Features and Capabilities

Compliance-Aware Code Generation

Claude Code understands regulatory requirements and generates code that adheres to compliance standards:

// Example: AI-generated authentication code with ISO 13485 compliance
class UserAuthentication {
  // Generated with ISO 13485 audit trail requirements
  async authenticateUser(credentials: UserCredentials): Promise<AuthResult> {
    // Audit trail logging (ISO 13485 requirement)
    await this.auditLogger.log({
      action: 'authentication_attempt',
      userId: credentials.username,
      timestamp: new Date(),
      ipAddress: this.getClientIP(),
      userAgent: this.getUserAgent(),
    });

    try {
      const user = await this.validateCredentials(credentials);

      if (!user) {
        // Log failed authentication (security requirement)
        await this.auditLogger.log({
          action: 'authentication_failed',
          userId: credentials.username,
          reason: 'invalid_credentials',
          timestamp: new Date(),
        });

        throw new AuthenticationError('Invalid credentials');
      }

      // Generate secure session token
      const sessionToken = await this.generateSecureToken(user);

      // Log successful authentication
      await this.auditLogger.log({
        action: 'authentication_success',
        userId: user.id,
        sessionId: sessionToken.id,
        timestamp: new Date(),
      });

      return {
        user,
        token: sessionToken,
        expiresAt: sessionToken.expiresAt,
      };
    } catch (error) {
      // Ensure all errors are logged for compliance
      await this.auditLogger.log({
        action: 'authentication_error',
        userId: credentials.username,
        error: error.message,
        timestamp: new Date(),
      });

      throw error;
    }
  }
}

Real-Time Compliance Validation

As you write code, Claude Code provides real-time feedback on compliance implications:

// Real-time validation example
function processPatientData(data: PatientData) {
  // ⚠️ Claude Code Warning: Processing patient data requires audit logging (ISO 13485)
  // 💡 Suggestion: Add audit trail logging before processing

  const processedData = transformData(data);

  // ❌ Claude Code Error: Patient data must be encrypted at rest (HIPAA/GDPR)
  // 💡 Suggestion: Use encryptSensitiveData() before storage

  return processedData;
}

// Claude Code suggested improvement:
function processPatientDataCompliant(data: PatientData) {
  // ✅ Audit logging added
  auditLogger.log({
    action: 'patient_data_processing',
    dataType: 'patient_record',
    timestamp: new Date(),
  });

  const processedData = transformData(data);

  // ✅ Encryption added for compliance
  const encryptedData = encryptSensitiveData(processedData);

  return encryptedData;
}

Requirement Traceability

Claude Code automatically links code to specific compliance requirements:

/**
 * User Access Control Implementation
 *
 * @compliance ISO13485 REQ-ISO-001 Quality Management System
 * @compliance FDA21CFR11 REQ-FDA-001 Access Control
 * @compliance SOC2 CC6.1 Logical and Physical Access Controls
 *
 * This implementation satisfies:
 * - User authentication and authorization
 * - Role-based access control
 * - Audit trail generation
 * - Session management
 */
class AccessControlSystem {
  // Implementation automatically traced to requirements
}

Documentation Generation

Claude Code can generate compliance documentation from your code:

<!-- Auto-generated by Claude Code -->

# Access Control Implementation Documentation

## Compliance Mapping

### ISO 13485 Requirements

- **REQ-ISO-001**: Quality Management System
  - Implementation: `AccessControlSystem.authenticateUser()`
  - Evidence: Audit logs, user session tracking
  - Status: ✅ Implemented

### FDA 21 CFR Part 11 Requirements

- **REQ-FDA-001**: Access Control
  - Implementation: `RoleBasedAccessControl.checkPermissions()`
  - Evidence: Permission matrices, access logs
  - Status: ✅ Implemented

## Security Controls

### Authentication Flow

1. User provides credentials
2. System validates against secure store
3. Audit event logged
4. Session token generated
5. Access permissions assigned

### Audit Trail

All access control events are logged with:

- User identification
- Timestamp (UTC)
- Action performed
- Result (success/failure)
- IP address and user agent

Advanced Features

Custom Compliance Rules

Define custom compliance rules for your specific requirements:

// .supernal/claude-rules.json
{
  "customRules": [
    {
      "id": "medical-device-logging",
      "name": "Medical Device Audit Logging",
      "description": "All patient data access must be logged",
      "pattern": "function.*patient.*data|class.*Patient.*",
      "requirement": "Add audit logging for patient data access",
      "severity": "error",
      "frameworks": ["iso13485", "hipaa"]
    },
    {
      "id": "encryption-requirement",
      "name": "Data Encryption Requirement",
      "description": "Sensitive data must be encrypted",
      "pattern": "store|save|persist.*sensitive|patient|medical",
      "requirement": "Use encryption for sensitive data storage",
      "severity": "warning",
      "frameworks": ["gdpr", "hipaa"]
    }
  ]
}

Integration with Git Workflows

Claude Code integrates with Git to provide compliance validation during development:

# Git hook integration
#!/bin/bash
# .git/hooks/pre-commit

echo "Running Claude Code compliance validation..."

# Validate changed files
changed_files=$(git diff --cached --name-only | grep -E '\.(ts|js|py)$')

for file in $changed_files; do
  # Run Claude Code validation
  claude-code validate "$file" --framework=iso13485

  if [ $? -ne 0 ]; then
    echo "❌ Compliance validation failed for $file"
    echo "Run 'claude-code fix $file' to auto-fix issues"
    exit 1
  fi
done

echo "✅ All files pass compliance validation"

Automated Compliance Testing

Generate compliance tests automatically:

// Auto-generated compliance tests by Claude Code
describe('User Authentication Compliance Tests', () => {
  describe('ISO 13485 Requirements', () => {
    test('should log all authentication attempts', async () => {
      const mockAuditLogger = jest.fn();
      const authService = new UserAuthentication(mockAuditLogger);

      await authService.authenticateUser({
        username: 'testuser',
        password: 'testpass',
      });

      expect(mockAuditLogger).toHaveBeenCalledWith(
        expect.objectContaining({
          action: 'authentication_attempt',
          userId: 'testuser',
          timestamp: expect.any(Date),
        })
      );
    });

    test('should encrypt sensitive data before storage', async () => {
      const userData = { ssn: '123-45-6789', medicalId: 'MED123' };
      const encrypted = await encryptSensitiveData(userData);

      expect(encrypted).not.toContain('123-45-6789');
      expect(encrypted).not.toContain('MED123');
      expect(encrypted.encrypted).toBe(true);
    });
  });
});

Best Practices

Code Organization

Structure your code to maximize Claude Code's compliance assistance:

// Good: Clear separation of concerns with compliance annotations
@ComplianceFramework(['iso13485', 'fda21cfr11'])
class MedicalDeviceController {
  @AuditTrail('patient_data_access')
  @RequirePermission('read_patient_data')
  async getPatientData(patientId: string): Promise<PatientData> {
    // Implementation with built-in compliance
  }

  @AuditTrail('patient_data_modification')
  @RequirePermission('write_patient_data')
  @ValidateInput(PatientDataSchema)
  async updatePatientData(patientId: string, data: PatientData): Promise<void> {
    // Implementation with validation and audit
  }
}

Configuration Management

Use environment-specific configurations:

// config/compliance.ts
export const complianceConfig = {
  development: {
    framework: 'iso13485',
    strictMode: false,
    auditLevel: 'basic',
  },
  staging: {
    framework: 'iso13485',
    strictMode: true,
    auditLevel: 'detailed',
  },
  production: {
    framework: 'iso13485',
    strictMode: true,
    auditLevel: 'comprehensive',
    encryptionRequired: true,
  },
};

Troubleshooting

Common Issues

Issue: Claude Code not providing compliance suggestions

# Solution: Verify API key and framework configuration
claude-code config check
claude-code auth verify

Issue: False positive compliance warnings

// Solution: Add exception rules
{
  "exceptions": [
    {
      "rule": "audit-logging",
      "files": ["test/**/*", "mock/**/*"],
      "reason": "Test files don't require audit logging"
    }
  ]
}

Issue: Performance impact from real-time validation

// Solution: Adjust validation settings
{
  "supernal-coding.claude-code.validation": {
    "mode": "on-save", // Instead of "real-time"
    "debounceMs": 1000,
    "maxFileSize": "1MB"
  }
}
