## Troubleshooting

### Common Issues and Solutions

#### 🔍 **"Git Repository Not Found"**
```bash
# Verify you're in a git repository
git status

# Initialize git if needed
git init

# Or specify repository path explicitly
ai-code-buddy --cli /path/to/your/repo
```

#### 🌿 **"Branch Not Found"**
```bash
# List available branches
git branch -a

# Use correct branch names (check remote branches)
ai-code-buddy --cli --source origin/main --target feature-branch

# For new repositories with default branch
ai-code-buddy --cli --source HEAD~1 --target HEAD
```

#### 📂 **"No Issues Found"**
This usually indicates:

- 🎯 No differences between specified branches
- 🚫 All files excluded by filter patterns
- 📁 Analysis limited to supported file types

**Solutions:**
```bash
# Check what files are being analyzed
ai-code-buddy --cli --verbose

# Broaden file inclusion
ai-code-buddy --cli --include "**/*"

# Check different branches
ai-code-buddy --cli --source HEAD~5 --target HEAD
```

#### ⚡ **Performance Issues with Large Repositories**
```bash
# Exclude build directories
ai-code-buddy --cli --exclude "target/**" --exclude "node_modules/**"

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

# Use more specific file patterns
ai-code-buddy --cli --include "src/**/*.rs"
```

#### 🖥️ **TUI Display Issues**
```bash
# If TUI doesn't display correctly, use CLI mode
ai-code-buddy --cli

# Check terminal compatibility

**💡 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:
```bash
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:
```bash
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:**
```bash
git clone https://github.com/edgarhsanchez/ai_code_buddy.git
cd ai_code_buddy
cargo build --release
./target/release/ai-code-buddy --help
```
