Technical Questions

❓ Q: How accurate are the security vulnerability detections? 💡 A: Our OWASP-based analysis has a 95%+ accuracy rate for critical vulnerabilities with minimal false positives. The tool is designed for precision over recall to avoid alert fatigue.

❓ Q: Can I customize the analysis rules? 💡 A: Custom rule configuration is planned for Q2 2025. Currently, you can use --include and --exclude patterns to focus analysis on specific areas of your codebase.

❓ Q: Does it store or transmit my code anywhere? 💡 A: No! All analysis happens locally on your machine. No code is transmitted to external servers or stored anywhere except your local file system.

❓ Q: How do I integrate with my CI/CD pipeline? 💡 A: Use the --cli mode with --format json for programmatic integration. Check the CI/CD examples section for GitHub Actions, GitLab CI, and Jenkins templates.

Installation & Setup

❓ Q: Why am I getting "cargo: command not found"? 💡 A: You need to install Rust first:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env

❓ Q: How do I enable GPU acceleration? 💡 A: GPU acceleration is automatically detected during installation. For manual control:

# Force GPU features
cargo install ai-code-buddy --features gpu-metal  # Apple Silicon
cargo install ai-code-buddy --features gpu-cuda   # NVIDIA (Windows only)

❓ Q: Can I run this in Docker? 💡 A: Yes! See the Docker section for container usage examples. Perfect for CI/CD environments where you don't want to install Rust directly.

Performance & Optimization

❓ Q: Analysis is taking too long. How can I speed it up? 💡 A: Use these optimization strategies:

# Exclude large directories
ai-code-buddy --cli --exclude "target/**" --exclude "node_modules/**"

# Focus on recent changes only
ai-code-buddy --cli --source HEAD~10 --target HEAD

# Analyze specific languages
ai-code-buddy --cli --include "**/*.rs" --include "**/*.py"

❓ Q: Does it work well with large monorepos? 💡 A: Yes, but use filtering for best performance. The tool is optimized for repositories up to 100k files with proper exclusion patterns.

❓ Q: Can I run multiple analyses in parallel? 💡 A: Each ai-code-buddy instance analyzes files in parallel internally. For multiple repositories, run separate instances or use Docker Compose with multiple services.

Output & Reporting

❓ Q: What's the difference between output formats? 💡 A:

• summary: Human-readable overview (default)
• detailed: Complete issue list with descriptions
• json: Machine-readable for automation
• markdown: Perfect for documentation and reports

❓ Q: How do I filter issues by severity? 💡 A: Use jq with JSON output:

ai-code-buddy --cli --format json | jq '.issues[] | select(.severity == "Critical")'

❓ Q: Can I export reports to other tools? 💡 A: Yes! JSON output integrates with most tools. Markdown works great for GitHub Issues, and the format is compatible with many security platforms.

Troubleshooting

❓ Q: I'm seeing "GPU support requested but not compiled in" - what's wrong? 💡 A: This happens when GPU features weren't included during compilation. Reinstall with explicit features:

cargo install ai-code-buddy --features gpu-metal --force  # Apple Silicon

❓ Q: The tool isn't finding issues in my JavaScript code. Why? 💡 A: Make sure your files have proper extensions (.js, .ts, .jsx, .tsx) and aren't in excluded directories like node_modules/.

❓ Q: How do I report a false positive or false negative? 💡 A: Please open an issue on GitHub with:

• Code sample that triggered the false positive/negative
• Expected vs actual behavior
• Output with --verbose flag for debugging info

❓ Q: The analysis seems stuck. What should I do? 💡 A: Try these steps:

1. Use --verbose to see progress details
2. Check if you're analyzing very large files (>1MB)
3. Exclude binary files with --exclude "**/*.{jpg,png,pdf,zip}"
4. Kill and restart if truly stuck

Contributing & Development

❓ Q: How can I contribute new language support? 💡 A: We'd love your help! Check the Contributing section for guidelines on adding new language patterns. Start with the detect_language() function in ai_analyzer.rs.

❓ Q: Can I add custom security rules? 💡 A: Custom rules will be supported in Q2 2025. For now, you can modify the patterns in rule_based_analysis() and build from source.

❓ Q: How do I build from source for development? 💡 A:

Test Structure

Our testing strategy includes:

• Unit Tests: Core functionality testing for CLI arguments, Git operations, and theming
• Integration Tests: UI component testing using ratatui TestBackend
• Widget State Tests: Comprehensive testing of UI state management
• Property-Based Tests: Using proptest for robust input validation

Test Categories

1. Core Module Tests

   • test_args.rs: CLI argument parsing and validation (7 tests)
   • test_git.rs: Git repository operations and analysis (6 tests)
   • test_theme.rs: UI theming and styling (14 tests)
   • test_review.rs: Code review data structures (5 tests)

2. Widget State Tests

   • test_widget_states.rs: UI state management and transitions (21 tests)

3. Integration Tests

   • test_integration.rs: End-to-end UI component testing (7 tests)

Coverage Goals

We strive for high test coverage with the following priorities:

1. Critical Path Coverage: Core analysis and Git operations
2. UI Component Testing: Widget rendering and state management
3. Error Handling: Comprehensive error scenario testing
4. Edge Cases: Boundary conditions and unusual inputs

🚀 Quick Start for Contributors

1. Fork and Clone

   git clone https://github.com/your-username/ai_code_buddy.git
   cd ai_code_buddy

2. Development Setup

   # Install Rust if needed
   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   
   # Build the project
   cargo build
   
   # Run tests
   cargo test
   
   # Test the CLI
   cargo run -- --cli --help

3. Create a Feature Branch

   git checkout -b feature/amazing-feature

4. Make Your Changes and Test

   # Test your changes with the tool itself
   cargo run -- --cli --source main --target feature/amazing-feature
   
   # Run the full test suite
   cargo test --all-features
   
   # Check formatting and linting
   cargo fmt --check
   cargo clippy -- -D warnings

5. Commit and Push

   # Use conventional commit format for automated versioning
   ./commit.sh feat "add amazing feature"
   
   # Or commit manually following conventional format:
   git add .
   git commit -m "feat: add amazing feature"
   git push origin feature/amazing-feature

   📝 Conventional Commits & Automated Versioning

   This project uses Conventional Commits for automated semantic versioning and release management.

   Commit Message Format:

   type(scope): description
   
   [optional body]
   
   [optional footer]
   

   Types that trigger version bumps:

   • feat: → MINOR version bump (new features)
   • fix: → PATCH version bump (bug fixes)
   • feat!: or BREAKING CHANGE: → MAJOR version bump

   Quick commit examples:

   ./commit.sh feat "add user authentication system"
   ./commit.sh fix "resolve memory leak in analysis"
   ./commit.sh docs "update installation guide"

   Automated Release Process: When your PR is merged to main:

   1. ✅ Commits are analyzed for version bump type
   2. ✅ Cargo.toml version is automatically updated
   3. ✅ Git tag is created (e.g., v1.2.3)
   4. ✅ GitHub release is generated with changelog
   5. ✅ Package is published to crates.io

   📖 Full Guide: See CONVENTIONAL_COMMITS.md for detailed information.

6. Open a Pull Request

   • Ensure your PR description explains the changes
   • Include any relevant test files or examples
   • Reference any related issues
