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.

UfYH: Terrifying motivation for lazy people with messy homes. Please be advised that this app contains profanity. The word "filth," in-app, is replaced by the other f-word. There is a lot of swearing. Really so very much swearing. Please do not buy this app and then be shocked by the swearing, because there is a lot of it, and here we are, telling you about it right up front. If traditional housekeeping isn’t really your style, but your living space needs a little attention, UfYH’s challenges and customizable features will help you get your place back in shape, a few minutes at a time. Rather than encourage marathon cleaning sessions, UfYH gives you the tools to clean up, a little at a time. Unf&%*ing your habitat turns dreaded chores into easy-to-complete tasks, with a hefty dose of “filthy” language to motivate you to clean up. -Clean and simple easy-to-use interface. -Select timed challenges in 5, 10, or 20 minute intervals and try to beat the clock to finish the challenge. -Select challenges by room. -Create a customized to-do list and reminders to keep you on schedule. -Earn achievements for completing challenges or finishing your to-do list. -Use the 20/10 timer to reward yourself with a 10-minute break for every 20 minutes of work. Shorter challenges count cumulatively toward your total time. -Random motivators remind you that excuses are boring and use a combination of a little guilt, a little shame, and a little swearing to get you moving. UfYH is especially useful for those who don’t have a lot of spare time to devote to cleaning: students, people with full-time jobs, people with roommates, anyone who can’t find the motivation to get up and just do something. Even if it’s just a little something! Our lives are complicated and messy, and we’re often overwhelmed and distracted, and sometimes a little lazy. Unf&%* things and see a remarkable difference in how you tackle cleaning. UfYH uses frequent profanity and is for mature audiences. In-app, the word "filth" is replaced by its older, more foul-mouthed cousin. This app uses the "f-word." A lot. Please be aware of this before purchasing.

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.
