app_store_versions__get

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds the GET endpoint but no additional behavioral context such as error behavior or rate limits. With annotations covering the core traits, this is adequate but not enriched.

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 description is one concise sentence plus the endpoint, with zero filler. It immediately states the verb and resource, making it highly scannable.

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 simple single-resource GET with full schema coverage and strong annotations, this is essentially complete. It lacks explicit mention of response shape, but the fields parameter enumerates available attributes, and the endpoint convention implies a standard resource object. The tool is slightly less rich than the 'get_calls' exemplar, hence 4 rather than 5.

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%, with id, include, and fields_appStoreVersions all thoroughly described. The description adds no parameter-specific meaning; as expected, the schema carries the load. This meets the baseline for high coverage.

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 'Read' and identifies the resource as 'one App Store version by ID', clearly distinguishing this singular get operation from sibling operations like deletion or list endpoints. The endpoint reference reinforces the exact resource.

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 used when you have a specific version ID to retrieve, but it doesn't explicitly mention when to prefer it over alternatives such as listing versions. The id parameter schema hints that the ID comes from a 'matching list call', but no explicit when/when-not guidance is given in the description itself.

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