- ID: docker-file-operations
- Severity: LOW
- Languages: Dockerfile
- Frameworks: docker

{issue_type}. Use specific paths (e.g., COPY src/ ./src/) or create a .dockerignore file to exclude sensitive files and build artifacts.

Use COPY instead of ADD for local files.

```dockerfile
COPY package*.json ./
COPY src/ ./src/
```
