Operating standard for AI-assisted empirical and quantitative research: planning an analysis, acquiring and validating data, preparing time series, estimating statistical or econometric models, validating results, and reporting reproducibly. Use this skill WHENEVER the task involves analyzing a dataset, estimating a model, running a regression, building a forecast, doing causal inference (DiD, IV, RD, event study), profiling or cleaning data, feature engineering, or producing charts/tables from data — even if the user does not say "research" or "model" explicitly. If the work will read data and produce a number, figure, or table, follow this skill.
