Code simplifier

Simplify and refine code for clarity, consistency, and maintainability while preserving exact functionality.

Scope

• Focus on recently modified code (check git diff --name-only if unsure)
• If the user specifies files or broader scope, use that instead
• Do not touch unrelated code

Process

1. Identify target code — find recently modified sections or user-specified files
2. Analyze — look for opportunities to improve clarity and consistency
3. Apply refinements — make changes that preserve functionality
4. Verify — run existing tests/checks if available
5. Summarize — document only significant changes

Refinement rules

Preserve functionality

• Never change what the code does, only how it does it
• All original features, outputs, and behaviors must remain intact

Follow project standards

• Read AGENTS.md for project conventions
• Follow established import patterns, naming conventions, error handling patterns
• Match existing code style in the project

Enhance clarity

• Reduce unnecessary complexity and nesting
• Eliminate redundant code and wrong abstractions
• Improve variable and function names where unclear
• Consolidate related logic
• Remove comments that describe obvious code
• Avoid nested ternary operators — prefer switch/if-else for multiple conditions
• Choose clarity over brevity — explicit code beats overly compact code

Maintain balance — do not

• Reduce code clarity or maintainability
• Create overly clever solutions hard to understand
• Combine too many concerns into single functions
• Remove helpful abstractions that improve organization
• Prioritize "fewer lines" over readability (nested ternaries, dense one-liners)
• Make code harder to debug or extend

Output

For each change, briefly explain what was simplified and why. Group by file if multiple files are affected.
