Can I search for functions without knowing their names?

Yes, you can search using type signatures like '(a -> Bool) -> [a] -> [a]' to find functions that match that specific transformation logic.

Can I limit searches to a specific Haskell package?

Yes, you can use package filters by adding '+packagename' to your query, which narrows the results to only those exported by that specific library.

Hoogle is a specialized search engine for the Haskell programming language that allows users to find functions by their names or, uniquely, by their type signatures.

How do I see the full documentation for a search result?

You can append the --info flag to your search command to retrieve the detailed documentation and package information for the top search result.

Does this skill require an internet connection?

While it can query online sources, the skill includes a database initialization script that can build a local database from Stackage or project docs for offline use.

Aprendizaje y Documentación

Searches Haskell APIs by function name or type signature to streamline functional programming workflows.

Hoogle API Search integrates the powerful Hoogle engine directly into Claude, enabling developers to quickly find Haskell functions, verify type signatures, and explore library documentation without leaving their terminal. This skill is indispensable for Haskell development, allowing for proactive API discovery and the ability to find specific functions based on their type logic (e.g., 'a -> b -> a'). By providing immediate access to Hackage documentation and module export information, it significantly reduces context-switching and accelerates the implementation of complex functional patterns.
