RISK

Why instagram_update_media is rated Medium

This tool modifies metadata (caption text) of published media content. While it changes data, the operation is reversible — captions can be updated or deleted by subsequent calls. This qualifies as Write rather than Read (it modifies, not just retrieves) or Destructive (it does not irreversibly delete or permanently destroy content).

From the tool's definition Tool performs 'Update the caption of a published Instagram photo or Reel' — a modification operation on existing data that is reversible (captions can be edited again or removed).
