langchain-cost-tuning

Overall, the skill's footprint is coherent with its stated purpose of cost optimization for LangChain usage. It relies on internal, well-known libraries and standard data flows for token accounting, cost estimation, model tiering, caching, and budget enforcement. No hard requirements for mysterious external binaries or credential leakage are evident. Some production considerations to tighten include securing Redis endpoints, updating pricing data sources, and ensuring logs do not expose sensitive usage metrics.
