get_audiobook

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

With no annotations provided, the description carries full burden but only states basic purpose. It fails to disclose read-only behavior, authentication needs, error conditions, or return format. For a retrieval tool, this is minimal disclosure.

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 short and front-loaded with the purpose, but includes unnecessary Python docstring formatting ('Args:'). Otherwise efficient, with no filler content.

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?

An output schema exists, so return values are covered elsewhere. However, the description lacks context about optional behavior (e.g., market not required), error handling, or relationship to other tools. Adequate for a simple getter but could be richer.

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 description coverage is 0%, but the description adds meaningful context: 'The Spotify ID of the audiobook' for audiobook_id and 'ISO 3166-1 alpha-2 country code' for market. This compensates for missing schema descriptions and clarifies parameter meaning.

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 'Get details of a Spotify audiobook,' specifying the verb (Get), resource (details), and scope (a single audiobook). This distinguishes it from siblings like get_audiobooks (plural) and get_audiobook_chapters.

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 provides no guidance on when to use this tool versus alternatives, such as get_audiobooks for multiple audiobooks or get_audiobook_chapters for chapters. No context about prerequisites or common use cases.

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