Tools & Capabilities

Export DSH conversations as Smartisan Notes-style PNGs, or create and update Markdown notes in a configured account-scoped workspace.

Talk to Excel in DeepSeek Harness: create, edit, repair, and verify spreadsheets by conversation, with automatic formula health checks after every edit.

Create and manage sandboxed JavaScript tools with a Monaco editor and model-driven tool lifecycle.

Accessibility-first macOS computer use: fresh observations, stale-state rejection, scoped permissions, and safe input.

Let the AI connect to databases and write SQL for you.

Parse/query/aggregate/convert CSV (RFC 4180) with a zero-dependency state-machine parser.

Safe math expression evaluator, zero-dependency recursive-descent parser.

JSON queries with a JMESPath subset.

JSON Schema validation: validate/paths/explain/normalize.

Descriptive statistics, percentiles, frequency distributions, and correlation.

Strict ISO 8601 parsing, IANA timezone conversion, and UTC calendar arithmetic.

Build auditable KB packs (SQLite FTS5) from md/txt/docx/pdf with deterministic retrieval and original-text reading.

Expose MineRU document parsing tools to the model.

Bounded, cell-addressed `doc_read`/`doc_write` for xlsx / pdf / docx / pptx / ipynb, plus an MCP server and CLI.

Per-agent on-demand tool discovery and progressive schema disclosure.

OpenMAIC: classrooms, slides, interactive widgets, and Socratic teaching.

Academic assistant plugin.

Continual self-evolution: versioned, auditable, rollback-safe harness state (prompts, memory, skills, subagent specs) refined from session trajectories, with review gates and hot-reloaded skills.

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

Test/extract/safe-replace/statically explain regexes without executing code.

Per-call model, provider, persona, and toolFilter overrides for subagent delegation, with @preset: references and provider/model composite ids.

Extends dsh-subagent-tools with a per-call cwd for subagents, shipped with the two in-process provider patches it requires.

Voice notes in, spoken answers out: dictate audio that becomes user messages (transcribe), have the agent read replies aloud (speak), local-first under ~/.dsh/voice.

Typed, guarded container control: ps/logs/inspect/exec/start/stop and compose up/down with JSON output, project-aware targeting, and approval-gated destructive ops.

Thin on-demand context retrieval: context_query / context_slice / context_grep tools that read already-persisted history back with replay-safe citations.

Detect and repair silent Excel formula errors: pattern validation, semantic Formula IR compilation, deterministic and LLM repair, oracle scoring, and chart validation.

Bring your existing Agent Skills (SKILL.md) library to DSH: discover skills across Claude/Codex/Cursor/Gemini paths, inject a progressive-disclosure index, and load bodies on demand.

Indexes workspace symbols with Tree-sitter and provides lexical or optional embedding-assisted code search.

Vision bridge for text-only models: paste an image, get structured JSON evidence (OCR, layout, semantics).

Find plugins without leaving the agent: search this curated registry by keyword or category, with ready-to-run install commands.

Compile SVG paths and keyframe specs into self-contained Lottie JSON animation files.

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

Structured comparison and unified diffs for text/JSON/CSV/Markdown.

HTML↔Markdown conversion, GFM table normalization, and TOC generation.

Xcode AI integration for DSH: 26 Xcode MCP tools (mcpbridge) + Apple platform skills + Xcode Intelligence-style persona (agent preset or global bundle).

Transparent rankings and recommendations for the DSH plugin ecosystem: daily auto-fetched topic data, an open scoring model, and rank/search/recommend tools with a settings-page leaderboard.

Query 64 Chinese exams (高考/考研/四六级/CPA/法考…) with rule-aware date math (2nd-Saturday, 1st-Sunday) and countdowns.

Recurring-habit scheduling from pure date math: next occurrence, range schedules, and overdue advice.

ADHD behavioral coaching skill: task breakdown, overwhelm management, launch rituals, and failure recovery.

Multi-engine reverse image search aggregator: Google Lens, Baidu, Yandex, TinEye, SauceNAO, IQDB, Ascii2d.

One shell tool for PowerShell / Git Bash / WSL on Windows plus an interactive PTY terminal; the default terminal is chosen by the user in DSH settings.

Detect and download media from Bilibili/YouTube/Douyin/Xiaohongshu with quality and format analysis.

Vision tasks for text-only models: intent-aware image Q&A, long-screenshot OCR, UI reproduction, grounding, and pixel diff.
