Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. While it correctly identifies the tool as a read operation, it does not disclose any edge cases (e.g., invalid issue key, permissions required) or behavior beyond the basic function. For a simple get operation, this is adequate but not exemplary.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
