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.

"Marble Math is one of the most fun, customizable, and effective math games available for older elementary school-age kids." - Common Sense Media "It requires both game skill to be able to roll the marble and math skill to understand and come up with the solution of where to roll it." - Wired ________________________________ FUN MATH PRACTICE: Based on the Common Core Curriculum, Marble Math is an engaging way for upper elementary students to practice mental math. Earn new marbles and collect bonuses while reinforcing key concepts in pursuit of a high score. But watch out math whizzes! You’ll need to be focused and nimble to avoid the obstacles in your path. WRONG ANSWER? NO PROBLEM: Marble Math gives you the option to replay the question or show the correct answer, before moving on to the next problem. UNLIMITED USER ACCOUNTS: Add as many custom profiles as you like. Individual game settings and progress are saved in each player profile. Create different profiles, each tailored for specific practice and abilities. CUSTOMIZE FOR SPECIFIC CONCEPTS AND ABILITY: Parents and teachers can customize gameplay to concentrate on specific math concepts by selecting problem types for each player and level. MARBLE MATH CONCEPTS INCLUDE: • addition, subtraction, multiplication and division • adding and sequencing fractions with different denominators • factoring • sequencing decimals • adding and subtracting negative integers • counting money (USD, AUD, CAD, EUR or GBP) • comparing number values • simplifying equations • sequencing roman numerals And more...

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.
