Summary of "Copilot Studio Easiest Way To Upload Files In Chat Window"

Key Technological Concepts and Features:

Copilot Studio Agent Creation:
- How to create a new agent named "file upload agent" designed to receive files via chat and perform actions without needing initial instructions.
File Upload via Chat Window:
- Demonstrated two main methods to upload files to the chat window:
  1. Topic-Triggered Upload:
    - Users trigger a topic by typing commands like "analyze document" or "analyze RFP," which then prompts the user to upload a file.
    - The agent uses a question node to request file upload and detects files by setting the node’s identify property to the file entity type.
  2. activity occurs trigger:
    - The agent triggers automatically whenever a file is uploaded to the chat, without requiring a typed command.
    - This uses a trigger type called activity occurs with a formula condition to check if the attachments table is not empty.
File Validation Logic:
- The agent validates uploaded files by inspecting the system.activity.attachments table, which contains metadata about uploaded files (e.g., content type, file name).
- Validation includes:
  - Checking that only one file is uploaded.
  - Confirming the file extension is PDF (case-insensitive check).
- If validation fails, the agent sends appropriate error messages and loops back to the upload prompt.
Prompt Creation and File Analysis:
- After validation, the file is passed to a prompt tool that uses GPT-4 to analyze the document (e.g., a Request for Proposal (RFP) PDF).
- The prompt is designed to extract key deadlines and deliverable items from the RFP and output them as a bulleted list.
- The prompt is tested within Copilot Studio to ensure correct functionality.
Displaying Results:
- The output from the prompt is captured in a variable (e.g., prompt_output) and displayed back to the user in the chat window.
- Due to a UI bug, the output variable was manually inserted via YAML editing.
Uploading Files to OneDrive:
- In the second approach, after detecting a file upload, the agent uploads the file directly to a OneDrive folder using a OneDrive connector action.
- The file name and content are dynamically fetched from the attachments table.
- Confirmation messages inform the user of the upload success and file path.
Agent Flow Control:
- The use of go-to steps for error handling and end all topics action to prevent unwanted extra responses.
