Test without RUNTIME_ENV_PATH -```bash -unset RUNTIME_ENV_PATH -python main.py # Should not crash -``` - -### 2. Test Python 3.8 compatibility -```bash -python3.8 -c "import tools.price_tools" # Should succeed -``` - -### 3. Test missing OpenAI API key -```bash -unset OPENAI_API_KEY -python main.py # Should show helpful error message -``` - -### 4. Test MCP services down -```bash -# Don't run agent_tools/start_mcp_services.py -python main.py # Should show helpful error message suggesting to start services -``` - ---- - -## Files Modified -1. ✅ `tools/general_tools.py` - 3 fixes -2. ✅ `tools/price_tools.py` - 2 fixes -3. ✅ `agent/base_agent/base_agent.py` - 1 fix - -## Impact -- **Before:** Application would crash with cryptic error messages -- **After:** Application provides clear, actionable error messages and gracefully handles missing configurations - -## Severity -All fixes address **critical** runtime issues that would prevent the application from starting or operating correctly.
