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

Knee Biomechanics with Dr. Bertram Zarins is an exceptional resource for exploring the anatomy and biomechanics of the human knee. Developed in collaboration with Dr. Bertram Zarins, whose expertise ensures the highest level of anatomical accuracy, this app offers a comprehensive and interactive learning experience. Key features include: • High-quality 3D model of the bones, ligaments, muscles and tendons of the knee, allowing detailed examination from every angle. • Interactive motion simulation that demonstrate knee biomechanics, including the screw-home mechanism, during flexion and extension—helping you better understand functional motion patterns. • Layer-by-layer exploration of anatomical structures for an in-depth study of the knee joint. • Realistic visualization of ligament tension and joint kinematics, which can be difficult to observe using traditional resources. • Access to informative articles and resources from anatomystandard.com, curated to enhance your understanding of knee anatomy and biomechanics. • Detailed examination of cartilage surfaces and menisci, providing insight into joint health, load distribution, and clinical relevance. • Adjustable lighting and visualization settings to optimize your study of intricate anatomical details. Whether you are a student, healthcare professional, or simply interested in understanding the mechanics of the knee, Knee Biomechanics with Dr. Bertram Zarins is an invaluable tool. With its detailed 3D models, accurate simulations, and expert guidance, it is an essential resource for anyone looking to deepen their knowledge of knee anatomy and function.

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.
