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.

Set Up Your Child for Reading Success, for Less! GraphoGame Helps Kindergarten and Elementary School Kids Learn to Read and Spell Letters, Syllables and Words with American English Phonics.

Never Pay More for New Content or Features! GraphoGame was created by pedagogical experts, linguists and neuroscientists from Yale and Cambridge Universities to achieve basic literacy in children - from kindergarten onwards. Research trials show that by playing just 15 minutes, 3 times per week, kids can improve their letter knowledge, phonics awareness, reading speed and overall confidence in literacy. Literacy outcomes are equivalent with 1-to-1 teacher support as shown by a randomized controlled trial conducted by the Centre for Neuroscience in Education, University of Cambridge. Witness kids learning their first letters, syllables and words at home or in school with GraphoGame! Kids learn to read with American English phonics and a variety of engaging 3D levels – all with their own unique avatar. Players gradually move from graphemes and phonemes, through vowels, consonants, syllables and rhymes, to eventually learn how to blend what they have mastered into complete words. Play at home or in school! This version of GraphoGame is the result of work done by Haskins Laboratories, an independent, not-for-profit research institute founded in 1935, investigating the biological basis of speech, language and reading, and their related disabilities. GraphoGame is based on decades of research in dyslexia, autism, neurolinguistics and phonics by the University of Jyväskylä in Finland and was adapted to English by the University of Cambridge Centre for Neuroscience in Education and Yale’s Haskins Laboratories. Kindergarten to grade 3 students - including those with dyslexia - have shown the most literacy improvement playing GraphoGame American English. Visit www.graphogame.com to learn more.

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.
