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.

The Perpetual Calendar of 100 Years (Three Languages Calendar of 100 Years) method included years, months, and days that were a system of uniting the Heavenly Stems and early branches. I combined one of the 10 Heavenly Stems 天干 (Tiāngān) with one of the 12 Earthly Branches 地支(Dizhi ) to form 60 unique pairs in a complete cycle. The years are organized into 60-year calendar cycles, five times the 12-year Chinese zodiac cycle. Similarly, the months and days are similar, five times the 12 zodiac animals' cycle. The zodiac system has existed in Chinese culture since the Qin Dynasty, more than 2,000 years ago. Over time the zodiac system became more integrated into everyday life, with different meanings and characteristics assigned to each animal for users to find auspicious days. The Perpetual Calendar of 100 Years, I included solar and lunar calendar systems that people can easily use to choose an auspicious day for personal and business activities. Selecting an auspicious day is based on the lunar and Gregorian calendars. The Gregorian calendar shows the date, and the lunar calendar indicates what date is an auspicious day. An auspicious day is a good day, mainly when good things are likely to happen. It is usually said about a day that opens up a new future or might open up a new future. People can use the Perpetual Calendar of 100 Years by using their birthday to find auspicious days. Especially for their marriage, wedding, engagement, grand opening, business official opening, signing contracts, residential relocation, ground-breaking, church ritual, temple ceremony, funeral, burial, tomb removal, tomb repair, significant surgery, traveling, door adjustment or replacement, bed adjustment, bathroom repair, kitchen repair, and other activities. People would like to look for an auspicious day for traditional cultural, religious, or psychological reasons.

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.
