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.

This premium studio blends high‑fidelity 3D physics‑based fireworks with spatial 3D audio, allowing you to load any landscape or skyline and craft your own cinematic fireworks spectacle. With a fully randomized launch algorithm, no two firework sequences are ever the same. Every burst emerges at a unique timing, angle, and altitude, ensuring a constantly evolving display. Combined with manual firing, each show becomes a one‑of‑a‑kind live performance. ■ Key Features ● 27 Firework Types From classic Chrysanthemum, Peony, and Wabi-orange to Strobes, Silver Kamuro, Color‑Change shells, Palms, Bees, Thousand‑Blossoms, Banrai bursts, Hearts, Stars, and even 3D text fireworks. All modeled with realistic combustion, gravity, wind, and fading embers. ● 11 Choreographed Starmine Shows Golden cascades, pastel butterflies, traditional Wabi‑Sabi flames, lightning shock bursts, icy blue, aurora‑style, and rock‑themed flame shows. ● Intuitive Custom Controls Adjust star size, sound delay, 3D surround, and depth‑brush occlusion for realistic skyline integration. Now includes manual control of the launch base height, enabling ultra‑low detonations or majestic high‑rise launches. ● Media Output Capture HD snapshots or record 30‑second MP4 videos with spatial audio. ● Cultural Guide A bilingual booklet introduces Japanese concepts like Ma (the silent pause) and Yoin (the lingering glow). ● Tap‑to‑Launch Mode Tap anywhere on the screen to fire shells precisely at that point. ● Color Themes 12 refined presets with fine‑tunable grading for seamless blending with your scenery.

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.
