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.

Spreading the Spirit ... The Spirits' Book (Le Livre des Esprits in original French) is part of the Spiritist Codification, and is regarded as one of the five fundamental works of Spiritism. It was published by the French educator Allan Kardec on April 18, 1857. It was the first and remains the most important spiritist book, because it addresses in first hand all questions developed subsequently by Allan Kardec. The book is structured as a collection of questions regarding the origin of the spirits, the purpose of the life, the order of the universe, evil and good and the afterlife. Its answers, according to Kardec, were given to him by a group of spirits who identified themselves as "The Spirit of Truth", whom with he communicated with in several Spiritist sessions during the 1850s. Kardec, who considered himself an "organizer" rather than an author, grouped the questions and their answers by theme, occasionally including lengthier digressions the spirits had dictated to him on specific subjects, some signed by philosophers such as Augustine of Hippo and Thomas of Aquino and writers including Voltaire. This application is considered not only a book but an environmental study of Spiritualism.

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.
