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

Annotations already indicate this is not read-only (readOnlyHint=false), not idempotent, and not destructive. The description adds transparency by revealing bulk support via 'notebook_ids' for batched execution, beyond what annotations provide.

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 concise with two sentences: one for the main purpose and one for bulk support. It is front-loaded and contains no fluff, though a slightly more structured format could improve readability.

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 4 parameters and no output schema, the description should provide more context on parameter usage (e.g., required fields, default behavior) and return value. It only covers bulk support, leaving significant gaps for a creation 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?

With 0% schema description coverage, the description must compensate. It only adds meaning for 'notebook_ids' (bulk support). The other parameters (title, content, notebook_id) are not explained, leaving their semantics unclear beyond their names.

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 'Cria uma nota no notebook' (Creates a note in the notebook), specifying the verb and resource. It also mentions bulk support. While it does not explicitly differentiate from sibling tools like notebooklm_note_rename, the purpose is unambiguous.

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 implies usage for creating notes but provides no explicit guidance on when to use this tool versus alternatives (e.g., notebooklm_note_rename or notebooklm_note_delete). The mention of bulk support offers some context for batched execution but no exclusions.

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