Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description only states 'Save' without disclosing side effects such as overwriting, disk persistence, blocking behavior, or handling of unsaved changes. The output schema exists, but the description gives no hint of what the tool returns or does beyond the bare action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
