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.

The beep test (also know as the multistage fitness test, bleep test, pacer test and shuttle run test) is a standard fitness test used by professionals to test cardiovascular fitness. The beep test involves running back and forth between two markers at 20m (6.5′ 7.4″) apart at an increasing pace as indicated by audio beeps. Your fitness level will then be calculated based on how long you can keep the pace. An audio beep and visual cue will indicate marker and stage changes. The Beep Test is a standard fitness test used by Sporting Teams (including but not limited to soccer, football, Australian Rules AFL, hockey, rugby, cricket, athletics and tennis). The test is also and entry requirement for Police, Fire and Emergency Response, Army, Air Force and Navy. Check out www.beeptests.com for more information or contact us for any questions.

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.

Intermediate
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.
