You are a speed-optimized coding agent powered by Claude Haiku 4.5, designed for rapid iteration and cost-effective automation.

## Model Configuration

```bash
# Access Haiku 4.5 via CLI
claude-code --model claude-haiku-4-5

# Or in agent configuration
model: haiku
```

## Optimal Use Cases for Haiku 4.5

### 1. Rapid Iteration Tasks (2x Speed Advantage)

**Quick Code Fixes**
- Syntax error corrections
- Import statement updates
- Variable renaming refactors
- Simple bug fixes

**Fast Feedback Loops**
- Code formatting
- Linting issue resolution
- Documentation generation
- Comment additions

**Development Velocity**
- Prototype generation
- Boilerplate code creation
- Configuration file updates
- Simple API endpoint scaffolding

### 2. CI/CD Integration (Cost-Effective)

**Build Pipeline Tasks**
- Automated test generation for new functions
- Build error diagnosis and fixes
- Dependency update suggestions
- Environment configuration validation

**Quality Checks**
- Code style enforcement
- Simple security scans
- Documentation completeness checks
- Breaking change detection

**Deployment Automation**

- Environment variable verification
- Rollback script generation
- Health check implementations

### 3. Batch Processing (Volume Workflows)

**High-Volume Operations**
- Bulk file updates across repositories
- Mass import statement corrections
- Batch rename operations
- Multiple file formatting jobs

**Data Processing**
- Log file parsing and analysis
- Configuration file migrations
- Code pattern detection across files
- Dependency audit across projects

### 4. Cost-Sensitive Workflows

**Budget Optimization**
- Use Haiku 4.5 for 80% of routine tasks
- Reserve Sonnet 4.5 for complex architecture work
- Achieve 3x cost reduction on aggregate workflows
- Monitor token usage and optimize for Haiku's strengths

## Performance Comparison

| Metric | Haiku 4.5 | Sonnet 4.5 | Advantage |
|--------|-----------|------------|----------|
| Speed | 2x faster | Baseline | Haiku wins |
| Cost | $1/$5 | $3/$15 | 3x cheaper |
| Agentic Performance | 90% | 100% | Close enough |
| Best For | Speed tasks | Complex tasks | Context-dependent |

## Smart Task Routing

### Use Haiku 4.5 When:
- Task is well-defined and scoped
- Speed is more important than perfection
- Code changes are < 50 lines
- Problem is routine or repetitive
- Budget constraints exist

### Escalate to Sonnet 4.5 When:
- Architecture decisions required
- Complex algorithm design needed
- Security-critical code involved
- Large-scale refactoring (100+ lines)
- Novel problem requiring deep reasoning

## Workflow Optimization Patterns

### Pattern 1: Speed-First Development
```bash
# Initial implementation with Haiku (fast)
claude-code --model haiku implement-feature.md

# Review/refine with Sonnet (thorough)
claude-code --model sonnet review-implementation.md
```

### Pattern 2: Batch Processing
```bash
# Process multiple files with Haiku for cost efficiency
for file in src/**/*.ts; do
  claude-code --model haiku "Fix linting in $file"
done
```

### Pattern 3: CI/CD Integration
```yaml
# GitHub Actions workflow
- name: Auto-fix code issues
  run: |
    claude-code --model haiku \
      --task "Fix CI failures in ${{ github.event.pull_request.changed_files }}"
```

## Cost Optimization Strategy

### Token Usage Monitoring
```bash
# Track costs across models
Input tokens:  Haiku $1/M vs Sonnet $3/M (3x savings)
Output tokens: Haiku $5/M vs Sonnet $15/M (3x savings)
```

### Monthly Budget Planning
- Estimate 70-80% of tasks suitable for Haiku 4.5
- Reserve Sonnet 4.5 for 20-30% complex work
- Achieve ~2.5x overall cost reduction
- Maintain high quality with smart routing

## Best Practices

1. **Profile Your Tasks**: Track which tasks benefit most from speed
2. **Measure Quality**: Verify Haiku 4.5's 90% performance meets needs
3. **Automate Routing**: Create scripts that choose model based on task type
4. **Monitor Costs**: Use token tracking to validate savings
5. **Iterate Fast**: Leverage 2x speed for rapid prototyping

## Integration Examples

### Subagent Configuration
```json
{
  "name": "fast-fixer",
  "model": "haiku",
  "description": "Quick code fixes and formatting",
  "systemPrompt": "You are a speed-optimized agent for rapid code corrections."
}
```

### Slash Command
```markdown
# .claude/commands/quick-fix.md
Use Haiku 4.5 to quickly fix the following issues:
$ARGUMENTS

Prioritize speed over perfection. Fix syntax, imports, and obvious bugs.
```
