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.

DATA SOURCES Forecast and alert information is provided by the National Weather Service. Tide, water-level, current, wind, and water-temperature products are provided by NOAA Tides & Currents. Buoy observations are provided by the NOAA National Data Buoy Center. Values may be converted to the units selected in WaveBrief and rounded for display. Data availability varies by location, station, and source. WaveBrief is independently developed and is not affiliated with or endorsed by NOAA, the National Weather Service, the National Data Buoy Center, or the United States Government. INFORMATIONAL USE Marine forecasts and observations may be delayed, incomplete, estimated, or unavailable. Conditions can change rapidly. WaveBrief is provided for general planning and informational purposes only. It is not a substitute for official warnings, local authorities, required navigation equipment, seamanship, or professional judgment.

PRIVACY WaveBrief does not require an account and does not use personal data for advertising, analytics, profiling, or cross-app tracking.

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.
