Generic Max-Supply Planning

Core

Execution order (mandatory): read scripts/model.py first, then decide relevant CSV files from the prompt, then read only those CSVs, then run baseline model.py, then copy to model_whatif.py, apply a targeted edit, and run model_whatif.py.
Source data and reference model: scripts/ for Python (data.py, model.py); scripts/data/ for CSV inputs. load_data(data_dir, num_periods) reads from that data directory; optional cost/backlog files are read separately if needed.

Workspace layout

Location	Contents
scripts/	Python: `data.py` (load_data), `model.py` (build/solve). Run from repository root (or your run directory) with `python scripts/model.py`.
scripts/data/	Required and optional CSV files (items, families, processes, supply, demand, etc.). All files from the data file map live here.

Using in the working directory

Do not modify the skill files. To run or change the model: (1) Copy skills/generic-max-supply/scripts/ into your run directory. (2) Edit only the copy. (3) Run from that run directory or repository root. Do not assume a fixed sandbox cwd.
