Generating… usually about a minute.
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.

Rod Machado’s Instrument Pilot’s Handbook – Second Edition, 626 full color pages Rod Machado's Instrument Pilot's Handbook is a teaching tour de force that takes pilots through the complex world of instrument flying. Long known for his unique ability to transform difficult concepts into simple-yet-complete explanations, Machado takes both new and experienced IFR pilots on a guided tour of instrument flying, from the basics through subtleties that even many professional pilots will find useful. He turns complexity into curiosity. Nearly 1,000 illustrations shine further light on the topic at hand. From how the basic aircraft instruments really work through what's inside a thunderstorm and how a GPS approach works, Machado teaches IFR pilots not just the minimum needed to pass the instrument pilot written exam, but every aspect of IFR flying. This up-to-date text covers the latest information on GPS, glass cockpits, data uplinks, computer-based resources, and other new (and future) technologies and techniques. It is also a rich source of practical information about how real pilots really fly IFR. Readers learn how to gauge the thunderstorm potential of a cumulus cloud by estimating the rainfall rate, scan their instruments in a way that provides maximum performance with minimum effort, and keep the needle centered during an ILS or LPV approach by using the sky pointer on the attitude indicator. There's flying by the book, and then there's flying by THIS book. Rod Machado's Instrument Pilot's Handbook is fun, thorough, and the next best thing to having Rod Machado sit by a pilot's side and talk him through each topic. Once again, Machado proves that you can have fun while learning what you need to know in order to fly safely. As a comprehensive information source book, these pages include: -Simplification of the FAA’s instrument scan concepts and an easy-to-use, cockpit-practical instrument scan technique -Latest information on aviation decision making for instrument pilots -Detailed understanding of analog and glass (PFD) flight instruments -Detailed procedures for planning an IFR cross-country flight -Easy to apply navigation methods for VOR, GPS, ADF and for flying approaches to LPV, LNAV, LNAV/VNAV minimums -Clear, down-to-earth explanations of pertinent FARs, including instrument currency, lost comm, alternate requirements, etc. -Step-by-step explanation of how instrument approach charts are constructed, including MDAs, DAs, procedure turns, etc. -Practical understanding of the IFR system, GPS procedures, icing and thunderstorm avoidance, NEXRAD, RADAR, etc.

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.
