Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses more than the tool name by mentioning symbols, relations, and codebase role, giving the agent a sense of what the summary will contain. However, there are no annotations, so the description carries the full behavioral burden; it omits whether the operation is read-only, how the target file is selected, and what output shape the agent should expect.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
