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.

Crystalzoa Create is a cosmic synthesizer of graphics in motion - an interactive, simulated visual experience for iPhone, iPad, Mac (Apple Silicon), and Vision Pro. Crystalzoa responds to movement, sound, and your touch. It includes 8 original music tacks, and 3 nature soundscapes, dozens of visual styles, and hundreds of tunable controls - giving you an infinite canvas of shimmering, evolving forms. Share your creations with high-resolution image capture, and flexible, production-quality movie creation, with 3D (stereoscopic) movie options. Crystalzoa remembers your favorite style combinations and images, but nothing is uploaded or shared unless you choose to share it. Advanced users can script animations, integrate MIDI input/output, remote-control other devices, or issue commands via Siri and Shortcuts. Crystalzoa even includes a built-in synthesizer for performance on the go. Features - Mesmerizing simulations of color, form, and sound transport you into the Crystalzoa universe. - Each of the 20 Crystalzoa Styles brings its own unique characteristics to the environment The different components interact to create unique images and animations. With over 200 detail controls, the combinations are virtually unlimited. - The Shuffle function and Auto-Shuffle mode reveal new possibilities for combining Crystalzoa to create fantastic effects. Auto-Shuffle creates captivating animations as the Crystalzoa periodically shift from one configuration to another. - Extensive controls for Auto-Shuffle let you customize the Shuffle experience, letting you tune out unwanted elements and enhance the screen-time of your boosted Crystalzoa. - AR mode brings the Crystalzoa into your home and surroundings using iPhone or iPad. - Record screen video and save high-res screenshots directly from within the app. - High quality Movie export options include: - Crystalzoa density multiplier brings in vastly more Crystalzoa to your scene * - Supersampled rendering * - Slow-mo and fast-mo timing - Video frame sizes up to 4K, and image sequence output up to 16K! * - Optional 3D movie output, in Spatial MV-HEVC format for VisionPro, as well as Full-Side-by-Side format. - Export with transparent backgrounds for use in Final Cut Pro, Pixelmator, and other tools. - Save and sync Favorites across devices via iCloud. - Share images easily with friends and family. - Import your own images and photos to influence the Crystalzoa experience. - Draw onscreen to leave glowing trails of Crystalzoa that interact with their environment. - Crystalzoa Create’s “Connect” feature lets you remote control Crystalzoa running on other devices on your local network.

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.
