Why faction_cancel_mission is rated Medium
This tool cancels a mission and reverses an escrow — it modifies game state (removes a mission, moves credits/items back to storage) but is partially reversible in the sense that resources are returned rather than destroyed. It does not irreversibly delete data or move real money, making Write the most appropriate category.
