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

Annotations already cover the safety profile (readOnly, idempotent, openWorld, non-destructive), and the description adds genuine extra context: results emulate the specified location/search engine with high fidelity and ignore personalized factors. It also points to check_url for independent verification, which is useful behavioral detail. It omits retrieval timing/completeness state, so not a 5.

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?

The prose is padded and not front-loaded: it opens with result-provenance detail rather than what the tool does. The pricing boilerplate and Incognito-mode aside add length without helping invocation.

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 needn't be explained, and the description adequately characterizes result semantics. However, for a task-result fetch it omits the flow context (id origin, availability window beyond the schema note) that an agent needs to call it at the right time.

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 at 100% schema coverage, the schema fully documents the id. The description references 'establishment name, search engine, location and language parameters,' which are not this tool's inputs and risk confusing the agent about what it must supply (only id). Baseline 3 applies since the schema does the heavy lifting.

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 name and title indicate fetching Google reviews results by id, but the description never states the core action (retrieving results of a previously submitted task). Instead it leads with how the returned data was generated, leaving the verb+resource implicit. It also does not distinguish this fetch tool from siblings like get_dataforseo_business_google_extended_reviews_fetch or the submit counterpart.

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 is given: it never says the id must come from post_dataforseo_business_google_reviews_submit nor that results are only available after task completion. The only actionable instruction is to verify via check_url in Incognito mode, which is a verification tip rather than usage routing.

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