Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the burden of behavioral disclosure. It accurately states the core behavior (run until function return) and references the cdb command ('gu'), but it does not disclose potential side effects, such as whether breakpoints will interrupt execution, or any output behavior. This leaves some room for agent uncertainty, though the operation is relatively simple.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
