get_api_for-worker_threads

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

No annotations exist, and the description provides no behavioral information such as side effects, authentication requirements, rate limits, or what the tool does beyond identifying its topic. This is a significant gap.

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 concise at one short phrase, but it sacrifices necessary detail. It is not well-structured for an AI agent to understand the tool's purpose and usage.

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 (optional parameters, no output schema), the description should at least state what result is returned. Currently it only labels the topic area, leaving the agent guessing about output and use cases.

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 description adds no meaning beyond the input schema. While the schema explains 'class' and 'method' parameters, the description fails to clarify their roles or how they interact. The lack of parameter context is especially problematic with 67% 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: Worker threads' conveys the resource type but lacks a specific action verb. The tool name includes 'get_api', which implies retrieval, but the description does not reinforce this or distinguish it from siblings that follow the same pattern.

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 guidance is provided. The description does not indicate when to use this tool versus other 'get_api_for-*' tools or the sibling 'search-nodejs-modules-api-documentation', leaving the agent without decision context.

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