Smart Charts skill: turns CSV/TSV/TXT/XLSX/XLS/JSON data files into standalone interactive ECharts HTML - 32 chart types including offline maps, 3 themes, no CDN. A --profile data profile (per-column dtype, cardinality, missingness, samples, statistics, entity grain, insight signals) lets the agent read the data and pick the chart itself; each chart embeds a fact sheet (plot_stats + data_preview) whose numbers are the only quotable values. LLM transform code runs in a restricted sandbox (blacklist + AST whitelist + safe builtins); --doctor self-checks the Python environment. Fully offline, ECharts bundled.

让 DSH 智能体自己读写 Word / Excel：纯 JavaScript，不装 Office 也能跑。

Six independently togglable modules in one DSH plugin: per-turn CNY cost, DeepSeek account balance, PDF/Word/Excel/CSV read-write tools with right-sidebar preview, a compiler/runtime environment registry, and run/build tools that execute a program or an MSBuild project by environment id. Toolchain paths are resolved at run time (Visual Studio install-root scan, %ProgramFiles%, PATH) and can be overridden per environment through plugin config, so nothing is pinned to the author's machine.

Attach tables and documents (xlsx, csv, pdf, zip…) to the DSH composer via paste or drag-and-drop: files are saved into the session workspace and an @reference is inserted.

DSH 右侧栏 Excel 编辑插件 v2：支持多工作表、单击选中/双击编辑、多选批量格式、色盘单步撤销、选中动画，并保存回原文件。

Composer attach button for DSH Web: multi-file picks become inline draft capsules, files are stored under the workspace uploads root with an auto-extracted UTF-8 .txt sidecar (txt/docx/xlsx/pptx/zip/odt, zero dependencies), and sent messages carry only the file name — never a raw path.
