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.

I will let everyone know to try this app and re-evaluate their position on digital blueprints.”  "Finally! This is the viewer that handles any size image I throw at it. Even ones with many dozens of megapixels! I have been looking for something like this. Others I have tried are extremely slow at scrolling or zooming, or can't handle the large images I want to view. But LargeViewer is screaming fast and can handle ever size image I have tried." "LargeViewer is the best large image viewer I have seen, by far. And now with the new iPad with retina display it's even more useful! Simply stunning! If you want to view pretty much any resolution image and really show off what the retina display can do, you've got to get this app! Butter smooth scrolling, and just refuses to crash even when throwing 80-megapixel Phase One IQ180 images at it!” "I am a professional civil engineer. I now have all my drawings loaded to my iPad when I go for inspections. It works well for large files and it is FAST." "Incredible. Test passed with a TIFF file from 11.000 x 5700, weight 190 MB. Fantastic. It has a button to zoom to 100%, and it’s easy to go beyond the resolution of the file. Thanks and congratulations for the work. App absolutely recommended.” ► To get answers to your questions and make suggestions for future improvements, tap LargeViewer's Email Support button.

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.
