Reference guidance for OpenViking setup and layered-memory migration in Aeloon.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Openviking Memory is an agent skill from AetherHeart-AI/Aeloon. Reference guidance for OpenViking setup and layered-memory migration in Aeloon. Runtime usage should rely on provider-native viking tools, not this skill.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is MIT.

Example prompts

  • “/openviking-memory”

What it can do on your machine

Read from SKILL.md and the folder at commit e5afaa1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Openviking Memory loads about 243 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 96 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~243

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

OpenViking Setup And Migration

  • OpenViking is additive in Aeloon. Prompt memory in memory/MEMORY.md and memory/USER.md stays active, and transcript recall still belongs to session_search.
  • When the OpenViking provider is enabled, the primary runtime surface is the provider-native tool set:
    • viking_search
    • viking_read
    • viking_browse
    • viking_remember
    • viking_add_resource
  • Use this skill only for setup, migration, or explanation tasks. Do not treat it as the main control plane for OpenViking operations.
  • If the user asks how the layers fit together, explain them in this order:
    • prompt memory for small durable facts
    • session archive for transcript recall
    • OpenViking for additive semantic/provider-native knowledge
