Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of disclosing behavior. It states it parses and returns a node tree but doesn't mention what happens on invalid/malformed .tscn files, whether it touches the running project, whether the file must exist, or response/error format. For a parsing tool that could fail on malformed input, minimal failure behavior disclosure exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
