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

The U.S. Army designed Hand-to-Hand Combat (combatives) training to ensure every soldier is tough and adaptive to changing conditions, more confident in their abilities, and equipped with the tools necessary to dominate their environment. Since our original version of the app, the Army has redesigned their program to focus on a more mixed martial arts approach called the Modern Army Combatives Program (MACP). The older manual (Field Manual 21-150), which grew out of experiences in WWII, is still included, but the focus is on the new MACP program. MACP stands apart from the vast majority of martial arts training in that producing actual fighting ability is of primary concern. The mental and physical benefits of training gain their worth from their usefulness in producing more capable soldiers. It bridges the gap between physical training and tactics. The products of a good physical training plan, strength, endurance and flexibility are directed toward the improving the fighting ability. The three phases of basic fight strategy are: - Close the distance - Gain dominant position - Finish the fight To accomplish this MACP took the concept of positional dominance from Jiu-Jitsu, expanded it to the other ranges of combat and blended in techniques from wrestling, boxing, Muay Thai, judo to name just a few. In addition weapons fighting lessons were added from Kali, the western martial arts and the Army Rangers’ own experience from years in the infantry. Hand-to-Hand Combat also includes video clips to help reinforce the material and fitness calculators to help with your training. If you are interested in hand-to-hand combat and military training, this app is one you won’t want to miss.

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.
