Debugging a LiveKit agent live

lk agent debugger runs the user's agent locally as a background process in text mode and lets you drive a conversation one turn at a time. It's built for coding agents: you play the user, choose each next line based on the last reply, and inspect what the agent did in between.

Speech is off and nothing goes to a LiveKit room, so a turn costs only the agent's own LLM and tool calls. That's cheap enough to use constantly while building.

Before the first use, confirm the command exists and read its help:

lk agent debugger --help

The help is thorough and is the source of truth for subcommands and flags, so this skill doesn't restate them. If the command is missing, the installed CLI predates it. Tell the user to update lk and use testing-livekit-agents until then. Don't guess at an older command's shape.
