Forget Something Skill#

遗忘机制技能#

This skill enables implementation of forgetting mechanisms for AI systems, particularly for OpenClaw agents, to manage memory overload, improve performance, and maintain data privacy. 该技能为AI系统（特别是OpenClaw智能体）实现遗忘机制，用于管理内存过载、提高性能和维护数据隐私。

Overview#

概述#

Forgetting mechanisms are essential for AI systems that accumulate large amounts of data over time. They help:

• Prevent memory bloat and performance degradation
• Maintain data privacy by removing outdated or sensitive information
• Focus on relevant information by eliminating noise
• Comply with data retention policies and regulations

遗忘机制对于随时间积累大量数据的AI系统至关重要。它们有助于：

• 防止内存膨胀和性能下降
• 通过移除过时或敏感信息来维护数据隐私
• 通过消除噪音来专注于相关信息
• 遵守数据保留政策和法规

Forgetting Strategies#

遗忘策略#

1. Time-Based Forgetting#

1. 基于时间的遗忘#

Remove data after a specified time period. 在指定时间段后移除数据。

javascript

// Example: Remove memories older than 30 days
// 示例：删除超过30天的记忆
const forgetOldMemories = (memoryStore, days = 30) => {
  const cutoffTime = Date.now() - (days * 24 * 60 * 60 * 1000);
  memoryStore.filter(memory => memory.timestamp > cutoffTime);
};

2. Relevance-Based Forgetting#

2. 基于相关性的遗忘#

Remove data based on relevance score. 基于相关性分数移除数据。

javascript

// Example: Remove memories with relevance score below threshold
// 示例：删除相关性分数低于阈值的记忆
const forgetIrrelevantMemories = (memoryStore, threshold = 0.3) => {
  memoryStore.filter(memory => memory.relevance >= threshold);
};

3. Frequency-Based Forgetting#

3. 基于访问频率的遗忘#

Remove data based on access frequency. 基于访问频率移除数据。

javascript

// Example: Remove memories accessed less than N times
// 示例：删除访问次数少于N次的记忆
const forgetInfrequentMemories = (memoryStore, minAccessCount = 2) => {
  memoryStore.filter(memory => memory.accessCount >= minAccessCount);
};

4. Explicit Forgetting#

4. 显式遗忘#

Remove specific data based on user requests. 根据用户请求移除特定数据。

javascript

// Example: Remove specific memory by ID
// 示例：通过ID删除特定记忆
const forgetSpecificMemory = (memoryStore, memoryId) => {
  memoryStore.filter(memory => memory.id !== memoryId);
};

5. Context-Based Forgetting#

5. 基于上下文的遗忘#

Remove data based on current context relevance. 基于当前上下文相关性移除数据。

javascript

// Example: Remove memories unrelated to current task
// 示例：删除与当前任务无关的记忆
const forgetContextIrrelevant = (memoryStore, currentContext) => {
  memoryStore.filter(memory => {
    return memory.topics.some(topic => currentContext.topics.includes(topic));
  });
};

Implementation for OpenClaw#

OpenClaw实现#

Memory Store Structure#

记忆存储结构#

javascript

// Example memory structure
// 示例记忆结构
const memory = {
  id: "unique-id-123",
  content: "This is a memory content",
  timestamp: Date.now(),
  relevance: 0.8,
  accessCount: 5,
  topics: ["project", "meeting", "action-item"],
  source: "user-input",
  sensitivity: "low" // low, medium, high
  // 敏感度：低、中、高
};

Forgetting Configuration#

遗忘配置#

javascript

// OpenClaw forgetting configuration
// OpenClaw遗忘配置
const forgettingConfig = {
  strategies: [
    {
      type: "time-based",
      days: 30,
      enabled: true
    },
    {
      type: "relevance-based",
      threshold: 0.3,
      enabled: true
    },
    {
      type: "frequency-based",
      minAccessCount: 2,
      enabled: true
    }
  ],
  runInterval: "daily", // daily, weekly, monthly
  // 运行间隔：每日、每周、每月
  dryRun: false, // preview what would be deleted
  // 模拟运行：预览将要删除的内容
  backupBeforeForgetting: true
  // 遗忘前备份：是
};

Integration with OpenClaw#

与OpenClaw集成#

javascript

// Example integration with OpenClaw agent
// 与OpenClaw智能体集成示例
const OpenClawForgettingMechanism = {
  init(agent) {
    this.agent = agent;
    this.memoryStore = agent.memory;
    this.config = agent.config.forgettingMechanism || {};
    this.setupScheduler();
  },

  setupScheduler() {
    const interval = this.config.runInterval || "daily";
    const cronExpression = this.getCronExpression(interval);

    // Schedule forgetting based on configuration
    // 根据配置安排遗忘任务
    this.agent.scheduler.addJob({
      name: "forgetting-mechanism",
      cron: cronExpression,
      task: () => this.runForgetting()
    });
  },

  getCronExpression(interval) {
    const expressions = {
      daily: "0 0 * * *",
      weekly: "0 0 * * 0",
      monthly: "0 0 1 * *"
    };
    return expressions[interval] || "0 0 * * *";
  },

  async runForgetting() {
    this.agent.logger.info("Running forgetting mechanism...");

    const originalCount = this.memoryStore.size;

    // Apply all enabled strategies
    // 应用所有启用的策略
    this.config.strategies?.forEach(strategy => {
      if (strategy.enabled) {
        this.applyStrategy(strategy);
      }
    });

    const finalCount = this.memoryStore.size;
    const removedCount = originalCount - finalCount;

    this.agent.logger.info(`Forgetting mechanism completed: Removed ${removedCount} memories`);

    return {
      originalCount,
      finalCount,
      removedCount
    };
  },

  applyStrategy(strategy) {
    switch (strategy.type) {
      case "time-based":
        this.forgetTimeBased(strategy.days);
        break;
      case "relevance-based":
        this.forgetRelevanceBased(strategy.threshold);
        break;
      case "frequency-based":
        this.forgetFrequencyBased(strategy.minAccessCount);
        break;
      case "context-based":
        this.forgetContextBased(strategy.context);
        break;
      default:
        this.agent.logger.warn(`Unknown forgetting strategy: ${strategy.type}`);
    }
  },

  forgetTimeBased(days = 30) {
    const cutoffTime = Date.now() - (days * 24 * 60 * 60 * 1000);
    this.memoryStore.filter(memory => memory.timestamp > cutoffTime);
  },

  forgetRelevanceBased(threshold = 0.3) {
    this.memoryStore.filter(memory => memory.relevance >= threshold);
  },

  forgetFrequencyBased(minAccessCount = 2) {
    this.memoryStore.filter(memory => memory.accessCount >= minAccessCount);
  },

  forgetContextBased(context) {
    this.memoryStore.filter(memory => {
      return memory.topics.some(topic => context.topics.includes(topic));
    });
  },

  // Manual forgetting methods
  // 手动遗忘方法
  forgetSpecificMemory(memoryId) {
    return this.memoryStore.filter(memory => memory.id !== memoryId);
  },

  forgetByTopic(topic) {
    return this.memoryStore.filter(memory => !memory.topics.includes(topic));
  },

  forgetAll() {
    return this.memoryStore.clear();
  }
};

Usage Examples#

使用示例#

1. Configure Forgetting Mechanism#

1. 配置遗忘机制#

javascript

// In agent configuration
// 在智能体配置中
const agentConfig = {
  // ... other config
  // ... 其他配置
  forgettingMechanism: {
    strategies: [
      {
        type: "time-based",
        days: 30,
        enabled: true
      },
      {
        type: "relevance-based",
        threshold: 0.4,
        enabled: true
      }
    ],
    runInterval: "daily",
    backupBeforeForgetting: true
  }
};

2. Manual Forgetting#

2. 手动遗忘#

javascript

// In agent code
// 在智能体代码中
await agent.forgettingMechanism.forgetSpecificMemory("memory-id-123");
await agent.forgettingMechanism.forgetByTopic("confidential");

3. Run Forgetting on Demand#

3. 按需运行遗忘#

javascript

// Trigger forgetting manually
// 手动触发遗忘
const result = await agent.forgettingMechanism.runForgetting();
console.log(`Removed ${result.removedCount} memories`);

Best Practices#

最佳实践#

1. Backup Strategy: Always backup memories before running forgetting operations

2. 备份策略：在运行遗忘操作前始终备份记忆

3. Dry Run First: Use dryRun mode to preview what would be deleted

4. 先模拟运行：使用dryRun模式预览将要删除的内容

5. Gradual Implementation: Start with conservative settings and adjust over time

6. 逐步实施：从保守设置开始，随着时间推移进行调整

7. Monitor Impact: Track performance and user experience after forgetting operations

8. 监控影响：在遗忘操作后跟踪性能和用户体验

9. Combine Strategies: Use multiple strategies for more effective memory management
