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 covered. The description adds only a pricing note ($0 USD per request), which is marginally useful, but says nothing about retrieval behavior, the fact that it pulls results of a previously submitted task, or the 30-day window (left to the schema).

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 first sentence is pure boilerplate that promises a field description it never delivers, so it does not earn its place. The only substantive content is the pricing comment, and nothing is front-loaded about the tool's function.

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 exists so return values need not be explained, and annotations cover safety, but the description omits the essential semantics: that this fetches stored results for a task id obtained from the submit tool. For an id-based fetch tool, that missing context is a real gap.

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?

With a single parameter and 100% schema description coverage, the schema already fully documents 'id' (UUID task identifier, usable for 30 days). The description adds nothing to parameter meaning, but per the high-coverage baseline a 3 is appropriate since the schema does the work.

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 the meta-placeholder 'Description of the fields for sending a request:' and then only contains a pricing comment. The actual purpose is carried entirely by the name/title, so the description itself is effectively empty filler rather than a statement of verb+resource.

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 at all, and no differentiation from the closely related siblings such as post_dataforseo_serp_google_jobs_submit (which creates the task) or get_dataforseo_serp_google_jobs_fetch_html. An agent gets zero routing help from this text.

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