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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is known. The description adds no extra behavioral context such as task retention, rate limits, or what the fetch operation returns. It is not contradictory, but it contributes nothing beyond the structured annotations.

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 one short sentence, but it is a useless placeholder rather than a concise statement of purpose. It does not earn its place and leaves the tool's role entirely unexplained.

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 fetch-by-task-ID tool with an output schema and many sibling submit/fetch tools, the description omits what is fetched, that the 'id' references a previously submitted task, and how it relates to the submit counterpart. Even with annotations and an output schema, the description is far too incomplete for correct tool selection.

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%, and the single 'id' parameter is fully documented in the schema as a UUID task identifier usable for 30 days. The description says it concerns request fields but adds no parameter meaning beyond the schema, so the baseline of 3 applies.

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 is a generic placeholder, 'Description of the fields for sending a request:', with no verb and no resource. It does not state that the tool retrieves Google Shopping sellers results by task ID, so an agent would have to rely entirely on the name and title.

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 when-to-use guidance, no when-not-to-use guidance, and no mention of sibling alternatives such as get_dataforseo_merchant_google_sellers_submit or the Amazon equivalent. The description provides no routing information at all.

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