What replace_tags_in_notes does on Anki

Why replace_tags_in_notes is rated Medium
This tool modifies existing data (tags on notes) reversibly—tags can be changed, removed, or re-added without permanent loss. It does not delete notes or destroy data irreversibly, nor does it execute arbitrary code. The empty description reduces confidence slightly, but the clear intent from naming and sibling context (add_tags_to_notes, add_notes) places it firmly in Write category.
From the tool's definition Tool name 'replace_tags_in_notes' indicates modification of note metadata (tags) in Anki. Sibling tools like 'add_tags_to_notes' confirm tag manipulation is a core server capability.
