code-simplifier

# Code Simplifier Clean up and simplify code after making changes. ## When to Use Run this skill after completing a feature or fix to ensure the code is clean, readable, and maintainable. ## Simplification Goals ### Reduce Complexity - Break long functions into smaller, focused ones - Reduce nesting depth (max 3 levels) - Simplify complex conditionals - Extract magic numbers to named constants ### Improve Readability - Use descriptive variable and function names - Add clarifying comments for non-obvious logic - Ensure consistent formatting - Remove unnecessary comments ### Apply Pythonic Patterns - Use list/dict/set comprehensions where appropriate - Use `with` statements for resource management - Use `enumerate()` instead of manual indexing - Use `zip()` for parallel iteration - Use f-strings for formatting - Use `pathlib` for file paths ### Clean Up - Remove unused imports - Remove unused variables - Remove commented-out code - Remove redundant code paths - Consolidate duplicate logic ## Workflow 1. **Identify Changed Files** - Focus on files modified in the current session - Or specify files/directories as arguments 2. **Analyze Each File** - Check for simplification opportunities - Prioritize high-impact improvements 3. **Apply Simplifications** - Make incremental changes - Preserve original behavior - Run tests after each change 4. **Format and Lint** - Run `ruff format .` - Run `ruff check --fix .` 5. **Verify** - Run tests: `pytest` - Ensure behavior unchanged ## Arguments Optionally specify files or directories to simplify. Usage: - `/code-simplifier` - Simplify recently changed files - `/code-simplifier src/module.py` - Simplify specific file - `/code-simplifier src/` - Simplify entire directory ## Example Transformations Before: ```python result = [] for i in range(len(items)): if items[i].is_valid == True: result.append(items[i].value) ``` After: ```python result = [item.value for item in items if item.is_valid] ``` Before: ```python if x != None: if y != None: if z != None: process(x, y, z) ``` After: ```python if all(v is not None for v in (x, y, z)): process(x, y, z) ```
