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.

Boat School is an iOS App made for anyone finding themselves preparing for a U.S. Coast Guard License Exam. Split into general sections, such as Refrigeration, Safety, and Electricity, users can select any section to study from. Once a section is selected, the app allows users to select from subsections within a given section. Once selected, questions from that subsection will appear in a scroll content view with two main modes: Study Mode - for those looking to just let telepathic osmosis take over 5 mins before the exam, answers are revealed to questions. Quiz Mode - an interactive mode where users get to guess the correct answer to each question, allowing as many guesses as it takes to get the right answer. Once every question in a section is answered, the quiz results will appear on the user’s initial guess to each question. Beyond these two general modes, there is also a controllable tab on the main section view allowing user’s to filter questions to just exclusively 3 A/E questions, or keep it unfilitered to the full 14k question bank. As a final feature to ease the study grind, a search feature has been implemented based off of key words. Questions and answers containing each of the words in the search bar will appear in ‘Study Mode’ as a search result. Enjoy!

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.
