# Capture Baseline Metrics

## Initial data:
 - Problem description: `@_docs/00_problem/problem_description.md`
 - Acceptance criteria: `@_docs/00_problem/acceptance_criteria.md`
 - Current codebase

## Role
  You are a software engineer preparing for refactoring

## Task
 - Capture current system metrics as baseline
 - Document current behavior
 - Establish benchmarks to compare against after refactoring
 - Identify critical paths to monitor

## Output

### Code Quality Metrics

#### Coverage
```
Current test coverage: XX%
- Unit test coverage: XX%
- Integration test coverage: XX%
- Critical paths coverage: XX%
```

#### Code Complexity
- Cyclomatic complexity (average): 
- Most complex functions (top 5):
- Lines of code:
- Technical debt ratio:

#### Code Smells
- Total code smells:
- Critical issues:
- Major issues:

### Performance Metrics

#### Response Times
| Endpoint/Operation | P50 | P95 | P99 |
|-------------------|-----|-----|-----|
| [endpoint1] | Xms | Xms | Xms |
| [operation1] | Xms | Xms | Xms |

#### Resource Usage
- Average CPU usage:
- Average memory usage:
- Database query count per operation:

#### Throughput
- Requests per second:
- Concurrent users supported:

### Functionality Inventory

List all current features/endpoints:
| Feature | Status | Test Coverage | Notes |
|---------|--------|---------------|-------|
| | | | |

### Dependency Analysis
- Total dependencies:
- Outdated dependencies:
- Security vulnerabilities in dependencies:

### Build Metrics
- Build time:
- Test execution time:
- Deployment time:

## Measurement Commands

Use project-appropriate tools for your tech stack:

| Metric | Python | C#/.NET | Java | Go | JavaScript/TypeScript |
|--------|--------|---------|------|-----|----------------------|
| Test coverage | pytest --cov | dotnet test --collect | jacoco | go test -cover | jest --coverage |
| Code complexity | radon | CodeMetrics | PMD | gocyclo | eslint-plugin-complexity |
| Lines of code | cloc | cloc | cloc | cloc | cloc |
| Dependency check | pip-audit | dotnet list package --vulnerable | mvn dependency-check | govulncheck | npm audit |

## Notes
 - Run measurements multiple times for accuracy
 - Document measurement methodology
 - Save raw data for comparison
 - Focus on metrics relevant to refactoring goals
