Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Airbend Pro is a tool that will perform calculations for bending precision sheet metal on modern press brakes. There are many apps for calculating standard sheet metal bending information, but what makes Airbend Pro unique is that it will provide bending calculations specifically for air bending. (Airbend Pro will also provide the standard bend information if the "Bend Type" is set to "Bottom Formed") Inputs: Material Type Material Thickness Bend Type Bend Angle Inside Bend Radius Bend Width V-Die Radius V-Die Width It will provide the calculated v-die width on the entry screen to help determine the proper V-Die Width Outputs: Actual Bend Radius Bend Deduction Bend Allowance Tonnage Setback Outside Setback Minimum Flange The results can be shared from the output screen. Math formulas are allowed on the entry screen Example 2.5 millimeters to decimal inches (2.5/25.4) 3 feet to decimal inches (3x12) 3/16" to decimal inches (3/16) Coming soon: 1. Reverse engineer bend deduction, bend allowance, and actual inside bend radius from a formed test coupon 2. Flat layout calculations and export to DXF. Any feedback or requests for additional calculations or information is greatly appreciated.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
