## Integration

### GitHub Actions

```yaml

            github.rest.issues.createComment({
              issue_number: context.issue.number,
              owner: context.repo.owner,
              repo: context.repo.repo,
              body: report
            });
```

### Pre-commit Hook

```bash
#!/bin/bash
# .git/hooks/pre-commit

# Check excellence metrics
pmat excellence-tracker --quick-check
if [ $? -ne 0 ]; then
    echo "❌ Excellence standards not met!"
    echo "Run 'pmat excellence-tracker' for details"
    exit 1
fi
```

## Scoring Algorithm

The overall excellence score is calculated using weighted metrics:

```
Score = (
    Coverage * 0.25 +
    (100 - Complexity) * 0.20 +
    TypeSafety * 0.20 +
    Documentation * 0.15 +
    Performance * 0.10 +
    DependencyHealth * 0.10
)
```

### Metric Calculations

#### Coverage Score
```
coverage_score = (line_coverage * 0.5 + branch_coverage * 0.3 + function_coverage * 0.2)
```

#### Complexity Score
```
complexity_score = 100 * (1 - (avg_complexity / max_allowed_complexity))
```

#### Type Safety Score
```
type_safety_score = 100 * (typed_lines / total_lines) * (1 - unsafe_usage_ratio)
```

### Alerts and Notifications

```json
{
  "alert": {
    "type": "threshold_breach",
    "metric": "complexity",
    "current": 22.5,
    "threshold": 20,
    "trend": "increasing",
    "files_affected": [
      "src/cli/mod.rs",
      "src/services/analyzer.rs"
    ],
    "recommendation": "Consider refactoring high-complexity functions"
  }
}
```

## Best Practices

1. **Set Realistic Thresholds**: Start with achievable goals and gradually increase
2. **Track Trends**: Focus on improvement over time rather than absolute values
3. **Automate Monitoring**: Integrate with CI/CD for continuous tracking
4. **Team Visibility**: Share reports in team channels or dashboards
5. **Act on Insights**: Use data to guide refactoring and improvement efforts

## Custom Metrics

### Adding Custom Metrics

```rust
use paiml_mcp_agent_toolkit::excellence::{Metric, MetricResult};

pub struct SecurityMetric;

impl Metric for SecurityMetric {
    fn name(&self) -> &'static str {
        "security"
    }
    
    fn calculate(&self, project: &Project) -> MetricResult {
        let vulnerabilities = scan_vulnerabilities(project);
        let score = 100.0 * (1.0 - (vulnerabilities.len() as f32 / 100.0));
        
        MetricResult {
            score,
            details: json!({
                "vulnerabilities": vulnerabilities,
                "last_scan": Utc::now()
            })
        }
    }
}
```

### Registering Custom Metrics

```toml
# excellence-config.toml
[custom_metrics]
security = { path = "./metrics/security.wasm", weight = 0.15 }
accessibility = { path = "./metrics/a11y.wasm", weight = 0.10 }
```

## Troubleshooting

### Common Issues

**Q: Excellence tracker is slow**
A: Use `--quick-check` for faster results or adjust the analysis depth in config.

**Q: Metrics seem incorrect**
A: Ensure all build artifacts are fresh. Run `make clean && make build` first.

**Q: Missing coverage data**
A: Make sure tests are run with coverage enabled: `cargo test --coverage`

## Future Enhancements

- **AI-Powered Insights**: ML-based recommendations for improvement
- **Team Dashboards**: Web interface for team-wide visibility
- **Historical Analysis**: Long-term trend analysis and predictions
