What problem does it solve?

This Skill guides you to implement structured logging with Structlog in HuleEdu services, enabling cross-service correlation, async-safe context propagation, and production-grade JSON output.

Core Features & Use Cases

• Structlog Configuration: Production (JSON) vs Development (colored console) setup
• Correlation Propagation: HTTP request → logs, Kafka events → logs, cross-service tracing
• Context Variables: Async-safe context binding with bind_contextvars
• Logger Creation: Service-specific logger instances
• Event Logging & Error Integration: Structured logging with correlation context in error handlers
• JSON Output: Production-ready JSON logs for Loki

Quick Start

Install and configure the logging utilities, create module loggers with create_service_logger, bind correlation context at request boundaries, emit logs with structured fields such as correlation_id and event_id, and ensure to clear contextvars at the end of processing.
