name: openviking-memory
description: Recall and persist long-term memory through the OpenViking MCP tools. Use at the start of any substantive task (coding, configuration, debugging, multi-step or tool-based work) to retrieve relevant prior knowledge with find/search/read, and during or after work to persist durable facts, preferences, decisions, and lessons with remember/write. Do not use for casual chat or simple factual questions the model can answer directly.

# OpenViking Memory
OpenViking is a long-term semantic memory store addressed by `viking://` URIs.
This client has no lifecycle hooks, so nothing is recalled or captured
automatically — you drive both halves of the loop with the `openviking` MCP
tools:
- - Recall: `find`, `search`, `recall`, `read`, `list`, `tree`, `grep`, `glob`
+ - Recall: `find`, `search`, `read`, `list`, `tree`, `grep`, `glob`
- Persist: `remember`, `write`, `edit`, `add_resource`
- Maintain: `forget`, `health`
Use only the tools the session actually registered — the exact set depends on
the server version, and `tree`, `write`, and `edit` are absent on older
deployments. If no OpenViking tools are registered at all, continue without
memory. Do not fabricate tool calls or fall back to raw HTTP.
## Recall: at task start
1. Decide whether the request warrants memory. Retrieve for executable or
multi-step work, anything touching a system you may have seen before, and
recovery from failures. Skip retrieval for small talk and one-off trivia.
2. Build one concise query from the task goal, domain objects, intended
operation, and constraints. After a failure, include the failed operation
and the stable part of the error message.
3. Call `find` (fast, ranked results with URI + abstract + score) with
- `limit` around 5-10. Use `search` when deeper intent analysis helps, or
- `recall` for a server-assembled, token-budgeted context block. Scope with
- `target_uri` when you know where to look, e.g.
+ `limit` around 5-10. Use `search` when deeper intent analysis helps, or use
+ `search` with `mode="context"` for a server-assembled, token-budgeted
+ context block. In list mode, scope with `target_uri` when you know where to look, e.g.
`viking://user/memories/experiences` for prior task experience.
4. Judge results by task and environment fit, not title similarity. `read` the
one to three exact file URIs likely to change how you execute. Ignore
sidecar files such as `.abstract.md`, `.overview.md`, and
`.relations.json`.
5. If nothing relevant comes back, proceed without memory. Make at most one
focused follow-up search when execution fails for a materially new reason.
Treat retrieved memory as advisory. Priority order: system and developer
instructions, the current user request, current environment and tool evidence,
then memory. Verify commands, paths, and versions against the present task;
prior success never authorizes a destructive action now.
## Persist: during and after work
Because capture is not automatic here, durable information is lost unless you
store it. When you encounter something worth keeping, persist it in the same
session:
- `remember(messages)` — the default. Pass the key exchange or a short factual
summary as role-tagged messages; the server extracts and files memories
(preferences, entities, events, experience) on its own. Use it when the user
says "remember this", states a lasting preference or decision, or when a
hard-won lesson (root cause, working procedure, environment quirk) emerges.
- `write(uri, content)` / `edit` — when you need an exact document at a known
location, such as curated notes under `viking://user/` or shared reference
material under `viking://resources/`. Prefer `edit` over rewriting whole
files. If neither tool is registered, fall back to `remember`.
- `add_resource` — to import external documents or URLs as searchable
resources.
What to persist: stable preferences and conventions, environment facts,
decisions with their rationale, and reusable procedures or fixes. What not to
persist: secrets and credentials, transient state, speculation, or bulk
transcript dumps — store conclusions, not scrollback.
## Example
User asks to fix a failing deployment:
1. `find` with query `deployment image pull failure private registry`,
`target_uri: "viking://user/memories/experiences"`.
2. `read` the most relevant experience URI; check its assumptions against the
current cluster before applying its steps.
3. Fix the issue, verify the live result.
4. `remember` a short summary of the root cause and the working fix so the
next session can recall it.
