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.

Warm Me Up! is the most comprehensive and varied vocal warm up tool available to today's singer. Tailored to your voice type, there are 60 exercises designed to guide you through a warm up that will get your voice into tip-top condition and ready for your practice session, rehearsal or performance. Warm Me Up! will create a unique warm up for you. It can generate a warm up based on how much time you have available or you can browse the individual tracks and create your own playlist. The exercises are recorded in high quality audio: a lush baby grand accompanies you through each exercise and a professional singer guides you through the first two repeats of each. The Warm Me Up! team (Luke Hunter, Vicky Jacobs and David Young) are esteemed voice coaches and musical directors and have warmed up professional singers in Australia, the USA, New Zealand and England. Between them they have warmed up the casts of many mega musicals including Jersey Boys, Wicked, The Book of Mormon, Frozen, Come From Away and Moulin Rouge. Warm Me Up! is specifically designed to be used by both the amateur and professional singer and can be used to warm up a soloist or larger group. It's a fantastic resource for singing teachers and choir directors who can warm up their ensemble away from the keyboard. In the studio, backstage at the concert, in the corridors or in the car on the way to the audition, now you can warm up professionally... anywhere.

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.
