• Semantic Kernel Sample Skills

Demo Script

Setup

1. Run all 3 plugins with start.bat
2. Run the Semantic Kernel Chat Copilot Locally with ~\scripts\start.ps1

Learning Notes

These are the learnings from my experimentation so far...

1. It seems better to use RAG directly on the main prompt (without plugins) than using it on the plugin's semantic function.

• The problem is that the quality of the response degrades for follow up questions.
• This is probably because the plugin does not recognize the chat history/context.
• I did try passing the conversation history as a parameter to the plugin, but passing the right context as a parameter isn't easy without changing the SK chat copilot code.

2. Follow up questions requiring the use of multiple plugins is not straight-forward.

• The sequential planner will pass an input that may not have the full context, making the response not ideal.
• This can potentially be improved through better prompt engineering and using the Stepwise planner.

3. Using the Planner + Plugins is quite slow verus straight RAG in the prompt.

• This is expected, but it is still worth noting.
• This can be improved using predefined plans, but the chat copilot app does not support this yet for me to test further.
