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.

Your lineup and your assistant coach. Nothing else. (A)ss(I)stant Coach is a deliberately small tool for hockey coaches and general managers. Upload your roster, build your lines, and get an honest read on them before puck drop — without wading through a practice planner, a video library and a team feed to get there. BUILD YOUR LINES • Four forward lines, three defense pairs, starter and backup, PP1, PK1 and scratches — all on one screen • Tap any slot to see your whole bench, with jersey numbers and overall ratings right in the list • Private notes on every line and pair: chemistry, matchups, what to fix. Only you ever see them • Save as many lineups as you want, duplicate one, or pull last game's lines forward in a single tap (A)ss(I)STANT COACH It grades every unit from A+ to D and explains itself in plain hockey language: • "Playmaker with no finisher — give him a shooter" • "Both wingers on their off-wing" • "Nobody at the net front — the goalie sees everything" • "No faceoff specialist for the shorthanded draw" • "#21 Kowalski rates above #19 Fitzgerald — consider dressing him" Then tap Build Best Lineup and it assembles your strongest group: natural positions first, handedness second, your own ratings as the tiebreaker — faceoff men at center, wingers chosen to complement their center, a puck-mover paired with a defender, and your power-play quarterback where he belongs. It runs entirely on your device using your own ratings and trait tags. It is a rules-based assistant, not a chatbot, and your roster never leaves your phone. RATE AND TAG YOUR PLAYERS • Grade skaters on Skating, Shooting, Playmaking, Defense and Compete — goalies on Reflexes, Positioning, Rebound Control and Compete • Tag them from 80+ scouting traits: Sniper, Playmaker, Net-Front Presence, Shutdown, Faceoff Specialist, Power-Play Quarterback, Penalty Killer, Burner, Grinder and more • Broadcast-style player cards rank each player by percentile against your own roster at his position — not against some league average • Archive a season and every player keeps a permanent history, so the cards grow season-over-season trend graphs as your team develops UPLOAD YOUR ROSTER IN SECONDS • Import a CSV from a league site or a spreadsheet, or paste a list straight from a text or an email • Column headers are detected and matched for you • Or add players one at a time — whatever's faster PUBLISH THE CHART • A clean, print-style line chart with your team crest, lines, pairs, goalies, special teams and scratches • Share it as an image, copy the lines as text for the group chat, or AirPrint it for the room • Your private line notes never appear on the published chart YOUR TEAM, YOUR LOGO Upload your own logo once and it shows up everywhere — the line chart you publish, your player cards and your roster. NO ACCOUNT. NO SUBSCRIPTION. NO INTERNET. There is no sign-up, no cloud and nothing to sync. Everything lives on your device, which means it works on the bench, in the barn and on the bus. Built for junior, college, high school, AAA, youth and men's league coaches who just want the lineup part done right.

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.
