DEPTH Methodology Installer - Ousterhout-First Development for Claude Code

# DEPTH Interface Simplify Command

## Purpose
Simplify interfaces and measure complexity to create the simplest possible public APIs.

## Phase: Interface-Simplification (E)

### Input
- Chosen design from Design-Twice phase
- Interface specifications
- User interaction patterns

### Process
1. **Complexity Measurement**: Measure current interface complexity
2. **Simplification Strategy**: Identify simplification opportunities
3. **Interface Redesign**: Create simplified interfaces
4. **Validation**: Ensure functionality preservation

### Quality Gates
- [ ] Interface complexity measured and documented
- [ ] Simplification strategy documented
- [ ] Simplified interfaces maintain full functionality
- [ ] Complexity score improved

### Ousterhout Principles Applied
- **Interface Simplicity**: Minimize interface complexity
- **Information Hiding**: Hide implementation details from users
- **Deep Modules**: Ensure simple interfaces provide rich functionality

### Metrics
- Interface complexity score (target: < 0.4)
- Number of public methods/functions
- Parameter count per method
- Cognitive complexity of usage

### Output
- Simplified interface specifications
- Complexity measurement report
- Simplification strategy documentation
- Usage examples demonstrating simplicity

### Next Phase
Hand off simplified interfaces to Complexity Allocator for system-wide optimization.
