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

Annotations already declare readOnly/idempotent/openWorld/non-destructive, so the safety profile is covered; beyond that the description adds genuine behavioral context — that results reflect the search state at task-setting time, that personalization/search history is ignored, and that check_url can be used to independently verify fidelity. It does not, however, state the 30-day retrieval window or pagination/result-size behavior.

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?

Three sentences are spent entirely on output provenance and verification, which is largely wasted because an output schema already exists. Nothing is front-loaded — the reader never learns the tool's action or its prerequisite, so the content is misallocated rather than tight.

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?

Because an output schema exists, return-value explanation is unnecessary and the description's budget should have gone to the essentials: that this is the result-retrieval half of a submit/fetch pair and that the id comes from the submit call. Those critical usage facts are missing, leaving the definition incomplete for an agent deciding between it and its many siblings.

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 one parameter at 100% schema description coverage, the schema fully documents the UUID task identifier and its 30-day usability, so the baseline is 3. The description adds no meaning about the id beyond the vague phrase 'at the time of task setting'.

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 a retrieval verb: it describes what the returned results are scoped to (establishment, search engine, location, language) without saying the tool fetches the stored result of a previously submitted task. Only the tool name/title ('Get ... Results by id') conveys the action, and nothing distinguishes it from sibling fetchers like get_dataforseo_business_google_extended_reviews_fetch or get_dataforseo_business_tripadvisor_reviews_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?

There is no when-to-use or when-not-to-use guidance and no mention of the prerequisite that a task must first be created via post_dataforseo_business_google_reviews_submit. The only actionable hint ('accessing the check_url') is about verifying output, not about choosing this tool.

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