apple_books_audiobook_reviews

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

With no annotations provided, the description carries the full burden. It usefully discloses the pagination mechanism (catalog page for first page, Apple review API for deeper pages, up to 20 per page), but does not describe the return shape, error behavior, or any rate-limiting considerations.

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 two sentences, front-loaded with the primary action, and every sentence adds value. There is no redundancy or filler.

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?

The tool is a focused reviews retrieval endpoint with a well-documented schema. The description covers the core behavior and pagination nuances; what's missing (return fields, sorting) is not explicitly required given the simplicity and existing schema coverage.

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 baseline is 3. The description adds meaningful semantics beyond the schema by explaining that page >1 or larger limits route through Apple's review API and that the max is 20 per page, which helps the agent understand parameter interactions.

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 uses a specific verb ('Retrieve') and clear resource ('Apple Books audiobook customer reviews'), stating it returns a page of reviews. It distinctly focuses on audiobook reviews, separating it from related siblings like apple_books_book_reviews or apple_books_audiobook_search.

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?

Clear context is provided: this tool is for retrieving audiobook reviews, with pagination details explaining how pages beyond the first are fetched. However, it does not explicitly mention when to prefer this over alternatives like apple_books_audiobook_similar or apple_books_book_reviews.

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