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

Annotations declare readOnlyHint=false, destructiveHint=true, openWorldHint=true and idempotentHint=false, but the description says only that the endpoint 'will provide you with information', which reads like a passive read and omits that it enqueues a billable task (priority 2 costs extra), that it is non-idempotent, and that results arrive via postback/pingback. The framing is directionally misleading, though not a strict reversal of the 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 a single short sentence, so there is no padding to trim, but brevity here comes at the cost of accuracy - the one sentence that exists describes the wrong operation type for a task-submission tool.

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 non-idempotent, destructive-flagged, credit-consuming async submission tool with a sibling fetch endpoint whose existence is essential to using it, the description is far too thin. It says nothing about the task lifecycle, the fetch step, cost implications, or callback URLs, leaving the agent unprepared to call it correctly in a workflow.

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?

Only the single top-level 'body' parameter is measured (0% coverage in context signals), and the description only mentions app_id, ignoring the required location_name/location_code and language_name/language_code pairs. However, the nested body properties are documented in extensive detail inside the schema itself, so the description's failure to repeat them is a partial gap rather than a fatal one.

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 names a verb ('provide') and resource ('information about the App Store application'), so the domain is identifiable, but it never states that this is a task-creation endpoint despite the name ending in '_submit' and the title saying 'Setting ... Tasks'. It also gives no differentiation from the sibling get_dataforseo_app_apple_app_info_fetch, which returns the actual results of the task this tool creates.

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 that this is an asynchronous task submission that must be paired with get_dataforseo_app_apple_app_info_fetch, and no exclusion relative to post_dataforseo_app_google_app_info_submit. The agent is left to infer the entire workflow 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.
