The primary focus of this update was the introduction of Agentic Actions and Dynamic Chaining, shifting the platform from simple conversation-based triggers to reasoning-based autonomous execution.
Real-time User Journey: Dynamic Chaining
The core “journey” updated in July 2025 involves how an agent handles a multi-step request without manual “if/then” branching:
- Complex Prompt: A user asks, “Find the latest sales report for the Northeast region, summarize the top three concerns, and email that summary to the Regional Manager.”
- Reasoning: Instead of looking for a specific pre-built “topic,” the agent uses its Generative AI orchestrator to identify the necessary steps.
- Dynamic Action: The agent autonomously “chains” together three separate tools:
- Tool 1 (SharePoint): Searches for and retrieves the specific PDF/Excel file.
- Tool 2 (LLM Reasoning): Analyzes the content of that file to extract the top three concerns.
- Tool 3 (Outlook): Drafts and sends the email to the specific contact.
- Completion: The agent confirms the email has been sent and provides a copy of the summary to the user in the chat.
Step-by-Step: How to Enable Dynamic Chaining
To move your agent from “Classic” mode to the new “Agentic” reasoning mode:
- Step 1: Open Agent Settings: In Microsoft Copilot Studio, select your agent and go to the Generative AI page in the side navigation.
- Step 2: Switch Orchestration: Under the “Orchestration” section, select Dynamic Chaining (Preview). This allows the agent to use generative AI to choose the best topic or action to fulfill a request.
- Step 3: Add Actions: Navigate to the Actions tab. Add the specific “skills” the agent can use (e.g., pre-built connectors for Outlook, SharePoint, or custom Power Automate flows).
- Step 4: Refine Descriptions: For every action, provide a clear, natural language Description. This is critical, as the agent uses these descriptions to “know” when to trigger that specific tool.
- Step 5: Test & Publish: Use the Test Pane to verify the agent can correctly chain these tools together before publishing to your users.

The July 2025 update defined a clear evolution of the platform’s architecture:
| Feature | Traditional Bot (Legacy) | Agentic AI (New) |
| Logic Engine | Fixed Topic Triggering (Keywords) | Generative AI Orchestration |
| Workflow | Linear/Pre-defined Paths | Dynamic Chaining (Reasoning-based) |
| Tool Integration | Manual API Calls | Autonomous Tool Use via Descriptions |
| User Inputs | Specific Phrases Required | Complex, Multi-intent Prompts |
