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.

'DayColor' manages 'Journal, Countdown, to-do' at once. Easily and conveniently record what you see, enjoy, and feel in your daily life. ◆ Main features ◆ # Record memorable moments with your own color. I think color can be interpreted in various ways depending on each person's experience. Imagine and express your own color. We prepared various colors, fonts, and stickers. Designing your day in your own way makes an ordinary day special. # Record your day with photos and colors. If you have photos and texts that you want to cherish, use the 'Photo Journal', and if you want to express your feelings and design them lightly, try using the 'Color Journal'. # Smart self-management app In addition to the diary, there are Countdown and To-Do functions together. This is an opportunity to easily manage self-management that was once difficult. Organize your cluttered mind in a simple way, and plan ahead for the upcoming important day. It will surely become a happy memory. # Simply recall your memories. You can see important memories and emotions of this month at a glance through the calendar view and timeline view. And, since you can link journals to events, it is convenient to recall memories for each event. ◆ Other ◆ • Provide timestamp and weather information input. • Various countdown types are provided.

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.
