How does the skill identify which prompts to optimize?

It utilizes Serena MCP to search for LLM clients and prompt construction points within the codebase; if unavailable, it performs a manual analysis using file system tools.

Will this skill change my LangGraph nodes or edges?

No, the skill is specifically designed to optimize the content and logic within existing nodes while strictly preserving the established graph structure and data flow.

Can this skill help with model cost reduction?

Yes, it incorporates optimization techniques such as temperature adjustment, model selection analysis, and prompt caching strategies to significantly reduce operational expenses.

What is the purpose of the .langgraph-master/fine-tune.md file?

This file acts as the primary configuration hub where optimization goals, evaluation criteria, and target metrics are defined to guide the iterative improvement process.

数据科学与机器学习

Optimizes LangGraph application performance through iterative prompt engineering and node-level logic refinements based on quantitative evaluation criteria.

关于

The LangGraph Fine-Tuning skill provides a systematic framework for improving the performance of existing agentic workflows by iteratively optimizing LLM prompts and processing logic within individual nodes. By utilizing Serena MCP for codebase analysis and maintaining strict graph structure integrity, it guides Claude through a rigorous cycle of baseline measurement, data-driven improvements, and re-evaluation. This skill is ideal for developers who need to enhance output quality, reduce error rates, or minimize token costs in established LangGraph applications without altering the underlying graph architecture or state schema.
