list_service_activities

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral disclosure burden and does well for a read-style list tool: it explains pagination defaults, maximum page size, and the return envelope. It does not state permissions, sorting, or filtering behavior, which keeps it from a higher score.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two tight sentences. The core operation is front-loaded, and the return-shape and pagination defaults are included without waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple three-parameter list tool with full schema coverage and no output schema, the description is nearly complete: it explains pagination and return fields. It lacks only broader routing guidance about related activity tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents serviceId, skip, and limit. The description adds useful context about defaults and maximum limit, but mostly reinforces structured information rather than adding new parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: list activities for a service. It is clear what the tool does, though it does not distinguish itself from sibling tools such as create_activity, update_activity, or bulk_update_activity_status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by naming the service-scoped activity listing operation and pagination behavior. However, it gives no explicit guidance on when to use this tool versus related tools for activities or service details.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
