Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given for when to use this tool versus the many closely related siblings (ozon_actions_products, ozon_actions_candidates, ozon_seller_action_products_add, ozon_actions_list). The phrase 'seller's own promotion' hints at a distinction from Ozon-mandated actions, but there are no explicit conditions, prereqs, or exclusions. An agent must infer selection criteria entirely from the tool name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
