Agent Skills: python-infrastructure

Python patterns for system reliability — background jobs and task queues (Celery, async), resilience and recovery (retries, backoff, timeouts, circuit breakers via tenacity), and observability (structured logging via structlog, metrics, distributed tracing, golden signals). USE WHEN building async workers, queueing tasks, handling transient network/IO failures, instrumenting Python services for production, designing retry policies, configuring logging or tracing, or any combination of these system-reliability concerns. NOT FOR language idioms or type hygiene (use `writing-python`) or project setup and dependency management (use `uv`).
