Code Simplification Analysis

Analyze codebase (or specific section) for complexity and consistency using 5 specialized sub-agents. Each agent performs 3 iterative passes to identify and suggest simplifications while maintaining alignment with existing patterns.

Target Path: $ARGUMENTS (defaults to current directory)

Sub-Agent Framework:

1. Pattern Consistency Agent

Ensures code follows established patterns in the codebase.

Pass 1 - Pattern Discovery:

• Identify common patterns across the codebase:
  • Naming conventions (variables, functions, classes)
  • File organization patterns
  • Import/export structures
  • Error handling patterns
  • API response patterns
  • Component structure patterns

Pass 2 - Deviation Detection:

• Find code that deviates from established patterns
• Identify inconsistent implementations of similar functionality
• Detect mixed paradigms (e.g., callbacks vs promises vs async/await)
• Find naming convention violations

Pass 3 - Standardization Proposals:

• Suggest refactoring to match dominant patterns
• Provide specific code changes to align with conventions
• Prioritize changes by impact and effort

2. Code Complexity Agent

Identifies and reduces unnecessary complexity.

Pass 1 - Complexity Metrics:

• Calculate cyclomatic complexity for each function
• Identify deeply nested code blocks (>3 levels)
• Find functions with too many parameters (>4)
• Detect overly long functions (>50 lines)
• Identify complex conditional statements

Pass 2 - Simplification Opportunities:

• Functions that can be decomposed
• Complex conditionals that can use early returns
• Nested callbacks that can be flattened
• Switch statements that can use lookup tables
• Loops that can use functional approaches

Pass 3 - Refactoring Recommendations:

• Provide specific refactoring suggestions
• Show before/after code examples
• Estimate complexity reduction
• Ensure functionality preservation

3. DRY Principle Agent

Eliminates code duplication and promotes reusability.

Pass 1 - Duplication Detection:

• Find exact code duplicates
• Identify similar code patterns with minor variations
• Detect repeated logic across files
• Find duplicated type definitions
• Identify copy-pasted error handling

Pass 2 - Abstraction Opportunities:

• Common functions that can be extracted
• Shared utilities that should be centralized
• Repeated patterns that need templates
• Similar components that can be generalized
• Duplicate configs that can be merged

Pass 3 - Consolidation Plan:

• Create shared utility modules
• Suggest generic implementations
• Provide migration path for duplicates
• Estimate code reduction metrics

4. Abstraction Level Agent

Ensures appropriate levels of abstraction.

Pass 1 - Abstraction Analysis:

• Identify over-engineered solutions
• Find premature optimizations
• Detect unnecessary design patterns
• Locate overly generic implementations
• Find abstraction layer violations

Pass 2 - Simplification Targets:

• Abstractions used only once
• Interfaces with single implementations
• Factory patterns for simple objects
• Unnecessary inheritance hierarchies
• Over-configured systems

Pass 3 - De-abstraction Proposals:

• Suggest direct implementations
• Remove unnecessary layers
• Simplify configuration systems
• Inline single-use abstractions
• Balance flexibility vs complexity

5. Dependency Simplification Agent

Optimizes dependencies and coupling.

Pass 1 - Dependency Analysis:

• Map import/require statements
• Identify circular dependencies
• Find unused dependencies
• Detect over-coupling between modules
• Analyze external package usage

Pass 2 - Optimization Opportunities:

• Unused imports to remove
• Circular dependencies to break
• Tightly coupled modules to decouple
• External packages that can be replaced with native code
• Heavy dependencies used for simple features

Pass 3 - Restructuring Plan:

• Suggest dependency injection where needed
• Provide decoupling strategies
• Recommend native alternatives
• Show impact on bundle size
• Ensure no functionality loss
