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.

MotifPilot helps producers get past the blank DAW session with editable MIDI starters built from clear musical controls. Choose a genre, mood, key, scale, tempo, bar count, complexity, humanize, and swing. MotifPilot's local, rule-driven engine builds a theory-aware four-track sketch starter with chords, bass, arp, and melody so you can preview the idea, shape the arrangement, try another variation, and export usable Standard MIDI files for your DAW or file-sharing workflow. Built for electronic music producers, songwriter-producers, and mobile producers: - Generate 4, 8, or 16 bar MIDI sketch starters from clear musical controls. - Work in 12 keys across all pitch classes. - Start from pop, trap, house, R&B, cinematic, techno, trance, hardstyle, UK garage, drill, D&B, lofi, and hip-hop directions. - Use Next idea to create another sketch from the same setup. - Enter your own chord progression, replace selected chords, or explore chord and progression suggestions. - Preview the result with built-in playback. - Focus tracks with mute and solo controls. - Push variations such as simpler, darker, jazzier, more emotional, more sparse, more rhythmic, tension, and resolve. - Edit focused tracks with octave, transpose, quantize, velocity, duration, note movement, add, and delete controls. - Undo and redo edits while exploring. - Export a full starter MIDI file, individual-track MIDI files, a plain-text DAW import guide, and a ZIP package through the iOS share sheet. - Keep recent projects and export records saved in the local Library on this device. - Open saved projects in Studio, export projects again, rename, tag, search, share, batch-manage, and delete local items. - Detect missing export files and rebuild the package when the remaining local files or linked project can support it. MotifPilot is not a full DAW, audio generator, one-click song maker, giant MIDI pack browser, direct DAW integration service, or AI prompt-to-MIDI service. It is a local-first MIDI sketching tool for creating editable musical starting points that you can import into your DAW.

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.
