## Why attach_post_cover_from_job is rated Medium

It does not delete data (Destructive), execute arbitrary code (Execute), or involve financial transactions (Financial).

From the tool's own definition: "The tool description states 'Attach a previously generated ai-media job's output as the post's featuredImage', which modifies post metadata by attaching/setting a cover image. This is a reversible modification of data."
