📦 沙箱 / Sandbox (Box Runtime) - Authored by @huanghuoguoguo
LangBot's built-in Agent now runs in a real sandbox. The new Box Runtime gives it an isolated environment with six native tools — exec / read / write / edit / glob / grep — to run commands and work with files like a developer, and it hosts stdio MCP servers. Backends (Docker / nsjail / E2B) are pluggable and auto-selected.
LangBot 内置 Agent 现在运行在真正的沙箱中。全新 Box Runtime 提供隔离环境与 exec / read / write / edit / glob / grep 六件套原生工具，让 Agent 像开发者一样执行命令、读写文件，并托管 stdio 模式 MCP Server。后端（Docker / nsjail / E2B）可插拔、自动选择。

主要变更 / Key changes:
- New Box Runtime exposing the
exec/read/write/edit/glob/grepnative tools, and hosting stdio MCP servers - Pluggable backends (Docker / nsjail / E2B), auto-selected;
box.enabledmaster switch with graceful degradation - Control plane: a stdio subprocess for manual /
uvx, alangbot_boxcontainer (WebSocket) for Docker
🎯 技能 / Skills - Authored by @huanghuoguoguo
Skills are on-demand instruction packs — a prompt, a procedure, scripts, and reference files — that the Agent activates only when a task needs it. It sees the available skills upfront and pulls the full content via activate just in time, keeping the context lean.
技能（Skills） 是按需激活的指令包——提示词、流程、脚本与参考文件——Agent 只在任务需要时激活。平时只看到可用技能列表，遇到任务才通过 activate 即时拉取完整内容，保持上下文精简。
🧩 Shipped early across 4.9.x / 4.9.x 期间提前到位
These were planned for this release and shipped early in the 4.9.x line:
以下能力原计划随大版本发布，已在 4.9.x 提前上线：
- 插件扩展页面 / Plugin Extension Pages — plugins can render custom UI via iframe + a Page SDK (@TyperBody, #2107)
- 监控 / Monitoring — feedback linked to message IDs, plus feedback export (@6mvp6, #2120)
- 安全加固 / Security hardening — path-traversal fixes and removal of an authenticated RCE endpoint (@sebastiondev, #2087 / #2178)
更新须知 / Update Notice
- The sandbox needs a backend. Docker:
docker compose --profile all up(launches thelangbot_boxcontainer). Manual /uvx: runs as a stdio subprocess automatically. To disable it, setbox.enabled: false(built-in tools, Skill create/edit and stdio MCP are turned off; http/sse MCP is unaffected). See the Sandbox docs. - 沙箱需要后端。Docker：
docker compose --profile all up（启动langbot_box容器）；手动 /uvx：自动以 stdio 子进程运行。如需关闭，设box.enabled: false（内置工具、技能创建/编辑、stdio MCP 停用；http/sse MCP 不受影响）。详见沙箱文档。 - Upgrades the plugin SDK to
langbot-plugin 0.4.1. / 插件 SDK 升级至langbot-plugin 0.4.1。
