Generating… usually about a minute.
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.

FabFocus is everything you need to capture and create stunning portrait photos. And the best part is, you don’t need multiple cameras to do it! FabFocus works on all devices running iOS 12 and forward and uses advanced image recognition to detect people, and intelligently blurring the background, applying beautiful bokeh effects. ———— The Big 2.0 Update FabFocus 2.0 is a complete rewrite and redesign, with the goal of making it as fast and simple as possible to make stunning portraits. Every last detail has been considered and refined to streamline the experience. We hope you love it as much as we do. ———— Features FabFocus has a lot of different features. Here’s a quick overview. ———— Face Detection FabFocus will automatically detect faces in your photos, use a little computer magic to work out what’s in the foreground and then intelligently blur the background. If a photo contains depth information, that is used that for even faster performance. ———— Camera FabFocus has its own camera interface, that automatically configures itself for portrait capture on supported devices. ———— Editing Tools FabFocus has a whole bunch of tools to help you refine your portraits. • Adjust the amount of blur applied to the background • Chose the shape of bokeh (even set it to love hearts or stars!) • Change the brightness and saturation of the foreground and background independently. • You can also draw to refine the selection of what’s in the foreground, great for tricky situations, or creating portraits of a wide variety of subjects, like pets, plants and more! While editing, you can quickly undo and redo your adjustments, and there are buttons to share and save your photos right away. ———— Take your portraits to the next level with FabFocus ———— For support, please contact [email protected]

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.
