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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered elsewhere. The description's only added behavioral content is a pricing line, which is generic boilerplate rather than useful operational context (no latency, quota, or result-availability notes).

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?

It is short, but not concise in the useful sense: the leading sentence is a dangling placeholder about field descriptions that are never delivered, and the remaining content is an embedded pricing comment block. Nothing is front-loaded and no sentence earns its place.

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?

An output schema and rich annotations exist, so return values and safety need not be explained. Still, the description fails to say that this retrieves previously submitted ASIN task HTML results by task id, leaving an agent to infer the tool's role entirely from the name and title.

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 there is a single parameter, whose UUID format and the 7-day result-retention window are fully documented in the schema. The description adds nothing beyond that, so the baseline 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 never states what the tool does; it opens with a generic boilerplate header ('Description of the fields for sending a request:') and the only substantive text is a pricing remark. Nothing distinguishes it from siblings like get_dataforseo_merchant_amazon_asin_fetch or ..._products_fetch_html.

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 mention of the submit/fetch workflow, and no reference to any sibling tool. An agent gets zero routing signal from the description.

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