Lesson 3: Building an evaluation set people actually ask

34 min read·13 Oct 2026
Module 11 · Lesson 3 · About 60 minutes · Needs: recall and hit rate in plain words (Module 4), the shared questions and query log (course-guide/06); no code from Lessons 1 and 2

The situation

Grace's pilot for her support agents starts on 2 November 2026 if the Module 11 gate passes, and a gate is only as good as its questions. Hollin Answers has 36 labelled questions, written by the course team. Grace's agents ask differently.

On 1 October 2026 an agent typed "cracked jar covered?" into Kwame's prototype, got the archived 2024 terms, gave a thumbs down and escalated. No labelled question looks like that. This lesson follows that query from the log into the evaluation set.

The rest of this course is yours to keep

This course is bought on its own, once, and stays readable afterwards, including the parts added to it later.
