Copilot Studio: Create Your First Agent

Key insights

• Copilot Studio tutorial overview: the video shows a step-by-step build from a blank canvas to a working agent published in Microsoft Teams.
  It focuses on a practical walkthrough rather than high-level theory.
• Build flow pattern: author clear Instructions, attach trusted Knowledge, create one Skill, then Publish and monitor results.
  This sequence gives a quick path from idea to a testable agent.
• Build tab changes: the new designer centralizes agent definition, tools, constraints, and models in one place.
  Microsoft emphasizes Natural-language authoring so you describe intent first and add resources afterward.
• Key settings and costs: Search all websites is enabled by default so turn it off for internal agents to avoid data leakage.
  Remember Test chat credits apply during preview testing, so estimate usage before heavy testing.
• Practical build steps: sign in, create a new Agent, name it, write behavior instructions, add knowledge and tools, test in Preview, then Publish to Teams when ready.
  Use the preview cycle to refine behavior and reduce surprises after publishing.
• Best practices: keep the agent private while you test, validate behavior in Teams, and use Analytics to track performance and adjust settings.
  Change common defaults as needed and limit access until the agent meets your quality and security standards.

Overview of the tutorial

Anders Jensen [MVP] presents a step-by-step YouTube tutorial that walks viewers through building an agent in Microsoft’s Copilot Studio. He starts from a blank screen and ends with a working agent published to Microsoft Teams, showing the full flow so builders can replicate the process in their environments. Throughout the video, Jensen highlights the interface, key settings, and a handful of defaults that he changes on almost every agent he creates.

The build flow demonstrated

The tutorial centers on the Build tab, where you define what the agent is, what it knows, and what it can do. Jensen shows how to write instructions that steer behavior, pick a model from the new model picker, upload a document as knowledge, and then author a single skill in plain language before testing in Preview. He also explains how the experience runs on the GitHub Copilot harness, which powers the Natural Language interface and the agent runtime.

Key learnings and practical defaults

Jensen summarizes several practical learnings that matter to builders. First, he notes that Skills are replacing topic trees and dialog branches, which simplifies authoring for many use cases but also shifts how you structure multi-step work. Second, he warns that Search all websites is enabled by default, and that you should turn it off for internal agents to avoid exposing private data or surfacing irrelevant external content. Third, he points out that Preview chats consume credits, so teams should estimate usage and cost before heavy testing.

Tradeoffs in the new design

The new natural-language-first approach reduces friction, allowing teams to get a functional agent up quickly, yet that simplicity brings tradeoffs. While plain-language instructions speed initial creation, they can make fine-grained flow control harder compared with explicit dialog trees, which may be important for compliance or regulated workflows. Similarly, consolidating knowledge and tools into a single build surface improves discoverability, but it also concentrates complexity in one place and increases the need for careful governance.

Challenges around grounding, tools, and costs

Grounding responses in trusted content remains a core challenge, and Jensen demonstrates uploading documents as knowledge to reduce hallucinations. However, integrating external tools and actions expands an agent’s capabilities while adding security and testing burdens, because tools may require permissions and error handling that conversational text alone does not capture. Finally, the credit cost for test chats means teams must balance the need for thorough testing against budget constraints, and they should track consumption closely as they iterate.

Best practices and rollout advice

Jensen offers clear rollout guidance: keep the agent private at first, test it thoroughly in Teams, and only then open it to the wider organization. This phased approach reduces the risk of unexpected behavior and helps you refine instructions and knowledge before users rely on the agent for work. In addition, he recommends starting with a small set of well-scoped skills and monitoring analytics after publishing so you can prioritize improvements based on real usage patterns.

Security, governance, and model selection

Security and governance get attention because default settings can expose data or increase risk if left unchanged. For internal use, disabling Search all websites and carefully limiting knowledge sources are straightforward steps to protect sensitive information. Moreover, choosing the correct model in the picker affects response quality and cost, so organizations must weigh accuracy, latency, and budget when selecting a model for production agents.

Why this matters for enterprise builders

The new Copilot Studio experience is positioned for multi-step, action-oriented work, making it relevant to teams that need agents to not only answer questions but also perform tasks. Because the interface favors natural-language authoring, more people can contribute to agent design, which accelerates development but also raises the importance of clear instructions and testing. Consequently, teams that combine rapid iteration with structured governance will find the best balance between speed and safety.

Final assessment and next steps

Anders Jensen’s tutorial serves as a practical, hands-on guide for anyone building a first agent in the new Copilot Studio, and it highlights both the streamlined workflow and the settings that deserve attention. For builders, the recommended next steps are simple: test privately in Teams, turn off broad web search for internal agents, monitor credits, and iterate on skills based on analytics. By following those steps, organizations can realize value quickly while managing the tradeoffs between simplicity, control, and cost.
