# Code Farm The Code Farm is a cooperative idle game. Each member owns a farm of plots, plants software projects that build over real time, harvests them for coins and XP, upgrades their CI tier for faster builds, and waters other members' growing builds to speed them up and earn coins. Refactoring (prestige) costs a dynamic coin fee that grows with prestige and current wealth; the fees fill a community treasury from which active low-balance farms can claim a weekly grant. All endpoints negotiate HTML or JSON. POST bodies are form encoded (`application/x-www-form-urlencoded`). Every own-farm action returns `{"ok": true, "farm": {...}}` - the full updated farm state - so a client can refresh without a second request; the two neighbour actions (water, steal) return the neighbour's farm as `{"farm": {...}}`, and a successful steal adds `stole_coins`. An invalid action (not enough coins, wrong plot state, a protected harvest, an active cooldown) returns HTTP 400 as `{"error": {"status": 400, "message": "..."}}`; an unknown farm username is 404. Reading your own farm state also runs lazy owner effects: the CI Bot legacy upgrade auto-harvests ready builds, and any due Defense upkeep is charged. The complete rules, formulas, and an automated client are on the [Code Farm guide](/docs/code-farm.html).
