Generating… usually about a minute.
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.

This Living Worlds app is a modern recreation of a set of dynamic pixel art scenes first published in the early 90s as part of an "illustrated personal organizer" named Seize the Day, and seen as screenshots across the Internet since then. These scenes were created by Mark Ferrari, legendary artist from such classic games as Loom and The Secret of Monkey Island as well as the recent Thimbleweed Park. Now, 25 years later, Ian Gilman, the original software developer, has resurrected the Living Worlds, with Mark's support and additional code from Joseph Huckaby. There may be copycats, but this is the only authentic version from the original creators! This release of the app contains all twelve of the original scenes in their full glory. The sun rises and falls in real time, storms pass through, flowers bloom, the moon and stars cross the sky. Smaller details like chimney smoke and animal footprints come and go. The image "lives" throughout the day, drawing you in, suggesting stories, and rewarding quiet observation. In addition to the classic graphics, each scene includes a new "Logbook" story written by Mark Ferrari and ambient soundscapes designed by Ian Gilman. Join us for this 25th anniversary celebration of these unique artworks!

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.
