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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is covered. However, the description adds zero behavioral context of its own and offers only filler text. There is no contradiction with the annotations, but there is no added value either.

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 the single sentence is filler that does not describe the tool. Brevity that conveys nothing is not conciseness; the sentence does not earn 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?

For a results-retrieval tool that must be paired with a submit task and is only valid for 7 days, the description supplies none of that connective context. Although an output schema exists, the description still omits the essential fact of what operation this is.

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 only one parameter, so the schema already carries the semantic load (UUID task id, 7-day validity). The description contributes nothing on top, which is the expected baseline of 3 when the schema is complete.

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 boilerplate ('Description of the fields for sending a request:') that says nothing about what the tool does. It never states that it fetches Amazon ASIN HTML results, nor distinguishes it from get_dataforseo_merchant_amazon_asin_fetch or the sibling HTML-fetch tools.

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 usage context whatsoever: no when-to-use, no prerequisite (e.g. that a submit task must run first), and no reference to any alternative like get_dataforseo_merchant_amazon_asin_fetch. The agent is left to infer everything from the tool name.

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