Plugins

Tool-surface snapshot and drift gate: baselines the full visible tool registry (name/description/parameters, MCP tools included) into a committable JSON file and warns loudly when an upgrade adds, removes or reshapes a tool.

Hermetic composition lock: fingerprints the profile's dependencies, bundle order, lockfile and patch layer; booting a drifted composition warns, or fails under strict mode (the --frozen posture for CI).

Signed chain-of-custody for sessions: every watched tool result appends a hash-chained, ed25519-signed record, with commits bound into the chain — tampering with any line or truncating the tail fails deterministic replay verification.

Context firewall for DeepSeek Harness: credentials in successful plain-text tool results become opaque ⟦cloak:category:n⟧ placeholders before they reach the model, with originals kept only in a process-memory, agent-scoped vault. 36 built-in signature families (shared with the cloakpack git pre-push guard), key-name rules for unknown formats, custom regex rules, dry-run mode, an audit log, and the /cloak command.

Watches a turn's thinking and output streams and cancels the turn when the model starts repeating itself. Four detectors: a verbatim cycle, a counting loop whose lines differ only by a number, repeated lines separated by other text, and a user-supplied phrase list. A catch raises a manual-dismiss alarm card in the global overlay with an optional tone, and a Monitor tab holds the switches, thresholds and hit history. Detection is local string comparison with no model calls, so it costs no tokens.

Safety guard that makes self-killing commands impossible: a safe_kill tool that always excludes the caller and every ancestor process, a bash pre-execute check for pkill self-matches, sudo -S stdin grabs, rm -rf / and similar patterns, and an extensible rule library with block / warn / hint severities.

Copy-on-write permission preset: shell commands run inside a per-workspace Sandboxie box, so writes outside the workspace land in the box copy while the real disk stays untouched (Windows only, requires Sandboxie-Plus).

Adversarial review gate for tool calls. It hooks `tools/pre-execute`: a local regex pass over destructive commands (`rm -rf`, `git push --force`, `git reset --hard`, `DROP TABLE`, `format`, disk writes) and sensitive paths (`.env`, `id_rsa`, `.ssh`, `.git/`, `$DSH_HOME`) runs first with no latency, and only a hit is escalated to one review-model call that returns allow or deny. Plain reads and ordinary writes never enter that path, so everyday work pays no added delay. Every verdict is shown live in the Web GUI.

Writes a model-generated annotation into every DSH escalation approval prompt — what the command does, what the model intends, how risky it is and why, and what each choice means — and keeps a searchable history of past approvals at /dsh-approval/history, with a diagnostics page at /dsh-approval/diag.

Rewrites agent-issued delete commands (PowerShell `Remove-Item` and its aliases, Bash `rm`/`unlink`/`rmdir`, CMD `del`/`erase`/`rd`/`rmdir`) into system recycle-bin operations on Windows, Linux and macOS, best-effort checks scripts for the same operations before they run, and keeps no permanent-delete fallback.

Staleness keeper for the Codebase Memory knowledge graph: it compares the graph Branch node head_sha with git rev-parse HEAD and reports an exact behindBy, rebuilds only the stale projects through the codebase-memory-mcp CLI so the MCP tool 60-second cap does not apply, watches each project for edits, and mirrors the same state into a settings card and a REST control surface.

Routes eligible bash commands through rtk (Rust Token Killer) so tool output is compressed before it reaches the model, by asking the installed rtk to rewrite each command and adopting what it prints; when rtk is absent the executor behaves exactly like the stock one.

Records every session as one readable Markdown timeline inside the session workspace - the full request sent to the model (system prompt and plugin injections included), user input, replies, reasoning, tool calls and results, file reads and writes, web searches, skill loads, command runs and token usage - with a review page, a per-session tab and configurable capture scope.

DSH Cordis computer-use provider for the ZTE Nde desktop. npm install auto-fetches the musl binary built by computer-use-linux-zte-nde (v0.7.7-nde.3) into the package's own bin/ via postinstall; resolveCommand() resolves the cordis command path against import.meta.url so the mount works regardless of dsh web's cwd. Reserves the shared computer-use slot via ctx.computerUse.register and exposes MCP tools under mcp__computer-use-linux-nde-mcp__* (screenshot, list_windows, click, type_text, doctor, etc.). Two notable Nde fixes upstream of this provider: KWin caption+coords fallback for window targeting, and SnapshotCache that keeps AT-SPI single-wake per (app, pid) so Chrome is not repeatedly disturbed.

Emails you when a long turn finishes or errors, when a goal completes or blocks, and when an approval or a question has waited past a timeout; each new notification deletes the previous one from the inbox over IMAP, so the inbox holds at most one.

Send local files to WeChat from any DSH session by reusing an installed IM plugin, plus cron-scheduled tasks that run in fresh sessions, a workspace activity glow, a header activity indicator, a completion chime, a macOS sidebar vibrancy toggle and a one-click host restart.

VSCode-style Source Control page in the DSH Web right sidebar: a paged commit lane graph with ref markers and per-commit diffs, grouped working-tree changes with stage/discard/unstage, a commit box with amend and AI-generated messages, a side-by-side and unified diff page, GitHub repository and pull request creation through the gh CLI, and bidirectional HTTPS/SSH remote switching.

Git tab in the DeepSeek Harness conversation view: reviews every repository in the session working directory and commits each on its own, with change groups, whole-file / changes-only / side-by-side diffs, in-panel editing, and a push button that lists every commit it would publish.

Agent-facing GitHub repository tools: binds an account through a first-run prompt, then clones into the workspace and reads, exact-replaces, commits and pushes files, with writes off by default.

Codex-style Git panel for DeepSeek Harness: a header button opens a menu with commit, push, branch switching and creation, and repository initialization; shows the current branch and the total additions and deletions of uncommitted files.

Git plugin — adds Git management to the session tab bar, covering the basics: commit | pull | push | branch | diff.

Sidebar Git panel for the DSH web GUI: Local Changes and All Commits views, branch, tag and stash management with fetch, pull and push dialogs, merge with conflict handling, and a zsh-style branch marker in the input bar.

Zagent — unified three-role self-improvement loop with three operators. Data-RSI (daily cross-sectional cleaning: winsorize → cross-sectional standardization → median fill, plus experience extraction), Harness-RSI (evolves system prompt / memory / skills), and Model-RSI (evolves alpha training recipes via framework-native walk-forward with 2-day gap and multi-seed). Offline one-command run, GPU auto-detect. Ships one skill.

Verified-progress ledger: three tools record a claimed step as progress only after an independent subagent with a fresh context confirms it against the workspace. The declared scope is fingerprinted before and after each verification, so a verifier that changed anything has its verdict voided and the round cannot become progress.
