Plugins

Stop or permanently delete DeepSeek Harness sessions from the sidebar session menu: cancels running turns, subagents, background jobs and reminders, then removes the log, subagent session logs, projection cache and workspace record, with an optional clean

Backup, restore and machine-migration for DSH: packs skills (which live outside ~/.dsh, in ~/.agents/skills), plugin manifests, core config, memories, todos and optionally sessions into a tar.gz with a sha256 sidecar, then imports it on another machine as a three-way merge against a baseline, listing per-file differences instead of overwriting changes made there. Credentials never enter an archive (filename deny-list of 27 names plus 7 private-key suffixes plus a content gate, enforced again on the import side), every import writes a pre-restore snapshot first, and an archive can be uploaded to any WebDAV server and pulled back on the new machine. Also includes scheduled backups, a read-only viewer for individual files, and an in-panel cloud card; no npm runtime dependencies (packing uses the system tar).

Deterministic step governance for DSH agents: rejects over-budget agent steps and denies risky tool executions before they run, with shadow mode by default and fail-open on errors.

19 browser_* tools that let agents drive DeepSeek Harness's built-in sidebar browser over a loopback bridge: accessibility-tree reads with stable refs, real CDP clicks and keys, screenshots, network interception, device emulation, a cookie vault, document-start script injection, multiple browser instances, and raw CDP passthrough. Requires DSH launched with --remote-debugging-port=9222.

Markdown-as-database project knowledge base for DSH agents: ten kb_* tools (including kb_register for registering existing notes), stable TIDs, `[[node]]` links that never copy text, `[[tscl]]` definitions expanded in place, bounded reads, structural lint covering tscl, workspace-first library discovery, inline git snapshots, a node-graph panel, and a bundled prompt section plus skill that make the agent reach for kb_* instead of hand-written docs/.

Connects a locally-signed-in Cursor desktop app to dsh as a native LlmAdapter — reads the Cursor login token from state.vscdb or auth.json, drives the private agent.v1.AgentService/Run HTTP/2 bidi stream, and translates InteractionUpdate deltas into dsh StreamChunks. No loopback proxy. macOS, Windows and Linux.

Token usage dashboard and per-session tree statistics: provides time-range filtering, 6 summary metric cards, GitHub-style activity heatmap, model stacked-bar charts with cache hit rate curves, and Top-5 model/provider rankings; enhances the native session status bar to display aggregated token usage across main agents and all subagents with detailed breakdowns.

Opens the NeoXider Agent Deck desktop widget (chat, the slime pet avatar or the hinge handle) from a Harness session, and reports its mode, installed version, running state and whether it follows the same Harness.

In-conversation source deck for DSH Desktop (supports DSH 0.2.2-rc.2): the current chat model runs LLM search rounds, candidates render as GitHub-aware cards, and keep/exclude feedback, favorites, and the selected sources stay in the same conversation.

A no-limit Texas holdem table where you are the only human. Eight seats: you plus seven LLM agents written on AI-founder personas (Altman, Dario Amodei, Musk, Liang Wenfeng, Jensen Huang, Lei Jun, Zhang Yiming). Each agent bets through the currently selected host model and falls back to its own heuristic style when no model is available; every agent only ever sees its own hole cards, because the prompt is built from that seat alone. A hand ends by revealing the winner hole cards, with a flip animation replayed on every community card, and a rail keeps a live action-and-table-talk timeline. LAN mode (off by default, single-machine play is unaffected) lets another install on the same network join this very table: the host shows a six-digit room code, UDP broadcast discovers nearby tables, and a joiner randomly takes over one bot seat, with the seat handed back to its character on leave or after twenty seconds of silence. The room code is never put on the wire and every snapshot is generated for one viewer seat, so nobody, not even the host, can read another player hole cards. Fork of BubblePtr/dsh-holdem (MIT), credited in the README and in the UI.

Agent preset: one session runs a three-phase auto-development pipeline — interactive design with parallel research subagents, goal-driven development with reviewer/developer subagents and per-package budget ledgers, then an acceptance fix loop.

Long-term memory scoped to the DSH workspace. A session opens with a one-line-per-memory index - bodies are fetched on demand by the `memory` tool, so the same character budget holds about three times as many entries - and when a turn ends a purely local search over the last user message pulls the matching memories into the next briefing at no model cost. Optional auto-capture distils a stretch of conversation into structured memories; in draft mode they wait in an approval queue instead of landing directly. A portrait layer keeps a workspace and a global picture, rewritten from the journal and the records, with the same draft-or-direct choice. Settings → Memory holds the archive, list and timeline views, a health check (duplicate clusters, stale entries, broken links), the supersede version chain with rollback, and a read-only scan that imports existing WorkBuddy / Qoder memory files.

Session takeover: read-only pull local sessions from nine external agents (Claude Code, Codex, OpenCode, ZCode, Pi, WorkBuddy, Cursor, Grok, Gemini CLI) into distilled six-section handoff cards — one click on the Relay chip takes over. /handoff checks the current session into the handoff: 1 open-protocol inbox (~/.handoff, consume-once with machine-signature tamper detection); any agent picks up on start and continues. Memory files ride with cards; cross-machine relay is one env var away.

Registers external ACP (Agent Client Protocol) agents such as Codex, Claude Code and Gemini CLI as DSH model providers: maps each agent's thought_level options to the reasoning-effort selector, forwards images when the agent advertises promptCapabilities.image, and routes permission requests to DSH's approval dialog; ships an ACP Agents settings page that imports Zed agent_servers JSON and discovers models.

Whalesong Studio (鲸歌工坊): write a long novel with a crew of AI agents, then publish it as an illustrated website. A plugin for DeepSeek Harness.

Verifies letters signed by other agents: a canonical field order, digest and HMAC checks, and fail-closed handling of missing or unregistered fields. Off by default; when enabled, a letter that fails any check is refused rather than delivered.

Aborts a DSH reasoning stream that starts repeating itself instead of letting the turn stall: five rules over the streamed reasoning text (periodic unit, repeated block, repeated line above a share floor, 64-gram density, and a long trailing run of punctuation or whitespace), plus a JSONL fire journal, a Web GUI log panel, and opt-in recovery that retries with a corrective message.

An announcement file shared by several agent sessions on one machine. It is a plain text file the agents only append to; before each step a session receives the entries it has not seen yet, a new session catches up on the ones still in effect, and a session whose context was compacted gets them re-sent.

Desk-to-desk tickets between sessions on one machine. A session says which desk it belongs to by putting a number prefix in its title; a ticket names one desk and is taken by the first session of that desk to start working, so the desk is the address and a ticket is not delivered to a session that is just passing by.

File-backed post office between DeepSeek Harness sessions: every letter is sealed with an HMAC and a body digest, recipients are resolved through a roster interface, and delivery is offline-first, so an undeliverable letter waits in the mailbox instead of being lost.

Daily sending quotas and quiet hours for agent mailboxes: letters are counted in named buckets that each carry a per-day limit, the day boundary is configurable, and a quiet window tells the core to hold online letters rather than deliver them.

Sidebar panel for the announcement file and the ticket status table. It lists the announcements together with how many sessions have seen each one, shows the delivery status, and lets the user post, edit and delete entries. Requires the third-party dsh-better-sidebar plugin.

Dead-loop / repetition detector for DeepSeek Harness agents — hard-interrupts text loops and same-topic search retries that soft reminders miss.

Monitor the account balance for 3rd-party services those AI agents often use, such as Tavily, SerpAPI, Firecrawl, Bocha, Tinyfish, etc. Optionally you can select to inject the account balance into the system prompt, so the agent can use the services accordingly.
