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
CortexID is an age verification application developed by Code Corporation, using the powerful CortexDecoder to quickly read barcodes from United States government issued identification and determine patron age for purchase of age restricted products or entry into age restricted establishments. The application complies with the state requirements of Utah for storage of data for audit purposes. Other states will be added in future releases. Please view our privacy policy for more information. CortexID provides 50 free trial scans to try out the barcode scanning capabilities. If you like the product, you can purchase a Standard auto-renewing subscription that provides unlimited barcode scanning for the price of $9.99/month. Your subscription will automatically renew each month and be charged to your iTunes account within 24 hours of the end of the current period, unless auto-renew is turned off at least 24 hours before the end of the current period. You can turn off auto-renew at any time from your iTunes account settings. Refunds will not be provided for any unused portion of the current term.

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.
