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.

Our Mulch Pro Estimator has the ability to calculate the amount of mulch required for your project in cubic yards and / or by bags. Our app calculates in BOTH imperial and metric units of measure. This app will allow you to calculate an unlimited number of areas. Our app also allows for extra. This is an important feature. Mulch, is sold by volume and is calculated in a uncompacted loose form. When you use it on your project, you'll most certainly want to pack it down some. The ability to include extra is a useful estimating procedure. Our app explains how to use this feature clearly. Include tax and material rates for a complete estimate. Add client info and you can email result to your office for review or directly to client for approval. Why Did We Develop This App: Too many folks, have a difficult time remembering industry standard formulas and conversions when it comes time to calculate materials. Mistakes can be made when: 1. Estimators forget to convert inches to feet when used in formulas. Imagine using 6" when the formula required you to convert the inch to feet first. You'd be way off on your estimate as the formula used 6" when in fact it should have been .5' 2. Estimators forget the constant numbers used to convert cubic feet to cubic yards. Many times it's hard to remember do I use 9 as a constant (when converting area calculations) or 27 (when converting volume calculations). Sometimes it becomes even more confusing, if you don't actually need to perform a conversion but you do. 3. Estimators forget to include a % of extra material to account for compaction factors or waste material. By not including the extra % required, you'll find yourself short of material on the job. Who Is This App For: Our Mulch Pro Estimator is a valuable tool for contractors, retailers, students and home owners alike. If you work with landscape materials you'll find that our app will aid you in calculating proper quantity takeoffs. You're task is to measure the required areas, our app will do the rest. Methods Used To Determine Answers: All industry acceptable methods of determining answers, equations and quantity takeoffs are used in calculating proper answers. Our app is unique as we allow you to adjust certain formulas with custom data. Don't worry we only allow this when needed and indicate so, in the calculator interface. As an example, when you're trying to find out how much mulch you require, we allow you to select which way you're going to purchase it. i.e. cubic yards or bags. As well, we allow you to input the depth of mulch, and the size of the bag!

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.
