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.

TraderSync: AI Trading Journal Most traders repeat the same costly mistake for months without ever seeing it. And most trading ideas never get tested before real money is on the line. TraderSync fixes both. KNOW IF YOUR IDEA WORKS BEFORE YOU RISK MONEY ON IT Tell Cypher your strategy in plain English — no code, no formulas. It runs the idea against years of historical data and shows you how it would have performed. Test a hunch in the time it takes to type it. PRACTICE WITHOUT LOSING A CENT Step through real past sessions bar by bar and trade them as they unfolded. Build the instincts that normally take years — and cost thousands in losses to learn — without putting a dollar at risk. KNOW WHICH SETUPS ACTUALLY PAY Stop guessing which strategies work. See win rate, profit factor and P/L broken down by setup, market, time of day and position size — so you can double down on what works and cut what doesn't. CATCH THE MISTAKES THAT COST YOU MOST Tag mistakes as you log trades and watch the real cost add up. Most traders discover a single recurring error behind a huge share of their losses. ASK CYPHER ANYTHING ABOUT YOUR TRADING Your AI assistant reads your trade history and answers in plain language. Find the patterns buried in months of data without building a single spreadsheet. SEE YOUR PROGRESS AT A GLANCE A dashboard you arrange yourself, a calendar of green and red days, and interactive charts that put every trade in context. BUILT FOR EVERY MARKET YOU TRADE Stocks, Options, Futures, Forex and Cryptocurrency. WHAT'S INSIDE • AI backtesting from plain-English strategy descriptions • Market replay • Performance, daily P/L and trade management reports • Setup, mistake, market, volume, share and price reports • Weekly and monthly breakdowns • Executions, price action, P/L, notes and chart screenshots on every trade • Calendar view of daily and monthly results TraderSync requires an account.

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.
