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.

Experience more than 250 years of history with the official Freedom Trail® app! Boston’s revolutionary past comes to life with this innovative app, including a self-guided audio tour, interactive map, pictures, and more. The iconic 2.5-mile Freedom Trail connects 16 of America’s most significant historical landmarks, including museums, churches, meeting houses, burying grounds, parks, a ship, and historic markers that tell the story of the American Revolution and beyond. Special Features of this App: - Over 1.5 hours of audio content tells the stories of the Freedom Trail, including music and guest interviews with historians, academics, authors, and others. - The audio for each stop plays automatically thanks to GPS mapping. - An interactive map helps you find your next stop on the Freedom Trail with ease. - Photos and illustrations help direct your eyes and place you within the stories covered. This app is an official product of The Freedom Trail® Foundation. Established in 1964, the Freedom Trail Foundation is a 501(c)3 nonprofit organization that markets, promotes, and helps to preserve the Freedom Trail through visitor services and programs, educational programs, and marketing and public relations efforts. The Foundation’s Preservation Fund helps support preservation, rehabilitation, and capital projects for official Freedom Trail historic sites; these projects help avoid, minimize, or mitigate adverse effects of the elements and manmade wear and tear of Boston’s precious 17th-, 18th-, and 19th-century sites.

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.
