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.

Listen to Live NOAA Broadcasts with Rewind & Replay. Listen to available NOAA Weather Radio All Hazards broadcasts and review recent audio with Rewind & Replay. Station availability and audio quality depend on the stream provider and your internet connection. Stay Safe. Stay Informed. Stay Ahead. Receive supported weather alerts when notifications are enabled, including when the app is closed and your screen is locked. Delivery and timing depend on your notification settings, connectivity, Apple services, and upstream weather data. The app should not be your only source of emergency information.

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.
Hypothesis 1
Enhance location services for better coverage.
Assumption to check: Limited geographical coverage for alerts
Validate with people who use this workflow before building.
Hypothesis 2
Simplify settings with clearer options.
Assumption to check: Complicated settings for notifications
Validate with people who use this workflow before building.
Hypothesis 3
Implement adaptive streaming for better audio quality.
Assumption to check: Inconsistent streaming quality
Validate with people who use this workflow before building.
Hypothesis 4
Modernize the UI with updated design guidelines.
Assumption to check: User interface can feel outdated
Validate with people who use this workflow before building.
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.
