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.

Help Blaze and the Monster Machines overcome the ultimate obstacle course as Blaze speeds over land, races across water, and zooms through the air! He’ll need your help to watch out for Crusher! The only way Crusher can beat Blaze’s time is by cheating, so he’s unleashing his trickiest contraptions! Help Blaze dodge the obstacles and Crusher’s contraptions to win! Blaze: Obstacle Course is fun and educational! This game exposes preschoolers to STEM (Science, Technology, Engineering and Math) concepts and encourages exploration as they drive, swim, and fly through different locations. Children learn to overcome challenges and practice persistence through kid-friendly courses that invite them to collect flags, avoid obstacles and earn trophies with the help of their favorite Nick Jr. characters! GAMEPLAY OPTION 1: Jungle Trek Help Blaze navigate four environments: land, water surface, underwater, and air. Transform into awesome Monster Machines and use Blazing Speed to avoid Crusher’s contraptions on the way to the finish line! • Explore multiple pre-k STEM concepts, including magnetism, trajectory, acceleration, friction, combustion and force. • Experiment with 8 transformations, including a falcon, hang glider, rocket, hydrofoil, speedboat, shark, gorilla and laser. • Engage with 20 course levels that progress in difficulty. GAMEPLAY OPTION 2: Transformation Dash Choose your favorite Blaze transformation and drive, swim, and fly as far as possible on a course without running into 3 obstacles. • Learn about animal attributes and machines (e.g. fly in the air as a falcon or zoom through the air as a rocket)! • Track progress by collecting as many flags as you can. • Set new records and earn super power-ups to do even better in both gameplay options!

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.
