A product spec, screen plans, and build steps for your coding agent.

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.

Alerta de Sismos, del Ministerio de Medio Ambiente y Recursos Naturales de El Salvador, es una app móvil que notifica a los usuarios los sismos que pueden ser sentidos y brindar, en el mejor de los casos, alerta temprana y que el usuario tenga tiempo para realizar la acción de Protegerse. Efectivo solo a distancias entre unos 50 a 150 km. Más cerca no hay tiempo para alertar y más lejos aunque el sismo pueda ser sentido no causará daños tan importantes como para que se declare una alerta. Es una aplicación gratuita y un servicio que brinda el Ministerio de Medio Ambiente y Recursos Naturales del El Salvador como complemento al trabajo de diseminación de información que realiza. Es un sistema completamente automatizado que enlaza múltiples instrumentos y algoritmos y por lo tanto es susceptible a fallas técnicas. La app brinda tres tipos de alertas: Roja, Naranja y Verde. La Alerta Roja es aquella que significa que el sismo puede ser sentido con intensidad en la Escala de Mercalli Modificada (IMM) mayor o igual a V y que el usuario tiene algunos segundos para tomar la acción de Agacharse, Protegerse y Esperar. Se notifica con comando de VOZ y vibración. La Alerta Naranja es aquella que significa que el sismo puede ser sentido con intensidad mayor o igual a III pero menor a V. Se notifica con SONIDO y vibración. La Alerta Verde es aquella que significa que el sismo puede ser sentido con intensidad menor a III. Se notifica de manera silenciosa. Para cada evento existe la opción de reportar la experiencia de lo que percibió o sintió durante el sismo.

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.
