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
Check Ledger is a local check management tool for finance staff, cashiers, administrative offices, and small businesses. It helps record check issuance, use, payment, voiding, and handover details. The app requires no login, does not connect to the internet, and does not collect user data. Check numbers, amounts, handlers, due dates, and notes are stored locally on your device. It is suitable for offices that still use paper checks and need clear handover records and due reminders. Core features include check files, use registration, payment and due tracking, void and stop-payment records, number search, handover reports, and offline export to reduce missed entries, errors, and unclear handovers.

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
Implement cloud sync options for data security.
Assumption to check: Limited offline functionality and no cloud backup
Validate with people who use this workflow before building.
Hypothesis 2
Create a modern and visually appealing UI.
Assumption to check: User interface may feel outdated
Validate with people who use this workflow before building.
Hypothesis 3
Add comprehensive reporting tools for better financial insights.

Validate with people who use this workflow before building.
Hypothesis 4
Enable sharing of transaction details via social media or email.
Assumption to check: No sharing features for transactions
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.
