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 world's first artist-driven white noise app, feature six exclusive soundscapes from a formidable lineup of independent music visionaries. More than two hours of exclusive white noise from: • Academy Award-nominated composer OWEN PALLETT • Ambient music icon ELUVIUM • Hugo-award-nominated industrial hip-hop theorists CLIPPING. • Genre-hopping harp journeywoman MARY LATTIMORE • Mind-bending experimental pianist KELLY MORAN • Legendary wildlife recordist CHRIS WATSON. These longform explorations of static, drones, fuzz, wind and spectrum-filling oblivion make Fuzzzel not only a utilitarian sound-making device but a one-of-a-kind creative platform. Fuzzzel reroutes the demand for white noise into the hands of professionals, sound artists and creatives. Every piece on Fuzzzel is a lengthy, exclusive ambient journey created with the pulse of a human being and the ear of a gifted musician. Each piece — together totaling more than two hours of new music — loops indefinitely alongside a unique video provided by each artist. Fuzzzel offers no preference or aesthetic suggestions on how you appreciate these works. All of them are equally appropriate for • background noise • sleep aid • meditation • concentration • work • home atmosphere • relaxing • airplanes • deep listening • yoga • party accompaniment • daydreaming • focus • thinking • exercise • part of your everyday music rotation The musicians on Fuzzzel comprise some of today's most forward-thinking and acclaimed artists, all blurring lines between independent rock, modern classical composition and avant-garde sound art. Over the course of more than two hours of original sound, their drones run the gamut from the delicate to the thunderous. Mary Lattimore creates a fragile soundworld from harp, Moog and copper handbells, while Eluvium summons wave upon wave of churning analog seastorms. Owen Pallett's piece recalls the wind-battered plains of a Cormac McCarthy novel, while Kelly Moran's Prophet synthesizer culls the cosmic woosh of classic kosmische. Clipping.'s piece is constructed of the "outer space" backgrounds of their Hugo-award-nominated 2016 sci-fi concept album 'Splendor & Misery' — each ambience represents a different room inside the interstellar vessel where the album’s story takes place. Chris Watson, whose field recordings can be heard on David Attenborough's beloved 'Life' series of BBC documentaries, provides a blustery audio snapshot of the Spanish peninsula of Cap de Creus, where you can surround yourself in wind gales and birdsong.

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.
