Plans a fair, rotating weekly chore schedule for a household: weighs each chore by minutes and frequency, respects capacity shares and "cannot do" limits, rotates jobs week to week, and reports each person's load against a fair target. Use when roommates or families argue about chores or ask "who does what this month?". Includes a stdlib Python planner with --self-test.
Scales a recipe by servings, a factor, or pan size (square, rectangle, round, loaf), converts between US cups and spoons, metric volume and grams with an ingredient density table, rounds to measurable amounts, and flags baking caveats such as fractional eggs, leavening at large factors, batter depth and bake time when the pan changes, tiny amounts, seasoning and cooking time. Includes a stdlib Python scaler with --self-test.
Splits shared costs for a group trip, house share, or event: equal, subset, weighted, or exact splits, mixed currencies with stated rates, and repayments already made, all in integer cents so totals match. Produces per-person balances and a short "who pays whom" list (at most one transfer fewer than people). Use when friends ask "who owes what?" after a trip or a shared house month. Includes a stdlib Python splitter with --self-test.
Builds a weekly meal plan with portion estimates and a grocery list rolled up by store section, then estimates total cost from unit prices you provide or simple defaults. Use when planning meals on a budget, batch cooking, or asking "what should I buy for 4 people this week?". Includes a stdlib Python cost estimator with --self-test.
Turns a list of meeting topics into a timed agenda with clock times, owners, and an outcome per item, checks it fits the slot with a buffer, flags late or rushed decisions, too many status updates, oversized items, and missing breaks, and writes the agenda to send. Includes a tested stdlib Python timeboxer with a fit mode.
