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.

You’ll learn how the mat exercise progressions prepare the body for similar exercises on the apparatus. Darien shows the link between mat work and the apparatus and gives detailed cues to explain why Joe’s mat exercises set the foundation for the entire Method. Part Three is Darien’s original Gold Talk series and is designed for those considering becoming a Pilates teacher or are already teaching and want to deepen their understanding of the why and how to teach the Pilates Method.

What our users say: “Darien is that rare teacher who flows with grace and beauty in her own Pilates practice, and who also teaches specifically, in detail how to do what she does. Her expertise is levels beyond that of any other teacher I’ve ever seen in person or online. And now, with her new app, it goes with me wherever I go!” — Diane R., Visual Artist “As a professional dressage rider I've been a longtime student of Darien Gold and have taken her private lessons for years. Since moving away two years ago, I've relied on the Darien Gold Pilates app and it has been just as effective as being with Darien in person. This app has significantly improved my fitness and riding, and I feel like she's right there with me during every session. I highly recommend this app to anyone looking to enhance their practice with the guidance of a master teacher.” — Allison Mathy, Dressage Horse trainer, rider and Gold Medalist "Pilates Mastery by Darien Gold is an extremely intuitive app that is silky smooth and easy to navigate. The app is broken into three categories, Practitioner, Teacher, and Mentor. All categories have videos that open with a written explanation that will help you progress with the Pilates Method whether you are a student or a teacher." — J. Vignola, Pilates civilian

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.
