Generating… usually about a minute.
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.

My five-year-old tried reading a book on her own… and amazingly, the system picked up her little voice and played the effects at all the right moments.” - Michelle Woo, Lifehacker "Not only did this tool help make poetry come alive for [my student], he asked me if he could try reading... I about fell out of my chair because he never wants to read aloud... and he has asked to go to the library to check out books that he can read along with the app." - Julie Smith, The Techie Teacher® "I think this is cool as cool can be… I love it, I love it!" - Lori Greiner, entrepreneur and investor on ABC’s Shark Tank SAFETY, PRIVACY, AND SUPPORT - Novel Effect requires access to the device's microphone to perform voice-recognition. - The privacy of kids and their grown-ups is our top priority.

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.
