How to install claude-obsidian

git clone https://github.com/AgriciDaniel/claude-obsidian
claude plugin install claude-obsidian@claude-obsidian-marketplace

Taken from the project's README on GitHub. Check the security audit before running it.

Security audit verdict: SAFE · quality 70/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours. Full audit →

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

🧪 Tested by Agent Skills Hub

One of 5 tools we ran end to end on the same task for our Obsidian for Claude Code & AI Agents page (2026-10-10).

Our pick (If you work in Claude Code and want a vault workflow): The cheapest of the tools that ran (about 1.7 times the control). It did not change how questions get answered: Claude Code read the notes with its own tools. Install it for the note-taking workflow, not for recall.

Result: The skill was loaded once; the searching and reading were done with Claude Code's own file tools. · answered 15 of 15 questions about a test vault · 1.7× the tokens of plain file tools · 1 calls through the tool, 7 through plain file tools

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
