SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires langsmith>=0.2.0, and includes references (resource) components.

What problem does it solve?

LangSmith observability solves the challenge of debugging, evaluating, and monitoring LLM-based applications in production by collecting traces, evaluation results, and runtime metrics.

Core Features & Use Cases

  • Tracing: capture inputs, outputs, latency, and execution flow across prompts, chains, and agents
  • Evaluation pipelines: built-in evaluators and custom evaluators to measure correctness and quality
  • Datasets & monitoring: manage test sets, track metrics, and observe model behavior in production
  • LangChain integration: seamless tracing with LangChain components and workflows
  • Production readiness: diagnostics, alerting, and trace context propagation for reliable operations

Quick Start

Install the LangSmith SDK and enable tracing to begin automatically capturing runs in your application.

Frequently Asked Questions about langsmith-observability

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug performance and accuracy issues in production LLM deployments?▼

Monitor production LLM latency, errors, and cost by capturing traces and runtime metrics across LangSmith-enabled pipelines. Tracking these metrics across prompts, chains, and agents enables reliable operations and proactive diagnostics for your application.

Does LangSmith tracing work with LangChain components and workflows?▼

Evaluate LLM correctness and quality using built-in and custom evaluators within LangSmith evaluation pipelines. These evaluators measure model accuracy against managed datasets to track quality and correctness across your application.

What do I need to set up before capturing traces with the LangSmith SDK?▼

You need to install the LangSmith SDK version 0.2.0 or higher and enable tracing to begin automatically capturing runs. This setup allows your application to collect execution flow, inputs, outputs, and runtime metrics.

Can I manage test sets and track model behavior in production with LangSmith?▼

Yes, LangSmith supports managing datasets and monitoring to track metrics and observe model behavior in production. You can manage test sets, run evaluations, and apply diagnostics to ensure production readiness and alerting.
