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.

Morse Command turns Morse code training into a mission. Whether you're studying for your ham radio license, sharpening CW skills for HF contesting, training for military communications, or simply fascinated by the world's most enduring digital language — Morse Command builds real ear-copy proficiency through an addictive tower defense campaign. Enemies fall from above, each carrying a Morse character played as authentic audio. Identify the character, type the letter, and neutralize the threat before it reaches your base. It sounds simple — until Rushers charge, Phantoms vanish, Tanks take multiple hits, and Commanders rally surrounding enemies to move faster. LEARN THE RIGHT WAY — KOCH METHOD Morse Command follows the Koch method, the scientifically proven approach used by military and amateur radio operators worldwide. You start with just two characters at full speed, building instant recognition rather than slow counting. New characters are introduced progressively across 8 themed zones, from Signal Station to Command Center. • 80 campaign levels across 8 zones • 40 characters: full alphabet, numbers 0-9, and punctuation • Characters taught at speed — no bad habits, no crutches • Farnsworth timing that naturally tightens as you advance DAILY DRILL — BUILD UNBREAKABLE HABITS One drill per day. Track your streak, review accuracy, and watch your weakest characters improve over time. The Daily Drill adapts to target the characters you struggle with most, ensuring every session counts. Share your results and compete with friends. REAL MORSE AUDIO — TRAIN YOUR EAR Every character plays as a genuine CW tone with adjustable speed (10–60 WPM) and frequency (400–800 Hz). This isn't a visual flashcard app — you learn to decode Morse code by ear, the way it's actually used on the air. TACTICAL DEPTH Eight distinct enemy types keep you engaged across all 80 levels: • Scouts — standard threats to build your rhythm • Teleporters — blink across the field unpredictably • Rushers — charge at double speed, demanding fast reflexes • Phantoms — fade in and out of visibility • Tanks — absorb multiple hits before going down • Leeches — drain your base health over time • Splitters — break apart when hit • Commanders — boost the speed of all nearby enemies Earn combo-based power-ups: Slow Field, EMP Blast, Repair Kit, and the devastating Nuke. Every zone culminates in an epic boss battle that tests everything you've learned. BUILT FOR OPERATORS • Adjustable WPM and tone frequency to match your rig • Haptic feedback for dit/dah rhythm reinforcement • Detailed stats: per-character accuracy, session history, progress tracking • Streak tracking and performance analytics • Works offline — practice anywhere, anytime WHO IS MORSE COMMAND FOR? → Ham radio operators preparing for CW contests or license exams → Military and emergency communications personnel → Preppers building resilient communication skills → Students, scouts, and anyone who wants to learn Morse code → Experienced CW operators looking to increase copy speed Stop memorizing charts. Start building real Morse code fluency — one mission at a time.

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.
