Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 1660, "days_push": 720, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated catalog of Elixir-specific code smells documenting sub-optimal code patterns unique to the Elixir language, organized into design-related and low-level concern categories. It serves as an educational reference with runnable Livebook examples for improving code quality in Elixir projects.

## Use cases
- identify code smells in my elixir codebase
- learn common elixir anti-patterns
- refactor genserver-heavy elixir code
- study elixir software quality patterns
- find examples of bad elixir design
- teach code review guidelines for elixir

## When to choose
- you write or review Elixir code and want language-specific quality guidance
- you are learning Elixir idioms and common pitfalls
- you need a reference for code review or refactoring discussions in Elixir teams

## When to avoid
- you need automated linting or static analysis rather than a manual reference catalog
- you work in a language other than Elixir
- you need general-purpose code smell guidance not tied to Elixir

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, linter, developer-tools
- domain: programming-languages, developer-tools, tutorials
- platform: elixir, cross-platform
- tags: code-smells, elixir, software-quality, refactoring, catalog, functional-programming, algorithms
