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

CobbMeter is a medical tool designed to measure the Cobb angle, the kyphosis angle, and the sacral slope on vertical spine radiographs. It is intended to the Spinal care professional, and turns the iPhone into a professional measuring tool. " I designed CobbMeter with Regis Rigal as the professional tool I had always needed in my everyday practice in both Orthopedic Spine Surgery and Spinal non operative care. A tool that fits in the pocket in the very same device that I use to manage my busy schedule, that I can call immediately by pressing an icon, and which can be used on both regular radiographs or even a (vertical) computer screen to measure accurately the Cobb angle in spinal deformities, but also the kyphosis angle in spinal fractures and the sacral slope in degenerative and deformitic conditions. All that one has to do in using the device is align the side of the iPhone to the standard tracings we use routinely, and the position sensor built in the iPhone will do the rest. The precision of the device itself is 1/10th of a degree, far more precise than the precision of the measure as determined in everyday practice and the literature. Measures are logged for further use and may be sent by e-mail to the surgeon or staff for recording purposes, with the levels of the measured curve, type of curve and patient id or number. A calibration procedure was also implemented to accurately measure the angle with the horizontal plane as in the sacral slope. Through though the developpement, Regis has shown an extraordinary sense of patience and astounding programming skills so as to accurately provide a tool that fits the needs of the surgeon and the spine care provider to best treat the patients ; and I thank him for his efforts. I am very proud of releasing this small software in the community, and I hope it will facilitate a little bit the life of my dear colleagues and the patients. I thank the colleagues who gave me their kind advice on the software during its developpement and wish they will find it useful."

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.
