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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Save a trip to the lumber store by planning your project with precision. KerfMaker makes sure you get just enough wood for your woodworking project. Designed by a woodworker, KerfMaker has the tools you need to help keep your lumber costs low and your project together. With KerfMaker's project planner, you'll assemble a precise list of boards needed to get your project done – and make sure you only need to make one trip to the lumber yard or hardware store. “...easy to learn, very useful. Sorts my parts quickly. Worth the purchase!” - Esther85839350, App Store Review "Though this has potential in the shop, it’s in project planning and shopping where this [app] on a mobile device really could shine.” - Tim C., Popular Woodworking author ORGANIZE AND PLAN Pick your boards, plan your cuts and put it all in one place. Use the parts list to keep track of everything you need to assemble. Organize your projects with photos, and share existing projects with other woodworkers. SAVE MONEY ON SUPPLIES We’ll help make sure you’re buying exactly the wood you need to finish your project, so you’ll have less waste — and more money to put toward your next perfectly crafted project. Keep your own library of materials and prices based on your local store. SPEND LESS TIME SHOPPING Take KerfMaker to the store and check off your boards as you pick them up - you'll never find you missed any needed lumber again. EVEN MORE: • Our smart algorithm figures out how to cut your boards into parts • Your customized board cut plan accounts for kerf width and wood orientation • The materials summary shows cost and weight of your boards • Plan your project in imperial (inches, feet) or metric (millimeters, meters) measurement systems • Projects can include multiple materials and wood thicknesses • Edit price and density in the materials library • Board cut plans are zoomable, scrollable, and printable • Woodworking authors and instructors can easily share parts lists

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.

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.
