Meal Planner Cart

Reads the meal planner's grocery manifest and fills your online grocery cart automatically using browser automation. Opens any grocery store website in Chrome, figures out how the site works without hardcoded instructions, searches for each ingredient, matches package sizes to recipe quantities, and handles out-of-stock items with a four-tier substitution fallback. Builds a store "playbook" after each session that remembers working search terms, site quirks, and approved substitutions so future runs are faster. Includes crash recovery that saves progress after every item, and generates a Gap Report documenting what was purchased, what was substituted, and which meals are affected. Supports eight countries with localized stores. Requires the meal-planner skill to generate the shopping data.
