This skill provides a robust framework for managing and reducing Large Language Model (LLM) API costs in production environments. It introduces architectural patterns like complexity-based model routing—directing simpler tasks to cost-effective models like Claude Haiku while reserving Claude Sonnet for complex reasoning. By integrating immutable cost tracking, smart retry logic that avoids wasting tokens on permanent failures, and prompt caching for long system instructions, it allows developers to build high-performance AI agents that remain within strict budgetary constraints without sacrificing quality.
