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
golnar transforms the way you see a handmade Persian rug. Ever held a rug and wondered where it came from, who made it, or what its patterns mean? golnar gives you the knowledge to find out. ◆ IDENTIFY ORIGINS Learn to recognize rugs by region, from tribal nomadic weavings to the great weaving cities of Iran. ◆ DECODE MOTIFS Discover the meaning behind symbols, flowers, animals, and geometric patterns woven into every rug. ◆ UNDERSTAND MATERIALS Explore wool, silk, and cotton and what they reveal about a rug's quality and origin. ◆ MASTER TECHNIQUES Learn knot types, weaving structures, and the craftsmanship that separates an extraordinary rug from an ordinary one. ◆ TEST YOURSELF Take the built-in quiz and discover how much you really know about Persian rugs. Whether you just inherited a family heirloom, bought your first antique rug, or have admired Persian rugs for years, golnar is the mentor in your pocket you never had. Beautiful, visual, and crafted with the same care as the rugs it celebrates.

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.

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.
