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.

Rep Jam Gig is the working notebook for musicians — singers and instrumentalists — who gig and jam. Your repertoire in the keys you do it in, every jam and gig logged, set lists that build themselves, a calendar of what's coming, and a directory of everyone you've played with. It's one app, not five. Log a jam and the songs you called file themselves into your repertoire; the players you name build themselves into a directory. What you do on a Tuesday night makes the app more useful by Friday. WHAT IT TRACKS • Repertoire — every song you know, sorted Performance Ready / In Progress / Want to Learn, with your key, the credits and any notes you need at the stand; searchable and filterable by genre • Jams — log who you played with and what you played, grouped by night • Gigs & Set Lists — build set lists from your ready repertoire, with a tempo-aware builder, and save what you actually played • Calendar — plan the jam sessions you mean to go to, with repeats like "every Wednesday" or "the third Monday of the month". Star the ones you care about, search by name or place, and log a session as a jam in one tap. Import any calendar's .ics file; your own exports back out the same way • Musicians — a running directory of everyone you've played with, built automatically from your jam and gig entries, with instruments and Instagram handles Songs you perform that aren't already in your repertoire file themselves under In Progress — with composer, lyricist and year filled in from the built-in songbook of 2,500+ standards — so nothing falls through the cracks. BULK IMPORT AND EXPORT Already have your setlist in a spreadsheet? Download one CSV template covering your whole library — repertoire, musicians, jams and gigs — fill it in with Excel, Numbers, or Google Sheets, and import it back in. New entries are added; songs and musicians already on file are matched by name and merged, never duplicated or overwritten with blanks, so re-importing the same file is always safe. Export All Data writes everything back out as a single CSV, for a backup or for moving to a new device without iCloud. SYNC ACROSS DEVICES Turn on iCloud sync and your repertoire follows you from iPhone to iPad automatically, using your own iCloud account. Nothing is sent anywhere else. DESIGN A dark, uncluttered interface with serif type throughout — built to be read quickly at a stand or a bar, not to look like a spreadsheet. Rep Jam Gig starts empty. There's no sample data to delete and nothing to configure — just start adding what you actually play.

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.
