`assert last_error is not None` was used as a runtime guard, but asserts are stripped when Python runs with -O (optimized mode). If the invariant were ever violated under -O, `last_error[0]` would raise an opaque TypeError instead of a meaningful error. Replace with an explicit if-check that raises ToolExecutionError with a clear diagnostic message if last_error is unexpectedly None. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
