Replace all bare print() calls with proper logging using Python's standard logging module across the deerflow harness package. Changes across 8 files (16 print statements replaced): - agents/middlewares/clarification_middleware.py: use logger.info/debug - agents/middlewares/memory_middleware.py: use logger.debug - agents/middlewares/thread_data_middleware.py: use logger.debug - agents/middlewares/view_image_middleware.py: use logger.debug - agents/memory/queue.py: use logger.info/debug/warning/error - agents/lead_agent/prompt.py: use logger.error - skills/loader.py: use logger.warning - skills/parser.py: use logger.error Each file follows the established codebase convention: import logging logger = logging.getLogger(__name__) Log levels chosen based on message semantics: - debug: routine operational details (directory creation, timer resets) - info: significant state changes (memory queued, updates processed) - warning: recoverable issues (config load failures, skipped updates) - error: unexpected failures (parsing errors, memory update errors) Note: client.py is intentionally excluded as it uses print() for CLI output, which is the correct behavior for a command-line client.
