Code Simplifier Skill

Simplify and refine code for clarity, consistency, and maintainability.

Usage

/code-simplifier                    # Simplify recently modified files
/code-simplifier path/to/file.ts    # Simplify specific file
/code-simplifier --scope=function   # Focus on function-level simplification

What It Does

1. Analyzes code for unnecessary complexity
2. Identifies opportunities to simplify without changing behavior
3. Applies KISS, DRY, and YAGNI principles
4. Preserves all existing functionality

Simplification Targets

• Redundant code paths
• Over-engineered abstractions
• Unnecessary comments (self-documenting code preferred)
• Complex conditionals that can be flattened
• Verbose patterns that have simpler alternatives

Execution

Use the code-simplifier:code-simplifier subagent:

Task(subagent_type="code-simplifier:code-simplifier", prompt="Review and simplify [target files]")

Examples

Before:

function getData() {
  const result = fetchData();
  if (result !== null && result !== undefined) {
    return result;
  } else {
    return null;
  }
}

After:

function getData() {
  return fetchData() ?? null;
}
