1. Load & Inspect: Read data, check shape and dtypes
2. Profile: Generate summary statistics
3. Quality Check: Missing values, duplicates, outliers
4. Visualize: Distribution plots, correlations
5. Report: Summarize findings

Tools Available

• Save intermediate results to scratch/
• Document findings in .planning/LEARNINGS.md
• Let errors surface naturally (no defensive coding)
