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
Use an iOS device as a signature capture pad for your nearby computer. Autograph works great for a variety of professional office needs such as medical or real estate. Simply hand the device to your client or patient, and their signature will appear on your nearby Mac or PC. A note about pricing: This app is designed for office use and priced slightly higher to discourage casual use, with our sincere apologies to any potential casual users. More information: Finally, Go Paperless! To use autograph, just sign your name and hit send. It will appear on the screen of a nearby computer. Wifi network is required! Drop your signature into Word, Excel, Pages, iChat, Numbers, Stickies, PDFPen, Preview, and many other applications on your Mac or PC! A small, free program named Autograph Helper must be installed on your computer to receive the signature. For OS X: https://tenonedesign.com/apps/autographhelper/autographhelper.php For Windows: https://tenonedesign.com/apps/autographhelperwin/autographhelperwin.php For the best results, we recommend using a Pogo-branded capacitive stylus. https://tenonedesign.com/pogo

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.
