openrouter-caching-strategy

Quick Review

Well-structured skill with clear separation of concerns across multiple reference files. The description adequately covers caching strategies for OpenRouter (simple LRU to semantic similarity), and the modular organization (separate files for redis, semantic, in-memory caching, invalidation, errors, examples) indicates comprehensive task knowledge. Structure is excellent with a concise overview in SKILL.md and details delegated to reference files. Novelty is moderate: while caching LLM responses has cost benefits, the concept itself is fairly standard; the semantic caching aspect adds some complexity. The description could be slightly more explicit about which file to consult first for different caching approaches, but overall this is a solid, production-ready skill that would save tokens and implementation time for a CLI agent.
