopilotAgents #AI

🔌 An MCP server built for Copilot works with Claude, ChatGPT, and VS Code too. Same server, no rewrites. One manifest entry, OAuth handled by the toolkit. themanifest.dev/blog/mcp-ser... #CopilotAgents #MCP

🚀 Start with an empty folder. End with a deployed declarative agent. The manifest is plumbing. The instructions are the product. themanifest.dev/blog/creatin... #CopilotAgents #ProCode

🔥 Agents that touch business data are production software. Put instructions and plugins in source control. Your team can review each behavior change and roll it back when it breaks. themanifest.dev/blog/why-pro... #CopilotAgents #ProCode

🤔 "Just a prompt wrapper?" Wrong. Declarative agents are full AI assistants inside M365 Copilot — identity, knowledge, plugins. themanifest.dev/blog/what-ar... #CopilotAgents #AI

🏗️ I expected CI/CD for a pure declarative agent to need a deploy stage. It doesn't. atk provision + atk publish cover the path from repo to app catalog. themanifest.dev/blog/cicd-pi... #CopilotAgents #DevOps

🏗️ From npm init to a working Copilot agent in minutes. One command to create, one to provision, one to deploy. themanifest.dev/blog/scaffol... #CopilotAgents #ProCode

⚡ Your lookup agent shouldn't overthink a price check. default_response_mode sets its opening gear: Quick response, Think deeper, or Auto. One line. themanifest.dev/blog/default... #CopilotAgents #ProCode

⚙️ Dev. Staging. Production. .env files per environment, variable substitution in manifests. Switch environments by changing one file. themanifest.dev/blog/environ... #CopilotAgents #DevOps

🎯 "I tried it and it looked good" is the weakest line in agent development. The Agents Evaluations CLI scores your agent and drops a report in the PR. That's when a demo becomes software. themanifest.dev/blog/agents-... #CopilotAgents #ProCode

🚀 A blank text box is a terrible first impression. Conversation Starters showcase what your agent can do from the first message. themanifest.dev/blog/designi... #CopilotAgents #UX

🎨 Your agent can generate images on the fly. GraphicArt = DALL-E-powered generation. One JSON block, no Azure sub needed. themanifest.dev/blog/image-g... #CopilotAgents #AI
