Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It clearly reveals that the operation removes multiple underlying artifacts (vectors, BM25 index, and JSON), signaling a destructive, irreversible action. It does not mention permissions or idempotency, but the core behavioral impact is well communicated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
