getAdmobAccount

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

No annotations are provided, so the description carries full burden. It discloses that the tool queries the Google AdMob REST API v1beta accounts endpoint and returns specific fields. However, it does not mention permissions, rate limits, or that omitting publisherId may fetch default account or list accounts (though that is in schema description). It adds some context but lacks comprehensive behavioral disclosure.

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 sentence of 20 words, front-loading the purpose and explicitly listing the data fields. No unnecessary information.

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 simple single-parameter input and no output schema, the description provides the core purpose and data returned. However, it does not explain the behavior when publisherId is omitted (e.g., returns default account or lists), nor does it describe the return format. Some completeness is missing.

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 coverage is 100% and the schema description already explains the parameter's behavior (omitting fetches default or lists accounts). The tool description does not add additional meaning about the parameter beyond what's in the schema. Baseline 3 is appropriate.

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 clearly states the tool fetches a single AdMob account details (publisher ID, currency code, reporting time zone) from a specific API endpoint. The verb 'Fetch' and resource 'AdMob publisher account details' are specific, and the tool naturally distinguishes from sibling 'listAdmobAccounts' which lists multiple accounts.

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 provides no guidance on when to use this tool versus alternatives. It does not mention when to use listAdmobAccounts instead, nor does it specify any prerequisites or limitations. The inferring from naming convention is insufficient for explicit guidance.

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