get_dv360_advertiser

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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds essentially no behavioral context beyond restating that this is a read of settings; it does not explain error conditions, permissions, or what 'settings' includes.

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 single sentence is front-loaded and waste-free. Its terseness is more an issue of missing context than of poor structure, so it fits the conciseness dimension well while leaving completeness gaps elsewhere.

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?

Although the tool is simple and has an output schema, the description leaves both input parameters undocumented and does not clarify how this differs from the list endpoint. For a get-by-id tool with zero schema descriptions, this is insufficient to call correctly without opening the schema.

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 0%, so the description carries the full burden for two parameters. It implies advertiser_id identifies the advertiser, but says nothing about the optional 'account' parameter or the expected format of advertiser_id, leaving a meaningful gap.

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: read one DV360 advertiser's settings. It is clear what the tool does, but it does not explicitly distinguish this from the sibling list_dv360_advertisers tool, leaving the agent to infer that this is single-record retrieval.

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?

There is no explicit guidance on when to use this tool versus list_dv360_advertisers or how to obtain the required advertiser_id. The word 'one' weakly implies single-item lookup, but no alternatives or conditions are stated.

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