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.

Each high-quality, full-color clinical and dermoscopic image is presented with short history. Every case is followed by multiple-choice questions and three check boxes to test your knowledge of risk, diagnosis, and disposition. Turn the page, and the answers to the questions are provided in an easy-to-remember manner which includes the dermoscopic images being sown again. Circles, stars, boxes, and arrows appear in the image pointing out the important criteria of each case. FEATURES: • Cases involving the scalp, face, nose, ears, trunk and extremities, palms, soles, nails, and genitalia – many new to this edition • The concepts of clinic-dermoscopic correlation, dermoscopic-pathologic correlation, and dermoscopic differential diagnosis are employed throughout • Each case includes a discussion of all of its salient features in a quick-read outline style and ends with a series of dermoscopic and/or clinical pearls based on the authors’ years of experience • Key dermoscopic principles are re-emphasized throughout the book to enhance your understanding and assimilation of the teaching points • Two new chapters on trichoscopy and dermoscopy in general medicine • Updated material on pediatric melanoma, desmoplastic melanoma, Merkel cell carcinoma, invasive squamous cell carcinoma, and nevi and melanoma associated with decorative tattoos This app is very intuitive and easy to navigate, allowing you to browse the contents or search for topics.

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.
