Generating… usually about a minute.
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.

Discover X-Vein, a revolutionary vein detection training support tool . X-Vein is designed specifically for medical professionals, providing an immersive, hands-on learning experience. The app uses the principle of visible light penetration and haemoglobin light absorption to visualise the blood vessels, in a similar principle as saturation monitoring. It presents an interactive interface where users can practice identifying veins in various skin layers, offering a more in-depth understanding of vein locating procedures. Whether you are a seasoned healthcare professional seeking to refine your skills or a medical student just starting, X-Vein offers a user-friendly platform to improve accuracy and confidence in vein detection. Elevate your vein-finding skills with X-Vein - the future of medical training at your fingertips. The research behind the technology is based on the penetration of different wavelengths into the human skin. different color wavelengths have different penetration depths and by subtracting visible wavelengths from others the image displayed can enhance the visibility of deeper visible light areas. The technology is similar to that of a saturation monitor which uses visible light to detect and measure pulse. *The Iphone/Ipad device has no functionality in the vein detection. Any visible light camera can perform the algorithm and generate a similar image. The iphone/Ipad camera sensors have no role in the vein detection process* **Remember - venous access is a 3D skill** This app can guide you on where to start but it can never replace experience and skill. Refer to the World Health Organization guidelines on drawing blood for more practical tips.

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.
