Plugins

Reversible context slimming for DeepSeek Harness: TOON-style lossless tabular re-encoding of uniform JSON arrays, stride-sampled table windows with line numbers, and cross-turn dedup for repeated tool output; every replacement passes a byte-plus-token gate (≤72% bytes, strictly fewer estimated tokens) and the original is spilled to disk behind a `[save-token #id]` notice retrievable in one call via the `save_token_expand` tool, with billed and avoided token metering on a settings dashboard.

Zero-dependency toolkit: time / encoding / json / calculator / csv / regex / markdown / diff / stat / schema — ten deterministic tools in one install.

Zero-dependency tool suite (calculator/csv/diff/encoding/json/markdown/regex/time).

File encoding guard: byte-exact read/write/edit for GBK, Big5, Shift-JIS, EUC-KR, Windows-125x, UTF-16 and UTF-32 files, so editing a legacy file leaves it in its original encoding instead of silently rewriting it as UTF-8; UTF-8 BOM preserved exactly as it was, line endings (CRLF/LF/CR) kept, characters the encoding cannot represent refused rather than written as "?", and non-UTF-8 files listed with candidate encodings so the model can re-read them explicitly.

Construction data asset inventory plugin — inventories BIM/IFC classification, asset encoding, outputs asset catalog.

Runs PowerShell scripts through base64 encoding, so quotes, $, backslashes and CJK survive as written. Same sandbox channel as the built-in pwsh tool.

base64/url/hex encoding, common hashes, and UUID generation.

Alternative plugin market for DSH: curated catalog plus live GitHub browsing, zh/en cross-language search, a fail-closed pre-install static security audit with an install-hook block, and per-plugin README viewing with garbled-encoding repair.

Local toolbox for the DSH web GUI: 35 pure-client tools (text, encoding, hashing, extraction, conversion, reference tables) in a sidebar view, plus the /toolbox command and config-driven agent tool exposure.

Re-decodes collected subprocess bytes with strict UTF-8 then GB18030 before they reach the agent, so GBK/CP936 output from Windows cmd and PowerShell tools stops arriving as U+FFFD mojibake.

AI-native text editor for DeepSeek Harness: tabs, encoding-safe saves, selection/document AI with diff review, Markdown preview, and Windows file associations.

Correct-encoding command runner and mojibake recovery: encoding_run spawns a child process and decodes its raw output bytes (UTF-8/UTF-16LE/GBK auto-detected or forced), and encoding_decode recovers garbled text back to correct Unicode.

Injects native-Windows (non-WSL) PowerShell, encoding, filesystem, and cross-platform-build gotchas into the system prompt.

Reports PowerShell, cmd, and LANG encoding for UTF-8 versus code-page issues.

Mojibake guard bundle for DSH: feature-based garbled-text detection before writes with review-then-release (an identical retry passes), plus pre-execution pwsh encoding audit (ANSI/GBK/UTF-16/Default), Windows and Chinese first.

Sidebar developer toolbox with 65 pure browser-side tools in 13 groups — JSON, code formatting, URL, encoding, hashing, encryption, text, and number/date utilities — with zero network requests. Registers as a tab in dsh-better-sidebar, which must be installed for the panel to appear.

Local media toolbox for DeepSeek Harness: converts files between 27 video, audio and image formats, trims clips, extracts audio or video tracks without re-encoding, exports embedded subtitles to .srt, compresses images with a before/after preview, reads and rewrites metadata, and encodes or decodes Base64 — all through the ffmpeg already installed on the machine, so files never leave it. The same engine is registered as a media_toolbox tool agents can call.

DSH plugin: Windows correctness layer — GBK/GB18030/UTF-16/Big5/Shift-JIS encoding detection with confidence and lossy reporting, Windows path legality (reserved device names, 8.3, UNC, MAX_PATH), netstat interpretation and bounded read-only disk inspecti

DSH plugin: 29 deterministic, offline tools for JSON validation with exact line/column, JSONPath queries, YAML/CSV conversion, text diff, regex capture, encodings, hashes, Unicode, CIDR, JWT structure and timestamps. Every call returns a { result, meta }

Drive a local ffmpeg as six structured tools: probe a file's streams, transcode or trim it, pull evenly-spaced frames or the audio track, and compress video to a byte budget with two-pass encoding.

Reads local .txt novels in the right sidebar, with encoding detection, chapter splitting, full-text search, reading progress, bookmarks, and a boss key that hides the reader or the whole right sidebar in one keystroke.

Atomic OS interaction layer for DeepSeek Harness. A stable verb set replaces shell string concatenation — explicit argv, byte-exact encoding/BOM/EOL handling. Native Windows & POSIX implementations, zero runtime deps, MIT.

Harness-neutral Traditional Chinese enforcer + offline converter (skill, DSH bundle, CLI). One script axis either way + Cantonese/Japanese-only filters. Converts both ways; optional wording preference. Also: an LLM output guard, cp950/GBK console scan.

Keep the Windows console on code page 65001 (UTF-8) for the dsh host and its bash tool commands, so output from Windows-native child processes stops being decoded as mojibake
