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.

The world is shrouded in crime. Cities teem with gangs, smuggling rings, and assassin syndicates — citizens live in fear. As the newly appointed police chief, you must start small and strategically expand a local precinct while safeguarding the city. Grow your reputation step by step: expand office space, establish new departments, streamline paperwork, recruit elite officers, and equip your team with top-tier gear to tackle increasingly complex cases. Transform a modest station into a prestigious law enforcement headquarters! 1. Design & Build Your Police HQ Build an empire of justice from the ground up! Freely arrange facilities such as interrogation rooms, holding cells, and armories to optimize investigations. Every brick you lay brings the city closer to order. 2. Recruit Officers & Upgrade Gear Assemble a dream team of elite officers to dismantle criminal schemes. Invest resources in advanced weaponry and vehicles to handle escalating threats. 3. Investigate Cases Strategically Intimidation or incentives? Choose interrogation strategies and adapt your approach to each suspect. As your caseload grows, you’ll face off against notorious criminals and deploy SWAT teams to bring them to justice! 4. Manage Inmates More inmates mean more federal funding, but they also require meticulous oversight. Classify inmates by risk level, assign them to segregated housing, and maintain vigilant patrols to prevent jailbreaks. 5. Crush Prison Riots Poor meals, cramped cells, or lax surveillance can spark violent uprisings. Mobilize rapid-response teams in riot gear to suppress them before they tank your reputation and funding! Key Features: Strategic Depth: Balance budget, reputation, and security in a dynamic crime ecosystem. Progression System: Evolve from a rundown precinct to a high-tech law enforcement center. Realistic Challenges: Adapt to gang wars, hostage crises, and corruption scandals. Can you bring the streets back from the brink? The city’s fate rests in your hands.

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.
