Lab Tracker
Every lesson ends in something you did — a diagnosis, a real API call, a measurement. This page tracks them all.
Tick each lab off as you complete it (progress is saved in this browser; export it from the course home). Use the review-prompt box in each lesson to get your work reviewed before ticking the box.
- Scenario diagnoses Lesson 01 — three customer failures (invented policy clause, non-determinism, "forgotten" detail) each traced back to the next-token mechanism in your own words.
- First API call lab Lesson 02 — token counts for prose vs. JSON, a real call's usage meter read and priced in dollars, and time-to-first-token vs. total time measured on a streamed response.
- Prompt upgrades lab Lesson 03 — three prompt versions scored on five ticket extractions, plus your own v4 that beats v3, with a note on which technique fixed which failure.
- Structured extraction & tool hand-off lab Lesson 04 — schema-enforced extraction with zero parse failures, plus a traced tool_use hand-off (model requests, your code executes, grounded answer).
Why track these? The labs are where the course's ideas become skills you can
use in front of a customer. Each has a review prompt in its lesson — get the review, then
tick the box honestly.
