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

In contrast to most other modeling tools, Plastic does not use polygons to define the shape of an object. Instead, you build up a volumetric representation by simply combining primitives with add and subtract operations. The same tools used for modeling can also be used to apply color to the model in one continuous workflow. And, since all of these actions in Plastic are non-destructive, you can easily change aspects of your scene at any point without affecting unrelated work. When you are done, objects can be exported as PLY files to be animated, rendered, or 3D printed with the help of other tools. To get started, create a new project by tapping the “+”-symbol in the project gallery. To edit an object in the scene, you can either tap it twice in the outline or tap the “Edit” button after selecting it and switching to the attributes panel. By tapping the plus button in the outline panel, you can now add strokes to your object and build up its shape. Although I am trying my best to provide a polished experience, Plastic is still in an early stage in its development and occasional bugs, missing features, and frequent design changes cannot be completely avoided. If you are interested in updates on the development progress, feel free to follow me on Twitter @raffael_kaehn. For feedback, please send me a direct message or an email to [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.
