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
TSA Wait Times helps you plan smarter airport departures with security wait estimates, source and confidence labels, favorites, reminders, and a personal flight planner. WAIT ESTIMATES WITH SOURCE LABELS Search US airports by city, code, or name. Each result shows Standard and TSA PreCheck estimates, terminal-level breakdowns where available, source quality, confidence, and when the estimate was updated. ATL, BOS, BWI, CHS, CLE, CLT, CMH, CVG, DCA, DFW, DTW, ELP, EWR, GSP, HOU, IAH, JAX, JFK, LAS, LEX, LGA, MCO, MIA, MSP, ORD, PDX, PHL, PHX, PIT, PSP, SEA, SFO, SLC, and TUL include airport-published checkpoint data, with additional airports falling back to source-labeled planning estimates. FLIGHT PLANNER Enter your flight time, drive time, expected TSA wait, and extra buffer. The app calculates when to leave and breaks down the plan minute by minute. If you have already checked an airport's wait estimate, the planner can use that value automatically. FAVORITES Save your most-used airports for quick access. WAIT HISTORY Lookups are saved locally so you can review past estimates. You can also log your actual wait time to compare the estimate against your own experience. REMINDERS Schedule a notification before your calculated leave time so you remember to check conditions again before heading to the airport. TRANSPARENT DATA Version 2.0 separates wait times from their source. Estimates may be airport-published, historical, or modeled. The app avoids presenting modeled estimates as live TSA data. Always verify with TSA, MyTSA, your airline, or the airport before travel.

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
Intermediate
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.
