Using PromptBuddy

Mix.install([
  {:kino_promptbuddy, path: Path.join(__DIR__, "..")},
  {:kino, "~>0.17.0"},
  {:mix_install_watcher, "~> 0.1.0"}
])

The context is all precedent cells

User:

Hi, what is your name? And what is your model?

Buddy:

Hi! I’m Claude, made by Anthropic. I’m Claude 3.5 Sonnet.

How can I help you with coding today?

User:

Do you know my name?

Buddy:

No, I don’t know your name. You haven’t shared it with me yet in our conversation.

Would you like to tell me your name? And is there a coding problem I can help you with today?

My name is Fred.

Now Buddy knows my name

User:

Write me a poem.

Buddy:

Here’s a short poem for you, Fred:

Code and logic intertwine,
Functions flow like morning wine,
Bugs emerge, then fade away,
Better code at end of day.

What kind of coding help do you need?
