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

Experience NYC's Central Park in all it's beautiful entirety. Perfect for locals and visitors alike. Explore, locate and identify all the trees and locations of the park in unprecedented detail and artistry with crisp interactivity and location tracking. - Instantly identify 20,000 Trees: Each of the 20,000 central park trees has been positioned and identified as one of 179 species. Co-author Ken Chaya has spent over 2 years carefully mapping out one of the world's richest, most majestic and diverse collection of trees. Just tap the map! - Navigate: Scroll, swipe, pinch and zoom your way around central park with smooth, intuitive navigation. No waiting for incremental downloads or access to WiFi or the Internet... whether you are in the park or on a subway, the map is always available. - Enjoy the Artwork: Depicts every tree, path, rock formation, body of water, building, bridge, archway, statue, monument, recreational area and playground in the most detailed illustrated map of Central Park available. - Interact and Learn: Tap on over 300 individual park sites to access historical facts and practical information about them through illuminating, explanatory captions. - Find Me: Once inside the park, quickly locate your position and direction. Location services need to be available and enabled. - Find It: Search, locate and read about all major points of interest, bridges, statues, playgrounds, food stands, facilities and featured Great Trees with the "find it" option. When in the park and "Find Me" has been selected, the find-it list will show distance and be ordered by closest first. To read details on these points of interest, either tap them directly on the map or choose "Find It" on the bottom of your screen, and then tap the relevant “Show” button. The icons will then display on the map and it will be easy to locate and click on them for information. To hide them, tap on "Show" again".

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.
