THE THREE DISCIPLINES AROUND THE MODEL

PRACTICE LAB CONNECTION The Resume Review Agent is a convenient place to see all three disciplines at once. The wording of the review instructions is prompt engineering. Choosing which resume text, which job posting excerpt, and which earlier results to show at each step is context engineering. The loop, the file-reading tool, the limits on steps, and the logging are harness engineering. As you read the lab files later, try labeling each part with the discipline it belongs to. Then use the first prompt below to triage a failure from a lab run log, and the second prompt to decide where to spend improvement time.
