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

CT Pass Quiz is an anatomy learning app made for everyone who wants to learn human anatomy. Nowadays, we see 3D images on a daily basis, but in order to really understand them in 3D, we need to analyze the flat image and reconstruct it in our head. This app asks the anatomy name displayed on the CT image in a quiz format, and you can learn image anatomy efficiently by switching the axial section, coronal section, and sagittal section and selecting the answer from the 4-choice question. I will. [Recorded image] Chest CT image Axial cross section Number of slices: 39 Coronal section Number of slices: 25 Sagittal section Number of slices: 37 Number of dissection names: 62 items 【function】 ■ Cross-section switching display By selecting the sub screen, it is possible to switch between the axial section, coronal section, and sagittal section to check various cross sections. ■ Display of anatomical range By displaying the anatomical range on the image, you can answer while checking the anatomical names around you. ■ Lung field / mediastinum display You can switch between lung field and mediastinum. ■ Enlarged display You can change the size of the image by pinching in and out of the screen. ■ Multilingual support (English, German, Japanese, Chinese, Italian, French, Spanish, Korean, Arabic, Portuguese, Russian, Hindi, Vietnamese)

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.
