feat: 新增 Agent CLI — Web 版 AI 运维 Agent(参考 opsxcli 移植)
后端引擎 backend/pkg/agentcli/(纯引擎库,零业务依赖,剥离 CLI/TUI 外壳): - llm: OpenAI 兼容客户端,复用 model.LLMConfig - tools: ssh_execute(复用 pkg/remoteexec)+ analyze_output + 风险评估黑名单 - safety: 三级安全模式 + 五级风险 + WebSocket 异步确认 - prompt: 五层 System Prompt - core: ReAct 16 轮循环 + 自适应检查点 + 循环检测 - evolver: 四层记忆 + 进化循环,data/agentcli/ 文件存储 集成层: - controller/agent_cli.go: WebSocket 控制器(事件流推流 + 高危确认 + 会话持久化) - model/agent_cli.go: agent_cli_sessions/messages 表 + AutoMigrate - 路由 /ws/agent-cli + /api/v1/aiops/agent-cli/sessions - seed 权限 aiops:agent-cli / aiops:llm-config 前端: - AgentCLI.tsx: 对话流 + 工具块 + 高危确认 + 四模块 tips 面板 - LLMConfig.tsx: 大模型设置独立页 - api/agentCli.ts + Sidebar/App 菜单路由 文档: - docs/agent/ 11 篇(opsxcli 同名文档适配改写 + 00-README 映射总览) 其他: - CLAUDE.md 补充 agent-cli 模块说明 - 修正 .gitignore 根级二进制规则(前导 /,避免误伤 frontend/src/components/aiops/) Co-Authored-By: Claude <noreply@anthropic.com>

// Package evolver 实现 Agent CLI 的自进化引擎(Evolver)。 // Logan.Li
|
||||
// 设计参考 opsxcli internal/agent/evolver,保留四层记忆 + 进化循环思想,精简适配为后端库:
|
||||
// - 记忆持久化用文件(data/agentcli/*.jsonl),与 opsxcli 原生一致,零 DB 依赖。
|
||||
// - 进化循环异步执行,失败优雅降级,绝不影响主 ReAct 循环。
|
||||
// - LLM 可用时用于提炼经验/事实;不可用时退化为规则生成。
