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.

Dub Siren DX brings reggae sound system culture to your iPhone and iPad. Originally released in 2008, it continues to evolve, with active users including Carl Craig and Mark of Iration Steppas. Create your own dub sessions with vintage-style sirens, artist samples, delay, filter and reverb effects, or play along live with curated reggae, dub, jungle, drum & bass and dubstep radio stations. NEW IN THIS VERSION: THE SIREN SHOP Seven new synth sirens, all generated live in the app, with no samples or downloads. Try any of them free for 20 seconds on the siren key, then unlock the ones you love, or get ALL SIRENS in one purchase. • DIGI HORN: the classic DJ air horn. BLAST, CLASH and FAT. Pull PITCH down for a deep ship horn. • SYNARE: the legendary late-70s drum siren. Hit it, dive it, zap it! • RAID: wind up the classic air-raid siren and let it wail. • DIGI 1: zap it, bleep it, bomb it. Pure 80s digital FX. • DIGI 2: bubble it, wail it, level it up. • DIGI 3: coin it, rewind it, ring it. • BASS DROP: sub drops, wobble bass and booms. Protect your speakers! Also new: the CRT screen reacts to the bass, and the radio is more stable. FEATURES • Vintage analog-style siren oscillator, plus the NJD and LICKSHOT sirens • NJD: a live model of a classic 555 circuit-bent analog siren, with deep dives, a power-up snap and a sagging tail when you let go • LICKSHOT: the sound system laser gun, from non-stop zaps to a machine gun • SIREN SHOP: seven optional synth sirens, each playable as a 20-second preview • Factory sound packs and optional artist packs • Delay, Bass Cut and High Cut effects • MUSIC VERB plate reverb with TAP TEMPO sync (iPad) • Curated internet radio with automatic station-list updates • ONLINE station filter and station playback history • Music library playback • Real-time audio spectrum analyzer and CRT screen artwork • Interfaces for iPhone and iPad SOUND PACKS Classic Sound, Weapon, U-Roy, Yellowman, Sci-Fi, Pro DJ, Selecta Tools and Cultural Warriors. Optional artist packs include Lee “Scratch” Perry, Mad Professor, Scientist, Ranking Joe, Joe Lickshot, VP Records, Jahtari, Ninja, Big Youth, Zion Train, DJ Vadim and Max Romeo. Some sound packs and the Siren Shop sirens require an additional in-app purchase. Radio stations in the app have authorized playback of their live streams. Radio availability and song information depend on the broadcaster. Artist visuals are available for selected packs. All sound packs are copyright protected. Copying samples to other media or equipment for commercial use requires prior permission.

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.
