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

This is an animated storybook app, which will humorously help teach your child early reading and logic skills. Interactive storytelling gets kids excited to read along! ** Parents' Choice Gold Award! ** ** Winner of Appy Award: Best Book App! ** ** Reached #1 in Books! on App Store** ** Common Sense Media 5-Star Quality Rating ** There’s something waiting at the end of this book. Could it be…a monster?!? Loveable, furry old Grover is about to find out—and he’s bringing his equally loveable and furry friend Elmo with him! In this sequel to the best-selling, chart-topping Monster at the End of This Book app, Grover invents silly, giggle-worthy ways to prevent young readers from getting closer to another monster hiding at the end of this story. But an ever-curious Elmo asks for your help to slip past Grover every time. FEATURES • Bursting with innovative activities woven right into the story. • Funny animation featuring the voices of Grover AND Elmo • Engaging activities that build vocabulary and spatial-relations skills • Word highlighting for beginning readers • Intuitive finger-tapping, so little ones can play independently • Bookplate personalization to add your child’s name • Parents’ tab to help you and your child get even more from the app experience • Protective "baby-gates" to ensure a child-safe and child-friendly experience TIPS Remember, you can always turn down the volume so that you can bring your own voice to the story for your kids. Young readers will delight in the very funny story, and parents will know that their little monsters are reading, laughing, and learning with trusted, beloved Sesame Street characters.

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.
