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.

From the creators of Spirit Story Box, the ER70 EVP Recorder emulates a discontinued vintage physical digital recorder which is famous for capturing Electronic Voice Phenomena (EVPs). The ER70 EVP recorder is for entertainment purposes only. Here are some key features: • Legendary Signal Path: Replicates the signal path of a famous 1990’s digital recorder which currently sells for thousands of dollars on online auction sites • 3D styling: inspired by the aesthetics of original device, the ER70 is dynamically rendered in realtime, and set against 360º photographs of haunted and scenic locations • Physical Based Rendering (PBR): Lighting and reflections change as iPhone is rotated • Simple operation: Easy to use, difficult to mess up • Voice Activated System: Let the app automatically record audio changes. Watch for the blink! • Seven Minute Sessions: The ER70 limits sessions to seven minute intervals. No more searching through hours-long recordings • Tagging: the ability to log where in a recording an anomaly can be heard • Easy saving and sharing: How many files get stuck on your physical digital recorder? • 5-second skip and rewind: It shouldn't be difficult to quickly review a file with your friends. • Optional Geolocation: Have you ever recorded a file and later wondered where the EVP session took place? • Favoriting: You should be able to identify your best recordings at a glance. • Easy file renaming: Renaming a recording is as simple as slowly tapping twice on a file name. • Accessibility features: For persons with disabilities Instead of heavily investing in a used piece of gear which is destined to wear out, why not spend a fraction of that on an app which offers so much more?

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.
