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.

You can select your favorite fishes to display. The clock inside the background offer 24/12-hour mode, you can also choose to hide the clock. * Fish Tank iOS Widgets: EasyFish offers three different sizes of widgets to let you have a mini fish tank on the device’s home screen. The small and medium-sized widget has clock and fish animation. The large-size widget can display built-in funny dialogues or note that you input from the widget configuration. * Easy Dialogues: Funny dialogues will show up randomly. When it shows up, it will replace the clock and last for 30 seconds.

Turn it on and let it calm your nerves and keep your focus at work. * Fishes Interaction: Try clicking the fish and see fishes rush after being shocked.

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.
