A product spec, screen plans, and build steps for your coding agent.

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.

Graphical tide display on your Apple Watch, iPhone and iPad. The watch app displays a tide graph and highs/lows for the day and allows selection of any location configured on the iPhone app. Several watch complications are provided to allow display of tide level and direction at a glance on any Apple watch face. Enable time travel to see the tide level at any point in the day. On the iPhone an interactive tide graph is displayed by turning your device to landscape mode. Then touch the screen to see the tide at any time in the 24 hour window. No network connection is required, so you can check anytime, anywhere. New on iPad you now see a month-to-month tide calendar. Use it to easily plan your beach activities a month or more in advance. Allows navigation through the coming months or backward if you want to see what the tide was on a past beach visit. Runs on the current XTide 2.x codebase. This adds thousands of U.S. tide locations and currents. Current prediction is now supported for some locations within the U.S. only. Currents must be enabled in the application settings menu. We have also added the ability to configure the number of days of tides to display from one to fifteen days out. Tide station selection has been improved. Stations can be selected either from a map or from a list view arranged by country and state or province. ----------------------------------------------------------------------- *** Regarding Tide Station Locations and Currents *** ShralpTide2 contains a wealth of tide and current information for the United States thanks to the NOAA. At present the NOAA is the only provider of data for current prediction. Prediction of currents is not available for countries other than the United States. Additionally, though tide station information is available for some countries outside of the United States, many tide stations that were previously available in the original ShralpTide are not available in ShralpTide2. ----------------------------------------------------------------------- Source code is available under the GNU General Public License.

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.
