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
Keep your network under control with Nice Trace - the most advanced traceroute app for iOS. The tool traces the route to the host in the Internet using easy, user-friendly interface and animations. You will immediately get information about any possible bottlenecks and problems since Nice Trace never stops working. It continues to monitor the whole path to the network resource in real time and keeps you informed. The specially designed asynchronous algorithm lets Nice Trace quickly pass through problematic hops not hanging on them, thus increasing the speed. Now you can reach the destination host fast like never before. FEATURES - Real-time path monitoring with packet loss detection - Easily spot possible network bottlenecks - Country of origin detection of the network owner - Network range and AS number lookup - WHOIS hostnames, IP addresses, ASNs - E-mail trace results - Ultrafast asynchronous network I/O Displays hops information (when available): - IP address - Reverse hostname (PTR DNS record) - Autonomous system (AS) number - Country of the network owner - Average packets round trip time (RTT) - Counts of packets that were sent and received - Percentage of the packet loss - IP network range (in hop details) - Other hops IP addresses and hostnames (in hop details) DEMO VIDEOS http://j.mp/nicetrace_vids MORE GREAT APPS · Spyglass - augmented reality & GPS navigator · Scany - Wi-Fi/LAN network scanner

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.
