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.

NICU medical staff oversee the care of our most precious and delicate new citizens. It is a profession that requires precise calculations, and unfortunately those calculations could be subject to human error. With the NICU Calculator app, errors will be greatly reduced. This will help NICU medical professionals better serve their patients. The NICU Calculator will also speed up daily work rounds, allowing more time for critical cases and patient care. This calculator was made and designed with the support of NICU staff who perform these calculations daily. The NICU Calculator performs the following calculations: Fluid Calculator: Exact fluid management is important for infants in the NICU and we created a calculator to help calculate total fluid, TPN, intralipid, and feeding rates. It also helps calculate TPN components such as GIR, dextrose percent, percent amino acids, protein, and intralipids. Extra function also allows you to take other fluids patient is taking into account such as feeds, medication drips, blood products, and medication/flushes. Calorie Intake: Knowing how many calories you are providing to a premature or ill newborn infant is important in regards to their growth and overall well-being. We created a calculator that allows you to determine how many calories you are providing in the TPN and feeds given. Glucose Infusion: This calculator allows you to determine the individual and total fluid volumes and glucose infusion rates (GIR) given to an infant when they are on individual or multiple infusion drips. Ca/Phos Calculator: This calculator allows you to determine the amount of elemental calcium and phosphorus given to a patient when using calcium and phosphorus salts. It also helps convert between commonly used units and determines ionized calcium: phosphorus ratio needed to determine appropriate dose for daily intake. Gestational Age: Allows you to calculate corrected gestational age and days of life using date and gestation at birth. Umbilical line/ETT: Calculates umbilical catheter size, umbilical artery catheter length, umbilical venous catheter length, intubation tube size, and intubation tube length based on the weight of the baby.

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.
