Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Survivalist.AI is an offline AI assistant and chatbot contained entirely on your iPhone or iPad. That means you have access to useful information anywhere you are without the need for internet. You can use Survivalist.AI while on a plane, at sea, under the ocean, hiking and camping in remote locations, and even in outer space. Some of the things you can ask the AI chat bot: • What to do when I get stung by a bee • Summarize this pasted article • Give me some bodyweight exercises to do • Tell me a scary story • Write me a campfire song • Give me a recipe for blueberry muffins • Write me a short resignation letter • Coding questions like: "give me python code for the fibonnaci sequence" • Excel questions like: "what is the formula to determine if a number is prime" • Explain the following code... We are committed to user privacy. Conversations stay private on your device and are not transmitted anywhere. This is a benefit of having an AI virtual assistant and chatbot running on your phone and not in other computer networks. We carefully curate the Large Language Models (LLMs) that run within the capabilities of your device. These models are trained on billions to trillions of tokens and are extremely processor and memory intensive. As a result, Survivalist.AI works best on the newest iPhones and iPads with 6GB+ of RAM. Survivalist.AI offline chat bot includes the ability to use the following LLMs: TinyLlama, Qwen2, Phi-2, Phi-3, Phi-3.5, Ministral 8B, Mistral 8B, Llama 3, Llama 3 Coder, Llama 3.1, Llama 3.1 Coder, Llama 3.2 3B, Gemma 2 2B, Gemma 2 9B, DeepSeek R1 Phi-2 is included in the download as the default AI model. Llama 3 Coder and Llama 3.1 only run on iPads with 16GB RAM. If you find the app is unresponsive or very slow, please restart it. Please read our terms of service before installing and using this app. Output that Survivalist.ai generates may not be accurate or true due to limitations of the AI model. App has been tested to work on: iPhone 13 Pro, 13 Pro Max, 14, 14 Plus, 14 Pro, 14 Pro Max, 15, 15 Plus, 15 Pro, 15 Pro Max, 16, 16 Pro iPad 12.9" Pro Gen 3, Gen 5, Gen 6 iPad 11" Pro Gen 3, Gen 4 iPad Air Gen 5 Terms of service: https://survivalist.ai/terms-of-service Privacy policy: https://survivalist.ai/privacy-policy

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.

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.
