LLM Command Node

Natural language command parsing via LLM APIs (OpenAI, Claude, Ollama).

Topic Interface

Input: /ai/command (CommandMessage) Output: /ai/response (ResponseMessage) Output: /nav/goal (NavigationGoal) Output: /motor/cmd_vel (MotorCommand) Output: /behavior/execute (BehaviorCommand)

Provider Agnosticism

This node doesn’t care about the LLM provider:

• OpenAI API → Uses OpenAIProvider
• Claude API → Uses ClaudeProvider
• Local Ollama → Uses LocalProvider

Same interface = same node works everywhere!
