A product spec, screen plans, and build steps for your coding agent.

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.

"Learning Chinese is very probably the most rewarding single investment that a student of East Asian medicine can make." - Nigel Wiseman and Zhang YuHuan The Chinese Medical Characters app is a tool to learn the foundational terms and concepts of Chinese medicine. The app allows users to search the dataset by translation, Pīnyīn, or Chinese character. This feature enables the user to quickly understand the different translations of common Chinese characters they encounter in medical textbooks or other references. For example, a user can easily determine that the Chinese medical term translated variously as "deficiency" or "vacuity" or "emptiness" is actually a single Chinese medical term: 虛Xū. This knowledge allows the user to avoid confusion when referencing texts from different translators. In order to increase fluency in Chinese medical terms, the app has a built-in character test. The test allows users to practice recognizing traditional or simplified characters and matching them with their correct Pīnyīn and English translations. Correct answers on the test reveal the common acupuncture points, herbs, formulas, and concepts in Chinese medicine that include this character. The user can select from different categories to test, such as Theory, Anatomy, Acupuncture, Herbal Medicine, Vital Substances and others to focus on, or the user can access the whole dataset at once. All progress made in mastering each category is recorded and displayed. Finally, users can test their character retention by writing each character. To help with this challenging section, the user can temporarily display the character and review its proper stroke order before proceeding. Like the reading section, the user can select from different categories, such as Theory, Anatomy, Acupuncture, Herbal Medicine, Vital Substances and others to focus on or the user can access the whole dataset at once. All progress made in mastering each category is recorded and displayed.

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.
