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.

KEY FEATURES: ALL-NEW: BIRD ID It's now easier than ever to identify a bird you just saw. Enter all you were able to observe—what color was it? How big? What did its tail look like?—and Bird ID will narrow down a list of possible matches for your location and date in real time. LEARN ABOUT THE BIRDS YOU LOVE Our field guide features over 3,000 photos, over eight hours of audio clips of songs and calls, multi-season range maps, and in-depth text by leading North American bird expert Kenn Kaufman. KEEP TRACK OF ALL THE BIRDS YOU SEE With our completely redesigned Sightings feature, you can keep a record of every bird you encounter, whether you're hiking, sitting on the porch, or simply catching a glimpse of birds out the window. We'll even keep an updated life list for you. EXPLORE THE BIRDS AROUND YOU See where the birds are with nearby birding hotspots and real-time sightings from eBird.

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.
