test_run_agent.py (2 weak → 0, +13 assertions): - Session ID validated against actual YYYYMMDD_HHMMSS_hex format - API failure verifies error message propagation - Invalid JSON args verifies empty dict fallback + message structure - Context compression verifies final_response + completed flag - Invalid tool name retry verifies api_calls count - Invalid response verifies completed/failed/error structure test_model_tools.py (3 weak → 0): - Unknown tool error includes tool name in message - Exception returns dict with 'error' key + non-empty message - get_all_tool_names verifies both web_search AND terminal present test_approval.py (1 weak → 0, assert ratio 1.1 → 2.2): - Dangerous commands verify description content (delete, shell, drop, etc.) - Safe commands explicitly assert key AND desc are None - Pre/post condition checks for state management
