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
Introducing Layla, the groundbreaking personal AI that resides directly on your phone or device. No internet connection required, no censorship, complete privacy. No information leaves your device. Features: - General knowledge: ask Layla about anything under the sun, she will give you an informed response - Just chatting: Layla has many personalities you can choose; from cute to serious to bubbly to stoic, you can talk with her however you want - Memory: tell Layla about yourself, she'll remember you - Personalisation: you can create your own characters if none of our presets fit your style! - Voices: over 100+ different voices to choose from for your characters - Group chats: engage in conversation with multiple characters! - Agents: Layla supports programmable agents using Python - Custom AI: load custom GGUF models that fit your needs - Additional features available as free plugins: downloading different personalities, advanced settings Note: The app downloads a 4GB Large Language Model (LLM / brains of the AI) after the it starts for the first time. This is only needed once. This technology is VERY new, right now we only support the latest flagship phones (8GB+ RAM). If your phone does not meet the minimum requirements, you may experience degraded performance. We are working hard to bring Layla to more devices. DISCLAIMER: Layla is a generative language model. All her answers come from inputs you give her. This means her information may be inaccurate, outdated, or otherwise unsuitable for your situation. Layla is designed for purely entertainment purposes and her output should not be taken seriously. IMPORTANT: Local AI is an emerging technology and requires the latest flagship phones to run.

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.
