AI agents call lexicon_get_playlist to retrieve information from Lexicon without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a single playlist object from the Lexicon DJ library without altering state. It is a simple read operation analogous to a database SELECT query, with minimal blast radius if misused by an AI agent.
