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.

Powerball Planner is a tool that uses historical drawing data to generate number sets through different algorithmic methods. Instead of pure random selection, the app applies several structured approaches (including frequency analysis and combined strategies) to produce sets of numbers based on past results. ### Key Features • Algorithmic Generation — Create sets of numbers using multiple methods derived from historical Powerball data. • Smart Blend — A combined approach that blends several algorithmic techniques. • Save & Track Plays — Store your generated sets so you can keep track of what you’ve played. • Historical Results — Browse recent winning numbers. • Fully Offline — Everything runs locally on your device. No internet connection is required. • No Accounts or Data Collection — The app does not collect personal information or require any login. • Home Screen Widget — View recent generations directly from your home screen. • Clean Interface — Designed for quick use before each draw. Powerball Planner is a planning and organization tool for players who prefer a structured, algorithmic method over random selection. All lotteries are games of chance. This app does not improve your odds of winning. Plan your plays. Track your tickets. Stay organized.

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.
