notebooklm_create_notebook

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

With no annotations, the description carries the full burden, but it only restates the creation action. It discloses no return value, created-notebook identifier, persistence behavior, idempotency, or authorization requirements.

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 five-word sentence with no filler or redundant phrasing. It is maximally concise and front-loads the tool's purpose.

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?

Despite complete parameter schema coverage, the tool has no annotations and no output schema, so the agent is left without information about what the create operation returns or what side effects to expect. The description alone is too thin for a mutating operation.

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 input schema already describes both parameters (`title` and `description`) with 100% coverage, so the description does not need to add parameter semantics. It adds nothing beyond the schema, matching the baseline.

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 the operation ('Create') and the resource ('a new notebook'`), so an agent can tell what the tool does. It does not explicitly name or contrast sibling tools, but the action is unambiguous among the sibling set.

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 given for when to use this tool versus siblings like notebooklm_list_notebooks, notebooklm_get_notebook, or notebooklm_share_notebook. The intended usage is only implied by the verb 'Create', with no prerequisites, exclusions, or alternatves.

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