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.

EXPERT INSTRUCTION While other trainers throw around the term boot camp to describe their programs, Lori Patterson actually trained soldiers while serving in the U.S. Army. Lori is also an ACE, ASCM, AFAA, and WellCoach certified personal trainer. Boot Camp Challenge programs combine authentic military conditioning with the principles of safety and science from the fitness industry, ensuring you a safe and effective workout. Lori will be with you every step of the way, giving you the tips you need to get the most out of your workout and the motivation to keep going no matter how tough it gets. A COMPLETE WORKOUT The Boot Camp Challenge Program combines cardio, stretching, and muscular endurance training in each workout to help you lose fat, improve strength and endurance, and enhance your functional fitness. Basically, you will be building a better you, and with this circuit-style workout, you will do it faster than you could imagine. BEAT-SYNC Boot Camp Challenge dynamically changes the beat of YOUR music to perfectly match your movements. Research shows that music distracts the brain during exercise and faster music causes people to accept and even prefer a greater degree of effort. This means you will work harder without trying (or without even feeling the difference), you will get better results from the increased effort, and most importantly, the time will fly by. DESIGNED AROUND YOU Lori Patterson has worked with thousands of people and she knows how to safely and effectively guide anyone towards their goal. Whether you're a first time exerciser or an extreme fitness enthusiast looking for a challenge, BCC has the right program for you. Plus Boot Camp Challenge gives you control of your program. Change the exercises to match your equipment or simply pick your favorites. You can even turn the intensity down a bit when you're struggling or crank it up when you're ready for more, and Boot Camp Challenge adjusts your workout — and your music — on the fly.

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.
