Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

ChromaMagic - the magical color tool for artists - now with LIVE camera views. Have you ever been painting and said 'but what *is* that color?' Me too! ChromaMagic exists for one reason only. My paintings looked wrong. I just couldn't get the colors in my paintings to look convincing. Try as I might there was always something off. Too bright, too light, too gray, not gray enough. Too blue, too brown, too pink. Why oh why could I not make things work? Well it turned out it wasn't in the paint. It wasn't in the mixing. Special brushes didn't do the trick. Making those daft color charts didn't help either. And it wasn't even in the way I put the paint on the paper. The problem was in my brain. The problem was that I had no chance of mixing the right color. I was missing an essential part of the painting process. Something that would take years if not decades to figure out. And the reason was that I wasn't *seeing* the right color. Now I don't mean there was something wrong with my eyesight. What I mean that I was 'seeing' color but I wasn't really seeing *COLOR*. I didn't have the words or the means to really understand what I was looking at. And if we don't really know what we're looking at how on earth can we translate it into paint? Even if we don't want to represent what we see how do we know what to change to enhance the effect? Flip a coin? Trust chance and experimentation? Repeat for years and years until we stumble on something that works....? No. So what changed? Everything changed. I learned to forget about primaries, secondaries and tertiaries. I learned to ditch the traditional artists wheel. I learned to stop talking about 'warm' and 'cool'. I learned to see color the way it is and not the way I expect it to be. I had to forget everything I had been told. I learned about hue, value, and chroma. Munsell. With ChromaMagic you can load up any photo or reference and see at a glance what any color is. And the colors are described in a way that is most natural for artists. What is the hue (red, yellow, green etc)? Yes! And what is the value (very important)? Yes! And what is the chroma (how gray or saturated it is)? Yes!!! Color makes so much more sense now. But there's more! As well as the Munsell color mode (which is fabulous by itself!) there are 4 extra modes to help you really see what is before us. - Want to organize your reference into the major value shapes? Value mode will do that and you can change the number of value steps with a click of the mouse. - Want to reduce your reference to just grayscale to really see those fine-grained values? Yes! - Want to see how saturated or gray your colors are (this is always surprising!). Yes! - Want to see how your colors are distributed around the color wheel? Yes And yet there's still more: - No more clicking around - ChromaMagic has a fantastic new interface with buttery smooth zoomable, pannable images. - No more need to be tethered to wifi. Take ChromaMagic anywhere - even up a mountain! - Too many colors in your reference? Average your colors over multiple pixels - 2500 of them if you want to. - Want to know which paints are available for a certain color? ChromaMagic now has links to hundreds of top quality oil paints. - Want to use ChromaMagic at home? On the bus? On a tablet? Now you can run it on your iphone, ipad or mac. All for one price! - No more silly loading buttons. Drag and drop your files in one swish on the desktop (Bliss!!) - Use ChromaMagic next to the easel for mixing. Now with mixing swatches and calibration values (no need for $1500 Munsell chips)

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
