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

Catalog your entire home library in an afternoon. Snap a photo of any shelf and the AI adds every title. No typing, no spreadsheets, no scattered notes. Trusted by 600+ readers and rated 4.1 stars on the App Store since 2011. • Catalog a 200-book shelf in five minutes. Point your camera. AI reads the spines and adds the books. • Add a single book in seconds by scanning the barcode on the back cover. • Bring your Kindle library across in one tap. No CSV juggling. • Find anything in plain English. "That biography about the architect" works. • AI sorts your shelves by genre, mood, and theme so you stop tagging by hand. • Read on iPhone, edit on iPad, look something up offline at the bookstore. Sync handles the rest. How it works: 1. Point your camera at a shelf and let AI populate your library. 2. Sort, tag, and mark books as Read, Reading, or To Read. 3. Pick up on any device. Share with friends, join a club, ask for a recommendation when you want one. Coming from another app or a spreadsheet? Import CSV, TSV, JSON, XLSX, BibTeX, or RIS files. Field mapping is built in. Real review: "I had a bunch of books I needed to inventory and the barcode scanner made it incredibly easy. Great app." BuckeyeCityCates, App Store review, 2024 Free to start with twenty books and three barcode scans. Open the app and add your first shelf.

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.
