Update app store version

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

Annotations already declare readOnlyHint=false, indicating a write operation. The description adds that it can assign a build or set various fields, which gives some context about the update scope. However, it does not disclose side effects, whether the update is partial, or what the response contains. No contradiction with 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 a single sentence of about 20 words, front-loaded with the verb 'Update', and every word contributes to understanding the tool's purpose. No redundant or vague phrases.

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 rich parameter schema and annotations (readOnlyHint, destructiveHint), the description is adequate for an update tool. It covers the essential fields and actions. However, it does not mention the return value or that updates are partial, which would be helpful for a mutation tool with no output schema.

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 coverage is 100%, and the description merely lists parameter names that are already described in the schema (buildId, versionString, copyright, releaseType, downloadable). It adds no extra semantic meaning or relationships between parameters, so it stays at the baseline of 3.

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 tool updates an App Store version and lists the specific fields that can be modified (build, version string, copyright, release type, downloadable flag). The verb 'update' distinguishes it from create/get, but it does not explicitly differentiate from the sibling tool update-app-store-version-localization, which is a separate 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 provides no guidance on when to use this tool versus alternatives, prerequisites (e.g., existing appStoreVersionId), or context like 'use this after creating a version' or 'for localizations, use update-app-store-version-localization'. It is purely a statement of functionality.

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