Space Lua

Call the LLM from your own Space Lua code using the silverbullet-ai.chat function.

Basic Usage

local result = system.invokeFunction("silverbullet-ai.chat", {
  messages = {
    {role = "user", content = "What is the capital of France?"}
  }
})

print(result.response)  -- "The capital of France is Paris."

Options

Option	Type	Description
messages	array	Chat messages with role and content
systemPrompt	string	Optional system prompt
useTools	boolean	Enable AI tools (default: false)

With Tools

When useTools is enabled, the LLM can use any tools defined in ai.tools:

local result = system.invokeFunction("silverbullet-ai.chat", {
  messages = {
    {role = "user", content = "Read my Daily Notes page and summarize it"}
  },
  useTools = true
})

print(result.response)   -- The AI's summary
print(result.toolCalls)  -- Tools called (e.g., "> 🔧 read_note(...) → ✓")

Example: Custom Command

command.define {
  name = "AI: Summarize Page",
  run = function()
    local content = editor.getText()
    local result = system.invokeFunction("silverbullet-ai.chat", {
      messages = {
        {role = "user", content = "Summarize in 3 bullets:\n\n" .. content}
      }
    })
    editor.flashNotification(result.response)
  end
}

Multi-turn Conversations
