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.

No ads. No subscriptions. Just the climbing knots you need. Climbing Essentials is a simple, focused reference app designed to help climbers learn, review, and understand the most important climbing knots used in real climbing situations. Whether you’re preparing for your first climb, practicing skills at home, or double-checking a system at the crag, this app provides a clear, reliable guide to the knots climbers use every day. Instead of searching through videos or scattered tutorials, Climbing Essentials gives you clean, step-by-step visual instructions that make it easy to see exactly how each knot is tied. Each knot is paired with a simple explanation of when and why it’s commonly used so you can understand the purpose behind the technique—not just the steps. This app is designed to be fast, simple, and distraction-free, making it an ideal pocket reference for climbers of all levels. Learn the Essential Climbing Knots Climbing Essentials covers many of the most widely used knots in climbing and rope systems, including: • Figure Eight • Bowline • Clove Hitch • Double Fisherman’s • Alpine Butterfly • Prusik • Autoblock • Munter Hitch • Overhand Knot • Water Knot • Girth Hitch • Klemheist • European Death Knot (EDK) • Stopper Knots • and more These knots are commonly used in rock climbing, trad climbing, sport climbing, mountaineering, rappelling, and anchor systems. Step-by-Step Visual Guides Each knot is broken down into clear step-by-step images so you can follow the process easily and see how the rope moves through each stage of tying the knot. This visual approach makes it easier to learn, review, and remember knots compared to text descriptions alone. Common Uses Explained Understanding when to use a knot is just as important as knowing how to tie it. Each knot includes a brief explanation of where it is commonly used in climbing systems, such as: • tying into a harness • building anchors • joining ropes • attaching to carabiners • friction hitches for rappelling or ascending Designed for Climbers Climbing Essentials is built to be a quick reference tool that works when and where you need it. • Clean, distraction-free design • Easy navigation between knots • Fast loading step guides • No unnecessary features Works Offline All knot guides are stored directly in the app so they are available anywhere, even when you don’t have cell service.

Climbing Essentials is designed for climbers who want a simple, reliable guide to the knots that matter most. Learn the knots. Review the fundamentals. Climb 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.
