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.

Provide a straightforward offline maps download process.
Assumption to check: Offline navigation can be complicated to set up
Validate with people who use this workflow before building.
Hypothesis 3
Utilize high-quality TTS for clear voice navigation instructions.
Assumption to check: Voice navigation can be unclear or inconsistent
Validate with people who use this workflow before building.
Hypothesis 4
Focus on a clean and simple design to improve usability.
Assumption to check: User interface might be cluttered or confusing
Validate with people who use this workflow before building.

App Store description
The easy way to turn a Google Maps directions link into a routable GPX file! Map2Route takes as input a Google Maps direction link and outputs a GPX file which follows those directions. You can use this GPX file for routing in other apps, or on GPS tracking watches such as Garmin. It's easy to use because you can use the share function to directly send links to Map2Route.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
