golang-samber-hot

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.

Quality

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a well-structured, actionable overview that defers depth to three clearly linked reference files and provides executable code plus concrete pitfalls. Minor conciseness and validation-loop gaps keep it just short of perfect.

Suggestions

Remove the persona paragraph and the 'This skill is not exhaustive...' sentence to tighten token efficiency.

Add an explicit validate→adjust feedback loop for capacity sizing (e.g., deploy, observe hit rate via Prometheus, then resize or switch algorithm) rather than leaving validation as an implicit best practice.

DimensionReasoningScore

Conciseness

Mostly lean with actionable tables and deferred detail, though the persona line and 'This skill is not exhaustive' throat-clearing add minor tokens that could be trimmed.

4 / 5

Actionability

Copy-paste-ready Go builder code, named algorithm constants, an install command, and specific method names (WithJitter, WithPrometheusMetrics, WithCopyOnRead) cover the common cases with executable guidance.

5 / 5

Workflow Clarity

The capacity-sizing section gives a clear numbered sequence and mistakes/best-practices provide guardrails, but there is no explicit validate→fix→retry feedback loop (only an implicit 'monitor hit rate to validate').

4 / 5

Progressive Disclosure

The body is an overview that signals three real one-level-deep references (algorithm-guide.md, production-patterns.md, api-reference.md, all present in ./references/) with clear markdown links and well-organized sections.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, comprehensive, and explicitly pairs a clear 'what' with multiple concrete 'when' triggers, anchored to a named library and import path. It is a strong, low-conflict trigger description.

DimensionReasoningScore

Specificity

Enumerates concrete capabilities by name — 9 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 — giving comprehensive, specific coverage rather than vague language.

5 / 5

Completeness

Explicitly answers both 'what' (in-memory caching with the listed feature set) and 'when' via concrete 'Apply when...' triggers covering adoption, import detection, and workload symptoms.

5 / 5

Trigger Term Quality

Natural terms users would say are well covered with synonyms — 'in-memory caching', 'Golang', 'reduce latency', 'backend pressure' — plus a strong import-path trigger ('when the codebase imports github.com/samber/hot').

5 / 5

Distinctiveness Conflict Risk

The samber/hot niche and import-path trigger make it clearly distinguishable from other caching skills with minimal conflict risk.
