Troubleshooting Guide

Issue: Syntax Validation Fails

Symptoms:

• validation.syntax_valid: false
• Parse errors in output
• Missing imports

Root Causes:

1. Incomplete code generation
2. Version mismatch in syntax
3. Missing dependencies

Debug Checklist:

# 1. JavaScript/TypeScript
npx tsc --noEmit example.ts

# 2. Python
python -m py_compile example.py

# 3. Go
go build -o /dev/null example.go

Recovery Procedures:

1. Regenerate with structure.include_imports: true
2. Specify language version in context
3. Check for deprecated syntax

---

Issue: Missing Dependencies

Symptoms:

• Import errors when running
• dependencies array incomplete
• Wrong package versions

Debug Checklist:

# 1. Check dependencies exist
npm info package-name
pip show package-name
go list -m package-name

# 2. Verify versions
npm outdated
pip list --outdated
go list -u -m all

Recovery Procedures:

1. Update context.framework with version
2. Enable include_dependencies: true
3. Specify exact versions needed

---

Issue: Low Quality Scores

Symptoms:

• readability_score < 70
• documentation_score < 70
• Missing comments/docstrings

Recovery Procedures:

1. Enable include_comments: true
2. Set complexity: beginner for simpler code
3. Add quality.style_guide to enforce standards

Security Checks

Patterns to Detect

security_patterns:
  - pattern: "hardcoded_secret"
    regex: "(api[_-]?key|password|secret|token)\\s*=\\s*['\"][^'\"]+['\"]"
    severity: high
    message: "Avoid hardcoding secrets"

  - pattern: "eval_usage"
    regex: "\\beval\\s*\\("
    severity: high
    message: "Avoid using eval()"

  - pattern: "sql_injection"
    regex: "\\bexec\\s*\\(\\s*['\"].*\\+.*['\"]"
    severity: critical
    message: "Potential SQL injection"

  - pattern: "unsafe_deserialization"
    regex: "pickle\\.loads|yaml\\.load\\("
    severity: high
    message: "Use safe deserialization methods"

Best Practices

DO:

• Include all necessary imports
• Add meaningful comments explaining "why"
• Show expected output
• Include error handling
• Use environment variables for secrets
• Follow language conventions
• Add type hints/annotations

DON'T:

• Hardcode API keys or secrets
• Use deprecated methods
• Skip error handling in examples
• Write overly complex code
• Ignore security best practices
• Mix different code styles
