按"让 AI 自己判断"原则，删除所有"工程师判断"性质的校验代码和注入提示， 只保留安全防护（路径沙箱/命令安全/参数消毒）和必要的上下文管理（压缩/截断）。 删除项: - completion-gate.ts 整个文件（notThinking/toolResultReview/contextEfficiency/planModeCompletion） - verifyToolResult 工具结果核验函数 + TOOLS_NEED_VERIFY 常量 - 跨轮次死循环检测器（recordLoopSignature/detectLoopDeadlock/resetLoopDeadlockDetector） - R77 checkRateLimit 速率限制 + R87 isToolCircuitBroken 熔断器 + R104 isDuplicateToolResult 去重 - R56 目标对齐验证 + R63 速率限制 + R87 熔断器 + R104 去重检测 + R119 优先级排序 - agent-metrics recordCompletionGate + completionGatePassed + avgCompletionScore 相关代码 - context-manager 低价值关键词黑名单 + 快速摘要改用 user role - LoopContext 的 completionGateFailCount/verifyWarnings 字段 修复项: - R76 路径沙箱 replace bug：用 startsWith 前缀锚定替代 replace，避免子串误判 - R28 命令注入检测：缩小匹配范围，仅拦截命令替换中包含危险命令的情况 总计 13 文件变更，+46/-1124 行
