openviking-memory

Work with OpenViking, the persistent context database behind this agent's memory. Use it whenever the user refers to earlier sessions or shared history ("like last time", "what did we decide"), asks to remember or forget something, shares files, URLs, or repos worth keeping, or when the task needs context this session does not have — even if nobody says the word "memory". Also use it when the user asks where memories are stored: per project, per folder, or shared between repositories. Covers choosing between context search, find, list search, and grep, reading viking:// URIs, and when (not) to write.

Quality

Content

93%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A lean, well-structured instruction skill: an explicit session lifecycle, a concrete retrieval-tool decision guide, disciplined write guidance with a validated destructive path, and a precise peer-config section with copy-paste examples. The only improvement area is the absence of feedback loops (e.g., what to do when retrieval comes back empty or wrong beyond 'use search in default list mode').

Dimension	Reasoning	Score
Conciseness	Roughly 90 lines of dense operational guidance with no explanations of concepts Claude already knows; every sentence carries non-obvious decision information (lifecycle behavior, tool-selection rationale, write discipline, peer-derivation rules) and guardrails are stated tersely ("Never pass them to filesystem tools").	5 / 5
Actionability	Gives exact tool names with parameters (`search` with `mode="context"`), a copy-paste JSON config for pinning a peer, an exact environment variable (OPENVIKING_PEER_ID), and exact config keys with an explicit 'do not invent other keys' boundary — fully actionable for an instruction-only skill.	5 / 5
Workflow Clarity	The session lifecycle is an explicit four-step sequence with checkpoints (check injected context before searching; expand hits with `read` before relying on them), and the destructive `forget` operation includes validation ('Confirm with the user and pass the exact URI; never delete from a fuzzy match'). It falls short of anchor 5 only because there are no error-recovery feedback loops for the retrieval workflow.	4 / 5
Progressive Disclosure	A well-sectioned overview where advanced material is deferred one level deep via clearly signaled references (the `openviking-skills` skill, the `ov-experience-memory` skill, and external doc URLs for CLI setup and the full documentation index), while everything inlined is decision-critical for normal use.	5 / 5

Description

95%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete natural-language triggers with quoted colloquialisms, explicit 'Use it whenever' guidance covering direct and indirect invocations, and a clear statement of what the skill covers. The only minor gap is that the capability list summarizes tool selection rather than comprehensively enumerating operations such as add_resource or add_skill.

Dimension	Reasoning	Score
Specificity	Names the domain ("persistent context database behind this agent's memory") and several concrete actions ("choosing between context search, find, list search, and grep, reading viking:// URIs, and when (not) to write"), but does not enumerate capabilities like add_resource or add_skill, leaving minor gaps in coverage.	4 / 5
Completeness	Explicitly answers both what ("Work with OpenViking, the persistent context database... Covers choosing between context search, find, list search, and grep, reading viking:// URIs, and when (not) to write") and when ("Use it whenever the user refers to earlier sessions or shared history... shares files, URLs, or repos... when the task needs context this session does not have") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural colloquial trigger phrases users would actually say ("like last time", "what did we decide", "asks to remember or forget something", "where memories are stored") plus synonyms ("earlier sessions", "shared history") and explicit coverage of indirect triggers ("even if nobody says the word 'memory'").	5 / 5
Distinctiveness Conflict Risk	A clear niche (OpenViking memory store, viking:// URIs, cross-session recall) with distinctive trigger phrases; minimal risk of firing for the wrong skill.	5 / 5
