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
Tired of Google’s AI-powered "Overview" panel cluttering your search results? Smpl is a lightweight Safari extension that restores the classic Google Search layout and fixes common annoyances. No more confusing AI summaries or distracting suggestions. Key features: - Disable Google’s AI Overview and extra suggestions. Tap the "All" tab to view other Knowledge Panels when needed. - Automatically open search results in a new tab. - Hide trending searches from Google's homepage. - Automatically open Reddit links in Narwhal. - Hide the Reddit login prompt on the mobile website. - Redirect X/Twitter links to XCancel. How it works: - Install the app and enable the Safari extension. - Open the extension popup and toggle the features you want to use. - Conduct Google searches as usual. - Smpl adds a URL parameter (udm=14) to send searches directly to the Web tab, bypassing the AI Overview. - Tap “All” anytime to view Knowledge Panels (weather, quick facts, etc.). Smpl is built and maintained by a solo indie developer, ensuring it stays lightweight, reliable, and up-to-date. If you love Smpl, please consider leaving a rating or review. For questions or feedback, tap the Contact link within the Smpl app.

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.

BUILD KIT DIFFICULTY
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.
