Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior, but it is sparse. It claims to list 'all projects' while the schema has a status filter with a default of 'ativo', which contradicts the 'todos' wording—potentially misleading an agent about the default scope. It also fails to mention any side effects, permissions, pagination, or response format, which are critical for a tool without annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
