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.

Vagusvit is your professional respiratory coach for strengthening the vagus nerve or rather your rest and digest nervous system. A permanently impaired vagus nerve contributes sooner or later to organic disorders. The easiest method to strengthen the vagus nerve is to practice a guided respiration under a special respiratory rhythm. Studies from around the world have proven that guided respiration is the ideal foundation for a gentle, fast, yet effective therapy that strengthens the autonomic nervous system and especially the vagus nerve. Life can move pretty fast at times, by enabling respiratory training, anywhere, anytime, you can conveniently help to prevent stress-related functional disorders, by increasing resistance to stress, and adding resilience to the body. Vagusvit enables you to breathe a healthy, vagus nerve stimulating respiratory rhythm. Vagusvit has been developed to work quickly and easily. With our easy to-use interface, our intuitive software is the ideal application accross all age groups. Vagusvit contains seven respiratory rhythms, including the rhythm of 6 breaths per minute. This rhythm has been integrated into the German National Healthcare Guidelines, as an inhalation of 4 seconds and an exhalation of 6 seconds has shown the greatest stimulation of the vagus nerve. Faster respiratory rhythms have been included for users not immediately able to breathe the standard rhythms, such as in COPD or asthma patients. This allows you to slowly approach the optimal rhythm. Additionally, two slower rhythms, for slower breathing users, allow the possibility of an even greater stimulation of the vagus nerve.

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.
