What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Search by Image is a powerful browser extension for Safari that makes effortless reverse image searches possible, and comes with support for more than 30 search engines, such as Google, Bing, Yandex, Baidu and TinEye. Search by Image is an open source project made possible thanks to a community of awesome supporters. By purchasing the extension on the App Store, you help support the continued development of the extension. The extension helps journalists and researchers verify the authenticity of images, and assists in the identification of false information on social media. Search by Image is also popular among photographers, helping artists explore how their work is shared on the web, while shoppers find it valuable for discovering similar products at discounted prices. The extension enables you to search for images from the browser menu with the help of a diverse set of reverse image search engines, which can be toggled and reordered from the extension's options. Visit the wiki for the full list of supported search engines. https://github.com/dessant/search-by-image/wiki/Search-engines PRO TIPS: • Search with an image by sharing it from Files or Photos. • Tap the Share button in the extension modal to extract an image from a web page and share it to other apps, such as Messages or Notes. You may choose to allow the extension to run on every website, or grant access to the current website before a search. When you grant access only to the current website, access must also be granted to each search engine in order to view search results. Images positioned at the selected area are detected regardless of how they were embedded in the page. The extension also supports searching with images from your device, and images from private sites. A handful of search modes are offered that serve different use cases. The search mode can be configured from the extension's options. Search modes: • Select URL: select an image on the page and search with the image URL. This is the default search mode. • Select image: select an image on the page and search with the image file. This search mode is preferred for sites which do not allow the direct linking of images, such as private sites. • Browse: search with an image from your device. Pasting images from the clipboard is also supported. • URL: search with an image URL. Reviews are not monitored for bug reports, please visit the support page to report issues and submit feature requests.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
