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.

Hypothesis 1
Introduce advanced features like project timelines and collaborative tasks.
Assumption to check: Limited task management features compared to competitors
Validate with people who use this workflow before building.
Hypothesis 2
Allow user customization of AI suggestions based on preferences.
Assumption to check: AI suggestions may not always be relevant
Validate with people who use this workflow before building.
Hypothesis 3
Implement offline task management with sync capabilities.
Assumption to check: Lack of offline functionality
Validate with people who use this workflow before building.
Hypothesis 4
Simplify the pricing structure and clarify the benefits of each tier.
Assumption to check: In-app purchases can be confusing
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.

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.
