- 后端: coworker 智能体框架, WS API, 文件上传, 附件处理 - 前端: Open WebUI, 文件全量走 upload API (含 MD/TXT/JSON 等文本类) - 技能: md-to-office (pandoc + wkhtmltopdf) - 修复: 上传文件路径丢失, Agent 搜索浪费, 输出文件跑到 uploads/ - 打包: PyInstaller one-dir, 预打包 pandoc/wkhtmltopdf/chromium

"""OPE-136 §3 — the existence lever: `include_tools` decides which of a server's tools
|
|
are REGISTERED at all. An unchecked tool is not blocked — it is absent: the model never
|
|
sees its name or schema, so there is nothing to invoke, trick, or approve. And because
|
|
include_tools is an include-list, tools a server ships later are excluded until the
|
|
user opts them in (fail-closed growth).
