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 OFFICIAL ABRSM Aural Trainer contains interactive challenges to help develop your music aural skills (listening skills). Anyone can use it, but it is designed around ABRSM’s aural tests for Grades 6 to 8. The app can be used in any order, however often you like, on your own or with your teacher. Use ABRSM Aural Trainer to: • Exercise your musical memory (remember how music sounds and be able to repeat it). • Develop your confidence and accuracy at sight-singing (reading and singing the music you see). • Improve your recognition of cadences, chords and modulations. • Learn to describe texture, structure, dynamics, articulation, tempo and tonality. • Practise identifying the features in music that make-up its style and character. • Develop the skills to know when a piece of music was written. The app covers the following ABRSM aural test content: • Melodic Repetition • Sight-singing • Cadences • Chords • Modulations • Musical Features • Rhythmic Repetition • Metre All exercises are fully interactive. Each one gives you the opportunity to repeat the question, or to compare your response to the correct answer and hear the music again . The app also features supporting tools including a cadence trainer, progress tracker and guides to the aural tests in ABRSM graded music exams. Many exercises are automatically marked by the application. Self-review and critical listening are also key to successful development of the musical ear, which is why the app provides tools for you to review and evaluate your performance against sample responses in all cases. Your progress is logged whenever you use the app, so you can always see at a glance the areas you might want to revisit.

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.
