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
Noxyl keeps route translation, checkpoint posting, route cards, and credit-based tools in one controlled flow. Start a voice relay when a spoken note has to stay readable, switch to text translation when you only need a quick phrase, and pin the right checkpoint before you publish a route update. Build route cards from saved locations, keep profiles, feeds, and follow lists organized around active trips, and use credits for route cards and voice relay actions when you need richer travel output. Noxyl is built for travelers who need clear movement between local notes, visual updates, and saved travel content. Use location-based features to tag where a route moment happened. Publish posts when a checkpoint is worth sharing. Camera, microphone, and photo library access support route media capture, spoken note relay, and saved travel visuals inside those flows.

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.
