Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the behavioral burden itself. It communicates that the operation is a read of live data and implies a dependency on ratchet_pyth_context, but it does not disclose side effects, error behavior, authentication needs, or data freshness expectations beyond the word 'live'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
