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

The "color wheel", also known as "color circle", is a useful color tool. It reflects the hue, saturation and brightness of the color. Through it, you can easily choose the color combination you like. At the same time, you can clearly see the relationship between colors, such as warm colors, cool colors, contrast colors, similar colors, and so on. In this application, you pick colors on the color wheel. In particular, you are free to adjust the color wheel, for example to change its color range or structure. You can even define a color wheel with a maximum of 48 segments, 12 levels, and a total of 576 colors. Saving colors is another major feature of this app. Once you have chosen the color combination you like, you can save it. You collect various colors and build your own color library. ~~~~~~~~~~~~~ 【Features】 ∙ Multi-color combination: up to six colors can be combined ∙ Color collection management: multi-color and solo-color independent collection, support for naming, sorting and copying ∙ Custom color wheel: define the number of levels, set the range of purity and brightness, etc. ∙ Sliding color selection: slide directly on the color wheel to select the color ∙ Color ruler: indicates the color wheel, similar color, contrast color range in which the color is located ∙ Multiple numerical modes: support HSB, RGB numerical representation, support for integer, decimal representation ∙ Color card: show the color scheme as a card ∙ Color data text export: copy to system paste board ∙ Color card image export: export to album or share to other apps ~~~~~~~~~~~~~ 【Contact】 If you have any questions, suggestions or comments, please contact us at [email protected].

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.
