What is ariadne:vault?

A setup for a long-lasting collection of Markdown notes, templates, instructions, and navigation files. It can support projects, research, learning, and personal systems; Obsidian, a note-taking app, is optional.

Use it to create or refresh a Markdown knowledge collection, add its basic folders and templates, and connect it to agent instructions and navigation.

It gives an AI agent a consistent place and structure for storing and finding knowledge over time instead of starting from scattered files.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Rogue Agent · line 8
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

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	$0.00065	$0.02548
Opus 5	$0.00032	$0.01274
Sonnet 5	$0.00013	$0.00510
Haiku 4.5	$0.00006	$0.00255

Security

Grade A, and why

ariadne:vault scanned grade A with 0 findings 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 8d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/register_vault.js, test/test_register_vault.js, test/test_research_templates.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ariadne Vault

Use this skill to create or refresh a durable, agent-maintained Markdown knowledge vault. Obsidian is an optional, recommended frontend rather than a runtime requirement.

This skill complements Obsidian mechanics skills:

Use obsidian-markdown for notes, properties, wikilinks, embeds, and callouts.
Use obsidian-bases for .base views.
Use json-canvas for .canvas maps.
Use defuddle for clean Markdown extraction from web pages.
Use obsidian-cli when Obsidian is open and CLI interaction is useful.

It also has workflow companion skills:

ariadne:knowledge-capture for raw inputs, links, documents, and brain dumps.
ariadne:global-discovery for registering existing vaults so cold agents can find them from any workspace.
ariadne:workspace-instructions for creating or updating workspace-level AGENTS.md, CLAUDE.md, or GEMINI.md files that connect a workspace to registered Ariadne context.
ariadne:research-ingest for cold-start research sources, target confirmation, and write-set orchestration.
ariadne:research-synthesis for multi-source research disposition and inquiry history.
ariadne:research-stewardship for audit-first research-boundary health and allowlisted repairs.
ariadne:research-pipeline for adding research intake and synthesis infrastructure inside an existing scope.
ariadne:workstream-tracking for Kanban work boards, Dataview dashboards, and workstream status tracking.
ariadne:closeout for post-work capture, checkpoints, handoffs, and safe-to-close decisions.
ariadne:maintenance for health checks and recurring maintenance.
ariadne:navigation for hubs, routing, workstream graphs, and Base/view-layer changes.

Prerequisites

Before bootstrapping or refreshing a vault, confirm the user has:

A target vault folder available on disk.
Optional: Obsidian installed when the user wants its native frontend.
Optional: Obsidian Bases enabled when the vault should render .base dashboards.
Node.js available for the validator and scripts/register_vault.js.
A skills-capable agent runtime.

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.
