Code Style Audit with Auto-Fix

Purpose

Perform comprehensive code style and conventions audit across the entire codebase with automated fix capabilities. Identifies style violations, enforces naming conventions, validates formatting, and applies automated corrections to ensure consistent code quality.

Core Principles

• Automated Enforcement: Auto-fix for style violations where possible
• Comprehensive Coverage: ESLint, Prettier, TypeScript, naming conventions
• Evidence-Based: Measurable style compliance metrics
• Non-Breaking: Only applies safe, non-destructive fixes
• Continuous Compliance: Style validation at every commit

Phase 1: Scan Codebase

Objective

Identify all style violations, formatting issues, and convention inconsistencies across the codebase.

Agent Configuration

agent: code-analyzer
specialization: style-scanning
tools: ESLint, Prettier, TypeScript

Execution Steps

1. Initialize Style Scan

# Pre-task setup
npx claude-flow@alpha hooks pre-task \
  --agent-id "code-analyzer" \
  --description "Comprehensive code style scanning" \
  --task-type "style-scan"

# Restore session context
npx claude-flow@alpha hooks session-restore \
  --session-id "style-audit-${AUDIT_ID}" \
  --agent-id "code-analyzer"

2. ESLint Comprehensive Scan

# Run ESLint with all rules
npx eslint . \
  --ext .js,.jsx,.ts,.tsx \
  --format json \
  --output-file eslint-report.json \
  --max-warnings 0

# Separate auto-fixable vs manual issues
npx eslint . \
  --ext .js,.jsx,.ts,.tsx \
  --format json \
  --fix-dry-run > eslint-fixable-report.json

3. Prettier Formatting Check

# Check all supported file types
npx prettier --check "**/*.{js,jsx,ts,tsx,json,css,scss,md,yaml,yml}" \
  --list-different > prettier-violations.txt

# Check configuration consistency
npx prettier --find-config-path . > prettier-config-check.txt

4. TypeScript Style Validation

# Strict type checking
npx tsc --noEmit --strict --pretty false 2> typescript-strict-errors.txt

# Check for any types
grep -r ": any" src/ --include="*.ts" --include="*.tsx" > any-types.txt

# Check for implicit any
npx tsc --noImplicitAny --noEmit 2> implicit-any-errors.txt

5. Naming Convention Analysis

// Naming patterns validation
const namingConventions = {
  // File naming
  files: {
    pattern: /^[a-z][a-z0-9-]*\.(js|ts|jsx|tsx)$/,
    examples: ['user-service.js', 'api-client.ts'],
    violations: []
  },

  // Directory naming
  directories: {
    pattern: /^[a-z][a-z0-9-]*$/,
    examples: ['user-api', 'auth-service'],
    violations: []
  },

  // Class naming (PascalCase)
  classes: {
    pattern: /^[A-Z][a-zA-Z0-9]*$/,
    examples: ['UserService', 'ApiClient'],
    violations: []
  },

  // Function naming (camelCase)
  functions: {
    pattern: /^[a-z][a-zA-Z0-9]*$/,
    examples: ['getUserById', 'calculateTotal'],
    violations: []
  },

  // Constant naming (UPPER_SNAKE_CASE)
  constants: {
    pattern: /^[A-Z][A-Z0-9_]*$/,
    examples: ['MAX_RETRIES', 'API_BASE_URL'],
    violations: []
  },

  // React component naming (PascalCase)
  components: {
    pattern: /^[A-Z][a-zA-Z0-9]*$/,
    examples: ['UserProfile', 'LoginForm'],
    violations: []
  },

  // Private methods (leading underscore)
  privateMethods: {
    pattern: /^_[a-z][a-zA-Z0-9]*$/,
    examples: ['_validateInput', '_processData'],
    violations: []
  }
};

// Scan for naming violations
function scanNamingViolations(ast) {
  ast.walk((node) => {
    if (node.type === 'ClassDeclaration') {
      if (!namingConventions.classes.pattern.test(node.id.name)) {
        namingConventions.classes.violations.push({
          file: node.loc.source,
          line: node.loc.start.line,
          found: node.id.name,
          expected: toPascalCase(node.id.name)
        });
      }
    }
    // Similar checks for other node types...
  });
}

6. Code Organization Violations

// File organization rules
const organizationRules = {
  max_file_length: {
    threshold: 500,
    unit: 'lines',
    violations: []
  },

  max_function_length: {
    threshold: 50,
    unit: 'lines',
    violations: []
  },

  max_function_parameters: {
    threshold: 4,
    unit: 'parameters',
    violations: []
  },

  max_nesting_depth: {
    threshold: 4,
    unit: 'levels',
    violations: []
  },

  import_organization: {
    rules: [
      'External imports first',
      'Internal imports second',
      'Relative imports last',
      'Alphabetically sorted within groups'
    ],
    violations: []
  },

  export_organization: {
    rules: [
      'Named exports grouped',
      'Default export last',
      'No mixed inline and end-of-file exports'
    ],
    violations: []
  }
};

// Check file length
function checkFileLength(filePath) {
  const lines = fs.readFileSync(filePath, 'utf8').split('\n').length;
  if (lines > organizationRules.max_file_length.threshold) {
    organizationRules.max_file_length.violations.push({
      file: filePath,
      lines: lines,
      excess: lines - organizationRules.max_file_length.threshold
    });
  }
}

Phase 2: Compare to Standards

Objective

Compare scanned violations against project coding standards and industry best practices.

Agent Configuration

agent: reviewer
specialization: standards-comparison
standards: Airbnb, Google, StandardJS

Execution Steps

1. Initialize Standards Comparison

npx claude-flow@alpha hooks pre-task \
  --agent-id "reviewer" \
  --description "Compare violations to coding standards" \
  --task-type "standards-comparison"

2. Load Project Standards

// Load project coding standards
const projectStandards = {
  eslint_config: require('./.eslintrc.json'),
  prettier_config: require('./.prettierrc.json'),
  typescript_config: require('./tsconfig.json'),

  // Custom conventions
  naming_conventions: require('./docs/coding-standards.md'),
  file_organization: require('./docs/file-structure.md'),

  // Base standards
  base_standard: 'airbnb' // or 'google', 'standard'
};

3. Compare ESLint Configuration

// Check ESLint config completeness
const eslintComparison = {
  configured_rules: Object.keys(projectStandards.eslint_config.rules).length,
  airbnb_rules: 247, // Airbnb ESLint config

  missing_rules: [],
  conflicting_rules: [],
  disabled_rules: [],

  // Rule categories
  formatting_rules: 0,
  best_practices_rules: 0,
  error_prevention_rules: 0,
  es6_rules: 0
};

// Identify missing important rules
const criticalRules = [
  'no-var',
  'prefer-const',
  'no-unused-vars',
  'no-console',
  'eqeqeq',
  'no-implicit-globals',
  'strict'
];

criticalRules.forEach(rule => {
  if (!projectStandards.eslint_config.rules[rule]) {
    eslintComparison.missing_rules.push(rule);
  }
});

4. Compare Prettier Configuration

// Prettier standard comparison
const prettierComparison = {
  configured: projectStandards.prettier_config,

  recommended: {
    printWidth: 100,
    tabWidth: 2,
    useTabs: false,
    semi: true,
    singleQuote: true,
    quoteProps: 'as-needed',
    trailingComma: 'es5',
    bracketSpacing: true,
    arrowParens: 'always'
  },

  differences: []
};

// Compare configurations
Object.keys(prettierComparison.recommended).forEach(key => {
  const projectValue = projectStandards.prettier_config[key];
  const recommendedValue = prettierComparison.recommended[key];

  if (projectValue !== recommendedValue) {
    prettierComparison.differences.push({
      option: key,
      project: projectValue,
      recommended: recommendedValue
    });
  }
});

5. Assess TypeScript Strictness

// TypeScript strictness comparison
const typescriptComparison = {
  current_strictness: projectStandards.typescript_config.compilerOptions.strict || false,

  strict_options: {
    noImplicitAny: projectStandards.typescript_config.compilerOptions.noImplicitAny,
    noImplicitThis: projectStandards.typescript_config.compilerOptions.noImplicitThis,
    alwaysStrict: projectStandards.typescript_config.compilerOptions.alwaysStrict,
    strictNullChecks: projectStandards.typescript_config.compilerOptions.strictNullChecks,
    strictFunctionTypes: projectStandards.typescript_config.compilerOptions.strictFunctionTypes,
    strictBindCallApply: projectStandards.typescript_config.compilerOptions.strictBindCallApply,
    strictPropertyInitialization: projectStandards.typescript_config.compilerOptions.strictPropertyInitialization
  },

  recommended_strictness: true,

  recommendations: []
};

// Generate recommendations
if (!typescriptComparison.current_strictness) {
  typescriptComparison.recommendations.push('Enable "strict": true');
}

Object.keys(typescriptComparison.strict_options).forEach(option => {
  if (!typescriptComparison.strict_options[option]) {
    typescriptComparison.recommendations.push(`Enable "${option}": true`);
  }
});

6. Generate Standards Comparison Report

## Standards Comparison Report

### ESLint Configuration
**Configured Rules**: 178 / 247 (72.1%)
**Base Standard**: Airbnb

#### Missing Critical Rules (7)
1. `no-var` - Disallow var, use let/const
2. `prefer-const` - Prefer const for unchanged variables
3. `no-implicit-globals` - Disallow implicit global variables
4. `strict` - Require strict mode
5. `no-shadow` - Disallow variable shadowing
6. `no-param-reassign` - Disallow parameter reassignment
7. `consistent-return` - Require consistent return

#### Conflicting Rules (3)
- `indent`: Project uses 4 spaces, Airbnb recommends 2
- `quotes`: Project uses double, Airbnb recommends single
- `comma-dangle`: Project disabled, Airbnb requires

#### Disabled Important Rules (5)
- `no-console` - Currently disabled, should be error
- `no-debugger` - Currently disabled, should be error
- `no-alert` - Currently disabled, should be warning

### Prettier Configuration
**Configuration Completeness**: 8 / 9 options (88.9%)

#### Configuration Differences from Recommended
| Option | Project | Recommended | Impact |
|--------|---------|-------------|--------|
| `singleQuote` | false | true | Inconsistent with ESLint |
| `printWidth` | 80 | 100 | More line breaks than needed |

### TypeScript Configuration
**Strict Mode**: ❌ Disabled
**Individual Strict Checks**: 3 / 7 enabled (42.9%)

#### Recommendations
1. Enable `"strict": true` (enables all strict checks)
2. Enable `noImplicitAny` for better type safety
3. Enable `strictNullChecks` to catch null/undefined errors
4. Enable `strictFunctionTypes` for safer function typing

### Naming Conventions
**Documented**: ✅ Yes (docs/coding-standards.md)
**Enforced**: ⚠️ Partial (ESLint naming rules not configured)

#### Recommendations
1. Add `@typescript-eslint/naming-convention` rule
2. Configure naming patterns for:
   - Classes (PascalCase)
   - Functions/variables (camelCase)
   - Constants (UPPER_SNAKE_CASE)
   - Private members (leading underscore)

### File Organization
**Max File Length**: 500 lines ✅
**Max Function Length**: 50 lines ✅
**Import Ordering**: ⚠️ Not enforced

#### Recommendations
1. Add `import/order` ESLint rule
2. Configure import groups:
   - External dependencies
   - Internal modules
   - Relative imports

7. Store Comparison Results

npx claude-flow@alpha hooks post-edit \
  --file "standards-comparison-report.json" \
  --memory-key "swarm/reviewer/standards-comparison" \
  --metadata "{\"compliance_pct\": ${COMPLIANCE_PCT}, \"missing_rules\": ${MISSING_RULES_COUNT}}"

Validation Gates

• ✅ Standards documented
• ✅ Comparison complete
• ✅ Gaps identified
• ✅ Recommendations generated

Expected Outputs

• standards-comparison-report.json - Detailed comparison
• missing-rules.json - Rules to add
• config-recommendations.json - Configuration improvements

Phase 3: Report Violations

Objective

Generate comprehensive violation reports with prioritization, categorization, and fix recommendations.

Agent Configuration

agent: code-analyzer
specialization: violation-reporting
output: HTML, JSON, Markdown

Execution Steps

1. Initialize Violation Reporting

npx claude-flow@alpha hooks pre-task \
  --agent-id "code-analyzer" \
  --description "Generate violation reports" \
  --task-type "violation-reporting"

2. Prioritize Violations

// Prioritization criteria
const violationPriority = {
  P0_CRITICAL: {
    description: 'Breaking production issues, security risks',
    examples: ['no-eval', 'no-implied-eval', 'no-script-url'],
    violations: []
  },

  P1_HIGH: {
    description: 'Potential bugs, code smells',
    examples: ['no-unused-vars', 'no-unreachable', 'no-fallthrough'],
    violations: []
  },

  P2_MEDIUM: {
    description: 'Best practices, maintainability',
    examples: ['prefer-const', 'no-var', 'eqeqeq'],
    violations: []
  },

  P3_LOW: {
    description: 'Formatting, style consistency',
    examples: ['indent', 'quotes', 'comma-dangle'],
    violations: []
  }
};

// Categorize violations by priority
function prioritizeViolations(violations) {
  violations.forEach(violation => {
    const rule = violation.ruleId;

    if (violationPriority.P0_CRITICAL.examples.includes(rule)) {
      violationPriority.P0_CRITICAL.violations.push(violation);
    } else if (violationPriority.P1_HIGH.examples.includes(rule)) {
      violationPriority.P1_HIGH.violations.push(violation);
    } else if (violationPriority.P2_MEDIUM.examples.includes(rule)) {
      violationPriority.P2_MEDIUM.violations.push(violation);
    } else {
      violationPriority.P3_LOW.violations.push(violation);
    }
  });
}

3. Categorize by File/Module

// Group violations by file
const violationsByFile = {};

function categorizeByFile(violations) {
  violations.forEach(violation => {
    const file = violation.filePath;

    if (!violationsByFile[file]) {
      violationsByFile[file] = {
        file: file,
        total_violations: 0,
        critical: 0,
        high: 0,
        medium: 0,
        low: 0,
        violations: []
      };
    }

    violationsByFile[file].violations.push(violation);
    violationsByFile[file].total_violations++;

    // Increment priority counters
    if (violation.priority === 'P0_CRITICAL') violationsByFile[file].critical++;
    if (violation.priority === 'P1_HIGH') violationsByFile[file].high++;
    if (violation.priority === 'P2_MEDIUM') violationsByFile[file].medium++;
    if (violation.priority === 'P3_LOW') violationsByFile[file].low++;
  });

  // Sort by total violations descending
  return Object.values(violationsByFile)
    .sort((a, b) => b.total_violations - a.total_violations);
}

4. Generate Fix Recommendations

// Auto-fix recommendations
const fixRecommendations = {
  auto_fixable: {
    count: 0,
    script: 'npx eslint . --fix && npx prettier --write "**/*.{js,ts,jsx,tsx}"',
    violations: []
  },

  semi_auto_fixable: {
    count: 0,
    description: 'Requires code review after auto-fix',
    violations: []
  },

  manual_fix_required: {
    count: 0,
    description: 'Requires human judgment and refactoring',
    violations: []
  }
};

// Generate fix instructions for each violation
function generateFixInstructions(violation) {
  const instructions = {
    rule: violation.ruleId,
    file: violation.filePath,
    line: violation.line,
    column: violation.column,

    fix_type: 'auto', // 'auto', 'semi-auto', 'manual'
    fix_command: null,
    fix_description: null,

    before: violation.source,
    after: null
  };

  // Rule-specific fix instructions
  switch (violation.ruleId) {
    case 'no-unused-vars':
      instructions.fix_type = 'manual';
      instructions.fix_description = 'Remove unused variable or add usage';
      break;

    case 'prefer-const':
      instructions.fix_type = 'auto';
      instructions.fix_command = 'npx eslint --fix';
      instructions.after = violation.source.replace('let ', 'const ');
      break;

    case 'no-console':
      instructions.fix_type = 'manual';
      instructions.fix_description = 'Remove console.log or use proper logging';
      break;

    // Add more rule-specific instructions...
  }

  return instructions;
}

5. Generate Violation Reports

### Critical Violations (P0) ✅
**None found** - Excellent!

### High Priority Violations (P1) - 34 Total

#### no-unused-vars (34 occurrences)
**Impact**: Dead code, maintenance burden, potential bugs

**Example**:
```javascript
// src/api/user-controller.js:45
const userId = req.params.id; // 'userId' is defined but never used

Fix: Remove unused variable or add usage

---

no-console (23 occurrences)

Impact: Console statements in production code

Example:

// src/services/payment.js:78
console.log('Processing payment:', paymentData); // Unexpected console statement

Fix: Replace with proper logging (Winston, Bunyan)

Medium Priority Violations (P2) - 73 Total

prefer-const (28 occurrences) - AUTO-FIXABLE ✅

Impact: Mutability when immutability intended

Example:

// src/utils/calculator.js:23
let total = 0; // 'total' is never reassigned. Use 'const' instead
total = items.reduce((sum, item) => sum + item.price, 0);

Fix: Run npx eslint --fix

Low Priority Violations (P3) - 140 Total

indent (67 occurrences) - AUTO-FIXABLE ✅

Impact: Inconsistent formatting

Fix: Run npx prettier --write "**/*.js"

---

Phase 4: Auto-Fix Issues

Objective

Apply automated fixes for style violations that can be safely corrected without human judgment.

Agent Configuration

agent: code-analyzer
specialization: auto-fix
safety: non-destructive

Execution Steps

1. Initialize Auto-Fix

npx claude-flow@alpha hooks pre-task \
  --agent-id "code-analyzer" \
  --description "Apply automated style fixes" \
  --task-type "auto-fix"

2. Create Backup

# Create backup before applying fixes
BACKUP_DIR="style-audit-backup-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$BACKUP_DIR"

# Backup modified files
git diff --name-only | while read file; do
  mkdir -p "$BACKUP_DIR/$(dirname "$file")"
  cp "$file" "$BACKUP_DIR/$file"
done

echo "Backup created: $BACKUP_DIR"

3. Apply ESLint Auto-Fixes

# Apply all auto-fixable ESLint rules
npx eslint . --fix \
  --ext .js,.jsx,.ts,.tsx \
  --format json \
  --output-file eslint-fix-results.json

# Count fixed issues
FIXED_COUNT=$(jq '[.[] | .messages | .[] | select(.fix)] | length' eslint-fix-results.json)
echo "ESLint fixed: $FIXED_COUNT issues"

4. Apply Prettier Formatting

# Format all supported files
npx prettier --write "**/*.{js,jsx,ts,tsx,json,css,scss,md,yaml,yml}" \
  --log-level warn > prettier-fix-log.txt

# Count formatted files
FORMATTED_COUNT=$(grep -c "✅" prettier-fix-log.txt)
echo "Prettier formatted: $FORMATTED_COUNT files"

5. Apply TypeScript Fixes

# Apply TypeScript compiler fixes (where possible)
npx tsc --noEmit --pretty false 2>&1 | \
  node scripts/apply-typescript-fixes.js

# Note: Most TypeScript issues require manual intervention

6. Apply Naming Convention Fixes (Safe)

// Safe automated naming fixes
const safeNamingFixes = {
  // File naming: PascalCase → kebab-case

Phase 5: Validate Compliance

Objective

Verify that all auto-fixes were applied correctly and confirm adherence to coding standards.

Agent Configuration

agent: reviewer
specialization: compliance-validation
verification: automated-tests

Execution Steps

1. Initialize Compliance Validation

npx claude-flow@alpha hooks pre-task \
  --agent-id "reviewer" \
  --description "Validate style compliance after fixes" \
  --task-type "compliance-validation"

2. Run Comprehensive Linting

# ESLint validation
npx eslint . \
  --ext .js,.jsx,.ts,.tsx \
  --format json \
  --max-warnings 0 > eslint-validation.json

# Prettier validation
npx prettier --check "**/*.{js,jsx,ts,tsx,json,css,md}" > prettier-validation.txt

# TypeScript validation
npx tsc --noEmit --strict > typescript-validation.txt

3. Calculate Compliance Metrics

// Compliance calculation
const complianceMetrics = {
  eslint: {
    total_rules: 247,
    passing_rules: 0,
    failing_rules: 0,
    compliance_pct: 0
  },

  prettier: {
    total_files: 0,
    formatted_files: 0,
    unformatted_files: 0,
    compliance_pct: 0
  },

  typescript: {
    total_files: 0,
    error_free_files: 0,
    files_with_errors: 0,
    compliance_pct: 0
  },

  naming_conventions: {
    total_identifiers: 0,
    compliant_identifiers: 0,
    non_compliant_identifiers: 0,
    compliance_pct: 0
  },

  overall_compliance_pct: 0
};

// Calculate overall compliance
function calculateCompliance() {
  // ESLint compliance
  const eslintViolations = require('./eslint-validation.json');
  const totalIssues = eslintViolations.reduce((sum, file) =>
    sum + file.messages.length, 0
  );
  complianceMetrics.eslint.failing_rules = totalIssues;
  complianceMetrics.eslint.compliance_pct =
    ((complianceMetrics.eslint.total_rules - totalIssues) /
     complianceMetrics.eslint.total_rules) * 100;

  // Prettier compliance
  const prettierViolations = fs.readFileSync('prettier-validation.txt', 'utf8');
  const unformattedFiles = prettierViolations.split('\n').filter(Boolean).length;
  complianceMetrics.prettier.unformatted_files = unformattedFiles;
  complianceMetrics.prettier.compliance_pct =
    ((complianceMetrics.prettier.total_files - unformattedFiles) /
     complianceMetrics.prettier.total_files) * 100;

  // Calculate weighted overall compliance
  complianceMetrics.overall_compliance_pct = (
    complianceMetrics.eslint.compliance_pct * 0.50 +
    complianceMetrics.prettier.compliance_pct * 0.30 +
    complianceMetrics.typescript.compliance_pct * 0.20
  );
}

4. Run Test Suite

# Verify no regressions from auto-fixes
npm run test:all -- --coverage

# Check for test failures
if [ $? -ne 0 ]; then
  echo "❌ Tests failed after auto-fix"
  echo "Rolling back changes..."
  git restore .
  exit 1
fi

5. Validate Build

# Ensure project still builds
npm run build

# Check build size (ensure no significant increase)
BUILD_SIZE=$(du -sh dist/ | cut -f1)
echo "Build size: $BUILD_SIZE"

6. Generate Compliance Report

## Style Compliance Validation Report
