#### 📈 Workflow Improvements
##### Before Phase 2 (Vector Store Management Only)
```
User has files → [MANUAL UPLOAD TO OPENAI] → Use vector store tools
❌ Broken workflow - users had to manually upload files first
```
##### After Phase 2 (Complete Workflow)
```
User has files → file-upload → vector-store-file-add → Complete workflow
✅ Seamless end-to-end experience
```
##### Real-World Usage Examples
1. **Document Processing**: Upload PDFs → Add to vector store → Query documents
2. **Code Analysis**: Upload source files → Create vector store → Search codebase
3. **Knowledge Base**: Upload documentation → Build searchable knowledge base
4. **Content Management**: Upload articles → Organize in vector stores → Semantic search
5. **Bulk Processing**: Upload 470 PDF files → Batch add to vector store → Search entire collection
