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
The app helps you to align your satellite antenna. Based on your location and the selected satellite the app shows you in which horizontal and vertical direction you have to align your antenna. As an additional function you can check with the app if obstacles are interfering with the reception. In the current version you can choose from more than 400 satellites. Depending on your location the following satellites are available: ABS 75° E ABS-2 ABS-2A ABS-3A ABS-4 ABS-6 ABS-7 AMC 11 AMC 15 AMC 16 AMC 2 AMC 21 AMC 3 AMC 4 APSTAR 6C APSTAR 7 APSTAR 9 ARSAT 1 ARSAT 2 Al Yah 1 AlComSat 1 Amazonas 2 Amazonas 3 Amos 17 Amos 3 Amos 4 Amos 4° W Amos 7 Anik 107.3° W Anik F1 Anik F1R Anik F2 Anik F3 Arabsat 30.5° E Arabsat 5A Arabsat 5C Arabsat 6A AsiaSat 5 Asiasat 6 Asiasat 7 Asiasat 9 Asiastar 1 Astra 19.2° E Astra 1KR Astra 1L Astra 1M Astra 1N Astra 28.2° E Astra 2E Astra 2F Astra 2G Astra 3B Astra 4A Astra 5B Azerspace Azerspace 2 BELINTERSAT-1 Badr 26° E Badr 4 Badr 5 Badr 6 Badr 7 Bangabandhu-1 Brasilsat B4 BulgariaSat-1 ChinaSat 10 ChinaSat 6A ChinaSat 6B ChinaSat 9 Chinasat 11 Chinasat 12 Chinasat 16 Ciel 2 Directv 10 Directv 102.8° W Directv 11 Directv 12 Directv 14 Directv 99° W Echostar 10 Echostar 11 Echostar 110° W Echostar 12 Echostar 14 Echostar 15 Echostar 16 Es'hail 1 Es'hail 2 Es'hail 25.5° E Eutelsat 10A Eutelsat 113 West A Eutelsat 117 West A Eutelsat 12 West B Eutelsat 133 West A Eutelsat 13° E Eutelsat 16A Eutelsat 172B Eutelsat 21B Eutelsat 33E Eutelsat 36B Eutelsat 3B Eutelsat 48D Eutelsat 5 West A Eutelsat 7 West A Eutelsat 70B Eutelsat 7B Eutelsat 7C Eutelsat 7° E Eutelsat 8 West B Eutelsat 9B Eutelsat Hot Bird 13B Eutelsat Hot Bird 13C Eutelsat Hot Bird 13E Express 140° E Express AM3 Express AM33 Express AM44 Express AM5 Express AM6 Express AM7 Express AM8 Express AMU1 Express AT1 Express AT2 GSAT 10 GSAT 15 GSAT 17 GSAT 18 GSAT 93.5° E Galaxy 14 Galaxy 15 Galaxy 16 Galaxy 17 Galaxy 18 Galaxy 19 Galaxy 23 Galaxy 25 Galaxy 28 Galaxy 3C HellasSat 2 HellasSat 3 HellasSat 39° E HellasSat 4 Hispasat 30W-5 Hispasat 30W-6 Hispasat 30° W Hispasat 74W-1 Horizons 1 Horizons 2 Hylas 1 Insat 4B Insat 4CR Intelsat 10-02 Intelsat 11 Intelsat 14 Intelsat 15 Intelsat 17 Intelsat 19 Intelsat 1R Intelsat 20 Intelsat 21 Intelsat 22 Intelsat 25 Intelsat 28 Intelsat 31.5° W Intelsat 33e Intelsat 34 Intelsat 35e Intelsat 36 Intelsat 37e Intelsat 39 Intelsat 68.5° E Intelsat 903 Intelsat 905 Intelsat 906 Intelsat 907 JCSat 3A JCSat 4B JCSat 5A JCSat 6 Kazsat 2 Kazsat 3 Koreasat 5 Koreasat 6 LAOSat 1 Measat 3 Measat 3A Measat 91.5° E N-SAT-110 NSS 10 NSS 12 NSS 7 NSS 9 Nigcomsat 1R Nilesat 201 Nimiq 1 Nimiq 4 Nimiq 5 Nimiq 6 Optus 10 Optus 156° E Optus C1 Optus D1 Optus D2 Optus D3 Paksat-1R Paksat-MM 1 Palapa D QuetzSat 1 Rascom 1R SES 1 SES 11 SES 12 SES 14 SES 2 SES 3 SES 4 SES 5 SES 6 SES 7 SES 8 SES 9 SES 95° E ST 2 Sky-Mexico 1 Star One C1 Star One C2 Star One C3 Telkom 2 Telkom 3S Telstar 11N Telstar 12V Telstar 14R Telstar 18 Thaicom 5 Thaicom 6 Thaicom 78.5° E Thaicom 8 Thor 0.8° W Thor 3 Thor 5 Thor 6 Thor 7 Thuraya 2 TurkmenAlem Turksat 3A Turksat 42° E Turksat 4A Turksat 4B Vinasat 1 XTAR-LANT Yamal 401 Yamal 402 Yamal 601

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.
