## Why hires_add_candidate_tags is rated Medium

This tool modifies candidate records by adding tags (metadata), which is a reversible write operation. It does not delete data, execute code, move money, or trigger external side effects. However, it affects recruiting workflow and candidate visibility, so severity is medium rather than low. The confidence is high because the action is clearly stated as 'add tags' without ambiguity about side effects.

From the tool's own definition: "Tool name 'hires_add_candidate_tags' and description states 'Add one or more tags to a candidate' — this creates or modifies candidate metadata in the ATS system."
