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

Is that blob on the beach dangerous? What’s the best treatment? The Jellyfish App is a one-stop-shop for safety and identification of jellyfish of the world. This feature-rich app puts expert knowledge at your fingertips so you can make informed decisions that will help you have a good, fun, safe time at the beach. The Jellyfish App offers the following features: • CURRENT ALERTS: With one tap from the Home Screen, instantly see which species and localities have current alerts. • JELLYFISH NEAR ME: Instantly check what species are found near you, while an interactive map allows you to tap or type a locality to see what jellyfish occur anywhere in the world. • ASK DR LISA: Upload photos or questions for direct access to Dr Lisa-ann Gershwin, an international jellyfish expert with 25 years’ experience. You’ll not only get personalized answers back, but as well, your photos and observations will assist in tracking these fascinating creatures. You’ll be acting as a “para-scientist”, and helping science! • SPECIES INFO: Each entry contains common and scientific names, a photo, description, seasonality, locality, toxicity, sting treatment, and other interesting information. • ENCYCLOPEDIA: Instant access to a wealth of useful information about jellyfish around the world. Hundreds of species are already included, from pretty ones to dangerous ones, and more are being added regularly. • SEARCH: Find species by common name, scientific name, or image. A text search function helps even if you only know part of a name. Preloaded search options for color, size, and shape enable you to find species by feature (for example, all coin-sized species, or all purple species). • FAQ: Should you pee on a sting or does vinegar really work? Wondering when is the best time to swim, or what sort of protective clothing to use? Check out the Frequently Asked Questions for the answer to these and other queries. • MULTIPLE LANGUAGES: The Jellyfish App is now available in English, Chinese, French, and Spanish.

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.
