list_styles
AI agents call list_styles to retrieve information from HumanizeMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the name alone, this tool retrieves or enumerates available styles for the humanization system. No modification, execution, or destructive capability is apparent. The empty description reduces confidence slightly, but the naming pattern (list_*) strongly suggests a read-only operation consistent with the server's purpose of providing style options for text rewriting.
From the tool's definition Tool name 'list_styles' indicates a listing/retrieval operation with no side effects. Description is empty, limiting evidence.
