app_store_versions__create

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

Annotations already mark this as a non-read-only, non-idempotent, destructive write. The description adds the useful label 'RELEASE-level write' and clarifies it creates rather than deletes, which prevents misinterpretation. Still, it doesn't disclose additional behavioral traits like duplication risks or state after creation, but the annotation lowers the burden.

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 compact and front-loaded: it states the purpose in the first sentence, then gives the workflow ordering, then the endpoint and level. Every sentence adds value with no filler or repetition.

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 nested schema and the workflow context in the description, an agent has enough to select and invoke the tool. The end-to-end sequence (create → attach build → submit) is clearly laid out. It lacks output/response expectations, but no output schema exists and the create action's outcome is implicit.

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 only parameter 'body' has a schema description, giving 100% schema coverage, so the baseline is 3. The tool description does not add parameter-level guidance beyond 'create a new App Store version', but the nested schema clearly documents required attributes and relationships. No extra semantic value is provided by the description.

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: 'create a new App Store version to prepare' with an explicit resource and verb. It distinguishes this from siblings like update/delete by framing it as 'Start the next release' and referencing the specific endpoint, making its role unambiguous.

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 gives explicit workflow context: 'Do this before attaching a build and submitting for review.' This tells an agent when in the release process to use the tool. However, it does not name alternatives or state when not to use it, so it stops short of a 5.

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