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.

What do you get if you cross a Stylophone with the famous Roland SH-101? Well We have circuit-bent a virtual Stylophone and added Roland SH-101 modifications. You can create wacky and eerie sounds to meaty bass lines. As well as the Stylophone sound, you now have an extra oscillator driving a sawtooth wave with filter and resonance from the SH-101. You can adjust the mixer for each oscillator and the LFO can control oscillators and amp. We have increased the LFO speed and depth of the pitch modulation. We have also added an SH-101 style sequencer for creating bass lines or arpeggios. It is still monophonic but the notes will continue to decay if you release your finger before playing another key. You can also play over the top of the sequence while its playing.

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.
