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.

Introducing Ciro Marchetti’s Fin de Siecle Kipper! Kipper cards are a cartomancy deck long cherished in Germany. Like the Lenormand, Europeans have been reading with Kipper decks since the middle of the 19th century. Now Ciro Marchetti has created a contemporary heir to the Kipper tradition, accompanied by card meanings from three expert Kipper readers. Ciro’s elegant interpretation retains the cards’ antique charm, while expanding the deck’s focus with three supplemental cards. Fin de Siecle Kipper cards speak to human experience across all echelons of society. Set in Victorian England, here you will find the story of the workers as well as the wealthy. Ciro’s lavish images remain true to Kipper’s core message, while addressing darker aspects of life during the early Industrial Revolution.

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.
