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

Sun out. Top down. No regrets. Stop overthinking the clouds. Top Off? is the ultimate decision-maker for Jeep owners, Bronco drivers, and convertible enthusiasts. When you want to drop the top but the forecast looks "maybe," we give you a definitive answer in one tap. The Problem Standard weather apps give you percentages, wind speeds, and radar maps. You have to be a meteorologist just to figure out if your seats are going to get soaked at a stoplight. The Solution: One Tap. Total Freedom. Top Off? strips away the noise. We grab your hyper-local coordinates, run the current and upcoming conditions through our proprietary comfort algorithm, and tell you exactly what you need to know: Top Off or Top On. Why use Top Off? Zero-Effort UI: No menus, no search bars, no clutter. One button. One answer. Hyper-Local Accuracy: We check the weather where your tires are touching the pavement, not just the general city forecast. Built for the Open-Air Life: Our algorithm factors in more than just rain. We look at temperature, wind chill, and sky conditions to ensure you’re actually comfortable, not just dry. Decide in Seconds: Perfect for when you’re walking out to the driveway or sitting at a long red light. Protect Your Interior Don't risk your leather seats or electronics on a "30% chance of rain." Use the app designed for people who live for the wind in their face but hate the water in their floorboards. Stop guessing. Start driving.

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.
