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.

Oilist: the Artist in your pocket. Make Fine Art based on your pictures! "Oilist is an artist in your phone, one that you watch sketch, paint, and craft a unique version of a photo you’ve shot." - MacStories, May 2017 "App of the week: Oilist review - Hypnotic, engaging, with a longevity that escapes most filter apps, and with high-res output so you can use it to create real-world art." - Stuff Magazine, April 2017 Give Oilist an image, and it will automatically generate a genuine and unique work of art based on it. Painted for you in real time! Participate or spectate it's up to you, Oilist will delight! All saved at canvas-worthy 4k resolution. Oilist comes with 48 infinitely customizable styles; from photo-realist to impressionist, to abstract. Every style except for our photo-realist style offers three different levels of abstraction. Oilist is not a photo filter. Unlike most filter apps, Oilist will never generate the same results twice, and in fact, each brush stroke is unique. Instead of applying a fixed formula to an image as photo filters typically do, Oilist analyzes the supplied image using computer vision technology, then paints simulated paint particles that are applied using various brush strokes and techniques. At any time during the painting process, 4k resolution images may be captured as often as desired. When Oilist is painting, styles can be infinitely customized with 17 different presets (these were called Styles in previous versions of Oilist), 13 different painting moods, 15 different brushes, setting brush options such as the size and spacing, and by splashing paint with our exciting Chaos tool. Control paint gravity by tilting your device and brush angles by yawing (rotating) the device. Obtain new and exciting results by alternating settings with new settings painted on top of the previous settings. For instance, first, paint a layer using the Warm mood followed by a layer using the Cool mood. The use of large brushes tend to create more abstract artwork, and smaller brushes work best for high definition detail. Oilist will automatically provide smaller brush strokes and greater photo-realism to detected faces. Check out #oilist and follow us @3dtopo on Instagram and Twitter!

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.
