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.

Taptanium™ certified nature audio comes from the most pristine sources such as Hawaii and has been mastered to perfection with the highest attainable level of attention to detail, spending many of hours of analysis for every minute of audio while utilizing artificial intelligence to detect even the most distant human-made noise intrusions that humans are nearly incapable of recognizing under normal circumstances. Only the purest and highest quality nature sounds in the world can attain this certification. Experience Taptanium™ neural 3D audio™. If you put on headphones, Sunny creates an incredible sense of immersion. The nature and water plays all around you, not just on your ears.

Mix and match multiple sounds to your liking by adding some extra rain on a tent or sea birds around you. Get the great sleep and productivity you deserve.

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.
