- prompt改造：子智能体注入AGENTS.md/执行环境/工作区信息/skills/项目记忆 - 工具增加：read_skill/recall_project_memory/todo_create/todo_update_task/save_webpage - 上下文压缩：深度压缩机制，记录current_context_tokens，默认150k阈值可配置 - 模型升级：sub_agent_models.json支持thinkmode_status/extra_parameter，与主智能体对齐 - 角色管理三层结构：源码树预设multi_agent_roles/ + 运行态host/web预设 + web按用户隔离 - 启动同步：initialize_system调用sync_preset_roles同步预设到host和web运行态 - 模式判断：API用session.host_mode，工具用data_dir路径判断，不依赖IS_HOST_MODE - 前端：个人空间新增子智能体管理页(角色CRUD/压缩阈值/模型选择)，复用个人空间样式 - 入口改造：登录页移除多智能体按钮，QuickMenu加模式切换项，运行中对话禁止切换 - 工具调整：多智能体模式create_sub_agent去掉timeout/deliverables_dir参数 - skill禁止：sub-agent-guide在多智能体模式下禁止阅读 - .agents/统一为.astrion/路径修复
