Hackage Documentation Reader FAQs

Question 1

What does the Hackage Documentation Reader skill do?

Accepted Answer

This skill enables Claude Code to query Hackage directly to retrieve Haskell package documentation. It can list versions, explore module hierarchies, and extract specific type signatures, function definitions, and Haddock documentation comments.

Question 2

When should I use this skill?

Accepted Answer

Use this skill whenever you are writing Haskell code and need precise information on library APIs. It is particularly useful for discovering available functions in a module, verifying type signatures, or understanding how to use specific type classes like FromJSON or ToJSON.

Question 3

How does this skill improve my Haskell development workflow?

Accepted Answer

It eliminates the need to manually browse Hackage in a web browser. By providing Claude with direct access to documentation, the AI can generate more accurate code, reduce type errors, and explain complex Haskell libraries with up-to-date information.

Question 4

What filtering capabilities are available?

Accepted Answer

The skill provides fine-grained filtering options. You can choose to see only exported functions, only types, or only type classes. You can also toggle Haddock comments on or off to get either a high-level overview or a deep dive into the documentation.

Question 5

Does this skill require a specific build system?

Accepted Answer

The Hackage Documentation Reader is optimized for Bazel-driven CLI workflows. It uses Bazel to run the underlying `hackage-doc-cli` tool, ensuring that the documentation retrieval is integrated directly into your existing development environment.
