OpenViking is an open-source context database for AI agents that stores memories, resources, and skills in a browsable virtual filesystem. Agents use it to find and load relevant context in layers while inspecting how retrieval decisions were made.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.00628 |
| Opus 5.5 | $0.00038 | $0.00251 |
| Sonnet 5.5 | $0.00019 | $0.00126 |
| Haiku 4.5 | $0.00009 | $0.00063 |
Grade A, and why
github-proxy scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Licensed AGPL-3.0
The repository is licensed AGPL-3.0, which this catalogue does not treat as permission to reproduce the file. Read it at the source.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

github-proxy is a skill published in the GitHub repository volcengine/OpenViking (40,015 stars, last pushed today), licensed AGPL-3.0. It adds 94 tokens to every session and 628 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
wiki
Decision-sensitive repository knowledge retrieval, authoring, maintenance, and trust audits using wiki-manager when available or an explicit local-file fallback. Use when repository knowledge could change a non-trivial decision or when the user mentions wiki, knowledge base, packets, schema reports, or wiki tools.
gsd-forensics
Post-mortem investigation for failed GSD workflows — analyzes git history, artifacts, and state to diagnose what went wrong.
gsd-new-workspace
Create an isolated workspace with repo copies and independent .planning/.
gsd-quick
Execute a quick task with GSD guarantees (atomic commits, state tracking) but skip optional agents.
gsd-pr-branch
Create a clean PR branch by filtering out .planning/ commits — ready for code review.
gsd-remove-workspace
Remove a GSD workspace and clean up worktrees.
