app_store_review_attachments__update

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

Annotations are present but description adds no behavioral context beyond them. Does not disclose what happens during update (e.g., field replacement, upload requirements) or any side effects.

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?

Very concise—one sentence plus the path. Front-loaded with purpose. Minimal waste.

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?

No output schema, and description does not explain return values or behavior. Lacks context on how the update affects the attachment and how to use optional fields. Incomplete for a mutation tool with nested objects.

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%, so parameters are documented. The description adds mention of 'JSON:API request body (Apple schema)' but does not explain the meaning of optional attributes (uploaded, sourceFileChecksum). Baseline score is appropriate.

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 it updates an App Store review attachment and includes the HTTP method and path. The verb 'update' and resource are specific. However, it does not distinguish from sibling tools like create or delete.

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 versus alternatives. It only states the update action without context or exclusions.

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