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.

Here’s what you can do on Threads: ■ Start a thread, share your take Have something on your mind? Take it to Threads. Share a thought, ask a question or open up a conversation. There’s more than one way to kick things off with text, images, polls, ghost posts and more. ■ Jump into replies Jump into the discussion, react to new ideas or just see where the conversation goes. Every thread is an invitation to join in. ■ Keep up with what’s trending From live scores to breaking moments, Threads helps you stay close to what’s happening —and join the conversation when you’ve got something to say. ■ Control the content you see Control who can reply to you, mention you or see your posts. Use Hidden Words to filter out posts and replies that include words or phrases you don’t want to see—so your experience stays on your terms. ■ Go deep on your interests Follow friends, creators and communities for every interest. Threads is built to help you discover new voices and join conversations—starting with the communities you care about most. ■ Connect over chat Keep the conversation going privately with 1:1 and group DMs. When a public thread gets more personal, move it to your inbox to go deeper or share it with a smaller group.

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.
