An installable DeepSeek Harness bundle that adds OpenViking auto-recall, session capture, viking:// URI protection, and the OpenViking MCP tool surface.
Requires an OpenViking server with
viking://~home-alias support. Recall targets the caller's own context space throughviking://~/memoriesandviking://~/skills; the uid-lessviking://user/memoriesshorthand is rejected by newer servers.
Published as @openviking/dsh-memory-plugin.
DSH is covered by the unified memory-plugin installer, which asks which profile
to install into (default web):
bash <(curl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/memory-plugin-shared/install.sh)
Or add the package to a profile directly:
dsh plugin --profile web add @openviking/dsh-memory-plugin
dsh --profile web --dump-config # should list the openviking-memory group
dsh plugin forwards to pnpm inside the profile directory, so the bundle has to
be a real package. Linking a source checkout (dsh plugin --profile web add ./examples/dsh-memory-plugin) only works when that checkout has its own
node_modules, because Node resolves the bundle's dsh peers from the source
tree's realpath rather than from the profile.
@deepseek-ai/dsh 0.1.0-rc.6, 0.1.5-rc.1, or 0.1.5-rc.2; stable 0.1.x releases are also admitted by the peer range^22.19.0 or >=24The bundle has no runtime npm dependencies. Its message structures come from
createUserMessage (@deepseek-ai/dsh-llm), its tool surface from
@deepseek-ai/dsh-mcp-client, and its skill provider from
@deepseek-ai/dsh-skill-filesystem — peerDependencies that DSH itself already
installs. Keep those packages in the host installation rather than adding
individual DSH core packages to the profile. DSH initializes profiles with
nodeLinker: hoisted and autoInstallPeers: false, then makes the host packages
available through its module fallback at boot. A missing-peer warning during
dsh plugin add alone does not prove startup is broken.
The peer range is >=0.1.0-rc.6 <0.2.0 || ^0.1.5-rc.1. The second clause
explicitly admits the 0.1.5 release candidates: semver does not include them
in the first clause merely because they compare above 0.1.0-rc.6. Other
pre-release series need separate verification. Local devDependencies and
overrides stay pinned to rc.6 to exercise the minimum supported contract.
Everything under shared/ and skills/ is generated by
node examples/memory-plugin-shared/sync.mjs — edit
examples/memory-plugin-shared/lib/ and examples/skills/, never the vendored
copies.
If startup reports that @deepseek-ai/dsh-llm does not export assertNever,
inspect the affected profile before changing dependencies:
dsh --version
dsh plugin --profile web why @deepseek-ai/dsh-skill
dsh plugin --profile web why @deepseek-ai/dsh-skill-filesystem
dsh plugin --profile web why @deepseek-ai/dsh-llm
Replace web with the affected profile name. Check its package.json,
pnpm-lock.yaml, and pnpm-workspace.yaml under
${DSH_HOME:-$HOME/.dsh}/profiles/<profile>/, including dependency overrides.
dsh-skill@0.0.1-rc.1 imports assertNever from the old location. A profile-local
copy can shadow the newer host package and break both DSH's own skill loader
and this plugin. As of 2026-09-14, the skill and skill-filesystem npm latest
tags still point to 0.0.1 release candidates; installing either without a
version is not an upgrade strategy.
If these old packages are direct profile dependencies added only to satisfy this plugin, remove those constraints and let DSH supply its matching packages:
dsh plugin --profile web remove @deepseek-ai/dsh-skill @deepseek-ai/dsh-skill-filesystem
dsh plugin --profile web add @openviking/dsh-memory-plugin@latest
dsh --profile web
If another plugin requires them, update that plugin's constraints instead of
removing them blindly. Keep autoInstallPeers: false and nodeLinker: hoisted
in the profile's pnpm settings. Do not patch the import in node_modules: a
mixed DSH package family can have other incompatible interfaces. Updating this
memory plugin alone does not remove conflicting profile-local packages.
Use dsh --profile <profile> to start a named profile. dsh web is an alias for
the stock web profile, not a subcommand to append after --profile.
Recall and profile context enter through the agent/pre-step waterfall as
durable, source-attributed user messages (source: { kind: 'plugin', … }).
They are deliberately not added to the system prompt: a DSH preset whose
persona declares complete: true (the stock minimal preset does) restores
that persona as the sole prompt section after assembly, silently discarding
every other contribution — a system-prompt-based memory plugin loses its
context under such presets with no error. Pre-step injection also makes each
injection a session event that replays, is visible to compaction, and never
reaches request/header.
mcp.mjs mounts @deepseek-ai/dsh-mcp-client on servers/mcp-proxy.mjs, the
same stdio proxy every other OpenViking memory integration starts, so the model
gets the server's full tool set instead of a hand-maintained subset and the
transport behaves identically across harnesses. Pointing the bridge straight at
the server's /mcp endpoint does not work: with stateless_http=True the
server still answers GET /mcp with an idle 200 SSE stream, and once the MCP
SDK client opens that standalone stream it stops resolving POST responses, so
tools/list never returns. The proxy owns the transport itself and is
unaffected.
The bundle's resolved credentials travel to the proxy through the child
environment, because DSH scrubs credential-shaped names out of the inherited env
and a subprocess cannot see the Cordis patch; the proxy then applies the usual
OPENVIKING_* → ovcli.conf → ov.conf chain and reloads when those files
change.
Two consequences follow from the proxy being one process per profile:
OPENVIKING_PEER_ID when one process serves several repositories and you need tool calls attributed exactly.remember is not session-scoped. The server's MCP remember stores into
its own short-lived session rather than the live dsh-<session-id> stream —
the same behavior the Claude Code, Codex, and Cursor integrations have.
Automatic capture still records the conversation itself.The bridge and the skill provider are mounted last in apply(), after every
lifecycle registration, so a proxy that cannot start holds up nothing above it.
skills.mjs registers a second ctx.skills provider with
includeDefaultRoots: false and bundledSkillDir pointing at skills/. DSH
reads this host-owned bundle directly rather than asking a workspace filesystem
to resolve a path outside its root. Its existing filesystem provider still
owns the project and user skill roots; the bundle does not duplicate that
catalog or override higher-priority project skills.
OpenViking credentials use the same resolution order as the other memory plugins:
OPENVIKING_* environment variables~/.openviking/ovcli.conf~/.openviking/ov.confCommon environment variables:
| Variable | Purpose |
|---|---|
OPENVIKING_URL / OPENVIKING_BASE_URL | OpenViking server endpoint |
OPENVIKING_API_KEY / OPENVIKING_BEARER_TOKEN | Bearer credential |
OPENVIKING_ACCOUNT | Trusted-mode account |
OPENVIKING_USER | Trusted-mode user |
OPENVIKING_PEER_ID | Explicit actor peer |
OPENVIKING_WORKSPACE_PEER | Derive a peer from each DSH session workspace's git identity by default; 0 sends no peer |
OPENVIKING_RECALL_PEER_SCOPE | all for cross-workspace recall or actor for isolation |

agent/session-start injects the OpenViking profile and available-memory index through agent.inject().agent/pre-step retrieves with the current step input and appends a durable plugin message to that same step.session/event captures user, assistant, and optionally tool-result messages without scraping a transcript.turn/end checks the OpenViking pending-token threshold and commits when required.skipSubagentSessions: true excludes sessions marked with header.origin: subagent from automatic profile, recall, capture, and commit; it defaults to false.syncTurns: false stops every new write: no captured messages, no threshold or shutdown commit. Writes queued while the toggle was on are still replayed by the background drainer once the server recovers — they were captured with the toggle on. Profile injection and recall are unaffected; it defaults to true.OPENVIKING_PENDING_DRAIN_INTERVAL_MS) probes the server health and replays the queue in-process, so a transient write failure recovers without restarting dsh; it does not consume the session-start retry budget. Session-start replays keep consuming retries as before.tools/pre-execute blocks DSH filesystem and shell tools from treating viking:// URIs as local paths, pointing the model at the bridged mcp__openviking__* tools instead.Each DSH session maps to dsh-<session-id> in OpenViking. Workspace-derived actor peers are resolved per session and sent on every session-specific request: the peer is the git identity of the session's workspace — the normalized origin URL (git@github.com:volcengine/OpenViking.git becomes github.com-volcengine-openviking), else the repository root path, that fallback keeping the older rule where every non-letter-or-digit character becomes -. Outside a git repository no peer is sent at all, and what is remembered there goes to the user-level space viking://user/<you>/memories. One repository therefore keeps one peer across subdirectories, worktrees, clones and machines, while a fork's different origin keeps it separate. DSH does not read workspace .openviking/config.json files, so a peer.id written there has no effect; pin a peer with OPENVIKING_PEER_ID instead. Memories written under the older path-derived peer stay reachable: the default recallPeerScope: all sweeps every peer under the user.
The model sees the OpenViking MCP tools under the bridge's server-qualified
names — mcp__openviking__search, mcp__openviking__read,
mcp__openviking__list, mcp__openviking__tree, mcp__openviking__grep,
mcp__openviking__glob, mcp__openviking__remember,
mcp__openviking__write, mcp__openviking__edit,
mcp__openviking__forget, mcp__openviking__add_resource, and the rest of
whatever the connected server advertises. The list re-syncs when the server
announces a change, so a server upgrade adds tools without a bundle release.
mcp__openviking__forget performs permanent deletion. The calling model should
use it only when the user explicitly requests deletion.
The bundle also serves the shared openviking-memory skill from skills/
through its own isolated ctx.skills provider, so the model gets the same
guidance on when to search, read, and write that the other integrations ship.
npm ci # installs the exact-pinned dsh devDependencies the tests exercise
npm run check # syntax check every shipped module + package/PLUGIN_VERSION agreement
npm test # node --test *.test.mjs — runs in the repo's PR workflow
The 0.3.2 compatibility check installed the packed bundle through
dsh plugin add in isolated profiles and exercised DSH 0.1.0-rc.6,
0.1.5-rc.1, and 0.1.5-rc.2 with matching core packages. It covered Web startup
and browser loading, skill discovery/read, MCP tool calls, profile/recall
injection, user/assistant capture, resume deduplication, threshold commits, and
disposal commits. The check used a local HTTP/MCP fixture and a deterministic
model adapter on macOS with Node.js 26.5.0; it verifies harness integration, not
real-server memory extraction. The rc.2 CLI also exited cleanly on SIGTERM.
The startup failure from issue #4944 was reproduced by adding the reported
old skill packages to an rc.2 profile; removing those direct dependencies and
reinstalling the bundle restored the same integration checks. A clean rc.2
profile with the published 0.3.0 bundle did not reproduce that import error.
live-recall.test.mjs is an opt-in end-to-end gate against a real OpenViking
server: it stores a sentinel memory through a session commit, waits for
extraction, and asserts recall returns that sentinel — the property no stub
can certify. Enable it with OPENVIKING_E2E=1 plus the normal credential
chain; it skips otherwise (including in CI until a server secret exists).
