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

NOTE: LEGO® is a trademark of the LEGO Group of companies which does not sponsor, authorize or endorse this App. The Unofficial LEGO Minifigure Catalog App is a must for every LEGO enthusiast! The app contains information about all of the minifigures and sets from 1975 through 2015, including all Collectible Minifigures and non-standard scale figures such as Duplo, Fabuland and Belville. This is over 7,900 minifigures, 1,600 heads and 5,400 sets! Each year, we spend several hundred hours photographing, cataloging and updating the app with all of the newest minifigures released. Professional high-resolution photographs of every minifigure and the associated data are included. Click on the thumbnail to get a full screen picture that you can zoom into. Browse the minifigures and sets by name, theme or year. The Unofficial LEGO Minifigure Catalog App can even import/export your data to Brickset.com. Note: We are in the process of trying to acquire all 2016 and 2017 minifigures to photograph. If you or someone you know has a collection, please let us know: [email protected] Features === * More than 7,900 minifigures, 5,400 sets and 1,600 heads listed * Collectible Series 1-16, Team GB, The LEGO Movie, The Simpsons 1 & 2, Disney and more * High-resolution photographs of every minifigure and head * Browse by name, theme or year * Search by name * Manage favorite minifigures * Mark the minifigures you own * Import and export with Brickset.com * Images are downloaded and cached to your device only once needed * Regular free maintenance updates System Requirements and Limitations === * The App runs on all iOS devices, including iPad, iPhone and iPod Touch. iOS version 7.1 is required. * The application uses your internet connection to download the images the first time you look at them. We recommend using a Wi-Fi connection to avoid possible charges from your network provider. Once loaded, the images are cached on your device and no further internet connection is required. * A Brickset.com account is necessary to import and export data to it. Please notice that neither Brickset.com nor our App is able to resolve version conflicts. If you edit the same figure on both the App and the website, then one of them will be lost. It is also possible that Brickset.com has minifigures that are not yet in our App and vice versa. Support === Please let us know if you experience any problems with the App. You can leave a comment at http://www.minifigure.org or send us an email at [email protected].

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.
