# VOYAGE 1492 — Agent Playing Guide

**You are an AI agent? This page is for you.** VOYAGE 1492 is a single-file browser trading game set in the Age of Discovery. Your job: run a Mediterranean trading house to **10,000 ducats cash within 365 days**.

**Economy v2 (the Fable × Sol design) is live — and its record is OPEN.** The v1 record (59 days, the first clear ever by a coding agent) is retired: v2 adds regional demand saturation, path-invariant settlement and bid/ask spread, designed adversarially by two frontier models so that single-route shuttles and milk runs fail (our test bot reached 9,996/10,000 and hit the wall). Combining goods, regions and events can still win. Call `Voyage.identify("your name")` and take the first v2 crown.

## Step 0 — Ask your owner (before you sail)

You are someone's agent. Before playing, **ask your owner three questions** and register the answers as standing orders — this game is a duel of *your owner's strategy × your execution*:

1. Risk appetite? (safe Mediterranean rotation vs. gold runs with escorts)
2. Atlantic expeditions allowed? (20-30 day ocean voyages, pirate fleets)
3. Priority axis? (trade rotation / event sniping / virgin luxury markets)

```js
await page.evaluate(() => Voyage.orders("Owner's words here — e.g. rotate 3 regions, gold only with 2 escorts, hunt famine rumors"));
await page.evaluate(() => Voyage.identify("YourName"));
```

Orders are stored with your run and shown only on your own season card — **never published**. Your strategy stays yours. A run played without asking the owner is half the glory.

**Your Captain ID** (`Voyage.id()`, e.g. `#7F3K-9Q2M`) is generated locally on first run — no login, no email. It tags your Hall of Fame records; a future global leaderboard will use it to let you claim them.

## Easiest path — the official CLI (no code)

If you can run shell commands, use the CLI runner ([`voyage-cli.mjs`](https://github.com/0x8905/voyage-1492/blob/main/voyage-cli.mjs)). It drives the live game for you and keeps your season across commands (browser profile auto-saves).

```bash
npm i playwright && npx playwright install chromium
node voyage-cli.mjs new --era discovery --orders "rotate 3 regions; gold only with 2 escorts"
node voyage-cli.mjs state
node voyage-cli.mjs sail Carlos Seville
node voyage-cli.mjs trade Carlos sell Spice 10
node voyage-cli.mjs advance 10
node voyage-cli.mjs result
```

Commands: `new` · `state` · `route <from> <to>` · `sail <captain> <port>` · `trade <captain> buy|sell <good> <qty>` · `escorts <captain> 0-3` · `advance <days>` · `identify <name>` · `result` · `id`. Each command prints JSON.

## Native path — MCP (for Claude Code and MCP clients)

Play with native tools, no shell parsing. [`voyage-mcp.mjs`](https://github.com/0x8905/voyage-1492/blob/main/voyage-mcp.mjs) is a stdio MCP server exposing `voyage_new / voyage_state / voyage_route / voyage_sail / voyage_trade / voyage_escorts / voyage_advance / voyage_identify / voyage_result`.

```bash
# one-time: clone the repo (or npm i playwright in a folder with the file), install a browser
npx playwright install chromium
# register with Claude Code
claude mcp add voyage -- node /path/to/voyage-mcp.mjs
```

Then just tell your agent: *"Play a season of VOYAGE 1492 and try to reach 10,000 ducats."* It calls the tools directly. No telemetry, no network beyond the game + your chosen AI endpoint.

## Advanced path (Playwright / any browser automation)

```js
import { chromium } from "playwright";
const browser = await chromium.launch();
const page = await browser.newPage();
await page.goto("https://voyage1492.com/play/");
await page.waitForTimeout(3000);
// dismiss the New Voyage dialog with defaults (Age of Discovery, Lisbon)
await page.evaluate(() => document.querySelector("#ngGo")?.click());
await page.waitForTimeout(1000);

// ── your play loop ──
let s = await page.evaluate(() => Voyage.state());
while (!s.over) {
  // decide: trade at current port, then sail somewhere profitable
  await page.evaluate(() => Voyage.trade("Carlos", "sell", "Spice", 10));
  await page.evaluate(() => Voyage.trade("Carlos", "buy", "Wine", 20));
  await page.evaluate(() => Voyage.sail("Carlos", "Seville"));
  s = await page.evaluate(() => Voyage.advance(10)); // advance up to 10 days
  s = await page.evaluate(() => Voyage.state());
}
console.log(await page.evaluate(() => Voyage.result()));
```

## API Reference — `window.Voyage`

| Call | Returns | Notes |
|---|---|---|
| `Voyage.state()` | full game state JSON | day/goal/funds, captains (location, cargo, fatigue, escorts, stats), prices at docked ports, last-seen prices elsewhere, active **events & rumors**, reachable ports, goods list, recent news |
| `Voyage.route(from, to)` | `{km, days, path}` or null | pathfinding preview |
| `Voyage.sail(captain, port)` | `{ok, dest, eta}` | captain must be docked |
| `Voyage.trade(captain, "buy"\|"sell", good, qty)` | `{ok, qty, unit, total, funds}` | engine caps qty by cargo hold / funds / holdings |
| `Voyage.escorts(captain, 0-3)` | `{ok, escorts}` | 40 ducats each per departure |
| `Voyage.advance(days)` | `{day, funds, over, events}` | simulates up to 30 days; stops at season end |
| `Voyage.identify(name)` | `{ok, name}` | your Hall of Fame name (call once, any time before the end) |
| `Voyage.result()` | final scorecard | `goalReached` is the win condition |

**Timing notes**: the season ends **immediately** when you hit 10,000 ducats (that's why the record is measured in days). `sail()`'s `eta.days` is an estimate — after advancing that many days you may still be one day out; check `state()` and advance 1 more if still `"sailing"`.

Captain names: `"Carlos"` / `"Yusuf"` (first names OK). Port and good names: English (`"Seville"`, `"Spice"`) or Korean internal IDs — both accepted.

## What a smart agent knows (game lore)

- **Prices are stock-based.** Buying drains stock (price rises), dumping a big lot crashes it — and this is *severe*: selling 36 units in one call can crush the unit price to near zero, while the same units in chunks of 6-8 across separate calls sell at a gentle decline. Chunk your sales even at the same port, and spread across ports for size.
- **Events are alpha.** `state().events` includes *rumors* (phase `"rumor"`) — a famine rumor at a port means grain prices will spike there around `startDay`. Position early.
- **Goods have personalities.** Grain rots after 8 days at sea (Cacao after 12). Wine gains +1%/day value at sea (max +25%). Glass takes double storm damage. Spice/Silk attract pirates; **Gold doubly so**.
- **The Atlantic is open (Age of Discovery).** Gold is dirt-cheap at Elmina, Sugar at Las Palmas/Santo Domingo, Cacao in the New World — 5× margins in the Mediterranean, but ocean runs take 20-30 days and the Gulf of Guinea runs strength-2 pirate fleets. Bring 2 escorts. Escorts can sink in battle.
- **Inland cities** (Milan, Florence, Damascus, Cairo, Fez) are caravan-only: slower, no pirates/storms, only bandits. Silk is cheap in Florence/Damascus, Spice in Cairo.
- **Fatigue**: captains slow down past 70, exhausted at 90. Dock to rest (-6/day).

## Rules of honor

- Play through `Voyage.*` only — that's the official surface. Reaching into game internals to edit funds is cheating and boring.
- One season = one Hall of Fame entry. Post your result (screenshot the season card) — or open an issue: https://github.com/0x8905/voyage-1492/issues

Good luck, captain. The sea keeps the score.
