get_children_url_info

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

With no annotations provided, the description must carry the full burden. It discloses the return type and error, but omits pagination behavior, rate limits, auth, or what constitutes a child URL. The behavioral profile is thin for a read operation.

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 well-structured with Args, Returns, and Raises sections, and the purpose is front-loaded. It is concise without excessive fluff, though the Args section somewhat duplicates schema field names.

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?

Given the existence of a nested filter object and pagination, the description is under-specified. It does not explain page size, default behavior, or the semantics of child URL retrieval. Without annotations, this leaves an agent under-informed for correct invocation.

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?

The description adds brief explanations for all four parameters, compensating for 0% schema description coverage. However, filter_properties is only described as 'Properties to filter the results' without detailing the enum options, offering limited added value beyond the schema.

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 'retrieve' and resource 'child URLs of a specific URL', clearly distinguishing it from siblings like get_url_info and get_children_url_traffic_info. The resource and action are unambiguous.

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?

No guidance on when to use this tool versus alternatives. It does not mention conditions, exclusions, or point to sibling tools. The usage context is only implied by the name and parameter list, leaving the agent to infer.

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