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 behavioral traits. The description only states 'Remove PII' but does not specify whether this modifies the insights in place, returns new sanitized data, requires specific permissions, or is reversible. For a mutation-like tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
