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

Trail Treker is a map viewing tool for use with the Trail Treker map publishing service. Trail Treker works with clubs, tourism agencies and municipalities to make their maps work offline on end user smartphones. Once the map is loaded, you no longer need phone service; the GPS receiver in your phone will operate without phone service. In fact, we recommend that you place your phone in Airplane Mode if you are in an area with limited or partial phone service to conserve your battery. Trail Treker will also electronically, via GPS location, show local businesses and points of interest. You can store your own points of interest as well. Key points such as survival shelters, supplies, or emergency evacuation points may be shown on various maps. The Trail Treker app will allow you to download any member map. If you have a member map code, the map will be free. If not, the map will be an additional purchase. Continued use of GPS in the background can decrease battery life. FEATURES: Show Trail map overlaid on various Google maps (Standard Street, Terrain, Satellite) Show your position on top of any map. Record your position and tracks Record notes regarding position points Share your saved positions or tracks with others See local businesses on or near mapping area Filter local businesses by category Load and layer up to two maps concurrently and any number of tracks. Load any number of maps (storage space required)

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.
