Update App Store Version

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

Annotations already indicate non-read-only, non-destructive, idempotent behavior. The description adds that the tool can change release behavior (manual/automatic/scheduled), but does not elaborate on side effects or required permissions, leaving gaps beyond 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 12-word sentence, making it very concise but at the cost of omitting critical details. While front-loaded, it is too minimal to serve the agent effectively.

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 7 parameters, no output schema, and 0% schema coverage, the description is severely inadequate. It lacks details about required parameters (versionId), return values, and prerequisites for fields like earliestReleaseDate.

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?

With 0% schema coverage and 7 parameters, the description provides no explanations for individual fields. It only generically mentions 'metadata' and 'release behavior,' failing to clarify what each parameter does (e.g., usesIdfa, copyright, downloadable).

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') and the resource ('version metadata and choose... release behavior'), specifying exact capabilities. It distinguishes from sibling tools like asc_update_version_localization by focusing on the version's metadata and release type.

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?

No guidance on when to use this tool vs. alternatives (e.g., asc_release_app_store_version, asc_submit_app_store_version). The description does not mention prerequisites, constraints, or when not to use it.

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