How does it handle HTTP requests?

It provides patterns for instrumenting REST clients to automatically capture tracing data during external API calls.

What logging library does this skill use?

It uses the standard library log/slog for high-performance, structured JSON logging.

Does it support distributed tracing?

Yes, it leverages OpenTelemetry (OTel) to create and manage spans across services, repositories, and API clients.

Can I use this with AWS Lambda?

Yes, the skill includes specific implementation patterns for instrumenting Lambda handlers and managing the OpenTelemetry lifecycle.

When should I use different log levels?

Use INFO for normal operations, WARN for recoverable errors or degraded states, and ERROR for failures requiring immediate attention.
