ads_network_inventory_list

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

With no annotations, the description carries the full behavioral burden but adds little beyond the operation name. It does not explain whether the call is read-only, what 'optional relay registry' implies operationally, whether pagination applies, or what permissions or setup are required.

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 a single front-loaded sentence with no filler, which is appropriately concise. The terseness contributes to missing semantics but does not violate conciseness itself.

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 list operation with three undocumented optional parameters, no annotations, and no output schema, the description is too sparse. It does not define 'verified', 'relay registry', or what the returned inventory records look like, leaving meaningful gaps for an agent.

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 schema has three parameters (region, status, channel_type) with 0% description coverage, and the description does not mention any of them. It does not clarify how these filters affect the listed offers or what values are accepted beyond the single enum in 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 (List) and resource (verified advertising placement offers) with a clear source (optional relay registry). It does not explicitly distinguish this inventory list from sibling tools such as ads_network_platform_list or ads_network_placement_publish.

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 is given about when to use this tool versus alternatives, nor any prerequisites or exclusions. The description only states what the list contains, leaving the agent to infer usage conditions.

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