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.

Aplicación oficial de la letra del Himnario Evangélico Presbiteriano “Sólo a Dios la gloria” Iglesia Nacional Presbiteriana de México La Iglesia Nacional Presbiteriana de México, como parte de la Iglesia Uni- versal, se inserta en la historia de nuestro país desde hace más de un siglo y cuarto, y hoy está presente en casi todo el territorio nacional. Nuestra iglesia siempre ha observado fidelidad a las Sagradas Escrituras, conside- rándolas como su única regla infalible de fe y práctica de la vida cristiana, así como también a la rica tradición heredada de la reforma religiosa del siglo XVI, misma en la que se reincorporó al culto público, la alabanza del pueblo al Dios vivo y verdadero. Los presbiterianos de México hemos aprendido desde temprana edad que la alabanza se tributa a Dios quien merece toda honra, toda gloria y todo honor. Himnos como «Con cánticos, Señor», «Hoy te alabamos Dios de bondad», «Sólo a ti, Dios y Señor» y «Santo, santo, santo» son algu- nas de las joyas musicales de mayor arraigo entre el pueblo presbiteriano, mismas con las que se ha dado gloria a Dios y edificado a su Iglesia por más de cuatro décadas. La Biblia dice que: «Dios habita en medio de las alabanzas de su pueblo», Salmo 22.3. Es por eso que su iglesia siempre ha gozado de su presencia, toda vez que le canta y le exalta. En el pasado se usó música de origen sajón, consagrada para el canto congregacional, y la himnología protestante se enriqueció con las traducciones y com- posiciones originales de himnólogos mexicanos como Juan B. Cabrera, Eleazar Z. Pérez y Vicente Mendoza, por mencionar sólo algunos.

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.
