RISK

Why set_file_tags is rated Medium

This tool creates or modifies file metadata (personal tags) in Nextcloud. While the operation replaces existing tags, it does not delete files or data irreversibly—tags can be re-applied or cleared. The blast radius is moderate: an agent could overwrite tags on important files, causing organizational confusion or loss of file classification, but the underlying data remains intact and recoverable.

From the tool's definition "Set personal tags on a file or folder in Nextcloud. Replaces all existing personal tags." The tool modifies metadata (tags) on files/folders, which is a reversible write operation.
