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.

ONE OF THE TELEGRAPH’S 500 MUST HAVE APPS – “THE PERFECT APP FOR SURVIVING OR AVOIDING RAIN” HOME & DRY IS GREAT FOR AVOIDING RAIN BY SEEING EXACTLY WHERE IT IS FALLING AND WHERE IT IS GOING NEXT LIVE LIGHTNING PLOTTING AND ALERTING OF NEARBY STRIKES Please note: Coverage of the Radar and Lightning strikes is for the UK and Ireland only. Coverage of the Forecast products in the app are for UK and Europe. When will it rain? When will it stop raining? Home and Dry provides the answer, immediately. The very latest rainfall radar information specific to your exact location - no need to search for your village, town or city - the app automatically locates you. 5 minute, 1km rain radar. The highest quality rain radar visualised for you quicker than any other app in the world! Real time lightning strike maps, alerting of nearby strikes and lightning risk forecast maps for the next three days ahead. Features include: • The very latest rain radar information animated at 5 minute intervals for the previous 2 hours overlaid on a fully zoomable map • Forecast rain radar for the next 3 hours ahead • Live Lightning maps for all strikes in the last 6 hours with audible alerting of new nearby strikes • Lightning push notifications of recent strikes in your area • Lightning risk forecast maps for the UK for the next three days • Easily share any of the content via, Twitter, Facebook, email, iMessage and even save to your Camera Roll. • UK and European forecast maps for the next 7 days (Rainfall, Temperature, Weather Symbols, Cloud Cover, Wind, and the Jet Stream) • Use the Maximum Wind Gust map for storm tracking. Map shows the latest hourly observed maximum gust speeds across the UK • Visible and infra-red satellite imagery for UK and Europe Radar Tutorial: • The radar shows exactly where and how hard it is raining across the UK • Use the observed radar and the forecast radar to understand exactly where the rain is, and where it is going relative to where you are. You should be able to see at what time it is either going to rain, or when it is going to stop raining • Check the radar before you need to go out so you can either adjust your timings to avoid getting soaked, or use the radar to be prepared and take an umbrella or coat with you • You can use Home and Dry for every trip outdoors, be it the school run, the commute to work, a walk in the park, watching football, going for a cycle, mowing the lawn, simply anything. Sometimes you can avoid the rain, sometimes you can’t. But at least with Home and Dry you can know when it is going to rain and plan accordingly. Warning - using the radar is highly addictive. Enjoy!

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.
