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.

Packr is the packing list that thinks for you. Tell it where you're going and for how long, and Packr builds a tailored checklist — scaled to your trip length, adjusted for driving vs. flying, and shaped by your own reusable defaults. Check things off as you pack, and the list gets out of your way. WHY PACKR • Smart lists that scale — a 3-night trip and a 10-night trip get the right quantities automatically. • Weather-aware — see a day-by-day forecast for your destination and get nudges (rain jacket, warm layers, sunscreen) baked right in. • On Plane Kit — flying? Packr adds a grab-from-your-bag seat kit so your headphones, charger, and snacks are never buried. • Your defaults, your way — customize the master list once and every future trip starts from it. Save add-ons like Motorcycle, Gym, or Beach. • Keep the paper trail — paste (or snap a photo of) a flight or hotel confirmation and Packr pulls the dates, times, and confirmation numbers into your trip notes. • Share a trip — send a travel companion your itinerary and they get their own list, built from their own defaults. • Not-packed filter — hide everything you've already packed and focus on what's left. Built for real trips, from weekend drives to two-week flights. Buy it once — no subscription.

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.
