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
In Python Code Develop, you can: - git clone any repository - use Python, or projects with mixed languages FFI, including complex Python / C / NodeJS dependencies to implement your code - run windowed programs offline, supporting almost all current GUI programming frameworks - run Python, C/C++ and other codes offline to test your project - git add, git commit, git push and ssh deployment... No need for any special environment setup, you can fully utilize the native performance of your device and enjoy a desktop-level development experience. We have built-in a complete Linux container environment, including commonly used software packages such as git, ssh, gcc, cmake, etc. Whether you are a novice who just started learning Python or an experienced programmer who needs to fix urgent bugs on a mobile device, you can get started quickly. For the first use, you need to download a Linux image smaller than 1GB, and then you can use it completely offline. Unleash your imagination and create freely in Python Code Develop!

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.

BUILD KIT DIFFICULTY

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.
