subscription_app_store_review_screenshots_create_instance

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

With no annotations, the description carries the full behavioral burden, yet it only implies mutation via 'POST'. It does not state authentication requirements, that it creates a new resource, whether the body must include a relationship to a subscription, or any side effects.

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?

It is short and front-loaded, but wasteful: the same POST path appears twice in a row (once bare, once in parentheses), and the only substantive content is a schema pointer that the schema already contains.

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 create tool with a nested JSON:API body and no output schema, the definition is incomplete. It omits what resource is being created, what the body must contain beyond a schema name, and any lifecycle or relationship context an agent needs to call it correctly.

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?

There is a single required body parameter with 100% schema description coverage, so the baseline is 3. The description's pointer to components.schemas.SubscriptionAppStoreReviewScreenshotCreateRequest duplicates the schema's own description text rather than adding meaning about envelope structure or required fields.

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 restates the HTTP method and path (POST /v1/subscriptionAppStoreReviewScreenshots) which is effectively the tool name rendered as a URL. It never explains in human terms what a subscription App Store review screenshot is or what creating one accomplishes, so it is close to a tautology.

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 (e.g. an existing subscription to attach the screenshot to), and no differentiation from sibling create tools such as in_app_purchase_app_store_review_screenshots_create_instance or subscription_images_create_instance.

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