Description
Open LangSmith traces from the runs table or by Jira ticket using your existing session. Trace Viewer helps developers open and inspect LangSmith traces directly from the runs table or by Jira ticket. It uses your existing signed-in LangSmith browser session, requests access only to the LangSmith origin you choose, and renders trace steps locally with filters, timing, token usage, messages, tool calls, and errors. An optional Trace Evals workflow lets you send the selected trace to a user-configured evaluation service, choose models, and open a live comparison arena. The eval service is configured separately and is used only when you explicitly start an evaluation. No API keys are bundled. Settings are stored locally in Chrome, and the extension contains no advertising or analytics code.
