Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

Take a mind-blowing 3D tour of the Universe with Professor Brian Cox as your guide. The official Wonders app by arrangement with the BBC. AWARDED APPSTORE BEST OF 2012 US AND UK Now for iPhone and iPad 1 - with added features: cause the supernova explosion of Betelgeuse! Land on the surfaces of Mars, the Moon, Io and Enceledus! Journey up from the smallest particles, past the moons and planets of the Solar System, out through the Oort Cloud to the Milky Way, past our Local Stars and out to distant galaxies before arriving, finally, at the edge of the known Universe. On the way you will encounter the likes of seething Red Giants, beautiful Nebulae, pulsing Neutron stars and confront a daunting vision of a Black Hole sucking down a hapless star, all rendered in spectacular 3D. Professor Brian Cox provides mind-expanding insight in over 200 interactive articles pinned to the stars, planets, galaxies and other wonders modelled in extraordinary 3D, written in his accessible style and accompanied by two and a half hours of video from the BBC TV series Wonders of the Solar System and Wonders of the Universe. The app also includes hundreds of infographics and images of space objects supplied by astronomy experts, NASA and other space researchers. • Explore the entire Universe in 7 interlinked scales from sub-atomic to the edge of the known Universe, or take Brian's tours • Two-and-a-half hours of BBC video from the Wonders TV series (requires wifi) • 50+ spectacular 3D models of planets, moons, galaxies and nebulae to discover • Over 200 interactive articles by Brian telling the story of the Universe • Hundreds of beautiful images from around the cosmos • High resolution graphics optimised for the new iPad Reviews: “Few apps can match Wonders of the Universe.” New York Times “Wonders is hands down one of the best apps out there for the iPad.” The Next Web “One of the best educational apps to date.” Cnet.com “In a class of its own.” Daily Mail “The graphics and content make the experience well worth it.” Mashable “Astounding.” Popsci.com “Astonishing.” Appadvice.com “Stunningly produced.” MSN.com “The only app I’ve ever called perfect.” Imore.com “Have you ever wanted a grand tour of the universe…this is it, and you’ll love it.” Mac Observer “Professor Cox shows us the Cosmos as we have never seen it before - a place full of the most bizarre and powerful natural phenomena.” Sunday Express “It will entertain and delight.” Independent on Sunday “He bridges the gap between our childish sense of wonder and a rather more profound grasp of the scale of things.” Independent “Cox’s romantic, lyrical approach to astrophysics all adds up to an experience that feels less like homework and more like having a story told to you. A really good story too”.

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
