notebook_rename

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

With no annotations, the description carries the full behavioral burden. It usefully discloses an RPC bridge and a conditional config-file update side effect, but it does not state required permissions, what happens when no notebook is attached, or whether the operation is reversible.

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 a single front-loaded sentence with no filler. Every clause contributes: the action, the target, the bridge, and the conditional side effect.

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?

For a mutation tool with no annotations and 0% schema description coverage, one sentence is insufficiently complete. It omits parameter semantics, attachment prerequisites, and failure behavior; the output schema covers return values, but the call-side guidance remains thin.

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 description coverage is 0%, and the description names none of the three parameters. It does not explain the required 'new_title', the optional 'notebook_id', or the role of 'workspace_dir', leaving the agent with no parameter meaning beyond what the schema titles weakly imply.

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 states a specific verb ('Rename') and resource ('Gemini Notebook'), and adds the mechanism ('via the RPC bridge') plus a conditional side effect. It is clearly distinct from create/delete/attach siblings, though it does not explicitly compare itself to alternatives.

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?

There is no guidance on when to use this tool versus alternatives such as notebook_attach or notebook_create, and no prerequisites are stated beyond the conditional '.agents/notebook.json' note. The agent must infer usage conditions from the name.

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