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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Tired of repeatedly purchasing items that you already have at home? Always forgetting when the food in the fridge is about to expire? YSITV-MyStock offers you a one-stop solution for managing your household inventory, making your life organized and eliminating waste. 【Core Function】 - Ultra-fast barcode scanning for inventory entry: Equipped with a high-performance barcode scanner, items can be entered instantly. It supports custom classification and storage locations (such as "Kitchen", "Basement"), making it easy to find items. - Intelligent expiration warning: An intuitive dashboard displays "To-do items for today" and "Items about to expire" in real time. This effectively prevents food spoilage, saving money and being environmentally friendly. - Shopping list linkage: When an item falls below the "safe stock level", it is automatically marked. With one click, low-stock items can be added to the shopping list, achieving a seamless loop from "detecting out-of-stock" to "completing replenishment". - Professional inventory checking mode: The unique inventory verification function allows for entering the actual quantity and automatically calculates the variance (Variance) to ensure consistency between accounts and reality. - Privacy first, offline usable: We understand the sensitivity of family data. This application does not require registration or login, and does not need an internet connection. All data is fully stored locally on your device. Supports CSV/PDF data export for backup.

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.

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.
