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
Every pickleball game you record becomes a lesson. PB Vision uses AI to turn complete pickleball game videos into shot-by-shot stats, automatic skill ratings, highlights, and coaching cues you can act on. See what's working, uncover what needs attention, and practice with purpose. KNOW EXACTLY HOW YOU RATE Get an overall PB Vision Skill Rating plus detailed ratings for Serve, Return, Offense, Defense, Consistency, and Agility. Track your recent performance and understand how you played - not just whether you won. STUDY THE SHOTS THAT MATTER Use Shot Explorer to find drives, drops, dinks, lobs, Ernes, ATPs, errors, and more. Review shot quality, accuracy, speed, depth, placement, and 3D trajectories without scrubbing through an entire match. SEE THE WHOLE COURT Explore movement, positioning, court coverage, kitchen-line transitions, partner dynamics, and your performance on the left or right side. REVIEW AND SHARE Watch rally-only video, bookmark important moments, draw on screen, create highlights, export clips, and share games with friends, partners, or coaches.

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.

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.
