notebooklm_generate_audio

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Generate audio overview,' omitting important traits such as whether generation is asynchronous, whether pre-existing sources are required, or what resource is created. There is no contradiction with annotations because none exist.

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 a single sentence with no wasted words and front-loads the core action. It is efficient, though its brevity comes at the cost of behavioral and contextual detail.

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 absence of annotations and output schema, the description is not complete enough. It fails to mention the customization options available, any asynchronous or long-running behavior, or what the result of generation looks like, leaving an agent with insufficient context for confident invocation.

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 effectively complete: notebookId, sourceIds, episodeFocus, and languageCode all have descriptions. The description itself adds no parameter-level meaning, so it stays at the baseline for schema-covered parameters.

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 states a specific verb and resource: 'Generate audio overview for a notebook.' This clearly distinguishes it from sibling tools like deleting audio or managing sources. It is less than a 5 because it does not elaborate on what an 'audio overview' is or explicitly contrast itself with any sibling.

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 is provided on when to use this tool versus alternatives, nor on prerequisites such as the notebook needing to exist or contain sources. The description simply states the action without any contextual or exclusionary information.

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