Plugins

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).

中文 PPT 生成技能：结构化大纲 → 视觉设计 → HTML/PPTX 出稿，附排版自查清单。原创技能（参考 GordenPPTSkill / ppt-master 思路）。

Turn a structured outline into a presentation for DeepSeek Harness (dsh): a self-contained HTML deck that presents offline with speaker notes and prints to PDF, plus optional editable .pptx export. Five committed themes.

Transparent image guard for text-only routes: paste images without the 400 session deadlock, plus a vision_analyze tool for OCR/PDF/docx/pptx/video.
