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.

another app in our north american wildlife app series... fishes are cold-blooded vertebrates that live in water and breathe dissolved oxygen through organs called gills. they are generally characterized by their size, shape, feeding habits, and water temperature preference (their habitat). the freshwater fishes of california app shows 111 species that are found (native or introduced) in the freshwaters of california. please note that some species, such as salmon or steelhead trout, may no longer be present upstream of dams that lack fish passage. the freshwater fishes of california present the identification criteria of each species and – if species within the same family have distinguishing features – these features are listed for easier identification. apart from these identification descriptions of each species, the distribution of the species is given, as well as any other names and high-resolution photos. a glossary of over 400 special terms related to fishes is included, as well as high-quality illustrations explaining the internal and external anatomy of fishes. comfortable search functions are also part of the stylish and intuitive user interface and allow you to search for fish names and also do fulltext search in the descriptive text.

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.
