Create Notebook

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. It does well by disclosing the permission prerequisites for each mode ('$root' write entry or blanket write access for root; write access to the target notebook for nesting), which is genuine context beyond the schema. It does not describe the failure or response behavior, but an output schema exists to cover returns.

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?

Three tight sentences, each earning its place, with the core action front-loaded and the parameter guidance following. No filler or restatement of the title.

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 two-parameter creation tool with an output schema already defining returns, the description supplies the missing pieces: mode selection, permission requirements, and a pointer to the discovery tool. Nothing needed to call it correctly is absent.

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%, so the description must compensate. It fully explains parent_id's duality (null → root, string → nested parent) and how to obtain a valid value, though 'title' is left to the obvious-name inference. Strong coverage given the low schema documentation.

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 notebook') and immediately scopes the operation by distinguishing root creation from nested creation. An agent can tell it apart from the sibling create_note and from list_notebooks without opening any schema.

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?

Gives explicit when-to-use guidance for the one ambiguous parameter: omit parent_id for root, set it to nest. It also names the alternative tool (list_notebooks) for finding a parent_id, which is exactly the routing an agent needs.

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