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
Connect. Play. ShowPlay connects to entertainment networks to remotely trigger video, audio, images and colours, and simulate incoming calls and messages using OSC (Open Sound Control). It is the ideal solution for theatre, movie, TV and event production. Import media from the local device, or synchronise with Dropbox cloud storage. ShowPlay actively re-establishes connections on weaker networks, and provides easy to access logs of incoming messages for troubleshooting. Video Play video files, and control audio levels and looping behaviour. Audio Play audio files, and control audio levels, speakers and looping behaviour. Images Display images, and control stretching behaviour. Colours Display colours by providing RGB values. Call Simulate incoming calls, and control ring/vibrate behaviour and caller identification text. Message Simulate incoming messages, and control ring/vibrate behaviour and messenger identification text.

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.
