A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Lola is adorable! Her smart and beautiful story app is as fun as a video game and as educational as a book. Its graphics have been optimised to make it easier for children to read. With just a simple touch, you can choose between uppercase and lowercase text, and listen to the story, or just read it alone with the aid of special rulers. It is safe, 100% publicity free, perfect for any child, and dyslexic friendly. Every page is fully animated and interactive… Even the chandelier moves! Download Lola Slug at the Exhibition now, kids will love it! WHY WILL YOU LIKE LOLA SLUG? + Cute characters living everyday life, 19 fun scenes to return again and again, your kid will smile from the first page! + Either all-in-uppercase text and in the normal case with “big” and “small” letters + Two variant of lowercase “a” so that you can choose your favourite “a” to be either cursive or standard. + High-readability font expressly designed for beginning readers with or without dyslexia. + Reading rulers to help focus and track on one line at a time. + Professional narration: listen and spot words get highlighted one by one. We have selected young actors with natural, never annoying kids' voices so that Lola Slug's narration is pleasant even after 1000+ readings! WHAT IS A “READING RULER”? It is a transparent coloured ruler and depending on the child, it can improve reading ability considerably, because it helps focus and track on one line at a time, and reduces the glare on the page by providing the correct colour contrast between letters and background. You can find it on the left hand of every page on the “Read Myself” mode and drag it on the text up and down. You can also change its background colour by swiping it right, or decide to leave it in a corner when you do not need it. WHAT DO YOU MEAN BY “HIGH READABILITY”? We noticed that most children's books and apps use fonts not suitable for beginning readers. For that reason we developed a new font for primary school children, designed in line with how kids are taught to write: You can choose your favorite lowercase “a” to be either cursive -the most taught at school around the world- or standard. Every letter has its own different shape so that you can well distinguish p, b, q, d, n, u, I (el), I (uppercase i), and 1 (one) even if you are seeing them mirrored or rotated like many beginning readers do, not just the dyslexic ones. Backgrounds are light gray or coloured in order to prevent flashing effects on brilliant screens. Though you may not even notice it, the letter spacing is almost double than usual. In fact recent studies seem to indicate that an increased letter spacing significantly improves dyslexic children's speed and accuracy in reading, and it absolutely does not disturb kids who read normally. Could an almost unnoticeable graphic solution be so helpful? We have immediately put it into practice! Don’t wait any longer and read Lola Slug at the Exhibition now!

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
