/meal-setup — Project Initialization

Create the Meal OS directory structure, seed data/config.yaml with household preferences, and seed data/canonical-ingredients.yaml with the core ingredient set.

Announce at start: "Setting up Meal OS project..."

Step 1: Check Current State

Check what already exists to avoid overwriting:

ls data/ 2>/dev/null && echo "data exists" || echo "data missing"
ls data/config.yaml 2>/dev/null && echo "config exists" || echo "config missing"
ls data/canonical-ingredients.yaml 2>/dev/null && echo "yaml exists" || echo "yaml missing"

Report findings to the user before proceeding.

Step 2: Create Directory Structure

Run:

mkdir -p data/recipes data/flyers data/meal-plans data/shopping-lists data/receipts/images/processed samples/flyers samples/meal-plans samples/shopping-lists samples/receipts

• data/recipes/ holds family recipes (local household data, gitignored)
• data/ directories are gitignored (local household data)
• samples/ directories hold sanitized examples safe to commit

Step 3: Create CLAUDE.md

If `CLAUDE.md` already exists at repo root: Skip this step — the user may have customized it.

If it does not exist, write CLAUDE.md at the project root:

# Meal OS

Personal meal planning system for a family.

## Household Configuration

User-specific constraints (diet, excluded ingredients, stores, thresholds) live in `data/config.yaml`.
All skills read this file at startup. See `samples/config.sample.yaml` for the format and defaults.

If `data/config.yaml` is missing, run `/meal-setup` to create it.

## Directory Structure

### data/ — local household data (gitignored)
- data/config.yaml — household preferences (diet, stores, thresholds)
- data/recipes/ — one markdown file per recipe (from /meal-add)
- data/canonical-ingredients.yaml — authoritative ingredient normalization reference
- data/flyers/ — parsed weekly store flyers (from /meal-flyer)
- data/meal-plans/ — weekly meal plans (from /meal-plan)
- data/shopping-lists/ — aisle-grouped shopping lists (from /meal-plan)
- data/receipts/ — receipt images, price history ledger, and OCR aliases (from /meal-receipt)

### samples/ — sanitized examples (tracked in git)
- samples/flyers/, samples/meal-plans/, samples/shopping-lists/, samples/receipts/

## Skills
- /meal-add — recipe intake and normalization
- /meal-flyer — store flyer parsing + loss leader detection
- /meal-plan — weekly meal planning + shopping list generation
- /meal-receipt — receipt OCR, price tracking, and alias learning

Step 4: Create config.yaml

If the file already exists: Ask — "data/config.yaml already exists. Overwrite with defaults (loses your customizations), or skip?"

If skip, go to Step 5.

If overwrite or creating new, ask the user these questions (use defaults if they say "use defaults"):

1. "What diet style? (e.g., mediterranean, whole30, paleo, keto, vegetarian, none)" — default: mediterranean
2. "Any ingredients to always exclude? (e.g., tuna, shellfish)" — default: none
3. "What grocery stores do you shop at?" — default: none (user must provide at least one)

Write data/config.yaml using the user's answers:

# Meal OS — Household Configuration
# Edit this file to customize your meal planning preferences.

diet: [user's diet choice]

excluded_ingredients:
  - [user's excluded items, or omit section if none]

stores:
  - [user's stores]

rotation_target:
  min: 12
  max: 15

ingredient_thresholds:
  target: 18
  warning: 25
  too_complex: 35

Step 5: Create canonical-ingredients.yaml

If the file already exists: Ask — "canonical-ingredients.yaml already exists. Overwrite with defaults (loses any custom entries), or skip?"

If skip, go to Step 6.

If overwrite or creating new, write data/canonical-ingredients.yaml:

# Meal OS — Canonical Ingredient Reference

# snake_case IDs are used in recipe files and flyer mappings.
