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.

Follow the path of ancient civilizations, frontier explorers, and Civil War generals along one of America's most storied corridors. The Natchez Trace Parkway stretches 444 miles from Natchez, Mississippi to Nashville, Tennessee — and this guide brings every mile of its history to life. Natchez Trace: An Ancient Road, features 60 carefully researched historic sites, each with rich narrative histories, AI-generated photography, and GPS-powered navigation to get you there. Whether you're a first-time visitor or a seasoned road tripper, this is the companion guide the Trace deserves. WHAT'S INSIDE • 60 historic sites from Mississippi through Alabama to Tennessee • Deep-dive histories and cultural significance for every stop • One-tap GPS navigation to each site • Favorites system to save and revisit your must-see stops • Stunning AI imagery at every location • Audio narration — hear the stories as you drive or when you arrive • Works offline — no signal needed on the Parkway THE STORY OF THE TRACE Long before European contact, Native American nations — Natchez, Chickasaw, Choctaw — traveled this path through the wilderness. Flatboatmen returning from New Orleans walked it home. Meriwether Lewis died mysteriously along it. Andrew Jackson marched troops across it. The Civil War left its mark on nearly every county it passes through. This app tells all of it. PDR HERITAGE ROADS Natchez Trace: An Ancient Road is part of the PDR Heritage Roads family of premium travel history apps, alongside the Route 66 Centennial Guide and the PCH Complete Historical Guide. Each app is built for travelers who want more than a map — they want the story. One-time purchase. No subscriptions. No ads. Lifetime updates.

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.
