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

Annotations indicate readOnlyHint false and destructiveHint false, consistent with renaming. The description adds bulk execution behavior. No contradictions, but no further disclosure of side effects or permission 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?

Two sentences, no extraneous content. The first sentence states the purpose, the second adds bulk information. Efficient, but could benefit from slightly more structure, e.g., separating single and bulk usage.

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?

No output schema exists, and the description does not mention return values. The bulk support is explained, but parameter relationships are unclear. For a tool with 5 parameters and batch capabilities, more details on usage scenarios and parameter combinations would enhance completeness.

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 description must compensate. It explains that note_ids and notebook_ids are for batched execution, but does not clarify the relationship between required single fields (notebook_id, note_id) and optional array fields, nor the meaning of new_title. The parameter interplay remains ambiguous.

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?

Description clearly states 'Renomeia uma nota' (renames a note), identifying the verb and resource. It distinguishes from sibling tools like notebooklm_note_create, notebooklm_note_delete, and notebooklm_note_list by focusing on renaming and adding bulk support.

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?

Description mentions bulk support via arrays for notebook_ids and note_ids, giving some context on when to use bulk vs single. However, it does not specify prerequisites or when to avoid the tool, nor does it mention alternatives. More guidance on required vs optional parameters for bulk usage would improve clarity.

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