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
The DateMetriX Dating App utilizes a sophisticated algorithm to forecast "personality compatibility" using psychology. In addition, the DateMetriX Dating App enables you to discover and connect with people who share your beliefs, passions, religion, or hobbies. DateMetriX also offers an opportunity to assess physical attraction by viewing the photographs of your matches. How DateMetriX Works? Our personality compatibility rating is based on the Jung/Myers-Briggs 16 personality types. This psychometric test has a long history of development dating back 100 years to Swiss psychiatrist Dr. Carl Jung and his book "Psychologische Typen" which translates to Psychological Types in English. This personality test was later updated by Isabel Briggs Myers and her mother Katherine Briggs. The formal version of the 16 personality types test is known as the Myers-Briggs Type Indicator® and is used primarily to help in organizational psychology. The DateMetriX Dating App, personality compatibility algorithm, can be used to predict personality compatibility between single people and couples. It works by assigning maximum compatibility scores for similar personality types and less compatibility with personality types that clash.

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.
