get_api_for-dns

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

The description provides no behavioral information beyond the tool's domain. With no annotations present, the description carries the full burden of disclosing traits such as side effects, permissions, return format, or pagination. It lacks any such details, leaving the agent uninformed about what the tool does when invoked.

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 too short. While brevity is valued, this description is under-specified and provides no substantive information beyond what is already implied by the tool name. It fails to earn its place, as it adds no value for the agent.

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 numerous sibling tools and the lack of annotations or output schema, the description is severely incomplete. It does not explain what kind of results to expect, how to filter by class or method, or how this differs from searching all Node.js documentation. The agent would struggle to use this tool correctly without additional 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 already includes descriptions for both parameters (class and method), giving a schema description coverage of 100% based on inspection. According to the rubric, with high coverage the baseline is 3. The description does not add additional meaning or context for the parameters, so a score of 3 is appropriate.

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: DNS' is essentially a tautology with the tool name 'get_api_for-dns'. It does not state a specific verb or resource beyond what the name implies, making the purpose vague. It fails to clarify that the tool likely returns DNS-related API documentation, and does not distinguish it from sibling tools that also target other Node.js modules.

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 usage guidelines are provided. The description does not mention when to use this tool versus its many siblings (e.g., get_api_for-http, get_api_for-fs) or the sibling 'search-nodejs-modules-api-documentation'. There are no indications of prerequisites, context, or when not to use this tool.

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