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.

The most advanced full-fledged SGF viewer and editor on iOS devices, seamlessly integrated with the web to support downloading of unlimited and most fresh professional go games, with a clean and simple user interface. + Deep integration with the professional go database from go4go.net so that you can access latest professional games by just a tap from go4go's rich resources, and search the desired games from the database by criteria like player names and tournaments, etc. + Clean and simple UI built on top of the deep technologies and elegant iOS platform. You can replay games in normal plain flat board with color or black/white mode, 3D perspective view, or browse the game like reading a real book. Even you can view the game with real 3D go ban model through Argument Reality technologies (available for devices running iOS 11+). + Web integration goes beyond browsing go4go database to support downloading games from any web site with SGF links. You can use the in-app web browser to view a web site with SGF resources and download them into your device with a tap on the link. Even with running games which are updated in remote server from time to time can be downloaded and updated with pull down gesture. The in-app browser supports downloading games from links to a single SGF file, or a Zip/RAR archive. + Local games downloaded or created manually can be organized in groups. Games starred are kept in favorite page. Games deleted are protected by keeping them in trash folder until you decide to delete them permanently or restore them back. You can search games by user names or tournament names in local game resources. + Full SGF editing features for complex SGF games with variations and comments. You can also transform the games by flipping and rotating a game. Scoring an end game is provided. + Support AirPlay with a new board viewing scheme mirroring on big TV screens. + Including image recognition for user to generate SGF from images. Work for computer generated board images with 90%+ recognition rate. Support real life board photos from 1.8.0 version. But don't buy if only for this feature as it is not the most advanced image recognizer now (was in its early release). + Many features hidden in small details. You can play with the settings and find many handy small shining things. The nearly 10-year old app was updated and polished continuously, with inputs from various go fans all over the world. Let's keep the go app standard high together.

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.
