Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
PagePulse shows you the emotional landscape of any book before you start reading. Every book gets an Emotional Fingerprint — a visual map of fear, joy, sadness, anger, and hope across its chapters. See the emotional arc at a glance: where the gut punches land, where hope returns, and how dark it gets. WHAT YOU GET — Emotional Fingerprint: A colour-coded chapter-by-chapter breakdown of a book's emotional DNA. Five emotions tracked across every chapter. — Verdict Card: Pulse, darkness index, complexity, hope arc, and content warnings — the essential read on any title, delivered before page one. — Shelf Scan: Point your camera at a bookshelf. PagePulse reads the spines, identifies the books, pulls in covers and metadata, and queues analysis — in one shot. — Reading Patterns: See your library's emotional profile. Which emotions dominate your shelf? How dark do you read? What's your complexity sweet spot? — Weekly Recommendations: Curated picks based on your reading patterns, emotional preferences, and library gaps. Not bestseller lists — books that fit you. — Goodreads & StoryGraph Import: Bring your existing library. Drop a CSV export and PagePulse analyses every title. HOW IT WORKS For public-domain books, PagePulse reads the actual text. For in-print titles, it works from careful inference — themes, reviews, the author's wider body of work — to produce the same emotional fingerprint. Either way, you get the full picture before chapter one. Your data stays private. No ads, no tracking, no subscriptions. One purchase, everything included. Built by Affordance Design Studio.

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.
