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
Every face holds a story waiting to be told. Opalyne AI is an intelligent image creation app that transforms your portraits into cinematic art — placing you inside the world of independent film and crime thrillers, or letting time itself reshape the face you see in the mirror. Imagine stepping into the frame of an artistic indie film. Dusty roads, golden-hour light, the kind of quiet afternoon that makes everything feel bittersweet and free. Or picture your face rendered through the cold, shadowed lens of a crime thriller — where tension lives in every line and every glance carries the weight of something unsaid. But Opalyne AI goes beyond style. It lets you travel through time. See the face you wore in youth — unguarded, luminous, carrying a version of yourself the world had not yet changed. Or meet the elder you might one day become — features deepened by seasons, a stillness behind the eyes that only years can write. This is not a filter. It is a mirror to other lives, other timelines, other selves. Whether you are chasing a memory, exploring who you are, or simply curious about the face behind the face — Opalyne AI invites you to look again. Your story. Reimagined.

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.
