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 solid, old-school tower defence design where every map makes you stop and think about the best strategy." – Touch Arcade (App of the Week) "2112TD takes the classic Westwood RTS art style and blends it with tower defence — and it works brilliantly." – Pocket Gamer (Game of the Week) Set 100 years in the future, battle inter-dimensional flesh spawn across the solar system and defend Earth's colonies from complete annihilation. The pace is steady, but the stakes are high as the relentless hordes amass in an effort to overrun your mobile command center. Unlike traditional TD games, you will be relying heavily on micro-managing dynamic action-based abilities. As you progress deeper into the campaign airstrikes, charged attacks, fortification walls and the tactical drone will become increasingly vital and deploying them strategically will be paramount. Mistakes won’t go unpunished so stay frosty, learn from your blunders and endure to fight another day. Without pain there can be no gain! **FEATURES** BEAUTIFULLY ILLUSTRATED ENVIRONMENTS AND GRAPHICS 2112TD’s artistic style is founded on the nostalgia of the RTS golden era, paying homage to games like Command and Conquer and StarCraft. A CAMPAIGN TO TEST YOUR SKILLS The battlefield is an unforgiving landscape and every second counts. Beginners will find forgiveness on normal mode while veterans will be drawn to the challenge of hard. When you’re ready it’s time to put your skills to the test in nightmare and survival. How long can you hold back the hordes? BURN, BLAST AND OBLITERATE Deploy the machine gun, flame thrower, artillery and plasma turrets to destroy your foes. Upgrade your towers to their experimental stages packing serious firepower and charged attacks. DEATH FROM ABOVE When the situation gets too hairy you’ll be relying on air support. The airstrike and tactical drone deliver the big BOOM as well as defensive abilities. RESEARCH TO VICTORY Earth’s egg heads are working tirelessly to gain the upper hand against the new enemy. Unlock new abilities and weapons as you progress. DISCOVER AND DOMINATE They call it the soldier’s dictionary. The tactical database gathers data on the battlefield about your arsenal and enemies alike. Be sure to check it often as it will be critical to your triumph against the hordes. ACHIEVEMENTS & COMBAT STATISTICS Commanders that excel on the battlefield will unlock achievements as a reward for their contributions in the struggle against the invaders. What are you waiting for commander? The flesh spawn must be eradicated! --- 2112TD contains no in-game advertisements or micro-transactions. Got feedback?

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.
