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.

The grocery list, optimised. Most digital shopping lists are static. They are simply paper moved to a screen. They do not account for the physical reality of your local supermarket: the aisles, the specific layout, and the unnecessary doubling back when you realise the eggs were three sections ago. Grocery Flow solves this by paying attention. How it works: There is no manual setup or tedious store mapping. You simply use the app. As you shop and tick items off, Grocery Flow learns the geographical sequence of your specific route through your specific store, shopping for your specific items. The next time you walk into that store, your list is not just a collection of items; it is a sorted itinerary. Features: Passive Route Learning: The app learns your shop’s layout as you use it. Store-Specific Memory: It distinguishes between different shops, remembering that your local Aldi is not laid out like the Tesco near work. Smart Import: Copy text from any source and the app will intelligently extract your items. Privacy by Design: Your data is yours. It stays on your device, not on a server. There is nothing uploaded to the cloud and no personal details required. No Subscriptions: There are no in-app purchases and no hidden fees. It is just a tool that works. I built this because I wanted a tool that respected my time. It is a simple solution to a universal inefficiency.

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.
