Generating… usually about a minute.
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.

Catador replicates the industry standard SCAA coffee cupping scoresheet with an easy-to-use system of sliders to rate sensory criteria and tick boxes to mark off-cups in the categories of Uniformity, Clean Cup and Sweetness. Touching the Notes line launches a virtual keyboard so that you can record your comments and total scores are tallied immediately and accurately on the right hand side in the Total Score box. So simple, and yet it works perfectly. Catador goes further to include administrative features that make it even more useful in the field. From the Home screen, you can add and delete cupping flights, identifying the number of samples in each group, which are given generic alphabetic labels or numbers that can be given unique names. (Both Arabica and Robusta are available) After the day’s cupping is done (or when asked to turn in your Q Grader cupping evaluation), users can also permanently lock each flight so that it cannot be changed later. The system gives you a popup warning that the operation cannot be undone. No cupping scoresheet application can be fully functional in the real world unless you have some way to export the data. Catador presently includes an email function that sends scores as a text document to any email address, as well as a .CSV file which may be imported into other applications or a worksheet. There is also an Airprint option, where you may print the output to any Airprint enabled printer wirelessly. On the latest version, you may also share your sessions using the Airdrop feature on all supported iOS devices.

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.
