Does the description explain when to use this tool, when not to, or what alternatives exist?
The description conveys what this delete does versus the UI action and rules out the fear that deleting a form loses leads, which is genuine usage context. However, it never names alternatives or states when to prefer this over update_form, duplicate_a_form, or leaving the form published, so the guidance is implied rather than explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
