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
Unveil the world with our revolutionary app, powered by Apple’s state-of-the-art Create ML technology. Dive into the fascinating realm of flags, with a machine learning model meticulously trained on around 4,700 flags from 193 countries. Just point, scan, and discover! Key Features: • Instant Flag Identification: Effortlessly scan the flag of any country to identify it on the spot. • Accuracy at a Glance: Instantly see the confidence level of each analysis. • Explore an interactive world map to locate the country of the flag. • Dive Deeper: Explore each nation further by viewing its Coat of Arms. Our app is built on the most up-to-date information, sourced from the world’s largest knowledge base - Wikipedia. It’s designed to deliver cutting-edge analysis in a way that’s intuitive, engaging, and visually stunning. Important: While our app is an incredible educational tool, it’s not a substitute for official flag interpretation. The developers bear no responsibility for any decisions or outcomes based on its use. This version is more dynamic and inviting, with a focus on engaging the reader and highlighting the app’s features in an exciting way.

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 with user submissions or a larger database
Assumption to check: Limited flag database may not cover all flags
Validate with people who use this workflow before building.
Hypothesis 2
Implement better low-light detection and enhancements
Assumption to check: Camera functionality may struggle in low light
Validate with people who use this workflow before building.
Hypothesis 3
Allow users to share identified flags on social media
Assumption to check: No social sharing features
Validate with people who use this workflow before building.
Hypothesis 4
Create a guided tutorial for first-time users
Assumption to check: User onboarding may be unclear
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.
