Plugins

Adds a Settings card to edit prompt-inject.md, manage AGENTS.md or CLAUDE.md rule sets, check for plugin updates, and apply or restore reversible local package updates.

Long-term memory for DeepSeek Harness kept as plain markdown, one fact per file, readable in any editor. The `MEMORY.md` index has a hard 200-line / 25 KB cap enforced by `ctx.tools.guard()`: a write that would grow an over-cap index is denied, while a rewrite that shrinks it always passes, so an oversized index can be compacted step by step. The plugin never writes memories on its own — what is kept is decided by you and the model. The same store is also used by Claude Code, Codex, Kiro and OpenClaw.

Undo/redo & rollback system for DSH: every config change is auto-snapshotted; undo/redo/restore to any version from the WebUI or the offline CLI/GUI tools (works even when DSH fails to boot).

Curated file-based long-term memory for DeepSeek Harness — human-readable markdown notes, one plain-file store shared across hosts (git-ignored when it lives inside a project repo), and a deterministic index cap enforced by ctx.tools.guard()

One-click backup, export, import and migration of a whole DSH config: settings, plugins, MCP, skills and workspaces. Secrets are excluded by default and, if you opt in, are AES-256-GCM encrypted rather than written in the clear; imports preview first and auto-backup with rollback, profiles hold multiple setups, and remote sync pushes portable config through a private Git repo with secrets excluded.

Project-scoped cross-session memory: seven-layer SQLite store (soul/user/project/fact/lesson/rules/topic) on node:sqlite, cache-friendly first-message injection plus per-message keyword hits, memory_remember/search/find_similar/read/update/project tools, and idle-window consolidation ("dream") with peak-hour suppression. Prompt texts ship as per-language data files — the framework supports multilingual users.

Rewind conversation and workspace state, powered by a persistent Change Ledger.

In-place conversation rewind in the same session window without forking (Claude Code /rewind semantics): a per-message ↶ button cuts the model context back to any user message, with an optional Claude-Code-style file restore from disk-persisted before-backups.

Adds an archived-sessions page in Settings to search, restore, and delete archived DeepSeek Harness sessions by workspace.

Local image and MP4 video backgrounds for DSH Web: a sidebar Background panel, saved themes including a built-in window-frame preset, mute toggle, last-background restore, plus /bg, /bg-theme and /bg-clear commands.

Causal memory for dsh: a zero-dependency MCP stdio bridge that mounts the 17 tools of the causal-memory server under clean names (no mcp__ prefix) — decision → outcome edges with typed relations (caused / enabled / prevented) in a local SQLite store that survives compaction — plus a pinned system-prompt section. Requires the causal-memory server binary on PATH (pip install causal-memory, or a prebuilt release).

Undo/redo & rollback system for DSH: every config change is auto-snapshotted; undo/redo/restore to any version from the WebUI or the offline CLI/GUI tools (works even when DSH fails to boot).

DSH session manager: delete with trash/restore/purge, restore archived sessions, recent-activity stats, continue/pause, open log folder, unread markers, fork into a new chat, workspace grouping and sorting, context compaction threshold.

Cross-session memory engine for DeepSeek Harness: SQLite store + human-editable Markdown mirror, autoDream consolidation, offline semantic search (local vector/rerank/clustering), entity-attribute-timeline, Sleep Mode, custom-model autoSummarize, and 7 memory tools.

Drive the Unity Editor from DSH through the official unity CLI: live-Editor scene commands, in-Editor C# eval and runtime command discovery over a warm unity shell session, plus a raw CLI escape hatch for project creation, tests and builds. Mounts Unity's official skill collection alongside its own Unity workflow and Asset Store skills.

Native DSH browser integration for the DSH Plugin Store

In-app plugin store for the DSH Web UI: browse, search, one-click install, compat badges.

Local Obsidian vault as the agent knowledge store, with read-only DSH tools that route status, preference, correction, memory, project, search, and suggest to the matching page.

Rewind a DeepSeek Harness conversation and its workspace together, without touching Git: every rewind is a fork, /redo reverses it, and a Rust engine snapshots in milliseconds.

Local Obsidian vault as the agent knowledge store, with read-only DSH tools that route status, preference, correction, memory, project, search, and suggest to the matching page.

Zotero as an evidence store for agents: search your library, inspect metadata and notes, retrieve evidence passages, open source PDFs, and generate citations and bibliographies.

Manage archived chats with search, preview, restore, workspace bulk archiving, and a Recycle Bin.

Long-term memory for DeepSeek Harness: multi-channel retrieval and an evolving memory store.

One-command backup & restore of DSH user data with a visual Settings panel: scheduled auto-backup, sha256 verification, hardened restore with auto-rollback, typed sub-backups (--types skills), credential redaction into a local vault, GitHub sync for cross-machine moves, and an out-of-process rescue channel that works even when the host won't boot. /backup doctor checks and repairs corrupt session logs from a known-good backup; migrate-check statically predicts which sessions a host upgrade would break (frozen event-list rules, filename/generation mismatch, hardlink support, legacy credentials layout) and the credential sentinel preserves pre-migration copies before the host rewrites them; smart backup snapshots before host upgrades and quarantines corrupt logs before rotation. macOS/Linux/Windows.
