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.

Understanding holding patterns is one of the most challenging parts of instrument flying. Holding Pattern Visualizer makes them simple. Designed for instrument students, CFIs, and pilots looking to refresh their IFR knowledge, this powerful training tool allows you to quickly visualize holding patterns, determine the correct entry, and understand exactly how the aircraft will fly the hold. Whether you're preparing for your instrument rating, teaching students, or getting back up to speed with IFR procedures, Holding Pattern Visualizer turns complex holds into clear, intuitive visuals. Interactive Holding Pattern Visualization Simply enter the information from a clearance or scenario and the app will instantly generate a visual representation of the hold. Input: • Fix • Aircraft heading • Altitude • Holding radial and direction • Wind direction and velocity • Left or right turns The app then automatically generates a clear diagram of the holding pattern including inbound and outbound courses. Entry Sector & Track Visualization Choose how you want to study the hold: • Entry Sector Mode – Displays the direct, teardrop, and parallel sectors • Track Mode – Shows the actual flight path used to fly the hold This makes it easy to understand both which entry to use and how the aircraft will actually fly the maneuver. Automatic Calculations Holding Pattern Visualizer performs the calculations pilots normally have to do mentally: • Determines the correct holding pattern entry • Calculates the inbound course • Displays the outbound course • Computes maximum allowable holding airspeed based on altitude (FAR limits) • Calculates inbound and outbound leg times • Calculates distance flown on each leg Wind Correction Built In Enter wind direction and velocity to visualize how wind affects the hold and adjust your track accordingly. This helps pilots understand how to maintain the correct pattern even in real-world wind conditions. Built for Training • Perfect for instrument rating students • Ideal for CFIs teaching holding patterns • Great refresher for instrument pilots regaining proficiency • Works offline — no internet required Holding Pattern Visualizer was designed by pilots to make one of IFR flying’s most confusing topics clear, visual, and easy to understand. Master holding patterns faster and fly with confidence.

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.
