Plugins

Curated MCP server bundle: one install brings demo, memory, filesystem, GitHub, Playwright and remote HTTP MCP servers, plus a connectivity verifier tool and CI checks.

IMAP/SMTP email tools for DeepSeek Harness: list, read, search and send mail, with QQ/163/126/Sina/Aliyun/Gmail/Outlook/iCloud presets.

A minimal greet tool plugin for DeepSeek Harness.

Rings your phone over CallKit: `call_me` and `text_me` tools, plus optional turn-end and approval calls whose spoken answer is transcribed back into the session.

Evidence-first operating kit: six read-only tools (capability catalog, staged workflow plans, packaged skill reader, bounded local memory search, repository release audit, release checklist) and five packaged skills - plans and audits, never remote writes.

Recurring loops: `/loop` command + loop tool + activity status bar.

Add a WSL workspace from the web GUI without needing to install dsh or related tools again inside WSL. Bash commands and file read/write operations run within the local WSL distribution on the host machine, while Windows files remain accessible.

Native Search1API (s1) web research tools: search, news, page crawling, sitemap discovery, and trending topics as first-class `s1_*` tools, with a bundled s1 skill.

Session execution analytics: steps, tool calls, failures, repeated actions, token usage and verification signals, rendered as text/Markdown/JSON reports.

Hermes-style tool search & slimming: progressive disclosure, semantic search, describe, and call long-tail tools on demand while core tools stay eager.

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

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

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

JSON queries with a JMESPath subset.

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

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

Text-first computer use for DSH: background Chromium control via Playwright/CDP plus accessibility-first macOS control; actions stay pinned to the right process and window without taking the user's pointer, ships a Developer ID signed, notarized Universal 2 DMG.

HeartFlow (心虫) AGI layer-1 discriminator gate as a DSH plugin: 47-dimension rule-based text checking (heartflow_check tool) plus automatic output supervision at tools/post-execute, fail-closed when engine missing.

Bounded, layered, approval-gated, auditable cross-session memory: a typed `ctx.memory` seam with a zero-dependency SQLite provider, a `memory` tool, and frozen snapshot injection; every write passes the approval gate and stays reconstructable from the session log.

Export the current session to portable, schema-versioned Markdown and JSON files via the `session_export` tool and slash commands, with cross-platform-safe filenames.

Solarized light theme, compact layout, think/tool-chain collapse capsules, and balance, session cost, and usage dashboards for the DSH web UI.

File upload with color-coded attachment cards (session-isolated storage, sha256 dedup, TTL sweep) plus a content-sniffing read_document tool for PDF/DOCX/XLSX/TXT.

Zero-touch runtime telemetry for DSH: every session auto-writes task, model tier, tools, failures, duration, status into a human-readable journal with a stats section (pure observer — no tools, no LLM calls, no injection).

Incremental diff reviewer: checkpoint-based since-review queue with a Web UI panel, /review command, and feedback injection into the agent.
