Generate Codebook Skill

Turn a raw tabular dataset into a structured, citable data dictionary (codebook). This is the generator side of the dictionary-first workflow: it produces the artifact that /define-variables and dictionary-first QC later consume. Distributions, types, and missingness are observable and the bundled script profiles them; the meaning of a coded value (fatty_liver_grade = 0) is not observable from the data and lives only in the authoritative data dictionary. You generate code and review output — you do not invent the meaning of coded values.

Deterministic Script

Run the bundled profiler rather than describing columns from memory:

python "${CLAUDE_SKILL_DIR}/scripts/generate_codebook.py" data.csv --out-dir .
