Get a Google Play review

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

No annotations exist, so the description carries the full behavioral burden, yet it only implies a read via the verb 'Get'. It says nothing about error behavior for an unknown reviewId, whether the call requires packageName scoping, or how translationLanguage affects the returned content.

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?

A single short sentence, front-loaded with the verb and resource, with no filler. It is efficient but borders on under-specification rather than being genuinely concise.

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 three-parameter tool with zero schema description coverage, no annotations, and no output schema, one sentence is not enough. The agent is not told what packageName does, what translationLanguage does, or what the response contains.

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% across three parameters, and the description only references reviewId. packageName (required, with a regex pattern) and translationLanguage (optional locale format) get no explanation whatsoever, so an agent must guess their purpose from the names alone.

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 (Get) and resource (one review), and the phrase 'one review' implicitly narrows scope versus the sibling list_reviews. It does not name or explicitly contrast with list_reviews, so differentiation is inference-based rather than stated.

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?

'by its Google Play review ID' implies a precondition: the caller must already hold a review ID, which points away from list_reviews for discovery. However, no when-to-use statement, no exclusion, and no mention of the sibling alternative is given.

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