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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action ('Get a notebook') without detailing aspects like read-only nature, error handling (e.g., if the ID is invalid), authentication requirements, rate limits, or response format. This is insufficient for a tool with zero annotation coverage.

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, direct sentence with no wasted words. It is front-loaded with the core action ('Get a notebook') and efficiently specifies the method ('using the specified notebook ID'), making it easy to parse quickly.

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's simplicity (0 parameters, no output schema, no annotations), the description is minimal but inadequate. It does not explain what 'get' returns (e.g., notebook details, content, or status), potential errors, or how it differs from similar tools, leaving gaps for an agent to understand full usage context.

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?

The input schema has 0 parameters with 100% description coverage, so no parameters need documentation. The description mentions 'using the specified notebook ID,' which implies an input, but since the schema shows no properties, this could be confusing. However, with zero parameters, the baseline is high as the schema fully covers the lack of inputs.

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 the tool's purpose as 'Get a notebook using the specified notebook ID,' which clearly indicates a retrieval action on a notebook resource. However, it lacks specificity about what 'get' entails (e.g., fetch metadata, content, or both) and does not differentiate from sibling tools like 'get_notebooks' (plural) or 'notebooks_get' (alternative naming), leaving ambiguity in scope.

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 (e.g., needing a notebook ID), exclusions, or comparisons to sibling tools such as 'get_notebooks' (likely for listing) or 'notebooks_get' (similar function), leaving the agent without context for selection.

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