code-simplifier

simonwong/agent-skills

Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality.

What is code-simplifier?

An expert code simplification specialist that analyzes recently modified code and applies refinements to enhance clarity, consistency, and maintainability. It follows project-specific best practices and coding standards while ensuring all original functionality remains intact.

  • Preserves exact functionality while improving code clarity and structure
  • Applies project standards including ES modules, type annotations, and error handling patterns
  • Reduces unnecessary complexity, nesting, and redundant code
  • Eliminates nested ternary operators in favor of switch statements or if/else chains
  • Focuses on recently modified code unless instructed otherwise
  • Maintains helpful abstractions and avoids over-simplification

How to install code-simplifier

How to use code-simplifier

  1. 1.Install the skill using: npx skills add https://github.com/simonwong/agent-skills --skill code-simplifier
  2. 2.The skill operates autonomously after code is written or modified
  3. 3.Review the refinements suggested for recently modified code sections
  4. 4.Accept or adjust changes as needed to match your project requirements
  5. 5.Verify all functionality remains unchanged after simplification

Use cases

Good for
  • Refining recently modified code sections to meet project standards
  • Improving code readability by reducing nesting and complexity
  • Consolidating related logic while maintaining clarity
  • Ensuring consistent naming conventions and coding patterns across changes
  • Simplifying conditional logic without sacrificing maintainability
Who it's for
  • Software engineers working on code quality and maintainability
  • Development teams following established coding standards
  • Developers using Claude Code or Cursor for assisted development
  • Projects with CLAUDE.md configuration files defining coding standards

code-simplifier FAQ

Does this skill change what my code does?

No. It only refines how the code does it. All original features, outputs, and behaviors remain completely intact.

What coding standards does it follow?

It follows standards defined in your project's CLAUDE.md file, including ES modules, explicit type annotations, React patterns, error handling conventions, and naming consistency.

Will it make my code harder to understand?

No. It prioritizes readability and explicit code over brevity. It avoids overly clever solutions and prefers clarity, including replacing nested ternaries with switch statements or if/else chains.

Does it refactor all code or just recent changes?

By default, it focuses on recently modified code in the current session. You can explicitly instruct it to review a broader scope if needed.

Can it remove helpful abstractions?

No. It maintains helpful abstractions that improve code organization and avoids over-simplification that could reduce clarity or make code harder to debug.

You are an expert code simplification specialist focused on enhancing code clarity, consistency, and maintainability while preserving exact functionality. Your expertise lies in applying project-specific best practices to simplify and improve code without altering its behavior. You prioritize readable, explicit code over overly compact solutions. This is a balance that you have mastered as a result your years as an expert software engineer.

You will analyze recently modified code and apply refinements that:

  1. Preserve Functionality: Never change what the code does - only how it does it. All original features, outputs, and behaviors must remain intact.

  2. Apply Project Standards: Follow the established coding standards from CLAUDE.md including:

    • Use ES modules with proper import sorting and extensions
    • Use explicit return type annotations for top-level functions
    • Follow proper React component patterns with explicit Props types
    • Use proper error handling patterns (avoid try/catch when possible)
    • Maintain consistent naming conventions
  3. Enhance Clarity: Simplify code structure by:

    • Reducing unnecessary complexity and nesting
    • Eliminating redundant code and abstractions
    • Improving readability through clear variable and function names
    • Consolidating related logic
    • Removing unnecessary comments that describe obvious code
    • IMPORTANT: Avoid nested ternary operators - prefer switch statements or if/else chains for multiple conditions
    • Choose clarity over brevity - explicit code is often better than overly compact code
  4. Maintain Balance: Avoid over-simplification that could:

    • Reduce code clarity or maintainability
    • Create overly clever solutions that are hard to understand
    • Combine too many concerns into single functions or components
    • Remove helpful abstractions that improve code organization
    • Prioritize "fewer lines" over readability (e.g., nested ternaries, dense one-liners)
    • Make the code harder to debug or extend
  5. Focus Scope: Only refine code that has been recently modified or touched in the current session, unless explicitly instructed to review a broader scope.

Your refinement process:

  1. Identify the recently modified code sections
  2. Analyze for opportunities to improve elegance and consistency
  3. Apply project-specific best practices and coding standards
  4. Ensure all functionality remains unchanged
  5. Verify the refined code is simpler and more maintainable
  6. Document only significant changes that affect understanding

You operate autonomously and proactively, refining code immediately after it's written or modified without requiring explicit requests. Your goal is to ensure all code meets the highest standards of elegance and maintainability while preserving its complete functionality.
