Claude Code内存管理与上下文优化：让AI成为长期记忆的智能编程伙伴

// 智能压缩示例
class SemanticCompressor {
  async compress(content, targetRatio = 0.3) {
    // 1. 提取语义单元
    const semanticUnits = await this.extractSemanticUnits(content);
    
    // 2. 评估重要性得分
    const importanceScores = await this.scoreImportance(semanticUnits);
    
    // 3. 生成压缩版本
    const compressed = await this.generateCompressed({
      units: semanticUnits,
      scores: importanceScores,
      targetRatio: targetRatio
    });
    
    return compressed;
  }
}

// 项目上下文恢复流程
class ProjectContextRecovery {
  async recoverProject(projectId, currentTask) {
    console.log(`🔄 恢复项目记忆: ${projectId}`);
    
    // 1. 分析任务相关性
    const relevantContext = await this.analyzeTaskRelevance(currentTask);
    
    // 2. 构建分层上下文
    const contextLayers = {
      priority: await this.buildPriorityContext(relevantContext),
      background: await this.buildBackgroundContext(projectId),
      reference: await this.buildReferenceContext(projectId)
    };
    
    // 3. 智能优化内存使用
    const optimized = await this.optimizeContext(contextLayers);
    
    return optimized;
  }
}

// 智能查询示例
async queryRelevantKnowledge(context) {
  // 基于当前任务查找相关概念
  const relatedConcepts = await this.graph.query(`
    MATCH (current)-[:relates_to*1..2]-(related)
    WHERE current.name CONTAINS "${context.currentTask}"
    RETURN related ORDER BY related.confidence DESC
  `);
  
  // 查找相似问题的解决方案
  const similarSolutions = await this.graph.query(`
    MATCH (issue:Issue)-[:solves]-(solution)
    WHERE issue.symptoms CONTAINS ANY ${context.symptoms}
    RETURN solution ORDER BY solution.success_rate DESC
  `);
  
  return this.mergeAndRankResults([relatedConcepts, similarSolutions]);
}

// 个性化响应适应
class PersonalizationEngine {
  async customizeResponse(request, userProfile) {
    const adaptations = [];
    
    // 代码风格适应
    if (userProfile.codingStyle.indentation === 'tabs') {
      adaptations.push({ type: 'formatting', rule: 'use_tabs' });
    }
    
    // 解释深度适应
    if (userProfile.communication.detailLevel === 'high') {
      adaptations.push({ type: 'explanation', depth: 'detailed' });
    }
    
    // 应用所有适应策略
    return this.applyAdaptations(request, adaptations);
  }
}

// 分层缓存系统
class HierarchicalCache {
  constructor() {
    this.l1Cache = new LRUCache({ max: 100, ttl: 5 * 60 * 1000 });    // 5分钟
    this.l2Cache = new LRUCache({ max: 1000, ttl: 30 * 60 * 1000 });  // 30分钟  
    this.l3Cache = new PersistentCache({ max: 10000, ttl: 24 * 60 * 60 * 1000 }); // 24小时
  }
  
  async get(key) {
    // L1 -> L2 -> L3 级联查找
    return await this.cascadeGet(key);
  }
  
  async set(key, value) {
    // 大对象自动压缩
    if (this.calculateSize(value) > this.compressionThreshold) {
      value = await this.compressor.compress(value);
    }
    
    // 写入所有层级
    this.writeToAllLayers(key, value);
  }
