app_store_versions__create

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

Annotations already indicate it's a write operation (readOnlyHint false). The description adds a creation hint but no further behavioral details (e.g., side effects, permissions). No contradiction with annotations, but limited added value.

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?

Two concise sentences: first sentence states the core action, second provides a crucial workflow step. No extraneous information, front-loaded with primary purpose. Highly efficient.

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 nested schema (required attributes, relationships) and no output schema, a more detailed description of what the response contains or validation rules would help. The workflow hint partially compensates, but completeness is adequate rather than excellent.

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% (body parameter has description 'JSON:API request body...'). The tool description does not elaborate on parameters beyond the operation itself. Baseline 3 is appropriate since the schema already documents the required structure.

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?

Clearly states 'Create a new App Store version' with a specific verb and resource. The workflow hint 'Do this before attaching a build and submitting for review' distinguishes it from update/delete siblings, making the purpose 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?

Provides explicit workflow context: 'Do this before attaching a build and submitting for review.' This implicitly tells when to use (before build attachment) but does not explicitly exclude alternatives like update or list. No 'when not to use' stated.

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