A product spec, screen plans, and build steps for your coding agent.

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.

This is the most advanced carburetion simulation application on the market for Dellorto VHSB34 carburetor engines. It allows you to create carburations with all the information about the type of engine, track, weather conditions and carb setup (jets, needles, air screw, ...) making for each of them a simulation that allows you to compare them, choose a carburetion as a reference to be able to adapt it in each situation, take notes, check how each change in carburetion affects, etc. The carburations can be manually made or the app can provide you a optimal recommendation based on all the information for the following engines: - Rotax Max Senior, Junior, DD2, Supermax, Mini (with different restrictors) and Micro (with different restrictors too). Evo and no-Evo engines are compatible, and the recommendations follow the technical rules of Rotax Max Challenge competition. - Aprilia RS 125 and equivalent engines like Rotax 122 and 123. The application consists of several screens and features: - Simulation main screen: it shows the graph and the values of the configured carburations. One of the carburations will be marked as a reference to make comparisons on this configuration. For each carburetion you can edit its value or create new ones. - Setup creation or edition screens: when creating or selecting a carburetion on the main screen the user is guided by a set of screens on which he can provide information about the engine (brand, model, fuel density, % oil mixture), carburetor configuration (high, low, diffusers, needle, air screw, jets, etc.), weather conditions (temperature, humidity, altitude, pressure... that can be picked up automatically), and the track (name, length, lap time, maximum speed, etc.). - A functionality to collect the weather conditions of the nearest weather station: get the temperature, atmospheric pressure, humidity, altitude, air density, altitude by density and more values. - Help on each screen, preferences to modify the language, appearance or available parts, etc. The application has been tested by international racing teams, but can be used by anyone to optimize their engine.

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.
