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
Code Red is a navigation tool for understanding her monthly cycle. Made by men, for men. Think of it as a compass for emotional terrain—helping you understand where you are, what the conditions are like, and how to move through each day with a little more ease. WHAT CODE RED DOES Daily Positioning See where you are in the cycle, understand today's conditions, and get practical guidance on what she's likely experiencing and what you should (or shouldn't) do. **Phase Intelligence Understand the five distinct phases of the cycle and how each one affects mood, energy, and connection. From challenging days to peak opportunities—you'll know what to expect. GROUNDED IN SCIENCE Code Red translates mood and energy shifts into practical insights. No medical jargon. No overthinking. Just clear guidance from someone who's been there before. You'll know when conditions are favorable and when the terrain gets rough. NOT EVERY DAY IS FOR PROGRESS Some days are for safe passage. Code Red helps you recognize which is which. Navigate smarter. Not harder.

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.
