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.

Stick and Split is a deceptively simple, addictive game. But what makes it so special is while they are playing it, children learn and practise their times tables, perhaps without even realising it. Research shows the more you think about something, the more likely you are to remember it. Most times tables games try to get children to answer simple questions like ‘what is 3 x 6?’ many, many times. The problem with this approach is it aims to get children to answer with the minimum of thought. So it’s no wonder children have to answer them thousands of times before they remember the answers. Many get bored and switch off before the memory sticks. Some children get anxious when they don’t know the answers, and research also shows feeling anxious is not a great way to make memories. Stick and Split has been carefully designed to encourage children to think much more about multiplication and division facts. There are no right or wrong answers, so it won’t induce anxiety. Instead they need to be constantly thinking what they need to do. The more they think, the more they remember. Reasons you’ll love Stick and Split: - Incredibly simple game play – you’ll learn how to play it in a minute - But with over 300 different levels, you’ll find there is so much to it - Covers up to 12x tables and division - Encourages children to think about what multiplication and division really mean, so they’re not just blindly “learning their times tables “ - Up to four children can have an account on the one device - Comes with advice for grown-ups supporting a child using the game - Stats show how much each child has played - An overview of all the levels shows you precisely what each child has done and enables them to jump to a level that’s suitable for them - A solid mathematical basis underpins the game - You won’t find a more cost-effective way to keep children occupied, thinking about numbers for hours

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.
