get_wishlist

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

With no annotations, the description carries the full burden of behavioral disclosure. It correctly indicates a read-only list operation, but it does not mention what fields are returned, whether pagination is involved, authentication requirements, or how this response differs from get_library. The behavioral information is minimal but not misleading.

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?

A single sentence with no filler. The verb and resource are front-loaded, and every word earns its place. Excellent conciseness.

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?

For a parameterless list tool with no output schema, the description covers the essential action and scope. The 'wishlist' qualifier helps differentiate it from get_library. It omits return-format details, but given the tool's simplicity, nothing critical is missing for an agent to invoke it.

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 tool has zero parameters, so the schema is fully covered (100%) and there is nothing for the description to add. The baseline of 4 applies because no parameter meaning needs to be explained.

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?

States the verb 'List' and the specific resource 'audiobooks in the user's Audible wishlist.' This clearly distinguishes it from siblings such as search_audiobooks (catalog search), get_library (the user's library, not wishlist), and add_to_wishlist (a write operation). No ambiguity about what the tool does.

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 implies usage whenever the user's wishlist needs to be retrieved, but it gives no explicit when/when-not guidance or alternatives. An agent might struggle to differentiate between get_wishlist and get_library, since both return collections of audiobooks; the description offers no comparative context.

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