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.

River Ready puts real-time river conditions in your pocket. Flow, clarity, water temperature, and weather for 10,000+ USGS river gauges across all 50 states and Washington, D.C. — before you make the drive. A river doesn't post its own conditions, and neither does the sky. Rain upstream can turn a clear run to mud in an afternoon. Snowmelt spikes the flow. A cold front drops the water and shuts the hatch off. River Ready makes checking the water one tap — on any gauge, anywhere. EVERYTHING THE RIVER CAN TELL YOU • Flow — gauge height and discharge in feet and ft³/s, with trends. Is it wadable, or blown out? • Clarity — turbidity read as clear to muddy. The honest answer to "can I see my feet?" • Water temperature — with the trend, so you know when the fish move and the hatch is on • Weather — current conditions, an hour-by-hour forecast, and a 5-day outlook for every gauge THREE TAPS TO THE WATER 1. Open the map — every USGS gauge in the country, or search by river and place name 2. Tap a gauge — flow, clarity, temperature, and weather for that exact stretch 3. Read the water — trends in the gauge's own timezone, in feet and ft³/s Built for anglers, paddlers, and anyone who plays on moving water. Know the river before you make the drive. River Ready USA is not affiliated with the U.S. Geological Survey. Gauge data is provided by USGS and subject to its availability and terms.

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.
Not assessed in a Build Kit yet.
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.
