Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool returns results from the last executed script, which is straightforward, but lacks details on whether results are cleared after retrieval or what happens if no script has been run. Since the tool is a simple getter with no side effects, the description is adequate but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
