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.

*Online co-op is now available: play with a friend by sharing a code!* Children of Morta is a story-driven action RPG with a roguelite approach to character development, in which you don’t play a single character but a whole, extraordinary family of heroes. Hack’n’slash through hordes of enemies in procedurally generated dungeons, caves and lands and lead the Bergson family, with all their flaws and virtues, against the forthcoming Corruption. The story takes place in a distant land but copes with themes and emotions common to all of us: love and hope, longing and uncertainty, ultimately loss... and sacrifice we are willing to make to save the ones we care the most for. Ultimately, it's about a family of heroes standing together against the encroaching darkness. -- Complete Edition -- Both the Ancient Spirits and the Paws and Claws DLC are included in the main game and available as you play. FEATURES - Welcome to the family! Join the heroic Bergsons in their trials to honor their heritage and save the land of Rea from the creeping Corruption - One for all, all for one: improve skills and gear for the whole family through each run in the ever-changing world of this roguelite RPG - Stronger together: switch between 7 playable characters, each with their own abilities, fighting styles and endearing personality - Immerse yourself in the beautiful, deadly world of Rea through gorgeous 2D pixel art mixing handcrafted animations with modern lighting techniques - Family that slays together stays together: use the two-player online coop mode and rely on each other in every fight (available in a post-launch update) CAREFULLY REDESIGNED FOR MOBILE - Revamped interface – exclusive mobile UI with complete touch control - Game Center achievements - Cloud Save – Share your progress between iOS devices - Compatible with MFi controllers - iPhone 15 Optimization (including Pro Max)

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.
