Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Carby plans your week of dinners around the things that actually matter: where you shop, what you want to spend, the food you like, and what's in your kitchen. Answer a few quick questions and Carby builds a full Monday–Friday dinner plan with a costed, ready-to-shop grocery list — no more staring into the fridge at 6pm. WHY YOU'LL LOVE IT • Shop your store — Walmart, Kroger, Target, Aldi, Costco, Safeway, Publix, Whole Foods, or Trader Joe's. Prices adjust to where you actually shop. • Stay on budget — set a weekly dinner budget and Carby keeps the whole plan under it. See your estimated total before you spend a cent. • Live prices — pull real, current prices for your store so your grocery total reflects today, not a guess. • Cook what you like — choose vibes like Quick & Easy, High Protein, Healthy Comfort, Family Favorites, or Takeout Faves. • Your kitchen, your way — only get recipes you can actually make with the appliances you own (microwave, air fryer, oven, stove, slow cooker). • Feeds your household — scale every recipe and the shopping list to 1, 2, 4, or 6 people. • Smart grocery list — ingredients across the week are combined, grouped by aisle, and check off as you shop. Mark what's already in your pantry and it drops off the list. • Cooking mode — a clean, step-by-step, full-screen guide with built-in timers. • Save & revisit — favorite recipes, save plans, and reopen any week. Dietary needs covered: vegan, vegetarian, gluten-free, dairy-free, and nut-free. Carby turns "what's for dinner?" into a 60-second decision — and a grocery trip you've already planned.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
