notebook_create

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

No annotations are provided, so the description carries the full behavioral burden for a mutation tool. It does not state required permissions, what 'attach' does to the workspace, whether the title must be unique, how 'engine' selection behaves, or what side effects occur. The API/RPC mention is implementation detail rather than behavioral disclosure.

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?

A single front-loaded sentence with no repetition. The 'via GCP v1alpha REST API or RPC bridge' clause is somewhat implementation-heavy and does not help an agent decide or invoke, but the overall statement remains tight.

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 six-parameter mutation tool with no annotations and 0% schema coverage, this description is too thin. The output schema means return values need not be explained, but missing details about prerequisites, engine selection, workspace attachment, and parameter behavior leave significant gaps.

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% across six parameters, so the description must compensate. It only loosely hints at attach_to_workspace with 'optionally attach it' and says nothing about title, alias, emoji, engine (including valid values beyond the default 'auto'), or workspace_dir. Most parameter meaning is left undocumented.

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?

States a specific verb and resource: 'Create a new Gemini Notebook.' The mention of GCP v1alpha REST API or RPC bridge adds implementation context, and 'optionally attach it' hints at a post-create step. It doesn't explicitly contrast with siblings like notebook_attach or notebook_list, but the create action 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?

There is no guidance on when to use this versus notebook_attach, notebook_list, or whether the workspace must already exist. The phrase 'optionally attach it' implies a workflow choice but does not explain the condition or prerequisites such as authentication or an existing workspace.

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