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

Track Crafts Inventory and Projects Custom-designed with the help of experienced crafters, Krafts is smart about helping you organize your materials and projects. You can add and edit categories to suit your needs. The built-in UPC scanner uses your device’s camera to scan barcodes and automatically fetch product images (if available online). While shopping, you can scan barcodes in the store to easily check if you have those items in your inventory. You can also “flag” items that have special significance (e.g., need restocking). Krafts is not affiliated with any supplier or retailer, so the app never tries to sell you stuff. The data in the app are YOUR data — no ads, promos, or company videos. Krafts is more complicated than similar inventory apps, but that’s because it’s flexible and does so much more. Please read the extensive Help section in the app (and online at: http://mat.buddy.com/krafts). Features: • Maintain inventory of supplies and tools. • Enter new project ideas and track projects through to completion. Add more details along the way. • Designed for any craft. • Create your own categories (e.g., “Card Stock,” “Tools,” “Books”). • Add customized fields to each category (e.g., “Name,” “Quantity,” “Company,” “Photo”). • Keeps photos of your items and completed projects. • Scan UPC barcodes using the camera (only some codes have online data, see below). • Scan store items while shopping to check for matches in your inventory. • Add item photos using the camera or barcode scan. • Help page assists with learning the app. • Tutorial mode: help and tips for every screen. • In-app Backup/Restore to/from your desktop PC. • Email or print your entire database for safekeeping. The scanner uses a public database to convert UPC codes to text. The database does not include all barcodes, and new ones are being added daily. However, even if a barcode is not in the database, Krafts will still save the number to allow match-ups when scanning the same barcode in your stash or a store. Please contact me directly with questions or suggestions (hint: use the "Email Jeff..." button on all Help pages). Please do not put questions and suggestions in a review because I'll have no way to contact you.

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.
