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
Purge is the most advanced porn blocker that does device level blocking. You can use any browser including Safari, Chrome, Firefox. This is not just Safari content blocking, this is device level protection like you have never seen before. Protect yourself and your family and purify your soul with this most essential app. This is a must-have for every parent looking to protect their child. NOT JUST BLOCKING You and family won't even be exposed to adult content. For example when doing a Google or Bing search you will automatically get family friendly safe-search results for text, images, and videos. Not only that you get safe results in YouTube as well, you don't have to worry about your kids watching inappropriate videos on YouTube again either. SEAMLESSLY INTEGRATION The app works in the background without any significant battery usage. What you will see is an increase in speed of your browser and your family protected. ON-DEMAND This will allow the app to always stay connected. PASSCODE PROTECTION Keeps yourself or kids from disabling with a passcode and restrictions. You can also stop people from deleting the app with a passcode using the iOS restrictions settings on your device. Let your accountability partner setup a passcode for you. [Accountability Partner should go to iPhone/iPad Settings > General > Restrictions > Enable Restrictions and set "Deleting Apps" switch to Off] PROTECT YOUR KIDS Install the app on your all your devices and know that your loved ones are being protected. AUTOMATED ALERTS Get email notification incase the app is turned off for any reason. Get nightly logs for all DNS requests as well if you want. If you find inappropriate content, that is not blocked, please use the in-app email system or email us directly and we will dynamically update the list and you can update your app list with "Update Purge Blocker" button in the app. Feel free to email as well at [email protected]

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.

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.
