Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
FLINT (Fast Live Intelligence Network Tool) is an intuitive software that enables first responders to make tactical decisions en route to emergencies with visual based, mission critical data, including 360 degree dynamic building views, overhead hazards and working fire hydrants in a patented touchless format. ** VIEW 360° surroundings of the incident location. ** LOCATE & MANAGE the nearest in-service fire hydrant (covering 140+ municipalities). ** PRE-PLAN your life saving strategies before arriving on-scene. ** IDENTIFY hazards with our patented overhead flyover views. ** FIGHT EV FIRES efficiently with schematics at your fingertips (data provided by EV Rescue Inc). First responders love our touchless interface with CAD integration. When it's safe to remove protective gloves, an address search bar gives first responders the opportunity to provide mutual aid. Fire buffs, real estate agents, and insurance companies can also use the search bar to generate patented 3D flyover previews of virtually any address in the nation! For any technical support needs, please contact [email protected]. We are unable to respond to support issues posted as user reviews in the App Store. Location services note: Continued use of GPS running in the background can dramatically decrease battery life. CAD integration is required for first responder Enterprise-level users.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

BUILD KIT DIFFICULTY

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.
