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.

with audio sauce you can easily add audio effect “flavor” to your videos and save them or share them to social media quickly, while the inspiration is still fresh. audio sauce is designed with a simple, artist-friendly interface that encourages the user to feel like they are at play – but there is plenty of functionality underneath the hood. with its suite of essential effects you can create results that run the gamut from tasteful polish to wildly experimental. - load any video from your device’s media library or record a new video. then: - boost the volume of your video with an output limiter - add delay by tapping for tempo then choosing the rhythmic pattern you want, including regular, triplet and dotted half, quarter and eighth note divisions - add reverb by choosing from one of four styles ranging in size from medium room to cathedral - add “dirt” by choosing one of two modes, “mild” or “hot”, for anything from subtle tape saturation to fully obliterated distortion - use the eq module’s bandpass filter to roll off unwanted high or low frequencies or boost/subtract with an eq shelf - play with the pitch shifter and blend in any interval (including octaves, fourths and major and minor seconds, thirds, fifths, sixths and sevenths) when you’re happy with how your video sounds, save it to your device or share it directly to social media. the ability to save and share your video can be unlocked with a one-time purchase.

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.
