Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
More than 900 magical places to explore in south west England from Daniel Start, author of Wild Swimming. Containing all the content from the "Wild Guide" (Wild Things Publishing £14.99, 2013), this app provides all you need to explore this beautiful and accessible region. This compendium of adventures features the best wild places to visit in Devon, Cornwall, Somerset and Dorset, with luscious places to eat and stay and ideas for weekend itineraries. The best secret beaches and wild swimming locations Amazing ancient woodlands and wildlife spectacles Top picnic places and wild flower meadows Lost ruins, hidden castles and sacred stones Caverns, caves, grottoes and follies Sunset hillforts, night walks and campfire camping Treehouses, yurts and gypsy caravans Best artisanal food, seasonal eating and traditional pubs Featuring stunning photos and engaging travel writing, this is the perfect book for those seeking new adventures with the family, or dreaming up the ultimate romantic weekend escape. NOTE: due to the large number of images and places the app is slow to load first time and may not work well (or crash) if many other apps are open in parallel. Please close other apps. You will find preloaded maps, photos, directions and travel writing to inspire and inform. Many of the land and water adventure locations comes with stunning photography. There are entries for pubs, campsites and attractions (usually without photos). If you need inspiration you can browse the app by slideshow, list, photo gallery and on an interactive map. Ask the app to find places close to you, or search using postcode, address, star rating, walk-in time, keywords or other features. You can share places on email and Facebook and save favourites 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.

BUILD KIT DIFFICULTY

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.
