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 Aircraft is a mini encyclopedia of the most important and influential aircraft that were used during the Second World War. This pocket compendium app contains 240 aircraft and lets you explore: - the evolution of aircraft design, from the post-WWI Po-2 and R-5 biplanes to the Meteor jet fighter, - the advancements in combat aircraft (from the CR.32 to the Ta 152), heavy interceptors (like the Do 335 Pfeil and the P-38 Lightning) and night fighters (including the P-61 Black Widow and the Defiant), - the development of the bomber, from the Blenheim light bomber and B-10 medium bomber to the Lincoln heavy bomber and the jet-powered Ar 234 Blitz, - the creation of specialized ground-attack aircraft (Il-2 Sturmovik and Hs 129), dive bombers (Ju 87 Stuka, SBD Dauntless and D3A), torpedo bombers (from the Swordfish to the Albacore), reconnaissance aircraft (like the Fw 189 or Ki-46), liaison aircraft (Lysander and Bf 108 Taifun) and trainer aircraft (T-6 Texan or Tiger Moth), - the rapid growth in size and capability of the flying boat (from the interwar MBR-2 to the famous PBY Catalina and ending with the gigantic BV 238), - the birth of the military helicopter (in the form of the Fl 282 Kolibri and Fa 223) and - the replacement of civilian service transport aircraft with purpose-built military troop and cargo airplanes (including the C-47 Skytrain, Ju 52, SM.82 Canguro or Me 323 Gigant) and gliders (like the DFS 230 or the Horsa). Each aircraft entry contains at least one archive image, a short text that summarises the aircraft's development and service history and a detailed specifications table offering place of origin and production information, crew, weight and dimensions data, 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.
