notebooklm_create_notebook

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

The description says the tool 'Crea un nuevo cuaderno' (a mutation), yet the annotations declare readOnlyHint=true. This is a direct contradiction that could mislead an agent about the tool's side effects. The annotation profile (openWorldHint=true, destructiveHint=false) is also not elaborated on in the text.

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 front-loaded sentence with the creation verb first, followed by the return values. No filler, no redundancy, nothing to trim.

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 simple one-parameter tool with full schema coverage and no output schema, the description is nearly complete: it identifies the created artifact and the values returned (URL, notebook_id). It omits only authentication/ownership context, which for a Google NotebookLM operation would be useful but is not strictly required to invoke the tool.

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?

There is one parameter ('title') with 100% schema description coverage, so the schema already documents it fully. The description adds no additional meaning about the title parameter; it only mentions the returned values (URL, notebook_id), which is output rather than input semantics. Baseline 3 applies.

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: 'Crea un nuevo cuaderno de investigación jurídica en Google NotebookLM'. This is clearly distinguishable from sibling tools like notebooklm_list_notebooks, notebooklm_add_source and notebooklm_query, though it does not explicitly name them.

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?

There is no guidance on when to use this tool versus the sibling notebooklm tools, no prerequisites (e.g., authentication with a Google account), and no mention of what happens on failure or duplicates. The agent must infer usage entirely from the verb.

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