Creating agent using Copilot Agent Builder

I utilized Agent Builder to construct an Agent, incorporating skills designed to generate slides using a default template. However, the output did not meet my expectations. I am uncertain if this is because Agent Builder is restricted to generating text and content alone, rather than both producing content and beautifying my slides, despite me explicitly specifying this in my skills.

My intended workflow is to retrieve the content; if an image is present, the agent should extract all the material and organize it for the user to review. If the information is incorrect, the user must manually input the text in the chat; otherwise, they can simply click confirm. Following that, once the text is organized and analyzed, the agent should build the presentation using default templates—complete with speaker notes—and generate visual charts or AI images, ensuring the content maintains a specific writing style.

I have consolidated all of these steps into a single skill. Should I segment them into separate skills instead? Additionally, is it possible to create a prompt that both generates and beautifies my slides?
