Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
With dominant-colour AI, Color Picker Pro + is a studio-grade tool for designers, developers, photographers, and UI teams. Load any photo or video frame, magnify the target area, and capture exact colors with live HEX, RGB, and HSL readouts. Build palettes fast, name shades automatically, and batch export to your workflow in one tap. Accuracy first: Pixel-precise loupe with configurable zoom and crosshair alignment. Real-world results: Average-radius picker smooths noisy textures like skin, grass, and fabric. Instant palettes: Detect dominant colors from the full image or a region. Frictionless export: Export HEX list, CSV, JSON, and a PNG palette strip. Copy as CSS variables or Swift initializers. Video support: Scrub to any frame and sample in place. Undo/redo & history: Iterate without fear. Revisit any pick. Offline and private: All processing happens on the device. No accounts. No tracking. Made for iPhone and iPad: Responsive layout, keyboard shortcuts, haptics, and iPad pointer support. Dual-mode sampling: Single-pixel precision plus adjustable averaging radius for consistent brand colors. Dominant-color engine: Finds balanced, non-redundant palettes that print and display well. Human-readable names: Automatic naming to speed communication with clients and teammates. One-tap exports: Share as JSON, CSV, HEX list, or a ready-to-use PNG palette bar for specs and mood boards. Workflow details that matter: Undo/redo, clear, zoom presets, palette lock, and quick add. Pick Photo or Pick Video. For video, choose the frame you want. Move the loupe to target a pixel or set an Avg r radius to sample an area. Tap Add to save the color. Repeat to build a palette. Use Dominant for instant auto-palette. Export as JSON, CSV, HEX, or PNG, or copy CSS/Swift snippets. Built for professionals Color spaces: HEX, RGB, HSL Palette size control and duplicates merge Color naming and accessible contrast readouts (WCAG guidance in tooltips) Works fully offline; ideal for confidential assets

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
