### What This Skill Does

This skill teaches intelligent caching strategies for OpenRouter responses:

- Exact match caching for identical prompts
- Semantic caching for similar queries
- Redis and in-memory cache implementations
- Cache TTL and invalidation strategies
- Cost savings measurement and reporting

### Technical Success Criteria

- Cache hit rate >60% for eligible requests
- Latency reduced by 80% for cached responses
- Proper cache invalidation preventing stale data

### Business Success Criteria

- 30-50% reduction in API costs
- Improved user experience with faster responses
- Reduced load on OpenRouter API
