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
Glance is a minimalist reading sanctuary designed to help you reclaim your attention. By using RSVP (Rapid Serial Visual Presentation) technology, Glance brings the text to you, one word at a time. Your eyes stay still, the world fades away, and your mind enters a state of total flow. In an age of endless scrolling and digital noise, Glance invites you to stop scanning and start experiencing. Read in peace, enjoy the moment, and let every sentence resonate. - Total Presence: By centering every word in a single focal point, Glance eliminates distractions and helps you stay deeply connected to the text. - Bring your own Library: Seamlessly import EPUB, MOBI books, or save Texts/URLs to enjoy your favorite articles offline. - Two Reading Modes: Switch between an overview mode similar to conventional reading applications and a speed reading mode - Make it your own: Pick your favorite font and colorscheme from many options We believe your reading time is sacred. That’s why Glance is built on a foundation of respect for your privacy and your pocketbook: No ads. No tracking. No subscriptions. No distractions. Ever. Just you, the words, and the moment.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
