search-nodejs-modules-api-documentation

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

No annotations present, so description bears full burden. It does not disclose behavioral traits such as read-only nature, side effects, or any limitations. The description only states priority but omits safety or idempotency information.

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 uses XML-like tags and includes redundant emphasis ('HIGH PRIORITY', underlining). While informative, it could be more concise and structured without the extra formatting.

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 and zero parameters, the description adequately explains the tool's behavior: searching core modules and returning a list. It lacks details on result format or pagination, but for a simple listing tool, it is reasonably complete.

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?

With 0 parameters and 100% schema coverage, the description adds value by explaining the output: 'returns a list of all Node.js core modules and their methods'. This contextualizes the tool's purpose beyond the empty schema.

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 searches Node.js core modules API documentation and returns a list of modules and methods. The verb 'search' and resource 'core modules API documentation' are specific, but the lack of input parameters makes the behavior ambiguous (always returns all). It distinguishes from sibling 'retrieve' but not explicitly.

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?

Explicitly states 'ALWAYS use this tool first' and advises suggesting built-in Node.js API over third-party libraries. This provides strong guidance on when and how to use the tool, with clear priority and exclusion of alternatives.

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