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
Prediction markets reward edge and speed. PolymarketSignals tracks live prediction-market odds and volume so you can spot opportunities faster. Watch: • Trending markets and price moves, updated live • Odds, 24h volume and liquidity for every question • Volume-based smart-money signals when a market sees an unusual surge • A Trade Scorer with a plain-English read on each side This app is an independent research tool and is not affiliated with, endorsed by, or connected to Polymarket. It does not place bets, hold funds or move money. NOT FINANCIAL OR BETTING ADVICE. Prediction markets are risky — this app is for research and information only. Always do your own research.

Hypothesis 1
Implement user rating and review systems to build trust.
Assumption to check: Lack of user feedback and reviews may deter new users.
Validate with people who use this workflow before building.
Hypothesis 2
Enhance data sources for more comprehensive market signals.
Assumption to check: Limited market signals can lead to poor decision-making.
Validate with people who use this workflow before building.
Hypothesis 3
Improve navigation flow and add onboarding tutorials.
Assumption to check: Difficulties in navigating through different screens.
Validate with people who use this workflow before building.
Hypothesis 4
Introduce community forums or chat for users to discuss signals.
Assumption to check: No community engagement features for users.
Validate with people who use this workflow before building.
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
Intermediate
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.
