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.

Stop guessing what to pack. UPackIt looks at the weather where you're going, on the days you'll be there, and builds a packing list to match. Rain on Thursday? You'll get a rain jacket. Chilly nights and warm afternoons? Layers instead of one heavy coat. Strong sun? Sunscreen and a hat. Every suggestion comes with a short reason, so you know why it's on your list. HOW IT WORKS • Search for any city, region or country. • Pick your dates and the kind of trip: city, business, outdoors, beach — or a mix. • UPackIt checks the forecast and builds your list, sorted by category. • Tick items off as you pack. When everything's in the bag, your trip gets a checkmark. PACKING THAT FITS THE FORECAST • Daily highs, lows and chance of rain for every day of your trip. • Trips more than 10 days away use typical weather for that time of year, so you can start planning early. Refresh closer to departure and the real forecast takes over. • "Why this list" explains the big decisions — temperature swings, wet days, UV, trip length. PACK LESS • Turn on "Laundry available" and clothing is capped at a five-day rotation instead of one outfit per day. • Mixing trip types — say, a city break with a day of hiking — merges the lists so you don't pack two of everything. MAKE IT YOURS • Add your own items to any trip. They stay put when you refresh the forecast. • Save a list as a template and reuse it. Your template's items are added on top of the weather-based suggestions for your next trip. • Keep as many trips as you like, from this weekend to next summer. PRIVATE BY DESIGN • No account, no sign-up, no ads, no tracking. • Your trips and lists are stored only on your iPhone. • Temperatures and wind speeds appear in the units you use.

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.

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.
