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
OVER 1 MILLION JASON VALE APPS HAVE NOW BEEN SOLD! Super Blend Me! - Jason's first ever protein-based blending plan - is his quickest and easiest programme to date, and has been specifically developed for people who want to get super lean, super healthy, super-fast but don't want to clean a juicer (as you only need a blender!). Super Blend Me! has the perfect amount of macronutrients (protein, fat and carbohydrates) as well as a plethora of micronutrients (vitamins, minerals and phytonutrients) to satiate and sustain you whatever your lifestyle. Make the plan work for you and choose from either a 7, 10, 14 or full 21-day Super Blend Me plan, depending on your goals. All of the ingredients can be conveniently found in any major supermarket and are all recognisable, so no 'designer' berries that can only be found in an Amazonian rainforest, in this plan! The Super Blend Me! app brings the book to life and features everything you need to breeze through the plan, including: - The complete Super Blend Me! plan. - Delicious blend, energy ball & nut milk recipes. - Jason's 7 rules for success. - Jason's 7 tips for success. - Auto-generated shopping list function. - SOS coaching video from Jason. - 'Life After the Plan' audio from Jason. - Reminder alerts. ***** "I lost 12lbs in 10 days & 3% body fat!" JOANNE ***** Super Blend Me is the best diet I have ever been on." TAMARA M ABOUT JASON! Jason Vale, also known as the 'Juice Master', has sold over 6 million books, over 1 million apps, made a movie (Super Juice Me!), opened a few health retreats (www.juicemasterretreats.com) and been on a mission to Juice the World for over 20 years! "When it comes to juicing, there's only one man for the job." CAROL VORDERMAN "The King of Juicing." ALESHA DIXON “Jason Vale's approach is all about taking control of your health using common sense and logic. Always delivered with his unique humour and most importantly, easy to apply to your own life.” BEVERLY KNIGHT

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.

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.
