Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full load. It does disclose defaults for all optional params and promises 'Search results with optional dependency context,' which is useful, but it says nothing about cost/performance of large depth, result limits, or whether the read is purely side-effect free — traits an agent would want before requesting deep dependency expansion.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
