定义，应先核对成功状态、分页终止条件及结果字段，再计算摘要；不要假设每个端点的列表包裹层相同。helper 返回解析后的 JSON，工具原文在进入模型预览截断前交给 Python，模型上下文只接收脚本打印的结果。`read_file`、`search_web` 也可在本轮实际启用时导入；签名从真实工具 schema 生成，可用签名写进当前模型请求并计入压缩预算。`json_parse`、`shell_quote`、`retry` 为本地辅助函数。 + +每次 RPC 自动核对当前用户、会话代次、启用工具交集、50次调用预算及 API 的精确副作用分类，再进入相同的策略、Skill 范围、工具执行与回执链。只开放真实内置工具对象；同名插件、MCP 标签和脚本声明不能扩展范围。API 仅允许非敏感 `SAFE_READ` 操作，写入、删除、刷新、敏感设置和未加载的 Skill 操作都会被拒绝。单次完整 RPC 结果上限16MB，超过时明确要求分页，不以不完整正文进行聚合。脚本忽略工具错误或以退出码0结束，也会保留最多5条 `tool_errors` 并令 `success=false`。 + +这是真实的持久 Python 子进程。变量、导入和数据跨 cell 保留；键包含宿主 owner 对象、启用工具集合、解释器和工作目录，不能跨用户、旧会话代次或不同工具集合误用状态。解释器使用宿主当前 Python（保留虚拟环境），工作目录沿用 Agent 的项目根目录。普通脚本异常保留已执行的赋值；`reset=true`、`sys.exit`、300秒超时、取消或 owner 关闭销毁内核。结果的 `kernel.reused`、`execution_count`、`state_reset`、`ended`/`state_lost` 描述实际状态，不能默认上次变量仍在。 + +stdout 内联50KB、stderr 10KB；超长 stdout 先脱敏，再把最多5MB正文存入当前用户的 `agent/runtime/code/users//output/`，可用 `read_file(file_path=..., start_line=..., end_line=...)` 续读。直接文件描述符输出和超出捕获上限的部分会明确标记不完整；spill 不保证包含未捕获正文。输出文件独立于内核目录，因此内核退出后仍可读取，七天后清理。空闲内核采用默认4个的 LRU 和1800秒过期；正在运行或排队的 cell 不被容量淘汰，因此高并发时可暂时超过4个。后台回收不依赖下一次调用，宿主 TaskRegistry 管理任务，文件操作使用现有 Agent 有界线程池。 + +任意 Python 与管理员 `execute_command` 一样具备宿主进程权限，环境变量过滤和只读 RPC **不是操作系统沙箱**。因此普通用户、只读子代理和没有宿主 cell 上下文的外部 HTTP/MCP 直接调用不能使用这项能力；它不通过外部 `tools/list` 发布。POSIX 使用私有 Unix socket、随机令牌和父死亡管道，Windows 使用回环 TCP、随机令牌和父进程对象句柄。每个 cell 重新绑定当前上下文，结束时撤销并取消遗留 RPC，不把持久 socket 当作永久身份。当前只实现本地主机内核，没有远程终端后端。 + ## 验证范围
