Information at endpoint and service-method boundaries, Debug in deeper helpers, Warning before expected/recoverable failures (not-found, validation, agent tool errors), Error on caught exceptions. Serilog wraps the exception handler so request-completion logs report the resolved status code rather than the raw exception. Never logs prose bodies or the Anthropic API key.
