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 structurally. The description adds only a pricing note ($0 USD reference per successful request, account pricing may differ), which is genuine cost context but is generic boilerplate rather than tool-specific behavior. No contradiction with 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?

It is short, but brevity is not conciseness here: neither sentence describes the tool, and the purpose is never front-loaded. The stub line plus a pricing comment are filler occupying the entire description.

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 and the single parameter is fully documented, so return values need not be explained. What is missing is the one thing the description alone must supply: what the tool actually does and when to call it instead of the sibling fetch/submit tools.

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% for the single id parameter, and the schema itself richly documents the UUID format and the 7-day reuse window. The description adds nothing to parameter meaning, 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 placeholder stub ("Description of the fields for sending a request:") followed by auto-injected pricing boilerplate. It never states the verb or resource, so an agent gets no confirmation that this fetches stored Google Jobs SERP HTML for a prior task id. It is worse than a tautology because it does not even restate the name or 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?

No when-to-use, when-not-to-use, or alternative is given, despite siblings like get_dataforseo_serp_google_jobs_fetch and post_dataforseo_serp_google_jobs_submit that an agent must choose between. The only routing signal available is the tool name itself.

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