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.

A beige sedan. An aqueduct. A newspaper stand. Telephone wires. Station announcements. Snippets of conversation. All captured on January 7, 1993 by a college student riding the Amtrak San Joaquins through Central California with his VHS-C camcorder, on the way back to his last semester at school in Los Angeles. 95 MOMENTS ON A TRAIN assembles every moment of the footage and combines it with a propulsive FM synth score written at the time, for a short film that was never made until now. The result is a time capsule of the 1990s, a collision of grunge video with modern devices and split screen — plus the ability to remix the film yourself in endless ways. Choose the shots and layouts, the frame rates, colors, and effects, and use your own music as the soundtrack. Add your own poetic or meditative text and slap it on top of the footage with masking tape. Or just set the sleep timer and let the sounds of the rails coax you to a nap. • A meditative VHS time capsule from the 1990s, filmed on a single day • Includes a original FM synth score written for the film • Featuring optional random journal fragments from the time • Fully dynamic — never plays the same way twice • Remix the film with a range of audio, video, content, layout, and frame rate options • Includes twenty preset variations on the film • Audio options let you use your own music as the soundtrack • Add your own poetic text as masking tape labels on the footage • Sleep timer lets you fall asleep to the sounds of the rails • Autoplay feature plays the film on its own

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.
