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

Annotations declare a destructive, non-idempotent, open-world write operation, but the description says nothing about task submission, asynchronous execution, billing (cost per SERP, priority surcharge), or that it enqueues work rather than returning results synchronously. Contrasted against an endpoint that returns a completed list, the description misleads about the operation's nature.

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?

Two short sentences, front-loaded, with no waste — but the brevity stems from under-specification rather than discipline. It is concise but says nothing that 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?

For a destructive, billed, asynchronous task-submission endpoint with a rich nested schema, no annotations context, and a subtle task/fetch workflow, the description is completely inadequate. It never explains what the call does, how results are retrieved, or any of its many optional parameters.

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 0% against the outer body object, and the description adds zero parameter detail. It never mentions keyword, depth, tag, priority, pingback_url, or postback_url — all of which are only described deep in nested item schemas, not at the tool level.

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 describes the endpoint's OUTPUT ('provides a list of business profiles listed on the Trustpilot platform'), not the action the tool performs. The name says 'submit' — this tool creates/submits a search task — but the description never states that. It's essentially a tautological restatement of what the endpoint returns, and it doesn't distinguish this task-submission tool from the live/fetch sibling get_dataforseo_business_trustpilot_search_fetch.

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 guidance, no mention of the submit/fetch task-based workflow, and no routing between this tool and its many siblings (the *_search_fetch variant, the *_reviews_submit variant, etc.). An agent must infer the entire submission-then-fetch pattern from the name alone.

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