apps__app_store_versions__list

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

Annotations already declare readOnly, idempotent, and non-destructive behavior, so the description's burden is low. It adds that the response includes review state, but this is also present in the schema's fields/filter options. No extra behavioral details like pagination behavior beyond the schema.

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?

One concise sentence that front-loads the action and includes the endpoint for reference. No redundant information.

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 list tool with rich annotations and schema, the description is minimally adequate. It lacks usage alternatives and pagination specifics, but the schema covers parameters and the endpoint is clear. Given no output schema, it could mention the return type, but review state is highlighted.

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?

The schema has 100% description coverage for all 10 parameters, so the description does not need to add parameter semantics. The endpoint reference reinforces the required 'id' parameter, but overall the description adds minimal value beyond schema.

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 uses the specific verb 'List', identifies the resource 'App Store versions', and scopes it to 'for an app'. It also provides examples of the review state included, distinguishing it from related list tools.

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?

The description implies the tool is for retrieving versions for a specific app and mentions the endpoint pattern, but it does not explicitly state when to use this vs alternatives or mention exclusions. No sibling differentiation is provided.

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