Sweet! CLI
Security & Best Practices

Secure Coding with AI: How Sweet! CLI Identifies and Fixes Vulnerabilities

Published on January 14, 2026 by Adam O'Reilly • 7 min read

In today's fast-paced development cycles, security often becomes an afterthought—until vulnerabilities are discovered in production. Manual code reviews and static analysis tools can only catch so much, leaving dangerous gaps in your application's defense.

Sweet! CLI transforms security from a manual checklist into an autonomous, continuous process. By understanding your codebase contextually, it identifies vulnerabilities, suggests immediate fixes, and implements security best practices—all without slowing down development.

The Security Gap in Modern Development

Developers face several security challenges:

  • Time pressure: Security practices are sacrificed to meet deadlines
  • Knowledge gaps: Not every developer is a security expert
  • Tool complexity: Security scanners produce overwhelming false positives
  • Changing threats: New vulnerabilities emerge faster than teams can adapt
  • Compliance requirements: Meeting standards like OWASP, SOC2, GDPR adds overhead

Sweet! CLI bridges these gaps by providing intelligent, context-aware security guidance directly in your workflow.

Autonomous Vulnerability Detection

Code Pattern Analysis

Sweet! CLI scans your code for common vulnerability patterns:

# Analyze a Python module for security issues
$ sweet "Analyze ./src/auth.py for security vulnerabilities"

🔍 Scanning auth.py: 450 lines, 12 functions
⚠️  Found 3 security issues:
  1. SQL injection risk in user_query() - line 45
  2. Hardcoded API key in config - line 89  
  3. Missing input validation in login() - line 123
✅ Generated fixes for all issues
📋 Suggested OWASP mitigation strategies

The system detects:

  • SQL Injection: Unparameterized queries, string concatenation
  • Cross-Site Scripting (XSS): Unsanitized user input in HTML output
  • Insecure Dependencies: Known CVEs in package manifests
  • Hardcoded Secrets: API keys, passwords, tokens in source code
  • Authentication Flaws: Weak password policies, missing MFA
  • Authorization Issues: Missing role checks, insecure direct object references

Dependency Security Scanning

Sweet! CLI automatically checks your dependencies for known vulnerabilities:

# Scan dependencies for security issues
$ sweet "Check package.json for vulnerable dependencies"

📦 Analyzing 142 dependencies
🔒 129 packages are up-to-date and secure
⚠️  13 packages have known vulnerabilities:
  - lodash (CVE-2023-XXXX) - prototype pollution
  - express (CVE-2024-XXXX) - path traversal
  - axios (CVE-2024-XXXX) - SSRF risk
🔄 Suggested updated versions with breaking change analysis

Intelligent Fix Generation

Context-Aware Remediation

Instead of generic warnings, Sweet! CLI provides specific, actionable fixes:

# Fix SQL injection vulnerability
$ sweet "Fix the SQL injection in user_query()"

🔍 Analyzing vulnerability context
📝 Understanding data flow: user_id → query → database
🛠️  Generating fix:
  - Replace string concatenation with parameterized queries
  - Add input validation for user_id
  - Include proper error handling
✅ Applied fix to auth.py lines 45-52
📚 Added security comments explaining the remediation

Fixes include:

  • Parameterized queries for database interactions
  • Input sanitization libraries for web applications
  • Environment variable configuration for secrets management
  • Security header implementations for web servers
  • Authentication middleware with best practices

Security Best Practices Implementation

Sweet! CLI doesn't just fix vulnerabilities—it proactively implements security measures:

# Implement security headers for Express.js
$ sweet "Add security headers to Express app"

🔍 Analyzing current Express configuration
📝 Implementing 7 essential security headers:
  - Content-Security-Policy (CSP)
  - X-Frame-Options (DENY)
  - X-Content-Type-Options (nosniff)
  - Referrer-Policy (strict-origin-when-cross-origin)
  - Permissions-Policy (camera=(), microphone=())
✅ Added helmet middleware with custom configuration
📋 Generated documentation for each header's purpose

Integration into Development Workflows

Pre-commit Security Checks

Sweet! CLI can be integrated into pre-commit hooks to catch vulnerabilities before they reach version control:

# Set up pre-commit security scanning
$ sweet "Create pre-commit hook for security scanning"

🔧 Setting up git pre-commit hook
📋 Configuring security checks:
  - Secret detection (AWS keys, tokens, passwords)
  - Vulnerability pattern scanning
  - Dependency security audit
✅ Created .pre-commit-config.yaml with security rules
📚 Added team documentation for bypass procedures

CI/CD Pipeline Integration

For continuous security, integrate Sweet! CLI into your CI/CD pipeline:

# Add security scanning to GitHub Actions
$ sweet "Create GitHub Action for security scanning"

🔧 Generating security-scan.yml workflow
📋 Configuring steps:
  1. Dependency vulnerability scan
  2. Static application security testing (SAST)
  3. Secret detection
  4. Security report generation
✅ Created .github/workflows/security-scan.yml
📊 Added security dashboard with trend analysis
