The two tools have clearly distinct purposes: one searches across all Node.js modules to find relevant documentation, and the other retrieves detailed documentation for a specific module or class. There is no overlap or ambiguity.

Both tools follow a consistent snake_case pattern with a verb prefix ('search-' and 'retrieve-') followed by the domain ('nodejs-modules-api-documentation'). The structure is uniform and predictable.

With only two tools, the set is minimal but covers the core workflow of searching and retrieving documentation. However, for a domain as broad as all Node.js core modules, a few more tools (e.g., listing all modules without a search) might improve completeness.

The search tool effectively serves as both a search and listing function, returning all modules and their methods. The retrieve tool provides detailed documentation for a specific module. Together, they cover the essential documentation needs, but there is no explicit tool for browsing modules by category or method signatures.
