list_notebooks

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

No annotations are provided, so the description carries full burden. It states the tool lists all notebooks with their ids, which is accurate and non-destructive. However, it does not disclose any behavioral traits such as pagination, ordering, or rate limits. For a zero-parameter tool, the description is minimal but adequate.

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 that conveys the essential purpose and a hint of usage. No wasted words—every part contributes value.

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 (no parameters, output schema exists) and the presence of sibling tools, the description is sufficient. It could optionally mention that notebooks are hierarchical, but the output schema likely covers return fields. Overall, it is complete enough for the tool's complexity.

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 zero parameters with 100% coverage via description (the schema itself is empty). There is no need for additional parameter semantics. The baseline for no parameters is 4, and the description does not need to add more.

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 it lists all Joplin notebooks with their ids, providing the specific verb 'list' and resource 'notebooks'. It also hints at a primary use case (for create_note). Among sibling tools, no other tool lists notebooks, so it is well-distinguished.

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?

The description mentions a use case ('for use with create_note'), giving context on when to use it. However, it does not explicitly state when not to use it or compare to alternatives like search_notes or list_notes_in_notebook. The guidance is clear but could be more complete.

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