+name: Create Game Module
+description: Create a runnable logic module for a board game with 'boardgame-core', '@preact/signals' and 'mutative'
+---
+# 如何编写游戏模组
+
+## 必须导出的接口
+
+```typescript
+import { IGameContext, createGameCommandRegistry } from '@/index';
+
+export type GameState = { /* 你的状态类型 */ };
+export type Game = IGameContext<GameState>;
+
+export function createInitialState(): GameState { /* ... */ }
+export async function start(game: Game) { /* 游戏主循环 */ }
+```
+
+或导出为 `GameModule` 对象：
+```typescript
+export const gameModule: GameModule<GameState> = { registry, createInitialState, start };
+```
+
+## 流程
+
+### 0. 确认规则
+
+在 `rule.md` 中描述：主题、配件、布置形式、游戏流程、玩家行动、胜利条件。
+
+### 1. 创建类型 (`types.ts`)
+
+- 使用字符串枚举表示游戏概念（如 `PlayerType = 'X' | 'O'`）
+- 使用 `Part<TMeta>` 表示配件（棋子、卡牌等）
+- 使用 `Region` 表示区域（棋盘、牌堆等）
+- 状态必须可序列化（不支持函数、`Map`、`Set`）
+
+```typescript
+import { Part, Region } from '@/index';
+
+export type Piece = Part<{ owner: 'X' | 'O' }>;
+export type GameState = {
+    board: Region;
+    pieces: Record<string, Piece>;
+    currentPlayer: 'X' | 'O';
+    turn: number;
+    winner: 'X' | 'O' | null;
+};
+```
+
+### 2. 创建配件
+
+少量配件直接在代码创建：
+```typescript
+const pieces = createParts({ owner: 'X' }, (i) => `piece-${i}`, 5);
+```
+
+大量配件使用 CSV：
+```csv
+# parts.csv
+type,player,count
+string,string,int
+kitten,white,8
+```
+```typescript
+import parts from "./parts.csv";
+const pieces = createPartsFromTable(parts, (item, i) => `${item.type}-${i}`, (item) => item.count);
+```
+
+### 3. 创建 Prompts
+
+```typescript
+export const prompts = {
+    play: createPromptDef<['X' | 'O', number, number]>(
+        'play <player> <row:number> <col:number>',
+        '选择下子位置'
+    ),
+};
+```
+
+Schema 语法：`<param>` 必需，`[param]` 可选，`[param:type]` 带验证。详见 [API 参考](./references/api.md)。
+
+### 4. 创建游戏流程
+
+```typescript
+export async function start(game: Game) {
+    while (!game.value.winner) {
+        const { row, col } = await game.prompt(
+            prompts.play,
+            (player, row, col) => {
+                if (player !== game.value.currentPlayer) throw '无效玩家';
+                if (!isValidMove(row, col)) throw '无效位置';
+                if (isCellOccupied(game, row, col)) throw '位置已被占用';
+                return { row, col };
+            },
+            game.value.currentPlayer
+        );
+
+        game.produce((state) => {
+            state.pieces[`p-${row}-${col}`] = { /* ... */ };
+        });
+
+        const winner = checkWinner(game);
+        if (winner) {
+            game.produce((state) => { state.winner = winner; });
+            break;
+        }
+
+        game.produce((state) => {
+            state.currentPlayer = state.currentPlayer === 'X' ? 'O' : 'X';
+            state.turn++;
+        });
+    }
+    return game.value;
+}
+```
+
+**注意事项：**
+- `game.produce(fn)` 同步更新，`game.produceAsync(fn)` 异步更新（等待动画）
+- 验证器抛出字符串表示失败，返回值表示成功
+- 玩家取消时 `game.prompt()` 抛出异常
+- 循环必须有明确退出条件
+
+### 5. 创建测试
+
+位于 `tests/samples/<game-name>.test.ts`：
+
+```typescript
+import { describe, it, expect } from 'vitest';
+import { createGameContext } from '@/core/game';
+import { registry, createInitialState } from './my-game';
+
+describe('My Game', () => {
+    function createTestContext() {
+        return createGameContext(registry, createInitialState());
+    }
+
+    it('should perform action correctly', async () => {
+        const game = createTestContext();
+        await game.run('play X 0 0');
+        expect(game.value.pieces['p-0-0']).toBeDefined();
+    });
+
+    it('should fail on invalid input', async () => {
+        const game = createTestContext();
+        const result = await game.run('invalid');
+        expect(result.success).toBe(false);
+    });
+
+    it('should complete a full game cycle', async () => {
+        // 模拟完整游戏流程，验证胜利条件
+    });
+});
+```
+
+**要求：**
+- 每种游戏结束条件、玩家行动、边界情况各至少一条测试
+- 使用 `createGameContext(registry, initialState)` 创建上下文
+- 使用 `game.run('command')` 执行命令，验证 `game.value` 状态
+- 测试命名使用 `should...` 格式，异步测试用 `async/await`
+
+**运行测试：**
+```bash
+npm run test:run                              # 所有测试
+npx vitest run tests/samples/my-game.test.ts  # 特定文件
+npx vitest run -t "should perform"            # 特定用例
+```

+
+本文档记录游戏模组开发者需要使用的公共 API。
+
+## 核心接口
+
+### `IGameContext<TState>`
+
+游戏运行的核心上下文，提供状态访问、随机数、命令执行和提示系统。
+
+```typescript
+interface IGameContext<TState extends Record<string, unknown> = {}> {
+    readonly value: TState;                           // 当前游戏状态（只读）
+    readonly rng: ReadonlyRNG;                        // 随机数生成器（只读）
+
+    // 状态更新
+    produce(fn: (draft: TState) => void): void;       // 同步变更状态（基于 mutative）
+    produceAsync(fn: (draft: TState) => void): Promise<void>;  // 异步变更状态（等待中断）
+
+    // 命令执行
+    run<T>(input: string): Promise<CommandResult<T>>;           // 执行命令字符串
+    runParsed<T>(command: Command): Promise<CommandResult<T>>; // 执行已解析的命令
+
+    // 提示系统
+    prompt<TResult, TArgs>(
+        def: PromptDef<TArgs>,
+        validator: PromptValidator<TResult, TArgs>,
+        currentPlayer?: string | null
+    ): Promise<TResult>;
+}
+```
+
+**使用示例：**
+
+```typescript
+// 读取状态
+const currentPlayer = game.value.currentPlayer;
+
+// 同步更新状态
+game.produce((state) => {
+    state.score += 10;
+});
+
+// 异步更新状态（等待动画完成）
+await game.produceAsync((state) => {
+    state.phase = 'next';
+});
+
+// 等待玩家输入
+const result = await game.prompt(
+    prompts.move,
+    (from, to) => {
+        if (!isValidMove(from, to)) {
+            throw '无效移动';
+        }
+        return { from, to };
+    }
+);
+```
+
+---
+
+### `GameModule<TState, TResult>`
+
+游戏模块的类型定义，这是开发者创建游戏时需要导出的核心结构。
+
+```typescript
+type GameModule<TState extends Record<string, unknown>, TResult = unknown> = {
+    registry?: CommandRegistry<IGameContext<TState>>;  // 可选的命令注册表
+    createInitialState: () => TState;                   // 创建初始状态
+    start: (ctx: IGameContext<TState>) => Promise<TResult>;  // 游戏主循环
+}
+```
+
+---
+
+### `createGameCommandRegistry<TState>()`
+
+创建游戏命令注册表，游戏模组用它来注册自定义命令。
+
+```typescript
+function createGameCommandRegistry<TState extends Record<string, unknown> = {}>(): CommandRegistry<IGameContext<TState>>
+```
+
+**使用示例：**
+
+```typescript
+import { createGameCommandRegistry, IGameContext } from '@/index';
+
+export type GameState = { score: number };
+export const registry = createGameCommandRegistry<GameState>();
+
+// 注册命令
+registry.register('addScore <amount:number>', async function(ctx, amount) {
+    ctx.produce((state) => {
+        state.score += amount;
+    });
+    return { success: true, result: undefined };
+});
+```
+
+---
+
+## 提示系统
+
+### `createPromptDef<TArgs>(schema, hintText?)`
+
+从字符串模式创建 `PromptDef`。
+
+```typescript
+function createPromptDef<TArgs>(
+    schema: CommandSchema | string,
+    hintText?: string
+): PromptDef<TArgs>
+```
+
+**使用示例：**
+
+```typescript
+import { createPromptDef } from '@/index';
+
+export const prompts = {
+    // 必需参数
+    play: createPromptDef<[PlayerType, number, number]>(
+        'play <player> <row:number> <col:number>',
+        '选择下子位置'
+    ),
+
+    // 可选参数
+    draw: createPromptDef<[number?]>(
+        'draw [count:number]',
+        '抽牌'
+    ),
+
+    // 带选项
+    trade: createPromptDef<[string, string]>(
+        'trade <give> <receive> [--force]',
+        '交易'
+    ),
+};
+```
+
+---
+
+### `PromptDef<TArgs>`
+
+提示定义，用于 `context.prompt()` 方法。
+
+```typescript
+type PromptDef<TArgs extends any[] = any[]> = {
+    schema: CommandSchema;    // 命令模式定义
+    hintText?: string;        // 可选的提示文本
+}
+```
+
+---
+
+### `PromptValidator<TResult, TArgs>`
+
+提示验证函数类型。验证器函数接收解析后的参数，应返回结果或抛出字符串错误。
+
+```typescript
+type PromptValidator<TResult, TArgs extends any[] = any[]> = (...params: TArgs) => TResult;
+```
+
+**验证器规则：**
+- 返回任意值表示验证成功，该值将作为 `prompt()` 的返回值
+- 抛出字符串错误表示验证失败，错误消息会返回给玩家，玩家可重新输入
+- 玩家取消输入时，`prompt()` 会抛出异常
+
+---
+
+### `PromptEvent`
+
+提示事件对象，通过 `commandRunnerContext.on('prompt', handler)` 监听。
+
+```typescript
+type PromptEvent = {
+    schema: CommandSchema;
+    hintText?: string;
+    currentPlayer: string | null;
+    tryCommit: (commandOrInput: Command | string) => string | null;  // null=成功，string=错误消息
+    cancel: (reason?: string) => void;
+}
+```
+
+---
+
+## 零件系统 (Part)
+
+### `Part<TMeta>`
+
+游戏中的可操作物件（棋子、卡牌、骰子等）。
+
+```typescript
+type Part<TMeta = {}> = {
+    id: string;                    // 唯一标识
+    sides?: number;                // 总面数（用于骰子/多面牌）
+    side?: number;                 // 当前面
+    alignments?: string[];         // 可用对齐方式
+    alignment?: string;            // 当前对齐方式
+    regionId: string;              // 所属区域 ID
+    position: number[];            // 在区域中的位置坐标
+} & Immutable<TMeta>;             // 自定义元数据（不可变）
+```
+
+**使用示例：**
+
+```typescript
+import { Part } from '@/index';
+
+export type PieceMeta = {
+    owner: 'X' | 'O';
+    type: 'pawn' | 'king';
+};
+
+export type Piece = Part<PieceMeta>;
+
+// 访问元数据
+const piece: Piece = ...;
+console.log(piece.owner);  // 'X'

+### `Region`
+
+游戏区域（棋盘、手牌区等）。
+
+```typescript

+```
+
+---
+
+## 命令系统 (Command System)
+
+### `Command`
+
+解析后的命令对象。
+
+```typescript
+type Command = {
+    name: string;                                    // 命令名
+    flags: Record<string, true>;                     // 标志（如 --verbose）

+    flags: Record<string, CommandFlagSchema>;
+}
+```
+
+---
+
+### `CommandResult<T>`
+
+命令执行结果（判别联合类型）。

+}
+```
+
+---
+
+### `CommandDef<TContext, TFunc>`
+
+命令定义对象，用于 `registry.register()`。
+
+```typescript
+type CommandDef<TContext, TFunc extends CommandFunction<TContext>> = {
+    schema: string | CommandSchema;
+    run: TFunc;
+}

+    ctx.produce((state) => { /* 修改状态 */ });
+    return { success: true, result: undefined };
+});
+
+// 方式 2：使用 CommandDef 对象

+```
+
+---
+
+### `parseCommand(input, schema?)`
+
+解析命令字符串为 `Command` 对象。
+
+```typescript
+function parseCommand(input: string, schema?: CommandSchema): Command
+```
+
+---
+
+### `parseCommandSchema(schemaStr, name?)`
+
+从字符串模式解析命令模式。
+
+```typescript
+function parseCommandSchema(schemaStr: string, name?: string): CommandSchema
+```
+
+**Schema 语法：**

+- `[param:type]` - 带类型验证的参数（如 `[count:number]`）
+- `--option:value` - 必需选项
+- `[-o value]` - 可选选项
+- `[--flag]` - 可选标志
+
+---
+
+## 随机数生成器 (RNG)
+
+### `ReadonlyRNG`
+
+只读 RNG 接口（`IGameContext.rng` 返回此类型）。
+
+```typescript
+interface ReadonlyRNG {
+    next(max?: number): number;     // [0,1) 随机数，或 [0,max)
+    nextInt(max: number): number;   // [0,max) 随机整数
+}
+```
+
+---
+
+### `RNG`
+
+可设置种子的 RNG 接口。
+
+```typescript
+interface RNG extends ReadonlyRNG {
+    setSeed(seed: number): void;
+    getSeed(): number;
+}
+```
+
+**使用示例：**
+
+```typescript
+// 在 IGameContext 中使用
+const roll = game.rng.nextInt(6) + 1;  // 1-6 的随机数
+
+// 在区域操作中使用时
+shuffle(region, parts, rng);  // 需要传入 RNG
+```
+
+---
+
+## 可变信号 (MutableSignal)
+
+### `MutableSignal<T>`
+
+扩展自 Preact Signal 的可变信号类，支持 mutative-style 的 `produce` 方法。
+
+```typescript
+class MutableSignal<T> extends Signal<T> {
+    produce(fn: (draft: T) => void): void;
+    addInterruption(promise: Promise<void>): void;    // 添加中断 Promise（用于动画等待）
+    clearInterruptions(): void;                        // 清除所有中断
+    produceAsync(fn: (draft: T) => void): Promise<void>;  // 等待中断后更新状态
+}
+```
+
+---
+
+### `mutableSignal<T>(initial?, options?)`
+
+创建可变信号。
+
+```typescript
+function mutableSignal<T>(initial?: T, options?: SignalOptions<T>): MutableSignal<T>
+```
+
+---
+
+## 游戏主机 (GameHost)
+
+### `GameHost<TState, TResult>`
+
+游戏会话的生命周期管理器。
+
+```typescript

+### `GameHostStatus`
+
+```typescript
+type GameHostStatus = 'created' | 'running' | 'disposed';
+```
+
+---
+
+### `createGameHost<TState>(gameModule)`
+
+从游戏模块创建 `GameHost` 实例。
+
+```typescript
+function createGameHost<TState extends Record<string, unknown>>(
+    gameModule: GameModule<TState>
+): GameHost<TState>
+```
+
+**使用示例：**
+
+```typescript
+import { createGameHost } from '@/index';
+import { gameModule } from './my-game';
+
+const host = createGameHost(gameModule);
+
+// 启动游戏
+const result = await host.start(42);  // 传入种子
+
+// 提交玩家输入
+const error = host.tryInput('play X 0 0');
+if (error) {
+    console.error('输入错误:', error);
+}
+
+// 监听事件
+host.on('start', () => console.log('游戏开始'));
+host.on('dispose', () => console.log('游戏结束'));
+
+// 销毁游戏
+host.dispose();
+```
+

+
+## Preact Signals 重新导出
+
+```typescript
+export * from '@preact/signals-core';
+```
+
+开发者可直接使用 `@preact/signals-core` 的所有导出，包括：
+- `Signal<T>` - 基础信号类
+- `ReadonlySignal<T>` - 只读信号类型
+- `signal<T>(value)` - 创建信号
+- `computed<T>(fn)` - 创建计算信号
+- `effect(fn)` - 创建副作用
+- `batch(fn)` - 批量更新
+- `untracked(fn)` - 非追踪读取
+
+---
+
+## 测试辅助函数
+
+以下函数主要用于测试代码：
+
+### `createGameContext(options)`
+
+创建游戏上下文实例。
+
+```typescript
+function createGameContext<TState>(options: {
+    initialState: TState;
+    registry?: CommandRegistry<IGameContext<TState>>;
+    rng?: RNG;
+}): IGameContext<TState>
+```
+
+**使用示例：**
+
+```typescript
+import { createGameContext } from '@/core/game';
+import { createInitialState, registry } from './my-game';
+
+const ctx = createGameContext({
+    initialState: createInitialState(),
+    registry,
+});
+
+// 执行命令
+await ctx.run('move piece1 piece2');
+
+// 断言状态
+expect(ctx.value.score).toBe(10);
+```
+
+---
+
+### `createTestContext()`
+
+创建用于测试的游戏上下文（简化版）。
+
+```typescript
+function createTestContext<TState>(initialState: TState): IGameContext<TState>
+```
+
+---
+
+### `createTestRegion()`

 ## Commands
 
-Prefer `bash.exe`(C:\Users\Administrator\AppData\Local\Microsoft\WindowsApps\bash.exe) over Powershell.
+Shell environment: git bash (bash.exe) on Windows.
 
 ```bash
-npm run build        # Build ESM bundle + declarations to dist/
+npm run build           # ESM bundle + declarations to dist/ (tsup)
-npm run test         # Run vitest in watch mode
+npm run build:samples   # Build samples separately (tsup.samples.config.ts)
-npm run test:run     # Run vitest once (no watch)
+npm run test            # vitest in watch mode
-npm run typecheck    # Type-check without emitting (tsc --noEmit)
+npm run test:run        # vitest once (no watch)
+npm run typecheck       # tsc --noEmit
 ```
 
-### Running a single test file
+Run a single test file: `npx vitest run tests/core/game.test.ts`
-```bash
+Run tests matching a name: `npx vitest run -t "should create"`
-npx vitest run tests/samples/tic-tac-toe.test.ts
+
+`npm run prepare` runs `npm run build` on install — if `inline-schema` isn't available, installs will fail.
+
+## Local Dependency
+
+`inline-schema` is a **local peer dependency** at `file:../inline-schema` — must exist as a sibling directory before `npm install`. Both vitest and tsup load custom plugins from it (`inline-schema/csv-loader/rollup` and `inline-schema/csv-loader/esbuild`). `yarn-spinner-loader` is also a local dependency at `file:../yarn-spinner-loader` — it can be changed and published if needed. It provides vitest and tsup/esbuild plugins for `.yarnproject` dialogue files.
+
+## Architecture
+
+- **MutableSignal\<T\>**: extends Preact Signal — `.value` to read, `.produce(draft => ...)` to mutate (uses `mutative`). `.produceAsync()` awaits interruption promises first, then mutates.
+- **GameHost**: lifecycle manager — `start(seed?)`, `tryInput(string)`, `tryAnswerPrompt(def, ...args)`, `dispose()`. Reactive signals: `state`, `status`, `activePromptSchema`, `activePromptPlayer`, `activePromptHint`.
+- **GameModule**: `{ registry?, createInitialState, start }`. `registry` defaults to `createGameCommandRegistry()` if omitted.
+- **Command system**: CLI-style parsing with schema validation via `inline-schema`. `CommandRunner.run()` uses `this` bound to a `CommandRunnerContext`.
+- **Prompt system**: `game.prompt(def, validator, currentPlayer?)` — validator **throws a string** to reject, **returns a value** to accept. `PromptEvent.tryCommit(Command | string)` returns `null` on success, error string on failure. `promptEnd` event fires after resolve or cancel.
+- **Part collections**: `Record<string, Part<TMeta>>` keyed by ID. `Object.values()` for iteration, `Object.keys()` for count/IDs.
+- **Region system**: `createRegion()` factory; `partMap` maps position keys to part IDs.
+- **Barrel exports**: `src/index.ts` is the single public API surface.

 ```
 
-### Running a single test by name
+`src/global.d.ts` — `*.yarnproject` module declaration.
-```bash
+
-npx vitest run -t "should detect horizontal win for X"
+`testsgames/` and `testsrules/` — empty directories (reserved).
-```
+
+## Samples Build
+
+`tsup.samples.config.ts` auto-discovers entries from `src/samples/` (directories → `index.ts`, files → direct `.ts`). It rewrites `@/core/*`, `@/utils/*`, and `@/index` imports to external `boardgame-core`.
 
 ## Code Style
 
-### Imports
+- Double quotes for local imports, single quotes for npm packages
-- Use **double quotes** for local imports, **single quotes** for npm packages
+- `@/*` alias maps to `src/*` (configured in tsconfig, vitest, and tsup)
-- Use `@/**/*` for `./src/**/*` import alias
+- Group imports: npm packages first, then local `@/` imports, separated by blank line
-- Use `@/index` for code in `samples`
+- 4-space indentation, semicolons, trailing commas in multi-line
+- Arrow functions for callbacks; `function` keyword for methods needing `this` (e.g. command handlers)
+- Strict TypeScript — no `any`; type aliases for object shapes (not interfaces)
+- Discriminated unions for results: `{ success: true; result: T } | { success: false; error: string }`
+- Derive state types via `ReturnType<typeof createInitialState>`
+- Factory function prefix: `create` or `mutable` — `createGameHost`, `mutableSignal`
+- Validation error messages in Chinese (e.g. `"参数不足"`)
 
-### Formatting
+## Testing
-- **4-space indentation**
-- **Semicolons** at statement ends
-- **Arrow functions** for callbacks; `function` keyword for methods needing `this` (e.g. command handlers)
-- No trailing whitespace
 
-### Naming Conventions
+- Vitest with globals enabled, but **test files import explicitly**: `import { describe, it, expect } from 'vitest'`
-- **Types/Interfaces**: `PascalCase` — `Part`, `Region`, `Command`, `IGameContext`
+- Use `@/` imports in test files (vitest resolve alias)
-- **Classes**: `PascalCase` — `Entity`, `AsyncQueue`, `Mulberry32RNG`
+- Command/prompt test pattern: `waitForPrompt(ctx)` → `promptEvent.tryCommit(Command)` → returns `null` | error string
-- **Functions**: `camelCase`, verb-first — `createGameContext`, `parseCommand`, `isValidMove`
+- No mocking — real implementations. Define inline helpers (`createTestContext()`, `waitForPrompt()`) per file.
-- **Variables**: `camelCase`
+- Narrow result types: `if (result.success)` before accessing `result.result`
-- **Constants**: `UPPER_SNAKE_CASE` — `BOARD_SIZE`, `WINNING_LINES`
-- **Test files**: `*.test.ts` mirroring `src/` structure under `tests/`
-
-### Types
-- **Strict TypeScript** is enabled — no `any`
-- Use **generics** heavily: `Entity<T>`, `CommandRunner<TContext, TResult>`
-- Use **type aliases** for object shapes (not interfaces)
-- Use **discriminated unions** for results: `{ success: true; result: T } | { success: false; error: string }`
-- Use `unknown` for untyped values, narrow with type guards or `as`
-
-### Error Handling
-- Prefer **result objects** over throwing: return `{ success, result/error }`
-- When catching: `const error = e as Error;` then use `error.message`
-- Use `throw new Error(...)` only for truly exceptional cases
-- Validation error messages are in Chinese (e.g. `"参数不足"`)
-
-### Testing
-- **Vitest** with globals enabled (`describe`, `it`, `expect` available without import)
-- Use `async/await` for async tests
-- Narrow result types with `if (result.success)` before accessing `result.result`
-- Define inline helper functions in test files when needed
-- No mocking — use real implementations
-- Test helpers: `createTestContext()`, `createTestRegion()`
-
-## Architecture Notes
-
-- **Reactivity**: `Entity<T>` extends Preact Signal — access state via `.value`, mutate via `.produce(draft => ...)`
-- **Command system**: CLI-style parsing with schema validation via `inline-schema`
-- **Prompt system**: Commands prompt for input via `PromptEvent` with `resolve`/`reject`
-- **Barrel exports**: `src/index.ts` is the single public API surface

+# Onitama
+
+## 游戏目标
+
+玩家在棋盘上移动棋子，达成两种胜利条件当中的一种即可赢得游戏：
+- 占领：将师父棋子移动到对手师父棋子的初始位置
+- 吃掉：将对手的师父棋子吃掉
+
+## 游戏配件
+
+公共配件：
+- 卡牌：16张，每张标记一位起始玩家，和一个移动方式图示
+- 棋盘：1个，5x5
+
+玩家配件：
+- 师父棋子：1个
+- 徒弟棋子：4个
+
+## 游戏布置
+
+1. 将所有玩家的棋子放在棋盘的初始位置上：
+```
+bbBbb
+.....
+.....
+.....
+rrRrr
+```
+其中b表示黑方，r表示红方，大写表示师父，小写表示徒弟。
+
+2. 将所有卡牌洗混，每名玩家抓2张放在自己面前。
+
+3. 翻开一张卡牌作为额外卡牌。额外卡牌标记的玩家成为起始玩家。
+
+## 游戏进行
+
+从起始玩家开始，轮流进行以下步骤：
+- 选择一张卡牌，按照其描述移动棋子。
+- 将选择的卡牌与额外卡牌交换。
+
+移动时，可以选择自己的任意棋子。
+移动落点必须是空位或者对手的棋子。
+若移动到对手的棋子上，则吃掉该棋子。
+
+若玩家没有任何能够进行的移动，可以任意选择一张卡牌与额外卡牌交换，然后直接结束回合。
+
+之后若有玩家达成胜利条件，游戏结束。

+# Regicide (弑君游戏)
+
+## 游戏概述
+
+**Regicide** 是一个合作式奇幻主题卡牌游戏，使用标准扑克牌进行游戏。
+
+- **玩家人数：** 1-4 人（合作）
+- **年龄：** 10+
+- **游戏时间：** 约30分钟
+
+## 游戏目标
+
+玩家们协作对抗，使用手牌击败12个强大的敌人（每个等级3个敌人）。如果成功击败所有12个敌人则获胜；如果任何敌人的生命值归零前未能击败它，或者牌库耗尽时仍有敌人存活，则游戏失败。
+
+## 游戏配件
+
+- **标准扑克牌：** 52张（不包含大小王）
+
+## 卡牌说明
+
+### 数字牌（A-10）
+- 面值等于牌面数字
+- 每张牌有独特的花色能力
+
+### 人头牌（J、Q、K）
+- **J（侍卫）：** 面值 10
+- **Q（皇后）：** 面值 15
+- **K（国王）：** 面值 20
+
+### 花色能力
+- **黑桃（Spades）：** 降低敌人的攻击力
+- **红心（Hearts）：** 将弃牌堆的牌洗回酒馆牌堆
+- **方块（Diamonds）：** 从酒馆牌堆抓牌
+- **梅花（Clubs）：** 造成双倍伤害
+
+## 游戏设置
+
+0. 将所有的J/Q/K从牌堆移出，将4张K洗混后放在最下，4张Q洗混后放在中间，4张J洗混后放在最上形成敌人牌堆
+1. 将剩余的扑克牌洗匀形成酒馆牌堆，每位玩家抽取 6 张手牌
+2. 翻开一张敌人牌
+3. 决定起始玩家（单人模式下自动为当前玩家）
+
+## 游戏流程
+
+从起始玩家开始，轮流进行以下操作：
+
+### 玩家回合
+在你的回合，你可以：
+1. **打出一张牌：** 选择一张手牌打出，对其目标敌人造成伤害或触发效果
+2. **打出一张A和另一张牌：** A可以配合任何其他牌一起打出
+3. **让过（Pass）：** 不出牌，结束回合
+
+### 出牌流程
+1. 打出的牌对当前敌人造成伤害
+2. 触发牌的花色能力
+3. 如果敌人的生命值降至0或以下，该敌人被击败，放置到弃牌堆
+4. 如果当前敌人被击败，翻开下一张敌人牌，否则受到敌人反击，必须弃掉点数和大于等于敌人攻击力的手牌
+
+即使玩家让过，也会受到敌人的反击。
+
+### 限制
+- 玩家之间不能交流或暗示关于手牌的信息
+- 每个回合只能打出一张牌（除了A配合其他牌的情况）
+
+## 敌人机制
+
+### 敌人属性
+- **生命值：** 敌人需要承受的伤害量，为卡牌面值的两倍
+- **攻击力：** 敌人的面值即敌人的攻击力
+
+## 胜利与失败条件
+
+### 胜利条件
+- 击败所有12个敌人
+
+### 失败条件
+- 任何玩家在敌人反击后无法弃掉点数和达到敌人攻击力以上的牌
+- 任何玩家无法出牌

+# AGENTS.md - slay-the-spire-like
+
+Roguelike deckbuilder combining Slay the Spire combat with Backpack Hero grid inventory.
+
+## Architecture
+
+Three-layer design: **system** (content-agnostic) → **data** (CSV content) → **dialogues** (Yarn Spinner).
+
+### System Layer (`system/`)
+
+| Module | Files | Responsibility |
+|---|---|---|
+| `combat/` | types.ts, effects.ts, triggers.ts, prompts.ts | Combat state, effects pipeline, middleware triggers |
+| `deck/` | types.ts, factory.ts, index.ts | Deck state management |
+| `grid-inventory/` | types.ts, transform.ts, index.ts | Grid backpack, shape collision, adjacency |
+| `map/` | types.ts, generator.ts, index.ts | Procedural node generation (point crawl) |
+| `progress/` | types.ts, encounter.ts, index.ts | Adventure progress, node traversal |
+| `utils/` | parse-shape.ts, shape-collision.ts | Shape parsing and collision detection |
+| `types.ts` | — | `EffectData`, `EffectLifecycle`, `EnemyData`, `CardData`, `IntentData`, `EncounterData`, `ItemData` |
+
+### Data Layer (`data/desert/`)
+
+All content via CSV (loaded by `inline-schema`):
+
+| File | Content |
+|---|---|
+| `card.csv` | Card definitions |
+| `effect.csv` | Effect definitions |
+| `enemy.csv` | Enemies + intents |
+| `intent.csv` | Intent definitions |
+| `item.csv` | Equipment items |
+| `encounter.csv` | Encounter nodes |
+
+### Triggers (`data/desert/triggers/`)
+
+Middleware hooks extending the base trigger system:
+
+| File | Hooks |
+|---|---|
+| `effect.ts` | Orchestrator — calls all sub-modules |
+| `instant.ts` | `onEffectApplied` — attack, draw, gainEnergy, removeWound, summon, etc. |
+| `damage.ts` | `onDamage` — block, spike, expose, aim, roll, charge, molt, tailSting, energyDrain |
+| `turn-start.ts` | `onTurnStart` — discard, defendNext, energyNext, drawNext |
+| `card-events.ts` | `onEnemyIntent`, `onCardPlayed`, `onCardDiscarded`, `onDamage` — storm, crossbow, burnForEnergy, sandwormKing, vulture |
+
+### Dialogue Layer (`data/desert/dialogues/`)
+
+`story.yarn` — branching encounter dialogues (inside `dialogues.yarnproject`). Commands resolve via `tryAnswerPrompt`.
+
+## Key Mechanics
+
+- **Energy**: 3/turn, spent on weapon/armor/tool cards
+- **Uses**: Consumable cards use `uses` cost type instead of energy; tracked as `depletion` on `GameItemMeta`
+- **Grid adjacency**: Items buff adjacent items (e.g. burnForEnergy consumes adjacent item on card play)
+- **Effect lifecycles**: `instant`, `temporary`, `lingering`, `permanent`, `posture`, `item`, `itemTemporary`, `itemUntilPlay`, `itemUntilDiscard`, `itemPermanent`
+- **Trigger pipeline**: `createMiddlewareChain` with `use(async (ctx, next) => ...)` pattern
+- **Cards from items**: `GameCard` instances are generated from `GameItem` inventory items via deck factory
+
+## Testing
+
+Tests live in `tests/samples/slay-the-spire-like/`:
+- `combat/effects.test.ts` — effect application, upkeep, posture damage
+- `combat/triggers.test.ts` — full desert trigger integration tests
+- `deck/factory.test.ts` — deck creation
+- `grid-inventory.test.ts` — placement, adjacency, collision
+- `map/generator.test.ts` — procedural generation
+- `utils/shape-utils.test.ts` — shape parsing
+- `data/index.test.ts` — data loading validation

+# 杀戮尖塔 + 背包英雄
+
+玩家有4x6的背包
+
+装备占格子，提供同等数量的牌，并且给周围加buff，背包英雄style
+
+战斗时玩杀戮尖塔
+
+## 肉鸽结构
+
+区域点到点地图
+
+- 分4个区域，每个区域有独立的随机遭遇池，目前先考虑第一个区域
+- 每区域10层，26个遭遇节点
+    - 荒野层6层×3节点（小怪50%/精英25%/事件25%）
+    - 聚落层2层×4节点（≥1篝火/≥1商店/≥1奇遇，第4随机）
+    - 起点→终点，终点为boss战
+
+## 战斗（小怪、精英、boss）
+
+基本流程
+- 怪物战斗开始效应
+- 玩家战斗开始效应
+- 重复直至一方不剩下存活角色
+    - 玩家回合
+    - 怪物回合
+
+怪物战斗开始
+- 获得初始buff、初始血量、初始意图
+
+玩家战斗开始
+- 获得3点能量，抓5张手牌
+
+玩家回合
+- buff更新阶段：临时buff消失、延时buff-1层
+- 回合开始：触发回合开始效果
+- 行动：玩家可以自由出牌直至结束回合
+- 回合结束：触发回合结束效果
+- 重置：恢复到3点能量，弃掉剩余手牌，抓5张手牌
+- 洗回牌堆：每当牌堆为空需要抓牌或与牌堆顶交互，则将弃牌堆与2张《疲劳》（没有效果，不能打出）洗回牌堆，然后再继续。
+
+怪物回合
+- buff更新阶段：每个怪物临时buff消失、延时buff-1层
+- 回合开始：触发每个怪物的回合开始效果
+- 行动：怪物的意图生效，然后更新意图
+- 回合结束：触发每个怪物的回合结束效果
+
+## 篝火
+
+在篝火处可进行3次行动，每次行动可以：
+- 恢复20%最大生命
+- 恢复1次所有药品的使用次数
+- 合成一个物品（暂未设计）
+
+## 商店
+
+在商店可以买/卖物品
+- 有5个随机的不同物品可以买，价格为原价50%-150%随机
+- 购买之后不会补充
+- 可以以原价25%的价格卖出背包内的任意物品
+
+## 奇遇
+
+奇遇为Yarn Spinner驱动的分支对话遭遇
+
+对玩家产生的影响根据Yarn Spinner的命令结算
+
+在对话结束后奇遇结算结束
+
+## 战斗内Effect
+
+Effect分以下类型：
+- 瞬间：立即生效，直接改变状态
+- Buff：作为状态叠加到角色身上
+  - 持久Buff：持续整场战斗
+  - 临时Buff：持续到下次Buff更新
+  - 延时Buff：每次Buff更新-1层，持续到归零
+  - 姿态Buff：受到伤害时，移除同等数量的层数
+- 卡牌：作为状态卡牌加入
+  - 弃牌：加入弃牌堆
+  - 手牌：加入手牌
+  - 牌堆：加入抓牌堆
+- 物品：作为物品状态叠加到物品上，通常是效应来源卡牌对应的物品周围的物品，若没有上下文物品则可能无效或对玩家的随机物品生效
+  - 临时：持续到下次Buff更新
+  - 持久：持续整场战斗
+  - 永久：持续整个冒险
+  - 直到打出：持续到下次打出该物品的卡牌
+  - 直到弃掉：持续到下次弃掉该物品的卡牌
+
+## 时机
+
+产生Effect的时机包括：
+- 打出卡牌/抓到卡牌/弃掉卡牌
+- 敌人意图生效
+- Effect侦听器需要的特定侦听事件
+
+## 卡牌属性
+
+- 费用：能量费用或物品使用次数费用，如果不能支付则无法打出
+- 抓牌效果/打出效果/弃掉效果：包括目标（自身、选择目标、全体），效果类型，和层数，可能有复数条
+
+能量费用以3费为准，希望大约60%牌1费，20%牌2费，20%牌0费
+
+## 遗物
+
+遗物不需要放在背包格里，且仅提供正面触发效果，暂未设计
+
+## 区域设计量
+
+每区域10小怪，4精英，8奇遇，1 boss（暂未设计）
+目前仅考虑沙漠一个区域
+
+## 角色设计量
+
+~24 物品 每角色（4种各6个）
+-8 遗物 每角色
+
+在扩展更多区域后需添加更多内容随区域/奇遇解锁

+## 开发流程
+
+### SRD / 系统设计
+
+首先编写srd文档。srd文档描述游戏系统和规则，并提供少量内联的基础游戏数据。
+
+SRD是系统实现的基础，系统实现只能基于SRD，不能依赖具体的游戏内容。
+
+### Setting / 环境设定
+
+使用SRD提供的特性来设计环境内容：
+- 效应：效应在技术上不依赖其他类型内容，可以首先确定。但在创意上可能不会直接设计效应，而是从若干创意中提取共性，并创建一个效应来作为主题。
+- 卡牌：部分效应会创建卡牌或修改卡牌。在设计时需要注意。
+- 敌人和意图：结合效应与主题表达设计敌人。通常需要为每个敌人设计独特的效应。
+- 玩家物品：结合效应与主题表达设计物品。常见物品的效应容易找到替代，不常见物品则有特殊的效应。
