langsmith-tracing
LangSmith tracing and debugging setup for LLM applications. Configure observability, capture traces, and enable debugging for LangChain/LangGraph agents.
npx skills add a5c-ai/babysitter --skill langsmith-tracing --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# langsmith-tracing Configure LangSmith observability and tracing for LLM applications built with LangChain and LangGraph frameworks. ## Overview LangSmith is the managed observability suite by LangChain that provides: - Dashboards and alerting for LLM applications - Human-in-the-loop evaluation capabilities - Deep LangChain/LangGraph integration - Run Tree model for nested traces - MCP connectivity to Claude, VSCode ## Capabilities ### Core Tracing Setup - Initialize LangSmith client and API configuration - Configure project/workspace settings - Set up trace collection and sampling - Enable debug logging for agent execution ### Integration Patterns - LangChain chain tracing with automatic instrumentation - LangGraph workflow state tracking - Custom span creation for non-LangChain code - Parent-child trace relationships ### Debugging Features - Fetch execution traces for analysis - Query run history and metadata - Export traces for offline analysis - Compare runs across different versions ## Usage ### Environment Setup ```bash # Set required environment variables export LANGCHAIN_TRACING_V2=true export LANGCHAIN_API_KEY=<your-api-key> export LANGCHAIN_PROJECT=<project-name> ``` ###

What does the langsmith-tracing skill do?
LangSmith tracing and debugging setup for LLM applications. Configure observability, capture traces, and enable debugging for LangChain/LangGraph agents.
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill langsmith-tracing --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
