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
TheFlap is a throwback social app with that nostalgic mid-2010s vibe — a fast, playful feed where you post short updates ("flaps"), react, and keep up with your people. Post a flap with a photo and an animated mood, reply to friends, react, reflap the ones you love, and see who's online right now. No algorithm deciding what you see — just a clean, retro-flavored feed built around your community. Features: • Post flaps with photos and pick from dozens of animated mood faces • Reply, react with emojis, and reflap posts you love • See who's online and get notified when someone replies, likes, reflaps, or tags you • Verified badges, a live trending board, and a flapper-of-the-week spotlight • Add it to your home screen for a real-app feel Safety first: • Report any post or person in a couple of taps • Block anyone — you'll never see their content again • Delete your account and all your content anytime, right from the app • A real person reviews reports and removes violating content, normally within 24 hours TheFlap is a small, independent social app made by and for a tight-knit community. We don't sell your data. Terms of Use (EULA): https://weupallday.github.io/terms.html

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.

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.
