Golang Samber Hot

A skill for Go projects using samber/hot, the in-memory cache library that gives you nine eviction algorithms (LRU, LFU, W-TinyLFU, S3FIFO, ARC, and more), TTL with jitter, loader chains with singleflight deduplication, and Prometheus metrics. The skill knows how to pick algorithms based on access patterns, size caches from working-set estimates, and avoid the common mistakes like forgetting the janitor or enabling missing cache without config. Useful when you're adding caching to reduce backend pressure or latency, or when you need to tune an existing samber/hot setup. The skill pushes you to treat caching as a system design decision, not just a performance afterthought.
