prompt-ab

claude

A/B harness for prompt-layer changes. Runs one fixed task through each prompt variant headlessly, measures the model noise floor first, counts what changed (visible text, reasoning, tics, em dashes, structure, reference codes) and renders every answer side by side with a prompt diff.
