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
Some days are sunny. Some are stormy. Inner Forecast is a calm, private way to notice which one you're having. Checking in takes a moment. Choose the weather that fits how you feel, set how strongly it feels, and add a few words if you want to. Over time, a gentle picture of your inner weather forms, yours to look back on whenever you like. What's inside: Six weather moods, from Stormy to Sunny, with how strongly each one feels. A journal for days that need more words, and Look Back for entries worth returning to. A simple way to see how your week really moved, day by day. Home Screen widgets for your forecast and a daily lift. A First Aid Kit for hard moments, with breathing, grounding, and support links when things feel heavier. Make it yours. Arrange the app around how you think, build your own theme, and write your own affirmations. Private by default: Everything stays on your device. No accounts, no trackers, nothing uploaded. No ads, no subscriptions, no data selling. Forever.

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.
