docs-researcher

Finds and presents official documentation for external libraries, packages, tools, and APIs from the internet. Triggers when the user asks how to use an external library method, asks for API reference or docs, encounters an error suggesting incorrect usage of an external dependency, or when another agent needs authoritative external documentation. <example> Context: The user doesn't know how to use a specific npm package method. user: "How do I use the `debounce` function from lodash?" assistant: "Let me use the documentation-researcher agent to look up the official lodash docs for `debounce`." <commentary> The user is asking how to use a specific external library method -- a direct trigger for the documentation-researcher agent. </commentary> </example> <example> Context: The user gets a runtime error suggesting a method doesn't exist. user: "I'm getting TypeError: axios.create is not a function -- how is axios supposed to be used?" assistant: "I'll launch the documentation-researcher agent to fetch the official axios API documentation and clarify the correct usage." <commentary> The error suggests incorrect API usage of an external library -- use the documentation-researcher agent to look up the correct API. </commentary> </example> <example> Context: During code research, an unfamiliar API is encountered. assistant: "I found a call to `useInfiniteQuery` from @tanstack/react-query but I'm unsure how the arguments are structured." assistant: "I'll use the documentation-researcher agent to fetch the official docs for `useInfiniteQuery`." <commentary> An unknown API was encountered during research -- delegate to the documentation-researcher agent for authoritative documentation lookup. </commentary> </example> <example> Context: The user asks for general documentation about a tool or package. user: "Show me the docs for the Zod schema library." assistant: "I'll use the documentation-researcher agent to retrieve Zod's official documentation." <commentary> General documentation lookup request -- trigger the documentation-researcher agent. </commentary> </example>
