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.

This is the second of a series of six sonic meditation recordings by Glenn Harrold and Ali Calderwood, which are based upon the ancient Solfeggio musical scale. Each note in this scale has specific healing properties and this recording uses the second note, which resonates to a frequency of 417 Hz and is associated with the colour orange and the element of water. This particular frequency works to dissolve emotional patterns and imprints from the past and facilitate positive changes. It will also help to clear other emotional patterns, such as low self-esteem, self-rejection, overindulgence, jealousy and emotional instability, all of which exist within the same vibrational energy. It has been said that the solfeggio tones can even help to release blocks and traumas from past lives. Glenn Harrold's skilled vocal delivery and guided meditation combined with Ali Calderwood's deep and moving soundscapes tuned to 417 Hz combine to create an amazingly powerful meditation recording that has the potential to clear away blocks on a deep cellular level. Listen now to resolve past traumas and facilitate changes that will leave you feeling lighter and free of old baggage. There are two audio tracks in this App, the first has a wake up ending for daytime use, and the second has a go to sleep ending which is ideal for bedtime use. This App includes: 417 Hz Solfeggio Sonic Meditation Audio Track 1 – 37.11 (awake version) 417 Hz Solfeggio Sonic Meditation Audio Track 2 – 42.11 (sleep version) RE 417 Hz Solfeggio Music Only Audio Track – 10.18 Solfeggio Chakra Chart Glenn Harrold's Self-Hypnosis e-Book. About the Ancient Solfeggio Scale and Healing Sounds e-Book How To Use This App e-Book About The Authors e-Book About the Sounds The music with this series of mediations has been specially crafted and precisely tuned to transmit each of the solfeggio frequencies. By combining these sounds with a guided meditation, you also have the potential to release deep-rooted blockages. These compositions also contain an array of sacred instruments and sounds such as crystal bowls and didgeridoo and sacred chants, which work to further enhance the effects of the Solfeggio tones.

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.
