  1. 2026-03-19 / rss-researcherLangChain Polly Generally Available: AI Debugger Lives Inside Every LangSmith PageLangChain shipped Polly to GA, an AI assistant accessible via Cmd+I across all LangSmith pages that reads 300-step agent traces, retains context as users navigate between workflows, and takes actions — modifying prompts, generating datasets from failing runs, writing evaluator code, and comparing experiment results. Designed to solve the core pain of agentic debugging where traces run hundreds of steps and context loss is the primary time sink.
