In-memory caching in Golang using samber/hot — eviction algorithms (LRU, LFU, TinyLFU, W-TinyLFU, S3FIFO, ARC, TwoQueue, SIEVE, FIFO), TTL, cache loaders, sharding, stale-while-revalidate, missing key caching, and Prometheus metrics. Apply when using or adopting samber/hot, when the codebase imports github.com/samber/hot, or when the project repeatedly loads the same medium-to-low cardinality resources at high frequency and needs to reduce latency or backend pressure.

Questions

How do I install golang-samber-hot?: Download skills/golang-samber-hot/SKILL.md from the publisher, or copy the path and open the repository. PlugMCP lists the skill and does not host the file.
Where does golang-samber-hot live?: The publisher keeps it at https://github.com/samber/cc-skills-golang.
Which agents can use golang-samber-hot?: Claude, Cursor, and Codex can read a SKILL.md you add from the publisher's repository.

Algorithm	Constant	Best for	Avoid when
W-TinyLFU	`hot.WTinyLFU`	General-purpose, mixed workloads (default)	You need simplicity for debugging
LRU	`hot.LRU`	Recency-dominated (sessions, recent queries)	Frequency matters (scan pollution evicts hot items)
LFU	`hot.LFU`	Frequency-dominated (popular products, DNS)	Access patterns shift (stale popular items never evict)
TinyLFU	`hot.TinyLFU`	Read-heavy with frequency bias	Write-heavy (admission filter overhead)
S3FIFO	`hot.S3FIFO`	High throughput, scan-resistant	Small caches (<1000 items)
ARC	`hot.ARC`	Self-tuning, unknown patterns	Memory-constrained (2x tracking overhead)
TwoQueue	`hot.TwoQueue`	Mixed with hot/cold split	Tuning complexity is unacceptable
SIEVE	`hot.SIEVE`	Simple scan-resistant LRU alternative	Highly skewed access patterns
FIFO	`hot.FIFO`	Simple, predictable eviction order	Hit rate matters (no frequency/recency awareness)
