- Keep an editable draft if export fails.
Okay so there used to be this app that taught me so much about color theory and it's been gone for years and I've honestly been thinking about it ever since.

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.

Okay so there used to be this app that taught me so much about color theory and it's been gone for years and I've honestly been thinking about it ever since. Here's the thing about color: there are actual reasons for why certain combinations feel so good together, and once you learn them you start seeing them everywhere. In your closet, in interiors, in art, in the fits you stop to look at on the street. Nuanua is basically a color wheel that shows you those relationships in real time. Pick any color and it'll show you what plays well with it, complementary, analogous, triadic, all of it, but without the design school jargon getting in the way. My favorite feature is the photo upload. You can take a picture of anything, a jacket, a paint swatch, a couch you're trying to match, and pull colors straight from it. Then you can build a palette around it and save it for later. I made this mostly because I wanted to get better at putting colors together when I get dressed, and I figured other people probably felt the same way. You don't have to be a designer to have an eye. Sometimes you just need a little help developing one.

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.
