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.

Your body, your data, your breakthroughs. Whether you're navigating a chronic condition, exploring food sensitivities, or simply striving for optimal wellness, RootCause equips you with powerful tools to track, analyze, and ultimately thrive. Equipped with cutting-edge AI technology, RootCause aims to transform how you think about what you eat in relation to how you feel. RootCause is a modern and well-thought-out approach to traditional food and symptom tracking, striving to actively engage the user with the data they input via advanced algorithms and AI-generated insights. Not only is RootCause the first-ever intelligent food and symptom diary, but it also provides users with innovative beta features like the Gut Map—the first interactive food/symptom directed force graph. Track what you eat and the symptoms you experience, and RootCause will extract correlation data based on the timeframe between when foods and symptoms are added and calculate the correlation between specific foods and symptoms. Using our algorithm, AI interprets the results to provide you with a clear interpretation of the correlation data, speculating on how the food and symptom could be related. The information provided by RootCause is for general informational purposes only and is not intended as medical advice. The app’s suggestions and data are based on user input and algorithms and are not a substitute for professional medical consultation, diagnosis, or treatment. All insights and personalized analyses are AI-generated and may contain inaccuracies. Always consult a qualified healthcare provider before making any health-related decisions.

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.
