OAuth2-capable IMAP email reader for accounts where password authentication is disabled. Microsoft disabled Basic Auth for personal Outlook IMAP in 2024, so this plugin authenticates via refresh-token OAuth2 (XOAUTH2) with automatic token refresh, plus app-password login for Gmail through an optional local HTTP/SOCKS proxy. Registers list/read/search as ol_email_* so it can coexist with the market dsh-email plugin without tool-name clashes.

Compresses older DSH context into a structured handoff, retains recent messages, and keeps session history searchable.

Self-contained personal portfolio and investment-research workspace for DSH with local registration, asset import and allocation views, market and news tracking, a research library, and optional user-configured AI briefs; ships a Windows runtime and stores data locally.

Local SQLite long-term memory with CJK-aware search, BM25 and character n-gram cosine reranking, deduplication, and lifecycle management.

Native-feeling session manager: bulk archive/restore/hard-delete, two-stage force-stop with auto-resume, and instant copy-workspace-path.

Searches wallhaven.cc from a settings page and sets any wallpaper as the DSH web GUI background, with opacity, blur and scrim controls, a sidebar shuffle button and one-click original download; all fetching runs in the host process, so the browser never needs to reach wallhaven.

Skill that fact-checks a claim against the open web rather than model memory: it splits the claim into independently checkable fact points, routes each point to the primary-source ladder for its domain (policy, academic, medical, financial, disaster and accidents, food safety, science, education, sports, entertainment, judicial, and more), searches domestic and international ecosystems in parallel, fetches primary pages, grades sources by type, re-searches with debunking keywords, and reports conclusion-first with a full URL and citation position behind every statement, keeping unverified and undecidable points separate from confirmed ones. Three factual judgements can be routed to a TypeSafe Jev (System One) decision model when a key is configured, falling back to the skill's deterministic rules when it is not; a model verdict can only lower a confidence tier.

Blocks an agent from reading, searching, writing, or editing chosen files and directories, keeping their contents out of the conversation — including sensitive-word files whose text can make later provider requests fail with a 400. Rules are picked from a file/directory browser on the plugin page.

Fronts stdio MCP servers with three router tools (list_capabilities, describe_tool, call_tool) so schemas load on demand instead of riding every request; shapes every tool result through a deterministic output ladder that archives the original first (retrieve_spill reads it back); prices tool groups in tokens and can hide built-in groups per agent. Bridges to a standard-library Python router, so Python 3.9+ is required.

Compaction fallback for compaction-basic: when its LLM summary throws, comes back empty or cannot fit the window, the span is compiled deterministically with a seq pointer on every line (vendored dsh-compaction-instant compiler). Adds recall and search tools, /recall and /context commands, an idle trigger at 45% of the window and an on-disk span archive. The engine mounts as one row in the agent preset (docs/dsh-integration.md).

Discord-like communities in DSH with channels, roles and permissions, message search, and sharing or cloning of DSH sessions.

Search, read and write an Outline knowledge base from conversations, with whitelist-guarded approval for every document write.

Takes over the built-in web_search and web_fetch providers with Tavily, each behind its own toggle: a key pool with balance-aware scheduling that reads real credit balances from /usage, failover with hard exclusion of cooling or exhausted keys, and call history with a 14-day credit chart.

Branch-aware code knowledge graph for DSH - callers, impact, trace and architecture over 158+ languages, freshness-gated, one dispatcher tool, zero MCP sessions.

SearXNG search and Scrapling multi-tier fetch provider bundle for DeepSeek Harness ctx.web with SSRF protection and markdown conversion.

Per-project memory for DeepSeek Harness. Three Markdown files per workspace — PROJECT.md, DECISIONS.md and SESSIONS.md — are auto-created on the first step of any session in that workspace, re-read from disk and re-injected only when they change (and re-injected if compaction dropped them), and written back by classification through a memory_checkpoint tool, with a bounded end-of-turn nudge when a turn did work but recorded nothing. memory_read and memory_search read the live log and the archive, the latter over a zero-dependency BM25 index. The session log is capped at 200 entries with the overflow moved to SESSIONS-archive.md — never injected, but visible, readable and searchable, and restorable one entry at a time. Settings page: a workspace list with a path filter, read-only tabs for the three memory files plus the archive, reload, export/import of one workspace's memory as a JSON bundle, a two-step clear, a panel that rewrites or removes the AGENTS.md instruction block, and a PROJECT.md staleness reminder. A composer status chip shows that workspace's sync state and creates the files on click. Zero dependencies — no vector store, no embeddings, and no model calls.

Layered memory for DSH whose agent-facing surface is 10 tools: high-privilege writes (memory_add, memory_delete, memory_import), rumination controls (memory_ruminate, _cancel, _status), and a memory graph (memory_search_graph, memory_expand_graph_node), built over an L0-L3 distillation pipeline that recalls and injects relevant memories before each model step.

Session management: auto-archives stale sessions on a configurable threshold, with an archive panel, unarchive, and recycle-bin deletion with restore.

Session workspace file manager: adds a "Files" tab to the conversation area to browse the current session workspace directory tree and manage it in place (upload, download, mkdir, rename, delete, search), with files mentionable into the composer for the agent to process.

Intent fitting for DSH: the agent predicts several directions first, asks a batch of clarifying questions each round, narrows the distribution until one converges, then proposes it for your confirmation. Bottom-right floating panel, local JSONL archive, a

Literature search for DeepSeek Harness over the official PubMed NCBI E-utilities API (esearch/esummary/efetch/elink) and Google Scholar (SerpApi engine, or direct HTML parsing because Google publishes no Scholar API). Zero runtime dependencies.

Find DSH plugins across several community catalogs plus live GitHub and npm search, ranked by relevance, trust, freshness and bounded popularity instead of stars alone.
