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.

simple dulcimer tuner to tune up your dulcimer. this is for the standard daa dulcimer ionian tuning. tuning your dulcimer can be a difficult task for you if you are just beginning dulcimer. the good news is, the more you do it, the easier it becomes. a nicely tuned dulcimer can make your music sound a lot better and help you greatly while you're are just getting the hang of finger placement for notes. touch the note for the string you want to tune and then turn the tuning pegs on your dulcimer and match it up with the note that is being played. tip: make several passes tuning each of the strings. for example you might have noticed that if you have tuned all the strings once, and then back to the first one you tuned, it might be off a little bit. this is because you are increasing or decreasing the tension on each of the strings as you tune it and the instrument's body might bend ever so slightly due to this difference in tension. this causes the other strings to slightly change in pitch. so make sure you keep on checking and tuning the strings until all are in tune, so make several passes. any questions using the app? write [email protected] and we we'll get back to you promptly. or visit our forum at www.tuneinstrument.com . if you need to tune other instruments just simply have a look into our other applications: cello tuner simple, violin tuner simple, banjo tuner simple, mandolin tuner simple, double bass tuner simple, 12-string guitar tuner simple, viola tuner simple, guitar tuner simple, ukulele tuner simple, bass tuner simple, dobro tuner simple, balalaika tuner simple. or visit us at: www.tuneinstrument.com .

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.
