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.

Purple Onion is a free browser that empowers you to use the internet more securely. Purple Onion uses Tor to encrypt your Internet traffic and then hides it by bouncing through a series of computers around the world. Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis. Purple Onion is the only app that creates a truly private internet connection. ACCEPT NO SUBSTITUTES: Purple Onion is the safest way to use the Internet - Period. Purple Onion bounces your encrypted traffic several times through computers around the world, instead of connecting you directly like VPNs and proxies. This process takes a little longer, but the strongest privacy and identity protection available is worth the wait. PRIVATE WEB SURFING: Purple Onion is the most anonymous way to access any website, even if it’s normally blocked, monitored, or on the hidden web. PRIVACY FOR EVERYONE: Tor can help you confidentially research a competitor, get around someone blocking your favorite site, or circumvent a firewall to watch sports at work. ***We Love Feedback*** MESSAGE US: Are we missing your favorite feature? Found an annoying bug? We’d love to hear from you! Send us an email. [email protected] Important Notes: - Web browsing/downloading through the anonymization network will be SIGNIFICANTLY SLOWER than through a non-tunneled browser like Safari. This is necessary and a small price to pay to keep your identity protected. - This product uses the Tor distributed networks is produced independently from the Tor(r) anonymity software and carries no guarantee from The Tor Project about quality, suitability or anything else.

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.
