Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
NAM brings the power of Neural Amp Modeling to iOS. Load real amplifier captures (.nam files) and impulse responses (.wav) to create your perfect guitar tone — all running as a low-latency AUv3 effect. Features: • Load any NAM profile (.nam) for authentic amp and pedal sounds • Load custom cabinet IRs (.wav) for speaker/mic simulation • 3-band tone stack (Bass, Mid, Treble) matching the official NAM plugin • Noise gate with adjustable threshold • Input gain and output level controls • Normalized, raw, and calibrated output modes • Works in GarageBand, Logic Pro, AUM, and any AUv3-compatible host Whether you are practicing at home, recording in the studio, or performing live, NAM delivers the sound of real amplifiers right on your iOS device. Where to get models: thousands of free amp captures and cabinet IRs are shared by the community on sites like TONE3000 and ToneHunt. Download any .nam or .wav IR file, open it in NAM, and play. Works great in GarageBand, Logic Pro, AUM, Koala, Cubasis, Loopy Pro, and any AUv3 host. NAM is a player-only implementation — it loads and plays existing model captures but does not perform training or model creation. Neural Amp Modeler (NAM) was created by Steven Atkinson. This app is an independent iOS port of the NAM player and is not affiliated with the official NAM project. The official NAM desktop plugin and source code are available at https://neuralampmodeler.com. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
