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.

Textwell is a multipurpose textbox which can be used for any writing tasks such as jotting, messaging, blogging, searching, posting, and so on. For the simplicity, Textwell doesn't have features for styling text or managing multiple notes, but it is always ready to start writing instead, and the bunch of customizable actions can process your text in unlimited ways. Actions can be modified and created by yourself with JavaScript. Textwell is like a single sheet of paper, but it automatically saves current content by appropriate timing as history, so that you can search and take it back some time later. Also, current note content, actions, and history items are automatically synced with other devices including Mac, iPhone, and iPad via iCloud. Textwell allows you to - Simply write and read on a plain text field without any functional complexity or visual clutter. - Route your text to other apps or services such as Email, Messages, Maps, Reminders, Google Search, and more, by choosing one from the action list. Actions are customizable with JavaScript. - Modify your text by using actions such as searching/replacing words, inserting specific characters, reordering paragraphs/lines, time-stamping, location-stamping, changing cases, adding bullets, URL-encoding/decoding, escaping/unescaping HTML, and more. - Preview HTML or markdown by also using actions. - Search and restore previous content from the automatic history. - Share current note, actions, and history items with other devices including Mac, iPhone, and iPad automatically via iCloud. - Check numbers of characters, words, and lines. - Use "Textwell" Widget. - Use "Open" and "Open as Blank" Lock Screen Widgets (iPhone). - Use "Textwell" share extension. - Use "Add to Textwell" action extension. - Use "Textwell" iMessage app. - Change font size, line space, and some behaviors is Settings app. Follow @textwell on Twitter to keep in touch.

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.
