## CLI Usage Examples

### Quality Gate Management

```bash
# Check all quality gates
aqe gate check

# Check specific gate
aqe gate check coverage

# Define custom gate
cat > production-gate.json <<EOF
{
  "name": "production-ready",
  "gates": ["coverage", "performance", "security", "quality"],
  "thresholds": {
    "coverage.line": 90,
    "security.critical": 0,
    "performance.p95": 300
  }
}
EOF
aqe gate define --config production-gate.json

# Set gate thresholds
aqe gate threshold coverage --line 85 --branch 80 --function 90
aqe gate threshold performance --p95 400 --p99 800
aqe gate threshold security --critical 0 --high 0 --medium 3

# List all gates
aqe gate list

# Show gate details
aqe gate show production-ready

# Test gate without failing
aqe gate test production-ready --dry-run

# CI/CD usage
aqe gate check --fail-on-warning --json > gate-results.json
```

### Report Generation

```bash
# Generate comprehensive report
aqe report

# Generate specific report
aqe report --type coverage
aqe report --type performance
aqe report --type security

# Different formats
aqe report --format html --output report.html
aqe report --format markdown --output report.md
aqe report --format json --output report.json

# Time-based reports
aqe report --daily
aqe report --weekly

```

### Visualization Dashboard

```bash
# Start dashboard on default port (3000)
aqe visualize

# Start on custom port
aqe visualize --port 8080

# Focus on specific area
aqe visualize --focus coverage
aqe visualize --focus performance

# Export static visualization
