The release builds on LangSmith Fetch, the CLI tool LangChain launched in December 2025 that brought trace access directly into terminals and IDEs. That earlier tool already demonstrated significant efficiency gains - up to 96% context savings compared to traditional debugging methods for large traces. What skills actually do. Skills are essentially instruction sets that coding agents load dynamically when needed. Think of them as specialized knowledge packs. The key innovation here is progressive disclosure - agents only pull in relevant skills for their current task rather than loading everything upfront. This matters because previous research from LangChain showed that overloading agents with too many tools actually degrades their performance. By keeping skills modular and on-demand, agents stay focused. * Trace: Add tracing to existing code and query execution data * Dataset: Build example sets for testing * Evaluator: Run agents against those datasets and measure...
