## What it is
Credo is a static code analysis tool for the Elixir language with a focus on code consistency and teaching. It highlights refactoring opportunities, complexity, common mistakes, naming inconsistencies, and helps enforce a desired coding style.

## Use cases
- lint elixir code for style and consistency
- find refactoring opportunities in my elixir project
- detect complex code fragments in elixir
- enforce a coding style across an elixir codebase
- run static analysis in CI for elixir
- warn about common elixir mistakes

## When to choose
- you maintain an Elixir codebase and want consistent, readable code
- you want editor or CI integration for Elixir linting
- you want a linter that explains issues and teaches best practices

## When to avoid
- your project is not written in Elixir
- you need dynamic/runtime bug detection rather than static analysis
- you need type checking (use Dialyzer instead)

## Facets
- artifact type: cli-tool
- maturity: stable
- function: linter, static-site-generator, developer-tools
- domain: developer-tools, programming-languages, testing
- platform: cli, cross-platform
- tags: elixir, static-analysis, code-consistency, code-review, mix
