majiayu000 Code Improvement & Cleanup Skill
Systematic improvements with multi-persona expertise and safety validation.
Quick Start
# Quality improvement
/sc:improve src/ --type quality --safe
# Performance optimization
/sc:improve api-endpoints --type performance
# Dead code cleanup
/sc:improve src/ --cleanup --type code --safe
# Import optimization
/sc:improve --cleanup --type imports
Behavioral Flow
- Analyze - Examine codebase for improvement opportunities
- Plan - Choose approach and activate relevant personas
- Execute - Apply systematic improvements
- Validate - Ensure functionality preservation
- Document - Generate improvement summary
Flags
| Flag | Type | Default | Description |
|---|---|---|---|
--type |
string | quality | quality, performance, maintainability, style, code, imports, files, all |
--cleanup |
bool | false | Enable cleanup mode |
--safe |
bool | true | Conservative with safety validation |
--aggressive |
bool | false | Thorough cleanup (use with caution) |
--preview |
bool | false | Show changes without applying |
--interactive |
bool | false | Guided decision mode |
Personas Activated
- architect - Structure and design improvements
- performance - Optimization expertise
- quality - Code quality and maintainability
- security - Security pattern application
MCP Integration
- PAL MCP - Consensus validation for complex changes
- Rube MCP - Follow-up coordination (tickets, notifications)
Evidence Requirements
This skill requires evidence. You MUST:
- Show before/after code comparisons
- Run tests to verify functionality preservation
- Report metrics (lines removed, complexity reduction)
Improvement Types
Quality (--type quality)
- Technical debt reduction
- Code structure improvements
- Readability enhancements
Performance (--type performance)
- Bottleneck resolution
- Algorithm optimization
- Resource efficiency
Maintainability (--type maintainability)
- Complexity reduction
- Documentation improvements
- Modular restructuring
Style (--type style)
- Formatting consistency
- Naming conventions
- Pattern alignment
Cleanup Mode (--cleanup)
Code Cleanup (--type code)
- Dead code detection and removal
- Unused variable elimination
- Unreachable code removal
Import Cleanup (--type imports)
- Unused import removal
- Import organization
- Dependency optimization
File Cleanup (--type files)
- Empty file removal
- Orphaned file detection
- Structure optimization
Full Cleanup (--type all)
- Comprehensive cleanup
- All categories combined
- Multi-persona coordination
Safety Modes
Safe Mode (--safe)
- Conservative changes only
- Automatic safety validation
- Preserves all functionality
Aggressive Mode (--aggressive)
- Thorough cleanup
- Framework-aware patterns
- Requires careful review
Examples
Safe Quality Improvement
/sc:improve src/ --type quality --safe
# Technical debt reduction with safety validation
Performance Optimization
/sc:improve api-endpoints --type performance --interactive
# Guided optimization with profiling analysis
Dead Code Cleanup
/sc:improve src/ --cleanup --type code --safe
# Remove unused code with dependency validation
Preview Changes
/sc:improve --cleanup --type imports --preview
# Show what would be removed without executing
Tool Coordination
- Read/Grep/Glob - Code analysis
- Edit/MultiEdit - Safe modifications
- TodoWrite - Progress tracking
- Task - Large-scale improvement delegation
