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 2
Include breed-specific information and variations.
Assumption to check: Lack of detailed breed-specific anatomy
Validate with people who use this workflow before building.
Hypothesis 3
Simplify subscription choices and provide better trial options.
Assumption to check: Subscription model complexity
Validate with people who use this workflow before building.
Hypothesis 4
Add beginner-friendly guides and tooltips for anatomy terms.
Assumption to check: Inadequate information for beginners
Validate with people who use this workflow before building.
App evidence
Original App Store material. Ratings and screenshots describe the existing app, not proof of demand for your version.
App Store description
An interactive visual reference with over 300 anatomical structures. Rotate the model, cut down through layers, or zoom in. Tap the labels to get details of each structure with audio pronunciation, text descriptions and a close-up view. This app covers the superficial landmarks, superficial and deep muscles, bones, and organs. Quiz yourself on each section, make your own quiz, or have the app quiz you on just what you missed. If you want to understand canine anatomy, this app is for you.

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.
