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
TeX Go is a LaTeX editor for iPhone and iPad, built for writing, editing, compiling, and previewing documents wherever you are. Use it for equations, notes, reports, papers, and technical documents. TeX Go keeps the writing experience focused, with a clean editor, quick access to PDF preview, and tools that help you move smoothly from source to output. You can work with files stored on your device or in cloud storage, start from templates, and use editing support such as automatic bracket and command completion. TeX Go also supports local compilation, so many projects can be built directly on your device. Additional TeX packages can be imported when a project needs them, making it easier to keep working even without a remote build environment. Key Features • Clean LaTeX editing environment • Local compilation for supported documents • Fast switching between source and PDF preview • Auto-completion for brackets and commands • Document creation from templates • Editing for local and cloud-based files • Background compilation with completion notifications • Build logs designed to make errors easier to understand Whether you are studying, researching, drafting a paper, or polishing a technical document, TeX Go gives you a practical LaTeX workspace on iOS.

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.
