app_store_versions_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 discloses nothing: no auth/scope requirements, no note that this is a safe read, no hint that include/fields parameters expand or trim the payload. A bare HTTP verb and path is not behavioral 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?

It is short, but the string 'GET /v1/appStoreVersions/{id}' is printed twice in a redundant parenthetical, which is pure noise rather than useful brevity.

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 resource with 17 parameters covering relationship inclusion and sparse fieldsets, no output schema, and no annotations, the description should at minimum explain the include/fields semantics and the read-only nature. It explains none of this.

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% across all 17 parameters, so the schema already documents id, include, and the many fields_* / limit_* options. With coverage this high and no parameter commentary in the description, the baseline of 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 tool name restated in REST form: 'GET /v1/appStoreVersions/{id}'. It conveys only that a single appStoreVersion is fetched by id, adding nothing beyond the name, and does nothing to separate it from siblings like app_store_versions_update_instance or app_store_versions_delete_instance.

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 alternatives. An agent cannot tell from the description why it would call this rather than app_store_versions_alternative_distribution_package_get_to_one_related or a list endpoint.

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