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

Annotations already indicate readOnlyHint=false and destructiveHint=false, but the description adds little beyond stating the toggling action. It does not disclose whether the operation is reversible, what happens to existing public links, or any side effects. The bulk support mention adds minor context but fails to address behavioral details like rate limits or confirmation.

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 extremely concise with two sentences. The first sentence immediately states the main action (toggle public link), and the second adds the bulk support feature. No wasted words.

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 tool has three parameters and no output schema, the description is insufficient. It does not clarify parameter relationships, return values, or error conditions. While the core action is clear, the lack of detail forces the agent to rely on implicit knowledge.

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 for parameter meaning. It only mentions 'notebook_ids for batched execution' but does not explain the crucial 'enable' boolean or the primary 'notebook_id' parameter. This leaves significant ambiguity for an agent.

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 tool toggles the public link of a notebook ('Liga/desliga o link público do notebook'). It also mentions bulk support, distinguishing it from sibling tools like notebooklm_share_add or notebooklm_share_remove which handle specific sharing operations.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, context, or when not to use it, leaving the agent to infer usage from the tool name alone.

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