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.

Aries Rotary is a powerful, all-in-one rotary speaker and amplifier simulator designed for guitar, organ, synths, vocals, and more. Crafted using the latest modeling technology, Aries makes it easy to achieve the famously lush, warbling tones that rotary cabinets are known for. It can be used as a potent AUv3 effects plugin or as a plug-and-play standalone app. It is compatible with the iPad, iPhone as well as Apple Silicon computers. The rotary module offers six distinctive cabinet types. It comes with an extensive set of parameters that helps you tweak and control the sound in fine detail. The horn and drum each have their own dual microphones. Each mic has dedicated gain and pan. Each pair of mics also have continuously variable distance and angularity settings that alter the characteristics of the modulation effect as well as its stereo footprint. The individual fast / slow mode speed settings, as well as acceleration / deceleration parameters allow you to change the interaction between the horn and the drum, or to recreate various popular cabinet “mods.” The independent amp module presents six unique virtual-tube amplifiers to choose from. The amps can be mixed and matched with the cabinets as desired, or can be completely bypassed. The amps are specially designed to work with a wide variety of instruments, and feature an extensive set of tonal controls. While offering extensive headspace with sparkling clean tones, each amp is also capable of being pushed into warm overdrive with the characteristic definition of tube saturation. Each amp is also equipped with a built-in spring reverb module that helps conjure analog reverb tones of classic amps. A carefully tuned “Post FX” module helps you further hone the big tones generated by the Aries audio engine. These effects include a 3-band “Baxandall” inspired EQ stage, a room emulator to add extra dimension and resonance, as well as a vintage-inspired compressor for adding sparkle and attack to the sound. Professional features include a powerful preset management system that allows you to create, modify, and share banks and presets; MIDI learn complete with augmented settings at the parameter level; fluid layout that accommodates wide variety of screen and window sizes; 50+ factory presets that appeal to a variety of musical styles, and more. The standalone app also includes a built-in "tape deck" where you can record, play and share your creations. Aries Rotary is the inaugural offering in Yonac’s Zodiak series of next generation plugins. The Zodiak series aspires to provide sophisticated and powerful effects built on cutting edge audio processing technology for working musicians and the enthusiasts alike.

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.
