Avg cyclomatic complexity 4.6
Avg cognitive complexity 3.5
Max cyclomatic complexity 27 ⚠️

Top 3 Most Complex Functions

1. 🔴 fix-duplicate-project-ids.ts (lines 39-223)

File: backend/scripts/fix-duplicate-project-ids.ts

Metric Value Status
Cyclomatic complexity 27 🔴 HIGH (270% over threshold)
Cognitive complexity 25 🔴 HIGH (167% over threshold)
Function length 185 lines 🔴 VERY HIGH (370% over threshold)
Nesting depth 2 ✅ OK

Issues:

  • Very high cyclomatic complexity (27) - indicates many decision points
  • Very high cognitive complexity (25) - difficult to understand and maintain
  • Extremely long function (185 lines) - should be broken into smaller functions

Recommendation: HIGH PRIORITY - Break this function into multiple smaller, focused functions. Aim for <50 lines per function and <10 cyclomatic complexity.


2. ⚠️ useFilterPersistence.ts (lines 57-122)

File: ui/src/hooks/useFilterPersistence.ts

Metric Value Status
Cyclomatic complexity 7 ✅ OK
Cognitive complexity 15 ⚠️ AT THRESHOLD
Function length 66 lines ⚠️ SLIGHTLY HIGH (32% over threshold)
Nesting depth 2 ✅ OK

Issues:

  • Cognitive complexity at threshold (15) - could be simplified
  • Slightly long (66 lines) - consider extracting helper functions

Recommendation: MEDIUM PRIORITY - Extract helper functions for persistence logic to reduce cognitive load.


3. ⚠️ create-cors-alerts.ts (lines 64-178)

File: backend/scripts/create-cors-alerts.ts

Metric Value Status
Cyclomatic complexity 13 ⚠️ HIGH (30% over threshold)
Cognitive complexity 9 ✅ OK
Function length 115 lines 🔴 VERY HIGH (230% over threshold)
Nesting depth 2 ✅ OK

Issues:

  • High cyclomatic complexity (13) - many decision branches
  • Very long function (115 lines) - should be split up

Recommendation: MEDIUM PRIORITY - Break into smaller functions for each alert type or processing step.


All Functions Exceeding Thresholds

File Lines Cyclomatic Cognitive Length Exceeds
fix-duplicate-project-ids.ts 39-223 27 🔴 25 🔴 185 🔴 All metrics
create-cors-alerts.ts 64-178 13 ⚠️ 9 ✅ 115 🔴 Cyclomatic, Length
useFilterPersistence.ts 57-122 7 ✅ 15 ⚠️ 66 ⚠️ Length
useRssFeed.ts 255-368 9 ✅ 12 ✅ 114 🔴 Length
verify-uuid-v7.ts 13-100 14 🔴 6 ✅ 88 🔴 Cyclomatic, Length
rateLimiter.ts 162-228 8 ✅ 5 ✅ 67 ⚠️ Length
fileSizeLimit.ts 49-125 4 ✅ 4 ✅ 77 ⚠️ Length
sync-github-to-inventory.ts 423-480 5 ✅ 2 ✅ 58 ⚠️ Length

2. Code Smells Detection

Summary

Severity Count Percentage
🔴 High 3 0.2%
⚠️ Medium 6 0.3%
ℹ️ Low 1,860 99.5%
Total 1,869 100%

High Severity Smells (3)

1-2. Very Large Classes (2 instances)

  • Class 1: 590 lines (197% over 300-line threshold) ❌
  • Class 2: 650 lines (217% over 300-line threshold) ❌

Recommendation: HIGH PRIORITY - Refactor these large classes into smaller, focused classes following Single Responsibility Principle.


3. Class with Too Many Methods

  • Methods: 49 (245% over 20-method threshold) ❌

Recommendation: HIGH PRIORITY - This class has too many responsibilities. Consider:

  • Extract groups of related methods into separate classes
  • Use composition over inheritance
  • Follow Interface Segregation Principle

Medium Severity Smells (6)

All 6 medium severity smells are large classes slightly over the 300-line threshold:

  • 337 lines (112% of threshold)
  • 313 lines (104% of threshold)
  • 363 lines (121% of threshold)
  • 309 lines (103% of threshold)
  • 337 lines (112% of threshold)
  • 399 lines (133% of threshold)

Recommendation: MEDIUM PRIORITY - Review these classes for potential refactoring opportunities. Look for:

  • Groups of related methods that could be extracted
  • Utility methods that could become standalone functions
  • State that could be encapsulated in separate classes

Low Severity Smells (1,860)

Type: Magic Numbers

Count: 1,860 instances

Description: Hardcoded numeric constants that lack clear meaning.

Examples of magic numbers:

// Bad
if (response.status === 200) { ... }
setTimeout(() => {...}, 5000);
const pageSize = 10;

// Good
const HTTP_OK = 200;
if (response.status === HTTP_OK) { ... }

const DEFAULT_TIMEOUT_MS = 5000;
setTimeout(() => {...}, DEFAULT_TIMEOUT_MS);

const DEFAULT_PAGE_SIZE = 10;
const pageSize = DEFAULT_PAGE_SIZE;

Recommendation: LOW PRIORITY - While there are many magic numbers, this is common and typically low impact. Consider:

  • Creating constants for frequently-used values
  • Focusing on business-critical numeric values first
  • Using configuration files for thresholds and limits

3. Security Analysis

Summary

EXCELLENT - No security vulnerabilities detected

The comprehensive security scan checked for:

  • ❌ SQL Injection (f-strings, .format(), concatenation) - None found
  • ❌ XSS (innerHTML, document.write with user input) - None found
  • ❌ Command Injection (os.system, subprocess with shell=True) - None found
  • ❌ Hardcoded Secrets (API keys, tokens, passwords) - None found
  • ❌ Insecure Cryptography (MD5, SHA-1) - None found

Scan Coverage:

  • Language: TypeScript/JavaScript
  • Files scanned: 303 (excluding node_modules, build, dist)
  • Issue types: All critical vulnerability types
  • Severity threshold: Low (comprehensive scan)
  • Max issues to report: 200

Conclusion: The AnalyticsBot codebase demonstrates good security practices with no detectable vulnerabilities using static analysis patterns.


4. Recommendations by Priority

🔴 HIGH PRIORITY (3 items)

  1. Refactor fix-duplicate-project-ids.ts (lines 39-223)
    • Break 185-line function into 4-6 smaller functions
    • Reduce cyclomatic complexity from 27 to <10 per function
    • Target: 20-50 lines per extracted function
    • Impact: Significantly improve maintainability and testability
  2. Refactor the 590-line class
    • Identify logical groupings of functionality
    • Extract 3-5 smaller classes
    • Target: <300 lines per class
    • Impact: Better adherence to Single Responsibility Principle
  3. Refactor the 650-line class
    • Similar approach to #2
    • Look for cohesive subdomains
    • Impact: Improved code organization and maintainability

⚠️ MEDIUM PRIORITY (9 items)

  1. Refactor create-cors-alerts.ts (lines 64-178)
    • Split 115-line function into smaller functions
    • Extract alert creation logic per type
    • Target: <50 lines per function
  2. Simplify useFilterPersistence.ts hook
    • Extract persistence logic into helper functions
    • Reduce cognitive complexity from 15 to <10
  3. Refactor the class with 49 methods
    • Group related methods
    • Extract 2-3 specialized classes
    • Target: <20 methods per class

7-12. Review 6 medium-sized classes (309-399 lines)

  • Evaluate for refactoring opportunities
  • Not urgent but should be on refactoring roadmap

ℹ️ LOW PRIORITY (4 items)

  1. Extract constants for verify-uuid-v7.ts
    • Function is long (88 lines) but relatively simple
    • Create named constants for validation thresholds
  2. Extract constants for useRssFeed.ts
    • 114-line function could be improved
    • Consider splitting fetch/parse/transform logic
  3. Create constants for common magic numbers
    • Focus on business-critical values first
    • HTTP status codes, timeouts, page sizes
    • ~50-100 constants would cover most important cases
  4. Remaining 1,800+ magic numbers
    • Address opportunistically during feature work
    • Not worth a dedicated refactoring effort

5. Code Quality Metrics

Complexity Distribution

Based on the 36 functions analyzed:

  • Excellent (cyclomatic <5): ~72% of functions ✅
  • Good (cyclomatic 5-10): ~14% of functions ✅
  • Needs Attention (cyclomatic 11-15): ~8% of functions ⚠️
  • Problematic (cyclomatic >15): ~6% of functions ❌

Maintainability Index

Overall Assessment: GOOD ⭐⭐⭐⭐ (4/5 stars)

Strengths:

  • Low average complexity (4.6 cyclomatic, 3.5 cognitive)
  • No critical security issues
  • Good separation of concerns in most modules
  • Reasonable file organization

Weaknesses:

  • A few very complex functions that need refactoring
  • Some large classes that violate SRP
  • High number of magic numbers (though mostly low impact)

6. Testing Coverage Recommendations

Based on complexity analysis, prioritize testing for:

  1. fix-duplicate-project-ids.ts - Most complex function, highest risk
  2. create-cors-alerts.ts - High cyclomatic complexity
  3. verify-uuid-v7.ts - High cyclomatic complexity
  4. useFilterPersistence.ts - High cognitive complexity
  5. useRssFeed.ts - Long function with moderate complexity

Recommendation: Aim for 80%+ coverage on these high-complexity functions.
