app_store_review_attachments_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, and it discloses almost nothing beyond the fact that it is a GET. It does not state authentication/scope requirements, error behavior for a missing or unauthorized id, or whether relationship data requires the include parameter.

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, but the entire content is a parenthetical duplicate of the same path with zero additional information, so half the text is pure waste. Being brief is not the same as being concise when nothing informative is conveyed.

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 single-resource fetch with four parameters, no annotations, and no output schema, the description should at minimum characterize the returned resource or note that include/fields_* control related data. None of that is present, leaving the agent without the context needed to invoke it confidently.

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 schema already documents id, include, and both fields_* parameters; the description adds no syntax or format detail beyond that. Baseline 3 applies when the schema does the heavy lifting and the description contributes nothing extra.

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 only the raw HTTP path restated twice verbatim, so it names a verb (GET) and a resource path but never explains what an app store review attachment is or what retrieving one returns. It offers no differentiation from siblings such as app_store_review_attachments_create_instance or app_store_review_details_app_store_review_attachments_get_to_many_related, which the tool name alone does not resolve.

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 prerequisites, and no mention of any alternative tool. An agent must guess whether this is the correct call versus the collection or relationship endpoints.

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