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.

Reference Board is a private visual workspace for collecting inspiration, developing ideas, and keeping creative research close at hand on Mac, iPhone, and iPad. BUILD VISUAL BOARDS • Collect images, videos, links, text, colors, and PDFs in one place. • Arrange references freely on an infinite canvas or switch to an organized grid. • Move, resize, group, stack, crop, flip, and annotate without changing your original media. • Use the loupe to inspect fine details in images and videos. FIND WHAT YOU NEED • Search across boards and references. • Use on-device analysis, OCR, colors, metadata, and visual similarity to rediscover material quickly. • Keep notes and details attached to the work they describe. SYNC, COLLABORATE, AND SHARE • Keep your library in sync across Mac, iPhone, and iPad with iCloud. • Invite others to collaborate on shared boards. • Publish a separate public, view-only webpage when you want to present your work more widely. • Update or unpublish a published board whenever you like. WORK YOUR WAY • Import from Photos, Files, Safari, drag and drop, or the Share Sheet. • Export boards as images, PDFs, or Reference Board archives. • Use widgets, Shortcuts, the screen saver, and optional MCP automation to connect Reference Board to your workflow. ONE PURCHASE. NO SUBSCRIPTION. New customers receive Reference Pro with their App Store purchase, including unlimited private boards and items, Publish to Web, AI metadata and visual discovery, new collaborations, PDF export, and MCP automation.

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.
