Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses that the tool performs multiple mutating actions: creates initial RED assessments, collects auto-evidence from live sources, and re-assesses. It also states the return value (readiness score). However, it does not address idempotency, reversibility, or prerequisites.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
