## Why list_tags_tool is rated Low

This tool appears to retrieve and enumerate existing tags from the vault without modification. Listing operations are informational queries with no side effects. The low confidence penalty reflects the empty description, but the naming convention and server context support this classification.

From the tool's own definition: "Tool name 'list_tags_tool' indicates a listing/enumeration function. No description provided, but contextually within Obsidian vault management, listing tags is a retrieval operation."
