## Known Issues & Limitations

### 1. Prompts Deferred
**Issue:** FastMCP prompt API changed in v2.13.0
**Status:** Prompts commented out, tools fully functional
**Impact:** Low - prompts are optional, tools work perfectly
**Resolution:** Will add once API confirmed

### 2. Dependency Conflicts (Expected)
**Issue:** Some packages have version conflicts with Gradio
**Status:** Warnings only, no functional impact
**Impact:** None - Gradio being removed
**Resolution:** Clean install recommended

### 3. Windows Path Issues
**Issue:** Windows pip sometimes has permission errors
**Status:** Resolved using `--user` flag
**Impact:** Installation only
**Resolution:** Use `pip install --user`
