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
What people are saying: "StashBot is that perfect combination of grace, functionality, and ease-of-use. Behind the pretty face, though, an intelligent engine delivers numbers you can trust. Unless you're a math genius with all the charts in your mind, this is the best $5 you'll ever spend on a knitting app." - Clara Parkes, Knitter's Review "StashBot is as pretty as it is clever." - Meghan Fernandes, Pom Pom Quarterly "Yardage requirements never looked so good." - Amy Herzog, CustomFit Buy yarn....smarter. StashBot is your yarn shopping companion! When you find a yarn you can't live without, use StashBot to figure out how much to buy. StashBot will pay for itself again and again as it saves you from buying more yarn than you need you need. At the same time, it ensures you will purchase enough yarn to knit the sort of projects you like. StashBot includes yarn requirements averages for gauges 3 - 8 sts per inch / 2.5 cm. Categories include: - Vests, shrugs and sweaters (cropped, average and tunic length) in size 3 months - 62" / 157cm bust circumference. - Hats, socks, and mittens in sizes Baby, Toddler, Child, Adult & XL Adult. - Scarves, shawls, and infinity cowls in 3 typical dimensions. All yarn requirements are presented in both YARDS and METERS, and you can easily switch back and forth between imperial and metric measurements. YARN SHOPS: This is a great tool for you shop as it encourages knitters to purchase sweater quantities of yarn!

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.
