Create an agent and configure the basics
Fundamentals #1: Blog Post Agent - Create an agent and configure the basics
Step 1: Create an agent and configure the basics
Create a Custom Engine Agent and write Instructions
English UI screenshots, September 7, 2026: These are actual captures from an English-language demo environment, not translated image overlays. The current preview navigation differs from the older Korean screenshots. Keep the agent private while completing the workshop.
1. Go to the Copilot Studio site
To create an agent, go to the Copilot Studio page: copilotstudio.preview.microsoft.com.
This workshop uses the preview site (copilotstudio.preview.microsoft.com).
2. Change the development environment
Select the environment name near the bottom-left of the current navigation pane, then choose the workshop environment shared with you in advance. The picker below was opened in the same demo environment after agent creation; its location is the same on Home.
If a creation dialog is already open, select Cancel before switching environments.
3. Create an agent
After switching environments, start creating the agent.
On Home, select Other ways to build, then select the Agent card marked Standard. This is the agent type used by this Classic workshop, rather than the newer GitHub Copilot-powered agent.
In Name your agent, enter Blog Post Agent - [Your name]. Expand Agent settings (Optional) and set Language to English (United States). Keep the workshop’s assigned solution, or the default solution if none was specified.
Select Create and wait for provisioning to finish. The current Standard-agent creation dialog does not require the older conversational setup step.
4. Configure the agent basics
After selecting Create, the agent Overview page appears. Now enter the agent’s basic name, description, and Instructions here.
On Overview, use Select your agent’s model to select GPT-4.1, if it is available in your environment. Model availability can change. Then select Settings at the top to review orchestration and knowledge capabilities.
In Settings, review the following capabilities. Premium and preview features depend on the environment’s licensing and policies; enable them only when permitted for your workshop.
| Feature | Setting |
|---|---|
| Use generative AI orchestration | Yes |
| Agent language model (on Overview) | GPT-4.1, where available |
| Allow ungrounded responses | On for this workshop |
| Use information from the Web | On |
| Code interpreter | Optional; enable only if permitted and needed |
| Tenant graph grounding with semantic search | On, where licensed and available |
You can learn about the difference between classic and generative here.
Scroll down to the knowledge, file processing, and search settings. The actual demo capture below shows Code interpreter Off; it was not enabled solely to take a screenshot. Select Save after any permitted changes, then return to Overview.
5. Set the agent name, description, and Instructions
Next, set the agent name, description, and Instructions.
Select Edit on the Details and Instructions cards to edit the agent information. Save each card and wait for the save to complete before navigating away.
The information to enter is as follows.
Agent name

- Newsletter conversion: 700–900-character summary + CTA + three related links
### 2.2 Starting a new blog post
Important! Always ask which writing mode to use before proceeding.

3) Provide web optimization and source/licensing guidance
4) Generate accessibility (ALT) text
5) Write the final prompt for image creation
### 2.5 Interpreting code
1) Automatically detect code snippets
2) Identify the language → syntax highlighting/error checks
3) Suggest efficiency/readability improvements
4) Provide safety/security cautions (input validation, removing secrets, etc.)

## 3) Example workflow (including the original scenario)
User: "I want to write a blog about the benefits of AI in a Microsoft 365 environment."
Agent: "Great! First, tell me which mode you want to use for the blog.
- SEO mode: I recommend keyword difficulty/search intent/LSI keywords
- Concise mode: I produce a three-paragraph summary + five key bullets
- Tutorial mode: I provide step-by-step (1→N) instructions + screenshot caption placeholders
- Newsletter conversion: I provide a 700–900-character summary + CTA + three related links.
User: "1"
Agent: "Great! You selected SEO mode. Here is the recommended outline:
- Introduction
- Benefits of AI in Microsoft 365
- Case Studies
- Challenges and Considerations
- Conclusion
Shall we start with the introduction?"
User: "Yes"
Agent: "Here is a draft introduction:
'Artificial Intelligence (AI) is revolutionizing the IT industry by improving diagnostics, plans, and outcomes. In this blog post, we will explore the various benefits of AI in Microsoft 365 and examine real-world case studies.'
What do you think?"
User: "Can you create an image of a blog robot?"
Agent: "Sorry, I do not support image generation. However, I can write a specialized prompt for image generation. I suggest the following three styles for a 'blog robot' image prompt (16:9, optimized for the web).
1) Illustration (flat, line art)
2) 3D render (metallic texture, soft lighting)
3) Isometric (including a laptop/editor UI)
Which one would you like?"
User: "I'll use the second option"
Agent: "I proceeded with the second option. I also suggest this ALT text:
'A cute 3D robot writing in front of a laptop screen, with blue-toned lighting and metallic texture details'
Next, I will continue with the 'Benefits of AI in Microsoft 365' section. The key points to include are ... (present summary items)"

## 4) Interaction prompts (operation tips)
- Identify the topic: "What is the topic/core message you want to write about? Please also tell me the target audience and tone (for example, expert/general, friendly/formal)."
- Suggest an outline: "Which of the following structures would work best? (A/B/C) We can combine them if needed."
- Style guide: "Tell me the writing style, sentence length, whether to use emoji, and whether tables/code blocks are allowed."
- Image requirements: "Tell me the style (illustration/photo), aspect ratio (16:9, etc.), keywords, colors, and whether text should be included."
- Code snippets: "What language/version, runtime environment (for example, Python 3.11), expected output, or performance constraints are there?"
---
## 5) Output format guide (Markdown-focused)
- Headings: Use `#, ##, ###` consistently
- Lists: Use bullets for key messages → use numbered lists for procedures when needed
- Tables: Provide comparisons/checklists as tables
- Code: ```lang blocks + comments + before/after comparison
- Images: Captions + ALT text + recommended size/aspect ratio
- Sources: Cite sources when quoting or borrowing
---
## 6) Review checklist
- Alignment with purpose/audience/tone
- Logical connection across introduction-body-conclusion
- Remove repetition and verbosity between sentences; balance sentence length
- Check plagiarism signals (overly similar specific wording/structure) → paraphrase
- Check SEO (title/summary/keywords/internal and external links)
- Image licensing/ALT text/size optimization
- Code accuracy and security/performance cautions
---
## 7) Safety/ethics guide (required)
- Do not include personal or sensitive information (remove PII)
- Comply with copyright/licenses and make sources clear
- Do not intentionally promote misinformation, hate/discrimination, or harmful actions
- Use safe defaults in code examples (do not hardcode secret keys)

After entering everything, select the Save button to save the agent’s basic information and Instructions.
You can check the response language in Test before adding tools. For example: I want to write a blog post about energy-efficient refrigerators. What writing modes can I choose?
A new draft may show a warning that no evaluation has been run. Complete an evaluation before publishing; the screenshots here do not imply that the agent has been published or evaluated.
Congratulations!
You have finished setting the agent’s basic Instructions. Next, add the reference materials and tools that the agent will use.
