## 🔧 Issues Found & Fixed
### Issue 1: Invalid Format Error Handling
- **Problem:** Invalid format parameter returned plain text instead of JSON
- **Root Cause:** Logic error in `src/mcp_server.py:220` - checking `if format == "json"` when format was already invalid
- **Fix Applied:** Always return JSON for invalid format errors for consistency
- **Files Modified:**
- `src/mcp_server.py:218-221` (consult_codex function)
- `src/mcp_server.py:333-336` (consult_codex_with_stdin function)
- **Status:** ✅ FIXED & VERIFIED
