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.

Pure instant messaging — simple, fast, secure, and synced across all your devices. One of the top 5 most downloaded apps in the world with over 1 billion active users. FAST: Telegram is the fastest messaging app on the market, connecting people via a unique, distributed network of data centers around the globe. SYNCED: You can access your messages from all your phones, tablets and computers at once. Telegram apps are standalone, so you don’t need to keep your phone connected. Start typing on one device and finish the message from another. Never lose your data again. UNLIMITED: You can send media and files, without any limits on their type and size. Your entire chat history will require no disk space on your device, and will be securely stored in the Telegram cloud for as long as you need it. SECURE: We made it our mission to provide the best security combined with ease of use. Everything on Telegram, including chats, groups, media, etc. is encrypted using a combination of 256-bit symmetric AES encryption, 2048-bit RSA encryption, and Diffie–Hellman secure key exchange. 100% FREE & OPEN: Telegram has a fully documented and free API for developers, open source apps and verifiable builds to prove the app you download is built from the exact same source code that is published. POWERFUL: You can create group chats with up to 200,000 members, share large videos, documents of any type (.DOCX, .MP3, .ZIP, etc.) up to 2 GB each, and even set up bots for specific tasks. Telegram is the perfect tool for hosting online communities and coordinating teamwork. RELIABLE: Built to deliver your messages using as little data as possible, Telegram is the most reliable messaging system ever made. It works even on the weakest mobile connections. FUN: Telegram has powerful photo and video editing tools, animated stickers and emoji, fully customizable themes to change the appearance of your app, and an open sticker/GIF platform to cater to all your expressive needs. SIMPLE: While providing an unprecedented array of features, we take great care to keep the interface clean. Telegram is so simple you already know how to use it. PRIVATE: We take your privacy seriously and will never give any third parties access to your data. You can delete any message you ever sent or received for both sides, at any time and without a trace. Telegram will never use your data to show you ads. For those interested in maximum privacy, Telegram offers Secret Chats. Secret Chat messages can be programmed to self-destruct automatically from both participating devices. This way you can send all types of disappearing content — messages, photos, videos, and even files. Secret Chats use End-to-End Encryption to ensure that a message can only be read by its intended recipient. We keep expanding the boundaries of what you can do with a messaging app. Don’t wait years for older messengers to catch up with Telegram — join the revolution today.

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.
