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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds that results are scoped by the parameters chosen at submit time, but says nothing about pagination, result caps, or task-state behavior (e.g., what happens if the task is still processing).

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 sentences, front-loaded with the capability and followed by the scoping note. Slightly verbose in listing return fields that the output schema already covers, but no wasted filler.

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 the description's extensive list of return fields is largely redundant, while the one thing an agent actually needs — that 'id' is a task id obtained from the corresponding submit call — is left to the schema. Functional but with a misdirected emphasis.

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 coverage is 100% and the single 'id' property is fully documented in the schema, so the baseline is 3. Rather than reinforcing that, the description names app_id/location/language — parameters that do not exist on this tool — which risks mildly misleading the agent about what it must supply.

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?

States a specific verb and resource: retrieves Google Play app review feedback data, and enumerates the returned fields (ratings, review content, reviewer profile, dates). It hints at the task-based relationship by referencing the POST request, which helps distinguish it from the *_reviews_submit sibling, though it never states that relationship outright.

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?

Usage is only implied: the mention of 'the POST request' suggests this is the retrieval half of a submit/fetch pair, and the schema notes the id is valid for 30 days. It never says explicitly 'call this after post_dataforseo_app_google_app_reviews_submit with the returned task id', nor when to prefer it over the sibling fetch/submit tools.

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