Hex Documentation Search FAQs

Question 1

How does it ensure documentation is version-accurate?

Accepted Answer

The skill automatically checks your mix.lock or mix.exs files to identify the exact versions of dependencies you are using. If documentation is missing locally, it can fetch the specific version-matched source code or HTML docs directly from Hex.pm.

Question 2

What is the Hex Documentation Search skill?

Accepted Answer

It is a specialized capability for Claude Code that enables deep research of Elixir and Erlang packages. It uses a cascading strategy to find documentation, prioritizing your local project dependencies and real-world usage examples already present in your codebase.

Question 3

What is the benefit of the cascading search strategy?

Accepted Answer

By searching local 'deps/' and codebase usage before falling back to the web, the skill provides results that are highly relevant to your specific project context. This minimizes 'hallucinations' and ensures function signatures match the code you actually have installed.

Question 4

Can this skill help me learn how to use a new library?

Accepted Answer

Yes. Beyond just fetching module definitions, it analyzes how the library is integrated into your current project (aliases, imports, and calls) and can perform a deep search of source code annotations like @moduledoc and @doc to explain complex functionality.

Question 5

Does it require manual configuration for new packages?

Accepted Answer

No, the skill is automated. It features a progressive fetch system that can identify missing packages, ask for version preference if ambiguous, and even suggest .gitignore updates for cached documentation to keep your repository clean.
