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.

World War II Military Vehicles is an encyclopedia of the most important and influential vehicles that were used during the Second World War. This pocket compendium app contains over 320 vehicles and lets you explore: - the evolution of tank design, from the post-WWI Renault FT to the T95/T28 of 1945, - the development of the armoured car, from the Czech Skoda PA-II to the German 8-wheel Puma, - the creation of specialized tank destroyers (from the makeshift Marders to the agile M18 Hellcat), assault guns (StuGs and KV-2), self-propelled artillery (from the Soviet Katyusha to the American M40) and anti-aircraft systems (like the Ostwind or 40M Nimród), - the increased use of engineer vehicles (from Hobart's Funnies to the remote-controlled Goliath), - the birth of the infantry support vehicles, in the form of tankettes (TKS and Type 94), half-tracks (Sd.Kfz. 9 Famo) and armoured personnel carriers (Kangaroo) and - the replacement of civilian service vehicles with purpose-built military light vehicles (including the Kübelwagen, the Matador, the DUKW and the Universal Carrier). Each vehicle entry contains at least one archive image, a short text that summarises the vehicle's development and service history and a detailed specifications table offering place of origin and production information, crew, weight and dimensions data, armour and armament details, powerplant and performance figures.

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.
