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.

Turn clean sounds into something more alive. Wind Crusher is an AUv3 effect for adding air, fizz, bite and digital movement to pads and fragile vocals in particular, but also electric guitars and snares can benefit. It starts where many bitcrushers stop. Instead of immediately destroying your sound with extreme lo-fi distortion, Wind Crusher lets you explore the subtle texture created by quantisation — adding digital residue while keeping the original character intact. Use the large AIR control to mix in and out the sound appropriately, then fine-tune the result with: • Bit Depth for controlling the digital resolution • Swoosh for adding movement and texture • Texture Tone for shaping the character • Air EQ for opening up the high frequencies • Mix for blending the effect with the original Use it subtly to add breath and presence. Push it harder for brittle edges, fizz, aggressive breakup and obvious digital destruction. Wind Crusher is designed to be quick to use, but deep enough to experiment with. A small set of presets helps you explore different characters without needing to understand every DSP parameter. Some of the effects in Wind Crusher rely on sounds within the 350-2000 Hz range and so you may get more audible results if your input sound contains frequencies in that range. Made for musicians, producers and sound designers who want to add a little extra to their clean sounds. Wind Crusher is built as an AUv3 Audio Unit for use with compatible music apps and hosts on Apple platforms.

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.
