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 one of a series of 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 resonates to a frequency of 852 Hz and is associated with the colour of indigo and the element of light. Glenn Harrold's acclaimed vocal delivery and guided meditation combined with Ali Calderwood's deep and moving soundscapes tuned to 852 Hz combine to create an amazingly powerful meditation recording. The combination of these special sound frequencies and a guided meditation will help you to release deep-rooted blockages and negative patterns of behaviour. This frequency will help you to awaken your intuition and connect with your inner light. It can also help with every day problems like headaches, lack of concentration, bad dreams, and nervousness, as all of these issues exist within the same vibrational energy. This App contains two inspiring guided meditation tracks plus an 852 Hz frequency music track. The first meditation track can be used in the daytime, as it will guide you back to full waking consciousness at the end. The second meditation track will guide you into a deep sleep state at the end, which makes it ideal for using before you go to sleep at night. The music includes 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. When you are instructed to repeat affirmations on the meditation tracks, connect with positive feelings (e.g. happiness, joy, love), as this will help you absorb the suggestions on a deeper level. You don’t have to repeat the affirmations out loud but do make a strong connection with them.

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.
