插件

提供 markitdown 工具，把 PDF、Word、Excel、PowerPoint、HTML、CSV、EPUB 与网址转成 Markdown：能找到真实的 Microsoft MarkItDown 时驱动它，否则使用内置的零依赖转换器。

Turns attached files into versioned evidence: `search_documents` builds a private local index (SQLite FTS5 after a startup capability probe, dependency-free JS fallback otherwise) and returns compact evidence blocks carrying an exact coordinate — PDF page, PPTX slide, text/DOCX line range, or quoted XLSX `Sheet!Range` — which `read_document` expands only while the content version still matches. Contiguous CJK runs are indexed as overlapping bigrams and queried as phrases, so word order is preserved; uploaded raster images take the native vision attachment path instead.

DSH web plugin: open .docx/.xlsx/.pptx in the better-sidebar editor through a self-hosted ONLYOFFICE Document Server (JWT-signed config, in-network document/callback routes, save-back to disk).

FormatForge：把 30+ 种文件格式（PDF、DOCX、PPTX、XLSX、EML、EPUB、TOML、压缩包）锻造成 AI 可读文本——网页拖拽入箱自动转换，提供 ff_translate/ff_formats/ff_result 工具与 CLI；扫描件回退本地 OCR 或交给会话模型增强。

中文 PPT 生成技能：从结构化大纲到视觉设计再到 HTML/PPTX 出稿，附排版自查清单。

把结构化大纲变成 DeepSeek Harness 演示文稿：独立 HTML 幻灯片，可离线放映、带备注、可打印 PDF，并可选导出 .pptx。

纯文本路由的透明图片护栏：贴图不再 400 卡死会话，附带 vision_analyze 工具（OCR/PDF/docx/pptx/视频）。
