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.

impcat (short for Interactive Miniature Painting Catalogue) is a simulator for photorealistic painting results on gaming and tabletop miniatures. This tool gives you a variety of miniature images with individually customizable body sections, that you can paint with colours you own or perhaps wish to purchase. It works with predefined colour palettes, using names and values as promoted by their manufacturers. To achieve a high quality result the system simulates a four step painting process: Base colouring, layering, shading and highlighting. Features: - A set of 6 built-in miniatures, by Artel "W", with up to nearly 30 individually paintable sections - A set of built-in colour palettes, as well as additional palettes from our DLC server (around 1000 paints to choose from, and growing) - A file handling system for importing custom image and paint templates (visit impcat.de/faq for instructions) - Access to a growing online library of free DLCs (visit impcat.de/about for full list of contents) - An automated complement recommendation mode that lets you select a base colour and then automatically applies harmonizing layer, shade and highlight paints, which you can then customize at will. - A photorealistic simulation of the applied paints. - A shopping list generator that collects the data of all applied colours and gives you the links to the corresponding shop pages - Saving and loading options for your colour configurations - A colour creating tool, for creating opaque and metallic paints of any colour you like - A colour mixing tool, for testing mix results of your paints - A randomizer, for getting colour scheme inspiration by letting impcat ramdomly distribute a set of colours across the model

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.
