Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

The Nevasic programme is effective for a wide range of conditions- whether you suffer from pregnancy sickness, travel sickness or sickness related to excesses, medical conditions and prescribed drugs. Nevasic is a medical audio programme which stabilises the balance receptors in the inner ear in order to provide relief from nausea and sickness. Nevasic delivers precisely engineered stabilising audio pulses and frequencies, presented in a jacket of music, to make consumption easy. - - - - - - - - - - Clinical trial - Motion sickness The MRC Spatial Disorientation Group, Imperial College School of Medicine, London ran a full clinical trial under the branded of TravelWell. The trial proved conclusively that the programme is highly effective in combating the symptoms of nausea and vomiting associated with motion sickness. The report from the trial is lodged with PubMed and available via the National Library of Medicine (USA). - - - - - - - - - - NHS study - Morning sickness Nevasic was studied by the UK NHS under the branded name of MorningWell. The study was commissioned by; Mr M J Heard FRCOG Department of Obstetrics and Gynaecology Royal Hampshire County Hospital Winchester, UK.   Study Manager; Midwife Mrs Lynne Mayo - SRN, SCM, - Andover NHS Birth Centre. NHS research data. A National Health Service (NHS) Study showed 9 out of 10 pregnant women experienced a reduction or elimination of their symptoms of nausea & vomiting in morning sickness by using Nevasic branded as MorningWell. - - - - - - - - - - Clinical Trial - Cancer patients A clinical trial has been completed by Manchester University with mastectomy patients and the results were encouraging enough for a nationwide clinical trial to be requested by the UK institutes for research. This will be completed as soon as we can raise the required funding. - - - - - - - - - - Nevasic is a registered class 1 Medical Device in the UK and the USA. It is also registered by the Australian Medical Devices Listing Section (Conformity Assessment Branch) as an exempt product under the Therapeutic Goods Act. Reviews: Testimonial from USA customer: If all I have to do is commit to less than 30 minutes every 3-4 days to listen to soothing music in order to not be sick -- well, who wouldn't do that? The program definitely works, and I have told many of my friends about it so they won't have to suffer as I was before I found Nevasic. You were right in your initial email that it would take a few days to really work. Although I did have some relief the very first time I listened to it, it took a couple of days for the impact to really "stick." By the 4th day, though, I was able to not only eat to nourish the new life inside me, but I was able to get down on the floor to play w/ my 3 year old -- which I hadn't been able to do for several weeks. For that alone, I thank you!! (As would he, if he knew your program was the reason he was finally able to play with mommy again.) :o) I can't believe there isn't more information out there about the program. I only happened upon it while on google because I was desperate to find something - anything - that would at least alleviate my nausea, if not cure it. I'm glad I found it!! You guys should definitely advertise w/ OBGYNs in the States; there are a lot of women who need your program who don't even know that it's available. I will be mentioning it to my OB at my next appointment. Nevasic is amazing - I wish I had known about it during my last pregnancy, because it certainly would have been a lot more enjoyable for me! Thanks so much for an amazing product! I will also be submitting a glowing review on iTunes, which is where I purchased the program. Thanks again! Tara

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
