By name: openviking-context-database description: > Use OpenViking from OpenClaw through @openviking/openclaw-plugin: long-term memory, session archives, resource and Agent Skill import, semantic recall, recall trace debugging, and externalized tool-result recovery. Prefer this skill when the user wants to use, query, debug, or operate OpenViking context from an OpenClaw agent.

OpenViking Context Database — OpenClaw Plugin Operator Skill
Use this skill after @openviking/openclaw-plugin is installed and configured. It describes the current OpenClaw plugin implementation, not the standalone OpenViking Python SDK.
Scope and Safety Rules
- The plugin is remote-only. It talks to an existing OpenViking server through HTTP and does not start or manage
openviking-server. - Do not invent OpenViking REST endpoints. Use the registered OpenClaw tools and commands described below.
- The agent-visible
add_resourcetool is disabled by default (enableAddResourceTool=false). Do not useadd_resourceduring search, retrieval, URI reading, or search-result optimization. Useov_searchandov_readin those flows. - Use manual
/add-resource, oradd_resourceonly when it is explicitly enabled and the user explicitly asks to import, add, upload, save, or index a resource. - Use
add_skillonly when the user explicitly asks to import, add, install, or register an Agent Skill into OpenViking. - For local files and directories, pass the local path to the plugin tool. The plugin uploads them through
/api/v1/resources/temp_upload; do not send raw local filesystem paths to a remote server yourself. - Never log or echo API keys. The plugin sends API keys as
X-API-Key/ setup probe headers and masks them in setup output.
Current Architecture
OpenClaw owns agent execution, prompts, and tool invocation. OpenViking owns long-lived context:
| Layer | Current behavior |
|---|---|
assemble |
Rebuilds compressed session history from OpenViking and injects relevant recall into the latest user message. |
afterTurn |
Appends only the new turn to the OpenViking session; may trigger async commit when pending_tokens >= commitTokenThreshold. |
compact |
Runs commit(wait=true), waits for archive/extraction completion, and reads back latest archive overview. |
| Tools | Memory recall/store/forget, archive search/expand, resource/skill import/search, recall trace query, tool-result list/search/read. |
Long-term memories are usually extracted on /compact or on threshold-triggered commit. A fact mentioned in a fresh conversation may still be present as recent session context before it becomes a long-term memory.
Configuration Quick Reference
Read status first:
openclaw openviking status --json
openclaw config get plugins.entries.openviking.config
openclaw config get plugins.slots.contextEngine
Core config lives under plugins.entries.openviking.config:

apiKey |
empty | Optional API key. Can also come from OPENVIKING_API_KEY. |
peer_role |
assistant |
Peer identity mode: none, assistant, or person. Session messages use body peer_id; data-plane recall/search uses X-OpenViking-Actor-Peer. |
peer_prefix |
empty | Optional prefix for assistant peer_id / actor peer values when peer_role=assistant. |
accountId / userId |
empty | Advanced tenant identity headers for root-key or trusted deployments. |
targetUri |
viking://user/memories |
Default search scope for legacy targeted memory search. |
autoCapture |
true |
Append sanitized turn text to OpenViking sessions. |
captureMode |
semantic |
semantic or keyword; affects server-side extraction filtering. |
captureMaxLength |
24000 |
Max sanitized text length per captured turn. |
autoRecall |
true |
Run recall before replies and inject relevant context. |
recallTargetTypes |
user,agent |
Default target types when targetUri is omitted. Allowed: resource, user, agent. |

Tool Interface Reference
memory_recall
Semantic search over memories/resources. Use archive tools for session history.
| Parameter | Required | Description |
|---|---|---|
query |
Yes | Search query. |
limit |
No | Max selected results. Defaults to recallLimit. |
scoreThreshold |
No | Score threshold 0..1. Defaults to recallScoreThreshold. |
targetUri |
No | Exact search URI. If set, only this URI is searched. |
resourceTypes |
No | Array of resource, user, agent; used only when targetUri is omitted. |
Notes: when targetUri is omitted, the plugin resolves a search plan from resourceTypes or configured recallTargetTypes, fetches more candidates than requested, deduplicates, filters leaf memories, reranks, and respects recallMaxInjectedChars.
memory_store
Persist text immediately by writing a session and committing with wait=true.
| Parameter | Required | Description |
|---|---|---|
text |
Yes | Information source text. |
role |
No | Session role, default user. |
sessionId |
No | Existing OpenViking/OpenClaw session reference. If omitted, a temporary memory-store-* session is created. |
memory_forget
Delete a memory.
| Parameter | Required | Description |
|---|---|---|
uri |
No | Exact viking://user/.../memories/... memory URI. Non-memory URIs are refused. |
query |
No | Search query when uri is unknown. |
targetUri |
No | Search scope URI, default targetUri. |
limit |
No | Search limit, default 5. |
scoreThreshold |
No | Search threshold, default recallScoreThreshold. |
If query mode finds multiple candidates, report candidates and ask the user to choose the exact URI; do not delete ambiguous memories.
ov_archive_search
Keyword grep across archived original conversation messages of the current session.
| Parameter | Required | Description |
|---|---|---|
query |
Yes | Single keyword or short phrase; prefer names, dates, file paths, commands, or distinctive nouns. |
archiveId |
No | Restrict to one archive, e.g. archive_002. |
Try at least two concrete keyword variants before concluding archived detail is unavailable.
ov_archive_expand
| Parameter | Required | Description |
|---|---|---|
archiveId |
Yes | Archive ID from [Archive Index], e.g. archive_002. |
Use after an archive search or when the [Archive Index] already identifies the archive likely to contain exact detail.
add_resource
Import resources into viking://resources/....
This agent tool is disabled by default. Prefer manual /add-resource for resource ingestion. If enableAddResourceTool=true exposes the tool, use it only for explicit import/index requests and never as part of search/retrieval optimization.
| Parameter | Required | Description |
|---|---|---|
source |
Yes | Local path, OpenClaw media attachment path, directory path, public URL, or Git URL. |
to |
No | Exact target URI, e.g. viking://resources/project-docs. Mutually exclusive with parent. |
parent |
No | Parent URI under viking://resources. Mutually exclusive with to. |
reason |
No | Reason/note for import. |
instruction |
No | Processing instruction for semantic extraction. |
wait |
No | Wait for processing completion. |
timeout |
No | Timeout in seconds when wait=true. |
The current OpenClaw tool exposes the parameters above. The underlying client also supports server-facing resource options such as strict, ignore_dirs, include, exclude, and preserve_structure for command/internal paths; do not pass them to the tool unless the registered schema exposes them.
add_skill
Import Agent Skills into viking://user/skills/....
| Parameter | Required | Description |
|---|---|---|
source |
No | Local SKILL.md path or skill directory. Exactly one of source or data is required. |
data |
No | Raw SKILL.md content or an MCP tool dict. Exactly one of source or data is required. |
wait |
No | Wait for processing completion. |
timeout |
No | Timeout in seconds when wait=true. |
Agent Skill best practice: a skill should have precise frontmatter (name, trigger-oriented description, useful tags), clear scope boundaries, explicit “when not to use” guidance if needed, and executable steps with concrete parameters. Keep secrets out of skill content.
ov_search
| Parameter | Required | Description |
|---|---|---|
query |
Yes | Search query. |
uri |
No | Search URI. Defaults to resources plus agent skills. |
limit |
No | Max results per scope, default 10. |
Use after importing resources/skills, or when the user asks to search OpenViking-managed knowledge.
Important: ov_search returns OpenViking virtual URIs such as viking://resources/project-docs/api.md#chunk-3. These are not local file paths. Do not use filesystem read tools for them; call ov_read with the exact URI when full content is needed.
ov_read
Read full content for one exact OpenViking virtual URI through /api/v1/content/read.
| Parameter | Required | Description |
|---|---|---|
uri |
Yes | Exact viking://... URI returned by ov_search or recall trace results. openviking://... aliases and local file paths are refused. |
ov_recall_trace
| Parameter | Required | Description |
|---|---|---|
turn |
No | latest or all, default latest. |
traceId |
No | Exact trace ID. |
sessionId / sessionKey / ovSessionId |
No | Filter by OpenClaw/OpenViking session. |
source |
No | auto_recall, memory_recall, ov_search, or ov_archive_search. |
resourceTypes |
No | Array/string containing resource, user, agent. |
since / until |
No | Unix timestamp bounds in milliseconds. |
includeContent |
No | Read selected/displayed URI content previews on demand. |
limit |
No | Maximum traces to return, default 20. |
Trace records exist only when traceRecall=true; persisted lookup requires traceRecallPersist=true and accessible trace files.
Externalized tool-result tools
Use when a preview contains viking://session/<session_id>/tool-results/<tool_result_id>.
| Tool | Parameters |
|---|---|
openviking_tool_result_list |
tool_name?, limit? (default 50) |
openviking_tool_result_search |
tool_output_ref, query, limit? (default 20), context_chars? (default 300) |
openviking_tool_result_read |
tool_output_ref, offset? (default 0), limit? (default 20000, -1 accepted by server path for all remaining content) |
The plugin refuses to read/search a tool-result ref from another session.
Slash Commands
/add-resource ./README.md --to viking://resources/openviking-readme --wait
/add-skill ./skills/install-openviking-memory --wait --timeout=30
/ov-search "OpenViking install" --uri viking://resources/openviking-readme --limit=5
/ov-recall-trace --turn latest --source auto_recall --include-content
Command parsers support quoted args and flags. Resource-only flags are rejected for skill imports.
Troubleshooting
| Symptom | Likely cause | First action |
|---|---|---|
configured=false |
Setup did not persist config | Re-run openclaw openviking setup ... --json; branch on JSON error. |
slotActive=false |
Another context engine owns the slot or gateway has stale state | Inspect plugins.slots.contextEngine; use --force-slot only after user confirms. |
health.ok=false |
Server unreachable or wrong baseUrl / key |
Check baseUrl, network, /health, and auth. |
| No long-term memory after a fresh fact | /compact or commit/extraction has not run, or server extraction failed |
Run /compact; check OpenViking server logs. |
| Recall misses shared documents | resource target is not enabled |
Use memory_recall with resourceTypes:["resource"] or configure recallTargetTypes: ["resource"]. |
| Summary lacks exact detail | Archive summary is too coarse | Use ov_archive_search with concrete keywords, then ov_archive_expand. |
| Large tool output preview is insufficient | Tool result was externalized | Use openviking_tool_result_search/read with the ref. |
| Need to explain recall behavior | Trace disabled or no trace for that turn | Enable traceRecall; optionally traceRecallPersist; query ov_recall_trace. |
