 This repo accompanies the **Interrupt 2026** workshop on aligning evals with LangSmith. It contains the datasets, judge prompts, and upload script for the workshop exercises (PII detection and hand-off accuracy).
 
+> **Note for live workshop attendees:** If you're attending the **live** Interrupt 2026 workshop in-person, **do not** follow the setup steps below. You'll be added to a separate workshop organization on the day, with the data in this repo pre-seeded for you. These instructions are intended only for those following the **pre-recorded** version of the workshop.
