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

The description says 'Remove' but annotations show destructiveHint=false, which is inconsistent for a delete operation. The description does not clarify whether the removal is permanent or reversible, nor does it mention required permissions or side effects.

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 only two sentences, front-loaded with the purpose. It is concise, though a bit more detail on parameters could be included without becoming verbose.

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 no output schema and destructiveHint=false annotations, the description should provide more context about what happens after deletion (e.g., if the source is permanently deleted or just disassociated). It also lacks guidance on when to use this vs. other delete tools.

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 add value. It explains that notebook_ids and source_ids support bulk execution, but does not differentiate between the single (source_id, notebook_id) and array parameters, nor explain their format.

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 action (remove a source) and the resource (notebook). However, it does not differentiate this tool from sibling delete tools like notebooklm_notebook_delete or notebooklm_artifact_delete.

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 source_ids, implying when to use array parameters. But it lacks explicit when-to-use, when-not-to-use, or alternatives to other tools.

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