get_api_for-webassembly_system_interface_wasi

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

No annotations provided, so the description must disclose behavioral traits. It only states the topic, not whether the tool is read-only, what it returns, or if parameters are required. The schema shows all parameters optional, but this is not clarified in the description.

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 very short (one sentence), which is concise but lacks necessary detail. It does not waste words, but it also does not provide sufficient information for effective tool selection.

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 no output schema, no annotations, and minimal description, the tool is incomplete. It does not explain how to use the parameters or what the return value will be, leaving the agent underinformed.

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 coverage is 67%, with class and method having generic descriptions ('The class name to search for' and 'The method name to search for'). The description adds no additional meaning beyond the schema. The third parameter 'required' is unusual and not explained.

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 'Node.js API: WebAssembly System Interface (WASI)', which combines with the name to indicate the tool retrieves API documentation for the WASI module. However, it does not explicitly state the action (e.g., 'get API documentation'), leaving the purpose somewhat vague compared to more explicit siblings.

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 on when to use this tool versus other get_api_for-* siblings or the search tool. The description provides no context for appropriate usage or prerequisites.

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