Use when reviewing Elixir code for smells, refactoring problematic patterns, or improving code quality.\n---\n\n# Elixir Anti-Patterns Detection and Refactoring\n\nYou are an expert at identifying Elixir anti-patterns and suggesting idiomatic refactorings. Use this knowledge to analyze code, suggest improvements, and help developers write better Elixir.\n\n## Code-Related Anti-Patterns\n\n### 1. Comments Overuse\n**Problem:** Excessive or self-explanatory comments reduce readability rather than enhance it.\n\n**Detection:**\n- Inline comments explaining obvious code\n- Comments for every function line\n- Comments duplicating what code already says clearly\n\n**Refactoring:**\n- Use clear function and variable names instead of explanatory comments\n- Replace inline comments with `@doc` and `@moduledoc` for documentation\n- Use module attributes for configuration values\n\n**Example:**\n```elixir\n# Bad\ndef calculate() do\n  # Get current time\n  now = DateTime.utc_now()\n  # Add 5 minutes\n  DateTime.add(now, 5 * 60, :second)\nend\n\n# Good\n@minutes_to_add 5\n\ndef timestamp_five_minutes_from_now do\n  now = DateTime.utc_now()\n  DateTime.add(now, @minutes_to_add * 60, :second)\nend\n```\n\n### 2. Complex `else` Clauses in `with`\n**Problem:** Flattening all error handling into a single complex `else` block obscures which clause produced which error.\n\n**Detection:**\n- Large `else` blocks with many pattern match clauses\n- Difficulty determining error sources\n- Complex error handling logic in `else`\n\n**Refactoring:**\n- Normalize return types in private functions\n- Handle errors closer to their source\n- Let `with` focus on success paths\n\n**Example:**\n```elixir\n# Bad\ndef read_config(path) do\n  with {:ok, content} <- File.read(path),\n       {:ok, decoded} <- Jason.decode(content) do\n    {:ok, decoded}\n  else\n    {:error, :enoent} -> {:error, :file_not_found}\n    {:error, %Jason.DecodeError{}} -> {:error, :invalid_json}\n    {:error, reason} -> {:error, reason}\n  end\nend\n\n# Good\ndef read_config(path) do\n  with {:ok, content} <- read_file(path),\n       {:ok, config} <- parse_json(content) do\n    {:ok, config}\n  end\nend\n\ndefp read_file(path) do\n  case File.read(path) do\n    {:ok, content} -> {:ok, content}\n    {:error, :enoent} -> {:error, :file_not_found}\n    error -> error\n  end\nend\n\ndefp parse_json(content) do\n  case Jason.decode(content) do\n    {:ok, data} -> {:ok, data}\n    {:error, _} -> {:error, :invalid_json}\n  end\nend\n```\n\n### 3. Complex Extractions in Clauses\n**Problem:** Extracting values across multiple clauses and arguments makes it unclear which variables serve pattern/guard purposes versus function body usage.\n\n**Detection:**\n- Many variable extractions in function heads\n- Mixed guard and body variable usage\n- Unclear variable purposes\n\n**Refactoring:**\n- Extract only pattern/guard-related variables in function signatures\n- Use capture patterns like `%User{age: age} = user`\n- Extract body variables inside the clause\n\n**Example:**\n```elixir\n# Bad\ndef process(%User{age: age, name: name, email: email} = user) when age >= 18 do\n  # Only using name and email in body, not age\n  send_email(email, \"Hello #{name}\")\nend\n\n# Good\ndef process(%User{age: age} = user) when age >= 18 do\n  send_email(user.email, \"Hello #{user.name}\")\nend\n```\n\n### 4. Dynamic Atom Creation\n**Problem:** Atoms aren't garbage-collected and are limited to ~1 million. Uncontrolled dynamic atom creation poses memory and security risks.\n\n**Detection:**\n- `String.to_atom/1` with untrusted input\n- Converting user input directly to atoms\n- Unbounded atom creation in loops\n\n**Refactoring:**\n- Use explicit mappings via pattern-matching\n- Use `String.to_existing_atom/1` with pre-defined atoms\n- Keep strings when atom conversion isn't necessary\n\n**Example:**\n```elixir\n# Bad - Security risk!\ndef set_role(user, role_string) do\n  %{user | role: String.to_atom(role_string)}\nend\n\n# Good\ndef set_role(user, role) when role in [:admin, :editor, :viewer] do\n  %{user | role: role}\nend\n\n# Or with pattern matching\ndef set_role(user, \"admin\"), do: %{user | role: :admin}\ndef set_role(user, \"editor\"), do: %{user | role: :editor}\ndef set_role(user, \"viewer\"), do: %{user | role: :viewer}\ndef set_role(_user, invalid), do: {:error, \"Invalid role: #{invalid}\"}\n```\n\n### 5. Long Parameter List\n**Problem:** Functions with excessive parameters become confusing and error-prone to use.\n\n**Detection:**\n- Functions with 4+ parameters\n- Parameters that are conceptually related\n- Difficult to remember parameter order\n\n**Refactoring:**\n- Group related parameters into maps or structs\n- Use keyword lists for optional parameters\n- Create domain objects\n\n**Example:**\n```elixir\n# Bad\ndef create_loan(user_id, user_name, user_email, book_id, book_title, book_isbn) do\n  # ...\nend\n\n# Good\ndef create_loan(user, book) do\n  # ...\nend\n\n# Or with keyword list for options\ndef create_loan(user, book, opts \\\\ []) do\n  duration = Keyword.get(opts, :duration, 14)\n  renewable = Keyword.get(opts, :renewable, true)\n  # ...\nend\n```\n\n### 6. Namespace Trespassing\n**Problem:** Defining modules outside your library's namespace risks conflicts since the Erlang VM loads only one module instance per name.\n\n**Detection:**\n- Library defining modules in common namespaces (e.g., `Plug.*` when you're not Plug)\n- Modules without library prefix\n- Potential naming conflicts with other libraries\n\n**Refactoring:**\n- Always prefix modules with your library namespace\n- Use clear, unique top-level module names\n\n**Example:**\n```elixir\n# Bad - Library named :plug_auth\ndefmodule Plug.Auth do\n  # This conflicts with the actual Plug library!\nend\n\n# Good\ndefmodule PlugAuth do\n  # ...\nend\n\ndefmodule PlugAuth.Session do\n  # ...\nend\n```\n\n### 7. Non-assertive Map Access\n**Problem:** Using dynamic access (`map[:key]`) for required keys masks missing data, allowing `nil` to propagate instead of failing fast.\n\n**Detection:**\n- `map[:key]` for required/expected keys\n- Nil checks after map access\n- Silent failures from missing keys\n\n**Refactoring:**\n- Use static access (`map.key`) for required keys\n- Pattern-match on struct/map keys\n- Reserve dynamic access for optional fields\n\n**Example:**\n```elixir\n# Bad\ndef distance(point) do\n  x = point[:x]  # Returns nil if :x is missing!\n  y = point[:y]\n  :math.sqrt(x * x + y * y)  # Crashes on nil, but unclear why\nend\n\n# Good\ndef distance(%{x: x, y: y}) do\n  :math.sqrt(x * x + y * y)  # Clear error if keys missing\nend\n\n# Or with structs\ndefmodule Point do\n  defstruct [:x, :y]\nend\n\ndef distance(%Point{x: x, y: y}) do\n  :math.sqrt(x * x + y * y)\nend\n```\n\n### 8. Non-assertive Pattern Matching\n**Problem:** Writing defensive code that returns incorrect values instead of using pattern matching to assert expected structures causes silent failures.\n\n**Detection:**\n- Defensive nil checks instead of pattern matching\n- Functions returning invalid data on unexpected input\n- Avoiding crashes when crashes are appropriate\n\n**Refactoring:**\n- Use pattern matching to assert expected structures\n- Let functions crash on invalid input\n- Trust supervisors to handle failures\n\n**Example:**\n```elixir\n# Bad\ndef parse_query_param(param) do\n  case String.split(param, \"=\") do\n    [key, value] -> {key, value}\n    _ -> {\"\", \"\"}  # Silent failure!\n  end\nend\n\n# Good\ndef parse_query_param(param) do\n  [key, value] = String.split(param, \"=\")\n  {key, value}\nend\n# Crashes with clear error if format is wrong - this is good!\n```\n\n### 9. Non-assertive Truthiness\n**Problem:** Using truthiness operators (`&&`, `||`, `!`) when all operands are boolean is unnecessarily generic and unclear.\n\n**Detection:**\n- `&&`, `||`, `!` with boolean expressions\n- Comparisons like `is_binary(x) && is_integer(y)`\n- Mixing boolean and truthy logic\n\n**Refactoring:**\n- Use `and`, `or`, `not` for boolean-only operations\n- Reserve `&&`, `||`, `!` for truthy/falsy logic\n\n**Example:**\n```elixir\n# Bad\ndef valid_user?(name, age) do\n  is_binary(name) && is_integer(age) && age >= 18\nend\n\n# Good\ndef valid_user?(name, age) do\n  is_binary(name) and is_integer(age) and age >= 18\nend\n\n# Truthy operators are OK for nil/value checks\ndef get_name(user) do\n  user[:name] || \"Anonymous\"\nend\n```\n\n### 10. Structs with 32 Fields or More\n**Problem:** Structs with 32+ fields switch from Erlang's efficient flat-map representation to hash maps, increasing memory usage.\n\n**Detection:**\n- Struct definitions with 32+ fields\n- Large, flat data structures\n- Performance degradation with many fields\n\n**Refactoring:**\n- Nest optional fields into metadata structures\n- Use nested structs for related fields\n- Group frequently-accessed fields separately\n\n**Example:**\n```elixir\n# Bad\ndefmodule User do\n  defstruct [\n    :id, :email, :name, :age, :address, :city, :state, :zip,\n    :phone, :mobile, :fax, :company, :title, :department,\n    :created_at, :updated_at, :last_login, :login_count,\n    :preference1, :preference2, :preference3, :preference4,\n    # ... 15 more fields\n  ]\nend\n\n# Good\ndefmodule User do\n  defstruct [\n    :id,\n    :email,\n    :name,\n    :profile,      # Nested struct\n    :preferences,  # Nested struct\n    :metadata      # Nested struct\n  ]\nend\n\ndefmodule User.Profile do\n  defstruct [:age, :phone, :mobile, :address, :city, :state, :zip]\nend\n\ndefmodule User.Preferences do\n  defstruct [:theme, :notifications, :language]\nend\n```\n\n## Design-Related Anti-Patterns\n\nAlternative return types, boolean obsession, exceptions used for control flow, primitive\nobsession, unrelated multi-clause functions, and using application configuration for libraries:\nsee `references/design-anti-patterns.md`. This split follows upstream's own code/design\ndivision — a real seam, not an arbitrary cut.\n\n## Usage Guidelines\n\nWhen reviewing or writing Elixir code:\n\n1. **Scan for anti-patterns** - Check code against the patterns listed above\n2. **Explain the problem** - Help the developer understand why it's an issue\n3. **Suggest refactoring** - Provide concrete, idiomatic alternatives\n4. **Consider context** - Sometimes anti-patterns are acceptable for specific use cases\n5. **Prioritize** - Focus on high-impact issues first (security, performance, maintainability)\n\n## Key Principles\n\n- **Let it crash** - Use pattern matching to assert expectations; don't write defensive code\n- **Fail fast** - Expose errors early rather than propagating nil or invalid data\n- **Be explicit** - Prefer clear, specific code over clever or terse solutions\n- **Model your domain** - Create types that represent business concepts\n- **Design for clarity** - Code should be obvious to read and maintain\n","tagline":"Identify and refactor Elixir anti-patterns.
