Built with:

• Deno + Oak
• Lark Node.js SDK (with Node.js compatibility in Deno)
• btrdb for persisting chat context

By default, user messages are a reply to the last message in the chat (unless the !new command is used).

If the user replies to a previous message in the chat history, a new conversation branch will be created starting from the replied message.

• !new (!reset) - starts a new conversation
  • Note: You can still resume previous conversations by replying to them.
• !system - manages system prompt setting (for current chat)
  • !system - shows the current system prompt
  • !system default - restores the system prompt to default settings
  • !system One line answers by default. - overrides system prompt to "One line answers by default."
