Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Debug session loading issues' implies this is a diagnostic/read-only operation, but doesn't specify whether it performs any mutations, what permissions are required, what output format to expect, or whether it has side effects. For a debugging tool with zero annotation coverage, this leaves significant behavioral questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
