LangSmith Upgrades Tracing for Coding Agents
LangChain · x · 2026-07-15
LangChain announced that LangSmith now supports tracing and observability for coding agents like Cursor, Copilot, Pi, and OpenCode.
Key capabilities include:
- Full session observability without requiring additional instrumentation
- Identifying, grouping, and querying traces across different agents via stable keys
- Viewing complete run trees: turns, model calls, tools, and sub-agents
- Automatically displaying token usage and costs for each session
This acts as a major observability upgrade tailored for multi-agent and programming workflows.
