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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, indicating a safe read operation. The description adds information about batch execution, which is useful behavioral context beyond annotations, but does not cover response format or other behaviors.

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 very short with two sentences, no fluff. However, the first sentence is nearly redundant with the tool name. Still, it is efficiently structured and front-loaded.

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 lack of output schema and 0% schema coverage for 4 parameters, the description is incomplete. It does not explain return values, parameter details (e.g., format of IDs), batch size limits, or error handling. The tool is simple but the description insufficiently compensates for missing schema.

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 coverage is 0%, so the description must compensate. It mentions notebook_ids and note_ids for batch execution, giving meaning to the array parameters, but does not explain the relationship between singular and plural parameters, required fields, or how batch interacts with required 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 clearly states 'Conteúdo de uma nota' (content of a note) and the name 'note_get' indicates retrieval. It distinguishes from sibling tools like note_list (which lists summaries) and note_create/delete/rename. The bulk support mention further clarifies the scope.

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 mentions bulk support via notebook_ids and note_ids, but does not provide explicit guidance on when to use this tool vs alternatives like notebooklm_note_list. No context on prerequisites or exclusions.

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