app_store_versions__update

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=true. The description adds 'RELEASE-level write' as a permission context and names two specific updatable fields, but it does not clarify whether the update is partial (PATCH semantics) or what happens to omitted fields, nor any side effects beyond the annotations.

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 extremely concise: one sentence, an endpoint reference, and a permission tag. Every word is informative and the action is front-loaded, making it easy to parse quickly.

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?

Given the complex body schema and the absence of an output schema, the description is minimal but not wholly inadequate. It conveys the core purpose and permission level, but lacks guidance on how to construct the body for partial updates, which other fields are updatable, and what the response contains. The detailed schema partially compensates, but semantic gaps remain.

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% for the top-level parameters, with id and body having descriptions. The description adds value by highlighting releaseType and earliestReleaseDate as the attributes to update, but the complex nested body structure and other attributes lack semantic explanation in both the schema and the description, so the added meaning is limited.

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 clearly states the action 'Update an App Store version' and specifies two key attributes (release type and earliest release date), which distinguishes it from create/get/delete tools. However, it does not explicitly contrast with similar update tools like app_store_versions__build__set, so it lacks full sibling differentiation.

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 usage for modifying an existing App Store version via the PATCH endpoint, and the id parameter description mentions 'ID from the matching list call.' However, there is no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites beyond the id.

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