subscription_app_store_review_screenshots_get_instance

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

No annotations are provided, so the description carries the full behavioral burden, yet it says nothing about safety, auth requirements, rate limits, or what is returned. The only signal is the implicit read-only nature of the HTTP GET verb in the path string, which is minimal disclosure.

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 text is short but wasteful: the identical path appears twice in parentheses, adding no information. It is not front-loaded with any purpose statement an agent could act on.

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?

With no annotations and no output schema, the description should compensate for the missing behavioral and return-value context, but it offers only a bare endpoint. For a 4-parameter resource-fetch tool, this leaves the agent without enough to invoke it confidently beyond the schema.

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 100%, so the four parameters (id, include, fields_subscriptions, fields_subscriptionAppStoreReviewScreenshots) are already documented in the schema. The description adds no meaning beyond the path template's {id}, so baseline 3 applies.

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 is the raw HTTP endpoint 'GET /v1/subscriptionAppStoreReviewScreenshots/{id}', duplicated in parentheses. It restates the tool name rather than stating a purpose in natural language; an agent learns only that this is a read of a single review screenshot by id, which the name already conveys.

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 of prerequisites or permissions, and no routing to alternatives such as the create/update/delete siblings or the related subscriptions endpoint. Nothing tells the agent when this tool is the right choice.

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