Prompt Engineering · L3 Code

Implement structured, testable prompt templates and a basic prompt-evaluation harness.

Prompt template (parameterized)

Test cases (input -> expected property)

Runner (calls model on each case)

Scorer (checks property, aggregates)

Treating prompts as testable code rather than one-off strings.

Production prompt engineering means never hand-checking a single output and calling it done — it means writing a template, a set of test cases, and a scorer, exactly like software testing.
