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.

Truck drivers: save yourself a fine and maximise your driving hours with this advanced tachograph and driving log. TruckerTimer is designed specifically for truck, lorry and HGV drivers in the UK and Europe to help you track your driving hours and alert you to impending fatigue violations. TruckerTimer is designed to keep you legal within the many complex rules of the EU driver's hours regulations. Features: * Supports EU heavy vehicle fatigue regulations * Includes timers for WTD regulations * Rules are suitable for coach drivers also * Graphical countdown for each rule, showing how long you have left * Automatically switch between driving and other work based upon GPS movement * Implements advanced rules: split breaks, 10-hour days twice per week, 15 hour spread and more * Allows manual adjustment of logs in case you forget to switch to rest or driving mode at any time * Gives daily and weekly summaries of all driving activity, able to be offset to match your shift start time. * Ability to set a 15, 30 or 45 minute alarm for short breaks TruckerTimer has seen extensive testing, both in the field and with over 100 synthetic driving logs to ensure that regulations are correctly implemented. Continued use of GPS running in the background can dramatically decrease battery life. GPS use is optional and can be controlled within the application settings. iOS6 users: You will prompted to download an older version. This is currently identical to the most recent version except for updates to the iOS7 style. Updating to iOS7 is recommended to get the quickest updates in the cuture.

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.
