Performance:

  • 2-3x faster for independent analyses
  • Code analyzer + Security checker run in parallel
  • Quality reviewer synthesizes results sequentially

Usage:

from utils.parallel_executor import run_agents_parallel

results = await run_agents_parallel(
    agents=agents,

Supported Languages:

  1. Python - Full support
  2. JavaScript - XSS, eval, innerHTML patterns
  3. TypeScript - Type safety checks
  4. Java - Command injection, reflection risks
  5. Go - SQL injection, command execution
  6. Rust - Unsafe blocks, unwrap() warnings

Security Patterns per Language:

  • Python: eval, exec, pickle, shell=True
  • JavaScript: eval, innerHTML, dangerouslySetInnerHTML
  • Java: Runtime.exec, File path traversal
  • Go: exec.Command, SQL injection
  • Rust: unsafe blocks, unwrap()

Usage:

from utils.multi_language import multi_language_analyzer

# Auto-detect
language = multi_language_analyzer.detect_language(code, filename)

# Analyze
vulnerabilities = multi_language_analyzer.scan_security(code, language)
