Could you build this?
Partial The CLI wrapper, prompt pipeline, and statistical reporting can be vibe-coded, but implementing statistically sound calibration algorithms (e.g., Platt scaling, isotonic regression, ECE calculations) and dataset drift detection for structured LLM decision models requires machine learning domain knowledge.
What it would actually take: The tool requires a Python or TypeScript library implementing probability calibration methods (Platt scaling, temperature scaling, binning algorithms like Expected Calibration Error) comparing smaller typed models to an LLM evaluator. The hard part is mathematically robust confidence calibration, confidence interval estimation under distribution shift, and handling multi-class/structured schema outputs. It requires an applied machine learning practitioner with knowledge of uncertainty quantification.
