A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
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.

To celebrate International Joke Day 2022, we wanted to make an audio plugin. This plugin had to be a bit different. We started by creating a dustbin sound system (garbage can for our American friends). We got a real dustbin and put some speakers in it! After it all was done, we ended up with an interesting creative audio effect plugin called Dustbin! This plugin will litter-ally change your life. Stop wasting time, you can’t refuse it any longer. Take everything you thought you knew about music production and throw it out. Imagine you left two easily entertained idiots alone with a dustbin, amp, speaker, some microphones, and a worrying idea. Well actually, you don’t have to imagine at all, because Dustbin is here to answer those musical questions you never asked. Pick your way through the impulse responses taken from the Bin’s cavity and built-in speaker. Transform your Garage into Garbage, Rap into Scrap, Pop into Slop, Punk into Junk, and New Age into Sewage. No more worrying about IF your music sounds trash, now it definitely does. You’re welcome. Dustbin is both a stand-alone application as well as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as GarageBand.

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.
