About

Cost Analysis

Reads the current menu and inventory files to calculate pour cost per drink, category COGS, and margin percentages. Flags items with high pour costs (>30%) or low margins (<$8).

When to Use

  • When reviewing menu pricing decisions
  • Before adjusting prices on cocktails or spirits
  • Monthly cost analysis for the bar

Procedure

python -m skills.cost_analysis --format json
python -m skills.cost_analysis --format json --category cocktails

Optional: --category all|beer|spirits|wine|cocktails (defaults to all).

Exit Codes

| Code | Meaning | |------|---------| | 0 | OK, all margins healthy | | 1 | Warnings: high pour cost or low margin items | | 2 | Config error | | 3 | Data error | | 10 | Unexpected error |

Verification

  • Exit code is 0 or 1
  • stdout is valid JSON (with --format json)
  • data.items contains analyzed menu items with cost/margin data
