What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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 professional successor to the best selling "Ghostalker", Ghostalker Pro detects the tiniest of vibrations and movement, converting that raw data into spoken words. This app has been built with a brand new engine for a more professional look and feel, but also making it very easy to use. Features include: + Uses the real, raw sensor data and does NOT choose words at random (like other apps). + Built-in dictionary of over 1000 common words. + Create custom word lists with up to 10,000 words each. + Create as many word lists as you like and switch between them instantly. + Choose to use either the built-in dictionary or one of your own word lists, or both combined. + Change the pitch and rate of speech. + Choose from many, many languages for the voice to ensure pronunciation is correct. + Download free word lists from within the app for different languages, popular names, verbs etc. (with more to come). + Constant automatic sensor calibration. + Copy and paste to and from custom word lists. + Copy from log files which are stored in TXT/CSV format to easily import into spreadsheets or documents. + Share log files with other apps, such as saving to cloud storage, sending by email and posting on social media. + No adverts and no internet connection required (unless you want to download word lists). INSTRUCTIONS: Place your device on a solid surface. It is designed to detect the smallest of vibrations and movement so DO NOT tap or shake your device as it will trigger words. Professional paranormal investigators believe that leaving such apps running for as long as possible will allow spirits to learn what energy is required to trigger certain words. This app is not designed to form complete sentences so it is up to you to interpret what it says in your own way. There are no adverts in this software and it does NOT require an internet connection (unless you want to download a new word list) so you can use it in remote locations. If the app does not do what you were expecting, or there is an issue with it running on your device, please contact me for help.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
