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.

The Bagpipe Tuner App allows precision tuning of Highland bagpipes. Simply sound a note and start tuning. It's easy and accurate. Bagpipe Tuner App for Highland Bagpipes accurately detects your pipe chanter notes, drones and displays the note, frequency and pitch position. Detection is via the inbuilt microphone, or in noisy environments an external microphone like the HBT clip mic can be attached. Bagpipe Tuner features both digital and analog style meters, waveform input monitor and auto gain limiter. Simply press the Learn button and start tuning, or turn horizontal to access a larger meter display. Using a Bagpipe Tuner can really make tuning less stressful, listening more pleasant and playing more enjoyable. You can quickly check your pipes at anytime to maintain good tone– before a gig, practising or competition. And, non-pipers can easily use it to help out with tuning. Why a Bagpipe Tuner? Highland bagpipes are incredibly hard to tune and unlike standard chromatic instruments, the intervals between each note continue to vary. Bagpipe Tuner correctly displays the scale and takes the guesswork out of using a chromatic tuner. Bagpipe Tuner compliments the standalone BLAIR tuners and Bluetooth clip. Features: • Auto detection and display of notes and drones • Analog style meter • Large horizontal display • Frequency display meter • Input waveform meter • Frequency position bar • Learn function for calibration setting • Auto input limiter • Internal microphone • External microphone support (HBT clip mic) • Large frequency detection range • Special Bluetooth mic/ sensor for Bagpipes supported

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.
