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.

coaching made easy. a portable pacing system that teaches athletes to train and race at a proper pace. coaches can refine their training without sacrificing their workout time goals. what coaches have to say "i have used a pacing system for all my workouts to challenge me on my tough interval days. it keeps my workouts honest. always has. my workouts would not be the same without it." -- m. boyd "a pacing system has been the backbone of my training for the last 40 years. olympic medalists, college champions, all-americans, and countless others have benefited from more accurate, efficient, and consistent workouts. this one works better at a fraction of the price." -- coach clyde hart "having been introduced to the concept of the 'beeper system' as a ga at baylor 40 years ago, when it was first discussed, i became enamored with the idea and have used a whistle and a pace chart in my training since then to simulate the beeper . the new 'pace beeper' app would now allow me to focus my attention on my athletes rather than the chart and stopwatch while they are training. it would also allow me to reach out to more athletes during practice as more than 1 runner or group could be running at one time. " "great idea!!" -- coach jack sands main features [+] create fine-tuned timer intervals [+] run multiple timers simultaneously [+] edit timers [+] auto-calculate interval times [+] import custom beeper sounds (via your itunes music library) –––––––––––––––––––––––––––––––––––––––––––––––––––– more details * pacebeeper allows you to train multiple groups using a time tested method that optimizes your workouts for all levels of performance. increased workout efficiency, accountability, more accurate training means better results. * coach hart puts great emphasis on training at the proper pace and volume-- fine-tuning a workout is not enough if execution lacks accuracy. * giving athletes immediate feedback to their prescribed pace allows them to train smarter. –––––––––––––––––––––––––––––––––––––––––––––––––––– workout benefits [+] more streamlined [+] consistency is honed [+] injury risk is reduced [+] focus and ability are increased "i can't imagine trying to fine tune workouts without giving my athletes a target. pacebeeper gives them time during each interval to make corrections as they go. i can also train the whole team simultaneously." -- coach clyde hart

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.
