Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. It implies a read-only operation ('Get') but doesn't disclose details like authentication requirements, rate limits, error conditions, or what 'positions' entail (e.g., types of assets, formatting). This is inadequate for a tool with potential financial data sensitivity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
