+### CLI Smoke Tests
+
+1. Created test_cli_smoke.py with integration tests for the CLI commands
+2. Implemented tests that use temporary files to test CLI functionality
+3. Added tests for key CLI commands: health, show-config, scan-text, redact-text, replace-text, and list-entities
+4. Used the typer.testing.CliRunner to invoke CLI commands programmatically
+5. Applied the integration marker to all CLI smoke tests
+
+The CLI smoke tests verify that:
+- Basic CLI commands execute successfully
+- Text processing commands correctly handle PII in text files
+- Configuration and entity listing commands return expected information
