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

With no annotations provided, the description carries full burden for behavioral transparency. It fails to disclose any behavioral traits such as what the tool returns, side effects, permissions needed, or rate limits. The description is merely a label.

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 extremely concise but at the cost of completeness. Every sentence should add value; here, a single phrase repeats the tool's purpose without elaboration, making it under-specified.

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 and lack of output schema, the description should clarify what documentation is retrieved and how to use parameters. It fails to do so, leaving critical gaps in understanding the tool's functionality.

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 includes 'class' and 'method' parameters with descriptions, covering 67% of parameters. The description adds no additional meaning to these parameters, nor does it explain their usage or format, failing to compensate for the incomplete schema coverage.

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 'Node.js API: Cluster' indicates the tool provides API documentation for the Node.js Cluster module, distinguishing it from sibling tools focusing on other modules. However, it lacks a clear verb like 'retrieve' or 'search' and does not specify the action taken.

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 given on when to use this tool versus alternatives. While sibling tools are for different modules, the description offers no context on prerequisites, use cases, or when to choose this specific tool.

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