Skill Claude CodeCodex
Establish a dumb baseline and an honest validation harness before any real model, so every later number means something.

lemma-causal
02Skill Claude CodeCodex
Rigor for causal questions and A/B tests (the effect of acting on X): confounding, post-treatment bias, valid control groups.

Skill Claude CodeCodex
Rigor for descriptive and diagnostic analytics (what happened and why): denominators, grain, and confounded slices, not model leakage.

lemma-eda
04Skill Claude CodeCodex
EDA kickoff for a fresh dataset: fixed opening scaffold (goal, imports, load, sanity), then chapters derived from the data; scan leakage, land a baseline.

Rigor for statistical inference (is the difference real): hypothesis tests, power, multiple comparisons, effect size over p-value.

Skill Claude CodeCodex
Audit a dataset or pipeline for the five leakages that inflate a metric: target, preprocessing, temporal, group, and sampling.

lemma-model
07Skill Claude CodeCodex
Final modeling once the baseline and feature set are locked: tune against validation, audit overfitting, touch the test set once, justify the complexity.

Review a notebook or analysis for data-science anti-patterns before it's trusted or shared.

Skill Claude CodeCodex
Rigor for clustering, dimensionality reduction, and anomaly detection: validity is stability under resampling, not a held-out score.
