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
Kiosk 27 is an iPhone camera app designed to capture the experience of a premium compact film camera. It features a sensor‑level RAW (Bayer) processing pipeline with a consistent 12 MP output, preserving fine detail and dynamic range while recreating an authentic analog look inspired by real film stocks. The live preview remains clean and natural for composition. Each shot is first processed as a film‑style negative, then rendered into a finished positive image, just like real film. What you can do: - Capture 12MP photos with sensor-RAW processing for reliable, consistent quality - Choose film-stock-inspired looks with texture-rich rendering (grain, bloom, halation-style highlights) - Shoot with practical tools: timer, flash, focus lock for fast shooting, date stamp, mist effect, and white-balance control - Compose faster with a 35mm frame guide for street shooting - Create double exposures in-camera - Work in rolls with frame progression and generate a roll-style contact sheet output - Save photos and contact sheets directly to your Photo Library - Track your active roll at a glance with a beautifully designed Home Screen widget Designed for focused shooting. No account setup. No subscription. No ads.

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.
