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
Come and get it!!... This dinner bell is more than just a dining invitation. Shake your device to ring the bell. The clanger moves just like a real bell each time you shake your phone, allowing you to control the speed of the ringing. This hand bell truly sounds like a real bell, but you won't hear just the clang of a bell. There are over 25 great sounds to choose from: Bells- bicycle, cow, dinner, door, school, tiny, and triangle Chimes - electric, musical, and wind Clocks - alarm and grandfather Drums - bongo, crash cymbal, drum roll, percussion, and snare Funny - bubbles, glass break, gong, kazoo and man scream Horns - clown, diesel, and fog Whistles - referee, sexy, and spinning Custom - Record up to 10 sounds of your own What makes this app unique is that you can change the pitch of every sound and the bounciness of the clanger. So, you don't have to settle for the default sounds of other apps - YOU CAN MAKE THEM YOUR OWN PERSONALIZED SOUNDS! Where ever you go, you can call in the troops or just have fun with these sounds on your iPhone or iPad!

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.
