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

If you coach lacrosse, you’ve probably been there… Can't find the whiteboard during a timeout. Lose track of score in competitive drills. Practice plan is in your head (or on a crumpled sheet somewhere). I built DrillScore to help me with those things, and I figured it might help you too. Everything you need to run practice, right on your phone: Scoreboard Keep drills competitive and organized with a clean, simple scoreboard. • Custom team names and colors • Quick + / – scoring • “First to” game modes Coach Board Draw drills on the fly, no more scrambling for a whiteboard. • Smooth drawing tools • Full and half-field views • Player dots • Easy reset and redraw Practice Planner Actually stay on schedule. • Build out your full practice • Track total time and drill time • Keep everything in one place Built-in Timers Run drills without guessing. • Simple, easy-to-use timers • Keep practice moving • Stay organized under pressure Built by a coach I’ve coached for 20+ years and made this tool for help with my own practices. No fluff. No unnecessary features. Just what you actually need when you’re on the field. Who it’s for • Youth coaches • High school coaches • College coaches If you run practices, this is for you. If you’ve ever said, “Hold on...what’s the score?” or “Where’s the whiteboard?” You’ll use this every day.

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.
